AudioEncoding specifies the encoding of the audio bytes in the encapsulating message.

Used in: asr.RecognitionConfig, tts.SynthesizeSpeechRequest

• ENCODING_UNSPECIFIED = 0

  Not specified.

• LINEAR_PCM = 1

  Uncompressed 16-bit signed little-endian samples (Linear PCM).

• FLAC = 2

  `FLAC` (Free Lossless Audio Codec) is the recommended encoding because it is lossless--therefore recognition is not compromised--and requires only about half the bandwidth of `LINEAR16`. `FLAC` stream encoding supports 16-bit and 24-bit samples, however, not all fields in `STREAMINFO` are supported.

• MULAW = 3

  8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.

• ALAW = 20

  8-bit samples that compand 13-bit audio samples using G.711 PCMU/a-law.
