Audio encoding is just simply translating audio signals to digital. By nature, audio is analog signal. Your voice is analog, any sound you hear is analog. Now for this signal to be able to transmitted over the internet or any digital medium, it should of course be converted to digital signal. Analog signals are in the form of waveforms, whereas digital signals are in binary form, with bits of 0s …

Encoding digital audio requires five major steps. First, Modified Discrete Cosine Transform (MDCT) converts the signal from time-domain to frequency domain. Filter banks are used to convert an exact number of time samples into frequency samples. Second, the frequency domain is quantized using a psychoacoustic model and then encoded.

The audio signal is then encoded by an ADPCM encoding algorithm and generating G_APM as a result ADPCM encoded bits. Further, the method comprises generating G_QB data bits indicative of an internal value, e.g. a scaling value, of the adaptive quantization part of the ADPCM encoding algorithm.

• Perceptual Audio Encoding is the encoding of audio signals, incorporating psychoacoustic knowledge of the auditory system, in order to reduce the amount of bits necessary to faithfully reproduce the signal. • MPEG-1 Layer III (aka mp3) • MPEG-2 Advanced Audio Coding (AAC)
PCM Audio - COMPLETE GUIDE AND REFERENCE
https://planethifi.com/pcm-audio/
In telephony, a standard audio signal for a single phone call is encoded as 8,000 analog samples/sec, 8 bits each, giving a 64 kbps digital signal known as the DS0 signal. The default signal compression encoding in a DS0 signal is either Ley PCM audio (in North America and Japan) or Ley A PCM audio (In Europe and most of the rest of the world).
The Use of FFT and MDCT in MP3 Audio Compression
https://www.math.utah.edu/~gustafso/s2012/2270/web-projects/Guckert-audio-compression-svd-mdct-MP3.pdf
MP3 Encoding Algorithm The overall algorithm is broken up into 4 main parts. Part 1 divides the audio signal into smaller pieces, these are called frames. An MDCT filter is then performed on the output. Part 2 passes the sample into a 1024-point FFT, and then the psychoacoustic model is applied. Another MDCT filter is performed on the output.
