Apple Music Audio Quality in Your Tesla Compared to Spotify and Tidal

A look at Apple Music's audio quality

MacRumors/Twitter

Apple Music may be available in Tesla’s new holiday update, but don’t expect the lossless audio quality that Apple Music subscribers enjoy… at least not yet.

Tesla owner and software developer Dan Burkland recently performed some tests on the audio quality that Tesla’s in-car streaming services TIDAL, Spotify, and now Apple Music stream at in the vehicle.

Burkland tested TIDAL previously on a different Tesla software version, but with Tesla’s ever-changing software and the rollout of the holiday update, he chose to run the tests again.

Setup and Songs Used to Test

He connected his Model Y to his home's WiFi network and used a DHCP reservation, which allowed him to have the vehicle use a specific IP address. He then installed ntopng on his OPNsense firewall to monitor traffic statistics for the vehicle. After zeroing out the host stats for the Model Y, he tested a total of nine songs, including “Purple Rain” by Prince, “Foreplay” by Boston, and “Kashmir” by Led Zeppelin.

Results

The results of Burkland’s tests concluded that TIDAL still offers the best listening experience. The average bitrate for TIDAL was ~1165 kbps. This isn’t entirely too shocking, as TIDAL has always championed the highest-quality audio streaming experience.

Surprisingly, Spotify’s audio quality came in ahead of Apple Music to nab second place. Burkland’s tests showed Spotify streaming at an average bitrate of ~157 kbps, while Apple Music came in at a subpar ~118 kbps.

Burkland added that he believes Apple Music is limiting bitrate for the in-car app, but a future update to Tesla’s software will hopefully resolve this. If Tesla can enable lossless streaming for Apple Music, it’ll give TIDAL a run for its money in high-fidelity streaming via the in-car app.

Check out some of Dan’s test results below, or for a complete list view his Reddit thread.

Other Tesla Owners Are Running Similar Tests

Reddit user u/OverlyOptimisticNerd ran similar tests with a slightly different configuration. They used an iPhone 14 as a mobile hotspot, Hotspot Monitor Data Usage from Apple’s App Store, and 2019 Model 3 running version 2022.44.25.1.

During their tests, they observed the same pattern across all songs, citing that a bunch of data rolled in at the beginning of the tests and then slowly trickled through. The low data rate for Apple Music appears to align with the company’s HE-AAC codec at 64 kbps.

“It appears to buffer most or even all of the song, then pause between tracks to do it again,” writes u/OverlyOptimisticNerd. “On average, I saw ~2MB per track, with ~1.7MB during the initial burst and ~0.3MB throughout the track. This is consistent with the HE-AAC standard, as most of these songs were a little over 3 minutes in length.”

While Apple Music may come in at the lowest average bitrate of all three services tested, it's important to note that it doesn't necessarily mean it has the lowest quality. Audio quality comes down to a variety of factors, some of which are, the bitrate, whether it's a variable rate, and the efficiency of the audio codec used.

Apple Music's HE-ACC codec is optimized for low-bandwidth applications meaning that it can outperform an ACC-encoded file in lower-bandwidth situations. In the real-world Apple Music in your Tesla should sound very similar to streaming music from Spotify, but not as good as TIDAL's offerings.

Exclusive: Tesla’s AI Assistant Now Uses Vehicle Data for Personalized Responses

Not a Tesla App

As part of Tesla’s App Update 4.42.5, which is now available on both the Android and iOS App Stores, Tesla has rolled out an improved AI Assistant.

If you’re not familiar with Tesla Assist, it’s the company’s AI-powered assistant, which can be found in the Service section of the Tesla app. The assistant was first introduced with app update 4.35.5, and it has slowly improved to help answer the most common Tesla-related questions.

At first, Tesla Assist could answer general support questions like “What is Sentry Mode?” or “Why is my range lower than expected?” It acted as a helpful starting point for answering questions, but the responses weren’t personalized for you or your vehicle. However, with this latest update, that is changing.

Personalized Support

The latest version of Tesla Assist introduces personalized responses. You can specify which vehicle or product your question relates to and ask specific questions about your vehicle. For now, the responses are limited to a few categories, like tire pressure, however, we expect the assistant to have access to more vehicle information in the future.

For now, you can ask questions such as, “What alerts were recently triggered on my vehicle?” or “Is my tire pressure low?”. We’ve also been successful in asking whether a particular accessory, such as a key fob, would work with our vehicle.

Tesla provides these answers based on information in their owner’s manuals, tutorials, and your vehicle’s details and data.

Just like before, Tesla continues to provide links to related articles, such as the Owner’s Manual or the Service Manual, depending on the context.

Future Releases

While the assistant can’t access every detail just yet — how many miles are on my vehicle — it’s already capable of pulling a lot of service-related information. It appears Tesla may be looking to expand this to other areas, with some responses stating, “Based on your vehicle’s data…”

It’s not clear what’s powering this assistant, but it could be some version of Grok, which will soon be available inside of Tesla vehicles.

The AI-based assistant can be found in the Service section of the Tesla app or by going into the main menu and tapping the question mark in the upper-right corner. Let us know if you’ve seen any other interesting responses from Tesla Assist.

Tesla to Build Third Megafactory in Texas With $200M Investment

Not a Tesla App

Tesla has revealed the location of its third Megafactory, following Mega Lathrop and Mega Shanghai. The new facility will be in Brookshire, Texas, covering 1.6 million square feet—twice the combined size of Mega Lathrop and Mega Shanghai.

Tesla has had a lease deal at the Empire West industrial park since at least late 2021, where a third-party company has been managing the shipment of vehicle parts from Giga Texas and Fremont factories service centers across North America.

Mega… Factory?

The name says it all. Tesla’s Gigafactories focus on vehicle production—like Giga Texas, Giga Berlin, and Giga Shanghai—while Megafactories are dedicated to Tesla’s energy products.

Tesla Energy is expanding rapidly, with executives suggesting it could soon become one of the company’s largest revenue streams as demand continues to outpace supply.

Mega Brookshire will manufacture Megapacks and Powerwalls, Tesla’s primary stationary energy products. Both use LFP batteries, meaning their production won’t impact Tesla’s vehicle output, as most of the company’s cars rely on NMC batteries.

Looking at the Numbers

Tesla plans to invest approximately $194 million in upgrades and equipment across the two buildings, with the facility projected to generate between $8 billion and $10 billion in annual revenue.

Of that investment, $44 million will go toward facility improvements, such as parking, electrical upgrades, accessibility, and structural updates. The remaining $150 million will be allocated to Tesla-sourced manufacturing equipment for product production.

Tesla will also be employing approximately 1,500 people in the local community, which will be a considerable economic boost for the local residents.

Mega Brookshire Phase 2

The Megafactory plans also include funding for a distribution facility, with Tesla set to invest $31 million in its purchase and an additional $2 million for equipment and facility upgrades. Given its proximity to Giga Texas, it’s likely that Mega Brookshire’s distribution terminal will support the Tesla Semi.

This marks Tesla’s first factory announcement since Mega Shanghai. While there were initial plans for Giga Mexico, where Tesla initially planned to build their next-gen vehicle, those plans have seemingly been shelved as Giga Texas and Fremont continue to expand.

Although an official timeline for Mega Brookshire’s launch hasn’t been shared, Mega Shanghai is set to begin production soon after breaking ground in May 2024. Based on that timeline, Mega Brookshire could be operational by mid-to-late 2026.
