You’ll soon be able to listen to lossless audio through wireless headphones, after semiconductor company Qualcomm announced it was making the technology available for Bluetooth.
Lossless audio files are compressed (made smaller) without affecting the sound. This contrasts with ‘lossy’ audio, which discards information during the compression process, reducing sound quality.
Bluetooth exacerbates this by applying its own lossy compression. That’s why you typically need wired speakers or headphones to listen to lossless audio. Qualcomm said that until now Bluetooth has unavoidably degraded the audio signal.
However, Qualcomm’s aptX Lossless technology, which is part of its Snapdragon Sound program, can transmit “mathematically bit-for-bit exact” audio at CD quality.
Lossless audio’s appeal is growing, aided by leading audio-streaming services that have started offering it. It’s now available through Deezer, Tidal, Amazon…
