8-bit samples that compand 14-bit audio samples using G.711 PCMU/A-law.
Audio content returned as ALAW also contains a WAV header.
Linear16
Uncompressed 16-bit signed little-endian samples (Linear PCM).
Audio content returned as LINEAR16 also contains a WAV header.
Mp3
MP3 audio at 32kbps.
Mulaw
8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.
Audio content returned as MULAW also contains a WAV header.
OggOpus
Opus encoded audio wrapped in an ogg container. The result will be a
file which can be played natively on Android, and in browsers (at least
Chrome and Firefox). The quality of the encoding is considerably higher
than MP3 while using approximately the same bitrate.
Unspecified
Not specified. Will return result [google.rpc.Code.INVALID_ARGUMENT][].
