AudioEncoding(value)Configuration to set up audio encoder. The encoding determines the output audio format that we'd like.
Values:
AUDIO_ENCODING_UNSPECIFIED (0):
Not specified. Will return result
google.rpc.Code.INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT].
LINEAR16 (1):
Uncompressed 16-bit signed little-endian
samples (Linear PCM). Audio content returned as
LINEAR16 also contains a WAV header.
MP3 (2):
MP3 audio at 32kbps.
OGG_OPUS (3):
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.
MULAW (5):
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.
ALAW (6):
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.
