Criteria for Speech Coding 1. Bit rate, or amount of compression — phonemic bit rate of speech: approx. 50 bits/sec (bps) — cognitive content bit rate of speech: approx. 400 bps — how close can we get to this? 2. Intelligibility 3. "Naturalness“, quality 4. Processing effort 5. Complexity of implementation 6.

What is audio compression? Whether you’re mixing a music track or recording a podcast, audio compression is a useful tool for sound engineers who want to smooth out the sound of instruments, vocals and more.From an acoustic guitar with too much pick noise to a piano that doesn’t have any punch to it, an audio compressor has the power to decrease the dynamic …

https://eeweb.engineering.nyu.edu/~yao/EE3414/MML_exp3_speech_compression.pdf
I Introduction A key technology that enables distributing speech and audio signals without mass storage media or transmission bandwidth is compression, also known as coding. It reduces the amount of data needed to transmit and store digitally sampled audio either during analog-to-digital conversion step or after the raw file is stored digitally.
Audio Coding: An Introduction to Data Compression – …
https://www.eetimes.com/audio-coding-an-introduction-to-data-compression-part-1/
The various speech coding algorithms we studied in the previous chapter rely heavily on the speech production model to identify structures in the speech signal that can be used for compression. Audio compression systems have taken, in some sense, the opposite tack. Unlike speech signals, audio signals can be generated using a large number of different …
