Apple CarPlay Explained

Apple CarPlay

According to a AAA survey, the average American drives for about 45 minutes each day. If you compare this time to an eight hour work day, that’s 10% of your work day, on top of the hours you are at your desk. This time is not an insignificant number. If your job involves being on the road, then your time spent behind the wheel can represent half of your day. Being able to be productive while in your vehicle is not only convenient, but in some cases, mandatory to get all the work you need to get done in one day completed. Modern smartphone integration comes to the rescue with Apple CarPlay.

Apple CarPlay History

Apple recognized the need to give people the ability to use their phones in a safe fashion while driving back in 2010. The feature was called iPod Out. BMW announced that it would include iPod Out at the WWDC that year. The concept was that BMW would provide a way for its vehicles to ‘host’ specific applications. The information would be displayed on the factory screen while providing button press and knob rotation information back to the radio.

Apple CarPlayThe next evolution was the introduction of Siri Eyes Free in some Honda Accord and the Acura RDX and ILX models in 2013. Siri Eyes Free is a way to make use of the Siri voice recognition function that Apple Introduced with iOS 5 and the iPhone 4S in October 2011. Apple has marketed Siri as a personal assistant. It allows you to talk to your Apple device to make phone calls, send text messages, set reminders and choose the music you want to hear. Using Siri Eyes Free is simple- press and hold a button on your car radio, wait for the tone, and then speak.

Siri will listen to what you said, convert that to a command and execute it, all without you needing to take your eyes off the road.

Between the time that Apple announced iPod Out and the Geneva Motor Show in March of 2014, Apple was working on the next generation of automotive integration under the code name Stark. At the Geneva Motor Show, they announced ‘iOS in the Car.’ Later that year, Ferrari introduced the new FF model with a fully working version of Apple CarPlay. A few months later, Hyundai announced the Sonata would also feature CarPlay. Most automobile manufacturers have CarPlay available on their mid to high trim level vehicles now.

Apple CarPlay Interface Overview

Apple CarPlay
CarPlay alerts you to new text messages and will read them to you.

Apple’s current marketing touts CarPlay as ‘The Ultimate Copilot.’ The features are designed to allow you to communicate with family, friends, and coworkers without significant distraction. The basic feature set of CarPlay includes making and receiving phone calls, choosing the music you want to listen to, getting navigation instructions and sending and receiving text messages.

Apple has worked hard to ensure that the above functions are usable without unnecessary distraction. As soon as you plug your phone into the USB port of your radio, CarPlay launches automatically.

CarPlay does not display incoming text messages on the screen of the radio. Messages are read aloud to prevent users from looking at the dash. However, there are no options presented when asking Apple Maps to plan a navigation route.

Apple CarPlay
Voice command of music selection keeps driving and listening safe.

Selecting music to play is as easy as requesting the track title, artist or even genre of music you want to enjoy. CarPlay will start playing what you want right away. Apple has also included support for Apple Music- a streaming service powered by iTunes. CarPlay also supports Apple Podcast and Audiobooks. You can select the episode you want to listen to via the touchscreen interface, then play, pause or skip 15 seconds forward or back. Apple CarPlay provides support for several third-party applications including Pandora, Spotify, iHeartRadio, Audible and MLB At Bat.

Apple has released information to application developers in order to allow for the creation of more third party applications. You will see more and more third-party applications added to the CarPlay interface as time passes. Apple will, of course, be selective in their approval process, so don’t expect to see competing navigation applications any time soon.

The Future of Apple CarPlay

Apple CarPlayUnveiled by BMW in October of 2016, future iterations of CarPlay will function wirelessly. The 2017 BMW 5-Series sedans, when used with an iPhone 6 or newer, will allow users to use CarPlay without the need to plug in the Lightning connector. Wireless CarPlay communicates over a Bluetooth data connection.

Apple is tight-lipped about future functionality of CarPlay. There have been rumours about vehicle function control like remote door lock control, remote starting and trunk release, but so far nothing is set in stone. Another rumored feature is the ability of your phone to remember where you parked your car once you have arrived at your destination.

Apple has led the industry with safe and convenient integration of your smartphone to your vehicle. The future of ‘connected cars’ promises to allow us to share information and offer better communication while remaining safe. If you are interested in adding CarPlay to your vehicle, visit your local mobile electronics specialist retailer. They can show you what options are available for your vehicle.

