Crate audio_codec_algorithms

This crate contains simple audio codecs. Supported codecs are:

• G.711 A-law
• G.711 μ-law
• IMA ADPCM

Structs

AdpcmImaState

State values for the IMA ADPCM encoder and decoder.

Enums

Error

Error values.

Functions

decode_adpcm_ima

Decodes a 4-bit encoded IMA ADPCM value to a linear 16-bit signed integer sample value.

decode_adpcm_ima_ima4

Decodes an AIFF-C / QT “ima4” compressed block to 16-bit signed integer samples.

decode_adpcm_ima_ms

Decodes WAV / MS IMA ADPCM (wav format 0x0011) compressed block to 16-bit signed integer samples.

decode_alaw

Decodes a 8-bit encoded G.711 A-law value to a linear 16-bit signed integer sample value.

decode_ulaw
