The ALAW file extension is a data format associated to A-Law Compressed Sound. 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 ...

A-Law Compressed Sound Format

https://www.loc.gov/preservation/digital/formats/fdd/fdd000038.shtml

Format Description for A-Law -- Standard companding algorithm used in European digital communications systems (telephones, for the most part) to optimize the dynamic range of an analog signal (generally a voice) for digitizing, i.e., to compress 16 bit LPCM (Linear Pulse Code Modulated) data down to 8 bits of logarithmic data.

need to establish voice communication you can configure the device to perform audio coder transcoding between the inbound and outbound legs to enable media flow between them. For instance, if the (A) inbound leg offers a G.729 coder, but the (B) outbound leg only supports G.711 ulaw the device can be configured to transcode the G.729 to G.711.

A-law algorithm - Wikipedia

https://en.wikipedia.org/wiki/A-law_algorithm

An A-law algorithm is a standard companding algorithm, used in European 8-bit PCM digital communications systems to optimize, i.e. modify, the dynamic range of an analog signal for digitizing. It is one of two versions of the G.711 standard from ITU-T, the other version being the similar μ-law, used in North America and Japan.. For a given input , the equation for A-law …

audio - Decode G711(PCM u-law) - Stack Overflow

https://stackoverflow.com/questions/3251782/decode-g711pcm-u-law

The audio is encoded in G711 (PCM ulaw). Do I need to decode the PCM audio data to a raw audio data before I could pass it to the audio engine to play? If so, is there some sample code on how to decode it? I am confused as somehow I believe PCM is already RAW. Could I just feed it directly to the audio engine on Android for example?