Product Spotlight Hertz Mille Legend Speakers and Subwoofers

Hertz Mille Legend

In 2005, Hertz introduced the world to the Mille series of car audio speakers and subwoofers. These unique drivers featured the V-cone design to deliver impressive clarity and detail. Now in their third generation, Mille Legend tweeters, midrange drivers, woofers and subwoofers combine premium materials with state-of-the-art technologies to ensure that music enthusiasts can enjoy their music at elevated volume levels in amazing clarity and detail. Let’s take a close look at the technologies Hertz has implemented in its flagship speaker products.

Hertz Mille Legend Speakers – Moving Parts Technologies

From the detailed ML 280.3 Legend tweeter to the impact of the ML 2500.3 Legend subwoofer, the Hertz Mille Legend speaker family uses modern design elements and technologies that reduce distortion and improve performance.

The deep V-cone design is evident if you look at any Mille Legend midrange drivers, woofers or subwoofers. This one-piece cone design comes to a sharp inverted point in the center. Unlike a typical dome-shaped dust cap, the V-cone design resists resonance that can add distortion to the music signal. Hertz also claims that the design helps to improve off-axis performance, making a two-way speaker set sound better in the doors or dash of your car or truck.

Hertz Mille Legend
The deep V-cone design of the Mille Legend drivers helps deliver smooth upper-frequency response that isn’t tainted by conventionally shaped dust cap resonance.

The Boundary Free Surround design on all the drivers helps to reduce unwanted resonance and increase the effective area of the woofer cone. These surrounds are constructed from high-purity IIR butyl rubber that resists degradation from prolonged exposure to oxygen and ozone.

The stand-alone and coaxial tweeters use a diaphragm made from Hertz’ proprietary Tetolon fiber cone material. This lightweight textile provides an amazing balance of clarity and high-frequency extension. In addition, the inherent damping characteristics resist the addition of unwanted distortion at the highest of frequencies. The midrange drivers in the Legend series use cotton-damped pressed pulp paper cones that offer a near-perfect balance of rigidity and resonance-preventing damping. The subwoofers use a mineral-injected paper cone for added strength alongside the excellent damping characteristics.

Hertz Mille Legend
All the tweeters in the Mille Legend series feature Tetolon fiber diaphragms to deliver smooth performance.

To prevent power compression, Hertz has implemented large-diameter voice coil assemblies on all the drivers. There is a massive 4-inch coil in the 10-inch ML 2500.3 Legend and 8-inch ML2000.3 Legend subwoofers. There’s also the large-for-the-driver-size 0.8-inch coil in the 3-inch ML 700.3 Legend midrange speaker. Larger voice coils offer a significant increase in surface area that helps them dissipate heat and stay cooler.

Hertz designed this series of speakers using computer-based Finite Element Analysis (FEA) to optimize the connection between the voice coil former and the cone in all the midrange, woofer and subwoofer solutions. Ensuring that this crucial connection is both mechanically secure and thermally stable is another reason why the Mille Legend speakers sound great, even at high volume levels.

Motor and Basket Performance Features

All but the two coaxial drivers in the Legend series use neodymium ring magnets at the core of their motor design. These rare earth magnets help the speakers and tweeters deliver impressive efficiency without the need for large, heavy motors. The design also helps to reduce the overall depth of the drivers. Along the same theme, the top and back plates are forged and milled from low-carbon steel, which offers excellent magnetic permeability to further increase efficiency.

All the Mille Legend drivers use copper or aluminum shorting rings to help improve high-frequency performance. These rings short unwanted magnetic fields created as the voice coil assembly moves through the magnetic gap. In the midrange drivers and woofers, upper midrange clarity is dramatically improved, thanks to this technology. In addition, midbass performance on the subwoofers and enhanced tweeter clarity at the top end of the audible spectrum are also achieved.

Hertz Mille Legend
Legend woofers and subwoofers include copper or aluminum shorting rings to improve linearity and decrease distortion.

Hertz Mille Legend subwoofers, woofers and midrange drivers are based on cast aluminum chassis that help ensure that every component is aligned perfectly. The design also serves as a heatsink to improve power handling and to isolate the cone and motor from vehicle vibrations while driving.

