Lossy Compression - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/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 much higher compression ratios than is possible with lossless compression.
What Is Lossy Audio Compression? - Lifewire
https://www.lifewire.com/what-makes-an-audio-format-lossy-2438561
The word lossy is used in digital audio to describe a type of compression used to store sound data. The algorithm used in a lossy audio format compresses sound data in a way that discards some information. This signal loss means that …

Lossless Compression ofAudio Data
https://www.montana.edu/rmaher/publications/maher_lossless_chapter_2003.pdf
Available techniques for lossless audio compression, orlossless audio packing, generally employ an adaptive waveform predictor with a variable-rate entropy coding of the residual, such as Huffman orGolomb-Ricecoding.
Data Compression - Lossless and Lossy Techniques
https://www.ijaiem.org/Volume5Issue7/IJAIEM-2016-07-27-28.pdf
2.2) Lossy Compression: Lossy Compression is generally used for image, audio, video. In this compression technique, In this compression technique, the compression process ignores some less important data and the exact replica of the original file can’t be retrieved
How Does Audio Compression Work, and What Is …
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.
Lossy Compression - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/mathematics/lossy-compression
Data such as multimedia images, video and audio are more easily compressed by lossy compression techniques because of the way that human visual and hearing systems work. One important motivation for data compression is to allow some efficient transmission of the data via a transmission channel.
