US6049765A - Silence compression for recorded voice ...
https://patents.google.com/patent/US6049765A/en
A silence compression system that improves data compression in a digital speech storage device, such as a digital telephone answering machine, without undue clipping of voice signals. Instead of employing only real-time compression, the inventive silence system analyzes and compresses or re-compresses digital speech samples stored previously, when the voice …
The Complete Guide to Audio Compression – Icon …
https://iconcollective.edu/audio-compression/
Audio compression reduces the dynamic range of an audio signal. Dynamic range is the difference between the loudest and quietest parts of a waveform. Compression reduces this range by attenuating the louder signals and boosting the quieter signals. As a result, the loudest and softest parts are closer in volume, creating a more balanced sound. ...
Audio Compression - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/audio-compression
Conventionally, voice compression aims at removing the silence and music compression at finding an efficient way to reconstruct music to play to the end user. Today, almost every stage between the source sound and the reconstructed sound involves a data compression process of one type or another. ... Wideband audio compression is generally ...

Lossy audio compression such as MP3 is appropriate for situations in which it is necessary to specify the best perceived audio quality at a specific, guaranteed bit rate. Lossless compression, ... silence) would compress down to an integer representing the …
Drawbacks of conventional audio compression methods:
https://www.ques10.com/p/7308/discuss-the-drawbacks-of-different-conventional--1/
Audio files containing long periods of low-volume sound will respond to silence compression better than other files with high-volume sound. This method requires a user-controlled parameter that specifies the largest sample that should be suppressed.