Hertz Mille Legend
Rigid cast baskets with integrating cooling/pressure vents under the spider mounting plateau ensure consistent and linear output, even at high volume levels.

Upgrade Your Car Audio System with Hertz Mille Legend Speakers

If you’re shopping for new or upgraded speakers for your car audio system, visit your local authorized Hertz retailer and ask for a demonstration of the Hertz Mille Legend drivers. You can learn more about the impressive products from Hertz by visiting their website, Facebook page or their YouTube channel.

The Reference For Great Sound

Great SoundListening to music goes back to the dawn of man. From banging a few tree branches together to the latest computer-generated pop hit, music is a universal language that everyone can enjoy. People who put significant effort into the accurate reproduction of the music they enjoy are often called audiophiles. There is a running joke that audiophiles sometimes concentrate more on listening to the equipment they use to make great sound than to the music itself. While this so-called joke is certainly true during the purchasing and setup stage, once audiophiles have their systems sounding the way they want, the focus turns to enjoying the music.

If you get into a discussion about choosing high-end audio equipment, inevitably someone will suggest that you seek out a reference. The ultimate reference is a live performance. We want to be clear: Artists don’t make money like they used to from album sales. Supporting the performers you enjoy by attending concerts not only is great entertainment for you, but allows the performer to make a few dollars.

With this in mind, the reference for what the reproduction of a recording should sound like is not a live performance.

This article provides a generalization about most music heard on a car radio. There are exceptions; we understand that. We want you to think outside what you were once told.

How Music is Recorded

Great SoundFor most music, each musician or performer is in a recording studio. Microphones are used to capture the subsequent performance. For a singer, the mic is usually directly in front of them. For a group of singers, each individual may have a mic, or they may be gathered around a single centralized mic or a pair of microphones set up to capture the performance in stereo. For someone playing an electric guitar, the mic is most likely in front of the amplifier.

In some recording sessions, the amplifier is placed in a small room and cranked to 11 so it clips and distorts the sound, and that gets recorded. This overdriven performance gives the guitar “a certain sound” that some producers and engineers like.

Great SoundThese techniques go on and on. At the very extreme might be a drum kit. Some recording engineers have microphones on each drum and cymbal, then overhead mics to pick up rim shots and another set of mics forward of the drums to capture the room’s acoustics. Consider this as well: The sensitivity pattern of a microphone is not so narrow that it only captures what is directly in front of it, so each microphone captures information from all of the drums and cymbals, to some extent.

The specific placement of a microphone relative to the instrument it is recording has a dramatic effect on what it captures. Let’s take a look at recording an acoustic guitar. A microphone a few inches in front of the soundhole will capture significantly different information than if the mic is located halfway up the fingerboard. The question now becomes, What microphone position is correct? The next question is, If we were standing in the recording studio with the guitarist, would we hear the same thing that the microphone recorded?

The Effect of the Studio

Great SoundEach make and model of instrument has its own unique characteristic set of harmonics that gives it a “sound.” So, too, does each studio. Some are very large with acoustically absorbent surfaces. Some are very small and have a “live” sound. Placing the same performer with the same instrument in each of these studios will result in a different sound in the listening and recording position. If you haven’t seen it, watch the Foo Fighters’ documentary, “Sonic Highways.” It provides a great look at how different studios can affect the sound of a performance.

Let’s review what we have so far. For a given performance, we have a unique performer, their choice of instrument, the environment, the choice of microphone and the microphone placement that affect what we hear. We are just warming up!

The Control Room

Great SoundIn a studio, the musicians perform in what is called the live room or sometimes an isolation booth. We already know that the shape, size and finish of these rooms affect what gets recorded, but what about the control room? This is a separate room from where the performance is taking place and where the recording engineer and producer typically sit. In this room are the control console, computers to capture and process the recording, and – most importantly – monitor speakers.

In a gross and undetailed generalization, once each microphone channel has been recorded, the producer manipulates each channel to produce the final mix. This manipulation can be as simple as the left-to-right panning and level of each instrument, or as complex as equalization, compression, gating, adding distortion and much more. Often, many processes are applied simultaneously to each channel. It can take weeks or months to mix a single complex track.

