We’ve been hearing a lot about lossless audio lately. Apple Music says it has it. So does Amazon Music. Tidal and Qobuz have it too, but Spotify doesn’t. (Yet. Or still.) Is lossless audio a big deal?

Suppose on the face value their claims are true about the compression ratio vs fidelity loss - "CD quality audio at 1/10th the current standard data size". That's an order of magnitude improvement. So ...

Last week, Meta announced an AI-powered audio compression method called "EnCodec" that can reportedly compress audio 10 times smaller than the MP3 format at 64kbps with no loss in quality. Meta says ...

There things stood until the age of the personal computer and the internet. A three-minute track on a CD (which is the length of a typical pop song) occupies 31,752,000 bytes, or just over 30MB.

The goal of digital compression algorithms is to produce a digital representation of an audio signal which, when decoded and reproduced, sounds the same as the original signal, while using a minimum ...

Encoding digital audio data to take up less storage space and transmission bandwidth. Audio compression typically uses lossy methods, which eliminate bits that are not restored at the other end. ADPCM ...

Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...
