Lossy Compression - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/lossy-compression
Khalid Sayood, in Introduction to Data Compression (Fifth Edition), 2018. 1.1.2 Lossy Compression. Lossy compression techniques involve some loss of information, and data that have been compressed using lossy techniques generally cannot be recovered or reconstructed exactly. In return for accepting this distortion in the reconstruction, we can generally obtain …

Lossy Data Compression: MP3. The Concept. The Algorithm. MP3: An Overview. The MPEG audio standard is a high-complexity, high-compression, and high audio quality algorithm. The Motion Pictures Experts Group (MPEG), a group that works on standards for both audio and video systems, saw the benefits of the digital representation of audio data.

What Data Compression Does To Your Music
https://www.soundonsound.com/techniques/what-data-compression-does-your-music
Common lossy audio compression formats work at sample rates between 8 and 48 kHz — and remember that the standard audio CD sample rate is 44.1kHz, which gives a frequency response up to 20kHz. Audio that's encoded at 22.05kHz has a high-frequency limit of about 10kHz, and audio encoded at 8kHz only up to about 4kHz.

https://audiouniversityonline.com/lossy-vs-lossless-audio/
Any data compression format that discards data is considered a lossy format. The most common lossy audio file formats are .MP3 and .AAC. In an attempt to make the file size smaller, the audio is processed through a compression codec.

https://www.maketecheasier.com/audio-compression-and-lossless-audio/
Lossy compression is a one-way technique that throws away non-critical data to save space. These techniques are the most common methods used to compress audio files, showing up in MP3, AAC and WMA files alike. There are two places that lossy codecs look to save bits: bit rate and psychoacoustics.