We all know how different each and every set of speakers can sound. When we add the acoustics of the control room to the mix (pun intended), the number of variables increases dramatically. Listening to the same master track in two different control rooms can result in dramatically different results. This begs the question once again of what is correct, and how do we know?

Measuring and calibrating the frequency response of the monitoring speaker system will certainly help a lot, but that doesn’t account for the distortion characteristics of the speakers. Let’s say the speakers sound a little warm because the midbass driver has a resonance problem due to nonlinearities in the spider. Even a mild resonance can wreak havoc with the perceived balance of the speaker. Worse, you can’t EQ it back out. Yes, you can flatten the overall response level of the system, but if you are getting some 120 Hz content because the cone is playing 60 Hz, that can’t be removed. Lack of distortion in speakers is crucial to accurate reproduction.

Circle of Destruction?

So, we have our performers in a studio playing music. Microphones are set up in specific locations to capture that performance and the acoustics of the environment. The recording engineer is listening to what is captured by the microphones on that studio’s monitor system. The engineer makes adjustments to the mix based on what he hears. The music is then sold to the public. We listen to it on our reference systems and, if everything has gone according to plan, we enjoy it.

But what if we don’t enjoy it? What if we think what we hear doesn’t have enough bass or has too much high-frequency information? Do we make adjustments to the tone controls on our radios? Does the act of attempting to reproduce sound evolve from a scientific task to a form of art?

What about the Live Performance?

Great SoundOur friends and experts suggested that our reference for listening to music be a live performance. Is it an acoustic performance? Is it in an open-air stadium or a small club? Are any band members drunk? The number of variables that can affect what we hear is nearly infinite. Your best hope of using a live performance as a reference is to listen to a recording of that particular performance. If the recording took place anywhere else, it just might not work. Will the experience be worthwhile and enjoyable? The answer to that is a resounding yes! That performance is not our reference.

What is our Reference For Great Sound?

Great SoundFor a given performance in a given location with a specific set of instruments and microphone placement techniques, the absolute reference for what that performance should sound like would be the control room where the final mixing took place. Even if we expanded our example to a simple two-microphone recording of a choir in a massive cathedral, the recording engineer is likely to make some small adjustments, using a reference audio system or reference headphones, before that recording is released to the public.

Reproducing and listening to music is about more than just frequency response. Time response, reflections in the listening environment and much more affect what we hear. The best way to develop a reference is to listen to the same recording on as many great systems as you can. Ignore the make, model, color and cost of the equipment you are auditioning. Work to quantify the difference between what you hear and what you have heard previously.

After a while, you will start to develop a reference for what sounds good. Continue to listen. Evaluate new products, new applications and new environments. Sure, a personal preference is still involved, but that is your contribution to the art of recording and enjoying music: You can make it sound the way you want.

Your local specialist mobile electronics retailer will have many different systems you can audition. Drop by and ask to listen to a few. If they have a demo car, then definitely listen to that! Listening to music is a lot of fun – never forget that.

Product Spotlight: Audison Speaker Upgrades for BMWs and Minis

Audison BMW

BMW and Mini owners all over the globe have shown that there is a desire for a better sounding audio system in their vehicles. To meet the performance expectations of these discerning clients, Audison of Italy has developed six drop-in upgrades designed specifically for these vehicles. Best of all, the speaker and subwoofer upgrade solutions use factory wiring and mounting locations, so there are no modifications required. These are the perfect solution for leased vehicles!

Balancing Performance and Efficiency

Designing a loudspeaker requires that the engineer balance low-frequency and high-frequency extension with efficiency and output capability. For example, the upper midrange output may suffer if a driver is optimized to produce more bass. The engineers at Audison have optimized all these criteria for their Prima Series drivers to deliver amazing performance installations using small to moderately powerful amplifiers. As such, their BMW speakers are a perfect stand-alone upgrade with the factory radio or amplifier, or when used with a much more powerful solution like the 85-watts-per-channel AP F 8.9 bit DSP-equipped amplifier.

BMW Speaker Upgrade Solutions

The BMW speakers are broken into two categories: coaxial and component sets. So whether you have a new 2-series and want to upgrade the door speakers or are looking for the dash, front and rear speakers along with a subwoofer upgrade for a 2015 X5 with the Hi-Fi Sound system, there’s a solution from Audison.

