The audio data bytes encoded as specified in the request, including the
header for encodings that are wrapped in containers (e.g. MP3, OGG_OPUS).
For LINEAR16 audio, we include the WAV header. Note: as
with all bytes fields, protobuffers use a pure binary representation,
whereas JSON representations use base64.
