A-Law Compressed Sound Format
https://www.loc.gov/preservation/digital/formats/fdd/fdd000038.shtml
From Archived Voice Codecs FAQ from Nuvoton:"µ-law and A-law are audio compression schemes defined by ITU-T G.711 that compress 16 bit linear data down to 8 bits of logarithmic data. The encoding process (referred to logarithmic companding) breaks the linear data into segments with each progressively higher segment doubling in size.

ALAW files and A-Law Compressed Sound were released in 1972. These files represent audio compression scheme common in voice only applications and are mostly used in European systems. Slightly similar to u-Law compression format, it compresses original 16-bit audio down to 8 bits (for a 2:1 compression ratio) with a dynamic range of about 13-bits.The compression …

Table 4, m-Law Decoding Summary There is a wide array of audio transmission systems that employ A-law and/or µ-law companding for data rate reduction with good audio quality. The compression achieved by both A-law and µ-law coding is the result of utilizing the logarithmic characteristics of the human auditory system, where fewer bits of

The G711 codec comes in two different compression algorithms: μ-law and A-law. A-law is the standard compression for international circuits. The G711 A-law compression algorithm is used in Europe, and almost all over the world. The A-law is logarithmic, and lighter for the computer to process. The G711 A-law encodes a 13 bit signed linear PCM ...

A-law, μ-law and CVSD digital audio CODEC in PCM interface. I am trying to use the BT stack library from bluekitchen to implement a bluetooth device that transfers audio to a bluetooth headset using the HSP profile. However, HSP profile uses CVSD modulation for the audio signals. If I am getting audio signals from an external CODEC that gives me PCM data …

Apple Lossless Audio Codec, or ALAC, is another lossless audio codec that, as the name suggest, works primarily with Apple devices. Just like the FLAC, its files are compressed to a much smaller size without affecting its quality. Since these files are obviously larger than lossy audio files, they take longer to download.