The four speaker options are all based on the same basic platform. The 4-inch (100 mm) drivers feature high-quality rigid die-cast aluminum frames that include specific mounting provisions for the doors, the dash center channel or the rear parcel shelf of your BMW or Mini.

To deliver excellent efficiency, the drivers use neodymium magnets instead of conventional ceramic units. The woofer cones are constructed from pressed pulp paper to deliver an excellent balance of rigidity and damping characteristics. The cones are treated with a moisture-resistant finish to ensure their longevity in door installations. The woofers are driven by a large 1-inch (25 mm) fiberglass voice coil former. The large diameter of the coil contributes to the 40-watt continuous, 80-watt maximum power ratings for the drivers. Lastly, they all use a rubber surround instead of foam for an additional improvement in longevity.

The tweeters used in the coaxial and component set solutions once again feature neodymium magnets for excellent efficiency. The diaphragms are made of Audison’s Tetolon silk and cotton dome material to optimize rigidity and damping characteristics to prevent distortion. In the APBMW K4E and K4M component sets, the tweeters have a diameter of 29 mm. Most tweeters in this class, including these vehicles’ stock tweeters, are only 25 mm in size. The larger diameter allows for a nice, low resonant frequency and lower crossover points. The large diaphragm size also improves efficiency.

The component sets include the APBMW CXTM 1 passive filter networks for the tweeters. These filters include 0 and -3 dB output options, and OE-quality connectors are included for wiring. Angled mounting cups for the tweeters are included for rear parcel shelf installations. In the APBMW X4M and X4E coaxial speaker solutions, the tweeters use the same materials but have a diameter of 24 mm. Audison also offers the APBMW A4E accessory kit to allow for the unique installation applications of the F15 chassis X5, F16 chassis X6 and the G30 and G31 chassis 5-series sedans and wagons.

Audison BMW
The Audison APBMW K4E is a 4-inch midrange and 29 mm tweeter set designed specifically to bolt into your BMW or Mini with no modifications.

The Prima-Series APBMW X4E is a 4-inch coaxial driver with a neodymium magnet on the 4-inch midrange and a 24 mm Tetolon tweeter.

Prima Subwoofer for BMW and Mini Cars and SUVs

The APBMW S8-2 and APBMW S8-4 are 8-inch (200 mm) subwoofer solutions that are a direct drop-in replacement for the under-seat subwoofers found in BMW and Mini vehicles. These subwoofers feature graphite fiber-reinforced baskets with top-mounted neodymium motor structures. A pair of 5-millimeter polyurethane mounting gaskets are included to ensure a perfect seal with the factory enclosure. A 38 mm (1.5-inch) voice coil provides reliable performance at the speaker’s 150-watt power handling rating. The woofers’ cones are made from pressed pulp, and they use a rubber surround for longevity. A fabric cover over the face of the woofer cone prevents coins and rogue french fries from entering the speaker and causing buzzes or rattles. The woofers feature an Xmax specification of 7 mm in each direction for impressive output from the limited space and shallow mounting requirements.

The Audison engineers put some careful planning into the 2- and 4-ohm models. The 4-ohm S8-4 is slightly less sensitive than the 2-ohm model but offers a 40 Hz resonant frequency instead of 45, so it plays deeper. When the 4-ohm woofer is bridged onto a pair of channels from a Prima amplifier, the additional power allows it to play as loudly as the 2-ohm driver. If you plan a system that will use a larger subwoofer (10- or 12-inch) in the trunk or cargo area, the under-seat woofers function well as midbass drivers.

With an Xmax specification of 7 mm, the APBMW S8-4 subwoofer delivers great bass output that bolts right into your BMW or Mini.

Visit Your Local Authorized Audison Dealer To Upgrade Your BMW Audio System

If your BMW or Mini sound system doesn’t give you goosebumps when you listen to it, drop by your local authorized Audison Retailer and ask about upgrading the speakers. The Product Specialist can design a solution that works with the existing source unit and amplifier or put together a Sound Pack solution with a dedicated DSP-equipped amplifier like the AP 8.9 bit. They can even create a bespoke solution for cars and SUVs that are equipped with fiber-optic MOST amplifiers.
