   * Required. Encoding of audio data.

   *   Uncompressed 16-bit signed little-endian samples (Linear PCM).
   * - `flac`
   *   `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`.
   * - `mulaw`
   *   8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.
   * - `amr`
   *   Adaptive Multi-Rate Narrowband codec. `sample_rate_hertz` must be 8000.
   * - `amr-wb`
   *   Adaptive Multi-Rate Wideband codec. `sample_rate_hertz` must be 16000.
   * - `ogg-opus`
   *   Opus encoded audio frames in [Ogg](https://wikipedia.org/wiki/Ogg)
   *   container. `sample_rate_hertz` must be one of 8000, 12000, 16000, 24000,
   *   or 48000.
   * - `mp3`
   *   MP3 audio. Support all standard MP3 bitrates (which range from 32-320
   *   kbps). When using this encoding, `sample_rate_hertz` has to match the
   *   sample rate of the file being used.
