The algorithm used in a lossy audio format compresses sound data in a way that discards some information. This signal loss means that the encoded audio isn't identical to the original. The lossy audio produces a lower quality sound and has a smaller file size.

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, which includes formats such as MP3 and AAC that you’re very familiar with, is a type of compression in which some data from the original music is removed during the compression process. When...

On the other hand, JPEG is considered a lossy format because some data is lost in the compression process. However, RAW and JPEG aren’t the only lossless and lossy formats. Below are some common file formats for images, audio, and video. Images: RAW, BMP, and PNG are all lossless image formats. JPEG and GIF are lossy image formats.

The lossy formats listed are examples of what we call perceptual audio encoding formats, which exploit the psychoacoustics of human hearing: assumptions are made about what we might hear and what we might not in different contexts, in order to determine which elements of data can be 'lost'. Simply put, lossy formats always exhibit some quality loss, because the audio content …
Lossy Data Compression
https://cs.stanford.edu/people/eroberts/courses/soco/projects/data-compression/lossy/index.htm
Lossy compression techniques attempt to eliminate unnecessary or redundant information, focusing more on saving space over preserving the accuracy of the data. Ideally, the loss is either minimal or undetectable by human observations. Lossy compression techniques are used for pictures and music files that can be trimmed at the edges.
Lossy Definition - Tech Terms

Lossy file compression results in lost data and quality from the original version. Lossy compression is typically associated with image files, such as JPEGs, but can also be used for audio files, like MP3s or AAC files. The "lossyness" of an image file may show up as jagged edges or pixelated areas. In audio files, the lossyness may produce a watery sound or reduce the …

Compression quality When we use a lossless compression algorithms, we can always reconstruct 100% of the original data. With lossy compression algorithms, we're losing some % of the original data; maybe 5%, maybe 10%, maybe 70%. How much do we lose? We can decide that based on our use case for the data.
What is 'lossy' audio? - Quora
https://www.quora.com/What-is-lossy-audio
Lossy audio just means that the audio has been compressed into a format which doesn’t retain all the audio information of the original file. Certain frequencies which are less important to be heard by the average listener are simply removed in order to reduce file size without making the audio sound too bad.
