Your next set of earbuds could make the most of Amazon Music HD or Apple Music lossless

2021 has been a big year for lossless music now that Apple has gone in on the higher-quality streaming and Amazon is no longer charging an added premium for it. But one of the main challenges confronting lossless audio is how to play it wirelessly (at full fidelity) on wireless headphones and earbuds. Qualcomm thinks it has found a solution with the new aptX Lossless, which is part of the company’s Snapdragon Sound program announced earlier this year.

With aptX Lossless (which is technically an extension of aptX Adaptive), Qualcomm says it’ll be able to stream CD-quality, 16-bit / 44.1kHz lossless audio over Bluetooth. The first devices to feature the new technology are expected to be available in early 2022. Snapdragon Sound leans on the whole hardware chain for optimal performance — so both your Android mobile phone and your earbuds or headphones will need to support it.

You can now stream CD-quality audio losslessly over Bluetooth, if you have the right kit
... ....
Qualcomm told What Hi-Fi? that CD-quality (16-bit/44.1kHz) audio transmission is achieved between 1.1Mbps and 1.2Mbps (1,100 and 1,200kbps) with aptX Lossless. As a rough reference, aptX Adaptive's maximum bitrate is 420kbps, (the older and less efficient) aptX HD can stream at 576kbps, and LDAC's is 990kbps. A CD audio file is 1,411kbps so you're always losing something here, though these
claimed aptX Lossless figures are very close. Qualcomm says that 'no data is lost when audio is encoded and decoded with aptX Lossless'.

Lossless vs. Hi-Res Audio: What's the Difference?​


Lossless isn't necessarily HRA and vice versa




Lossless Audio: What is it?

In simple terms, Lossless Audio (FLAC, ALAC) refers to an audio file format that can store the original quality of the audio without any loss. When an audio file is compressed, the file size is reduced, but there is a compromise in the sound quality. Lossless Audio, however, compresses the file size while retaining the audio quality. This makes it an ideal format for audiophiles who want to enjoy high-quality music without taking up too much storage space.

High-Res Audio: What is it?

High-Res Audio (DSD, MQA, FLAC, ALAC) is an audio format that provides higher quality audio than traditional CD-quality audio. It offers a much higher bitrate and sampling frequency than standard audio, which means it can capture more sounds, giving a more comprehensive and enjoyable listening experience. Additionally, it can capture a wider frequency range, which reproduces sounds that fall outside of the audible range.


So, what’s the difference between Lossless Audio and High-Res Audio?

While both Lossless Audio and High-Res Audio formats strive to provide the best audio quality, they completely differ in their approach. Lossless Audio achieves its high fidelity by compressing the file size while maintaining the audio quality. On the other hand, High-Res Audio increases the bitrate and sampling frequency to capture every little detail in the audio, making the music sound more realistic.

Another significant difference between these two formats is the playback device. Lossless audio files are compatible with almost all audio devices, including smartphones, laptops, and home audio systems. High-Res Audio files, on the other hand, require special equipment to play at their best quality, such as dedicated high-res audio players, high-end smartphones, and high-quality headphones.


Which one should you choose?

Choosing between Lossless Audio and High-Res Audio comes down to several factors such as storage space, audio quality, and playback equipment. While Lossless Audio offers a high-quality audio experience that is compatible with almost all devices, High-Res Audio provides more detail and realism in the music. However, keep in mind that High-Res Audio files will require more storage space and the right equipment to enjoy the best possible audio quality.

In conclusion, whether you choose Lossless Audio or High-Res Audio, it all comes down to personal preference. If you prioritize compatibility and ease of use, go for Lossless Audio. But if you are an audiophile looking for the most realistic and detailed audio experience, then High-Res Audio is the way to go.

Is lossless audio worth it?​



When would you use lossless audio format?​

  • Professional audio production: In the music industry, lossless audio formats are often used for recording, mixing, and mastering tracks, as they preserve the original audio information and allow for a higher-quality end product.
  • Archiving: Lossless audio formats are also commonly used for archiving purposes, as they allow for the original audio to be entirely preserved without any loss in quality.
  • Audiophile listening: Many audiophiles and music enthusiasts prefer lossless audio formats for listening to music, as they believe that the superior sound quality is worth the larger file size.
  • High-quality playback: Lossless audio formats are also often used in situations where the audio is being played back on high-quality audio systems, such as home theater systems or high-end headphones, as the superior sound quality can be more easily noticed on these systems.
In conclusion, lossless audio is a digital format that preserves all original audio information, resulting in a high-quality audio file, just at the cost of file size.
