Enum Constant Summary

Enum Constants
Enum Constant and Description
`AUDIO_ENCODING_AMR` Adaptive Multi-Rate Narrowband codec.
`AUDIO_ENCODING_AMR_WB` Adaptive Multi-Rate Wideband codec.
`AUDIO_ENCODING_FLAC` [`FLAC`](https://xiph.org/flac/documentation.html) (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`.
`AUDIO_ENCODING_LINEAR_16` Uncompressed 16-bit signed little-endian samples (Linear PCM).
`AUDIO_ENCODING_MULAW` 8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.
`AUDIO_ENCODING_OGG_OPUS` Opus encoded audio frames in Ogg container ([OggOpus](https://wiki.xiph.org/OggOpus)).
`AUDIO_ENCODING_SPEEX_WITH_HEADER_BYTE` Although the use of lossy encodings is not recommended, if a very low bitrate encoding is required, `OGG_OPUS` is highly preferred over Speex encoding.
`AUDIO_ENCODING_UNSPECIFIED` Not specified.

Enum Constant Detail

AUDIO_ENCODING_UNSPECIFIED

public static final AudioEncoding AUDIO_ENCODING_UNSPECIFIED

 Not specified.

AUDIO_ENCODING_UNSPECIFIED = 0;

AUDIO_ENCODING_LINEAR_16

public static final AudioEncoding AUDIO_ENCODING_LINEAR_16

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

AUDIO_ENCODING_LINEAR_16 = 1;

AUDIO_ENCODING_FLAC

public static final AudioEncoding AUDIO_ENCODING_FLAC

 [`FLAC`](https://xiph.org/flac/documentation.html) (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.

AUDIO_ENCODING_FLAC = 2;

AUDIO_ENCODING_MULAW

public static final AudioEncoding AUDIO_ENCODING_MULAW

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

AUDIO_ENCODING_MULAW = 3;

AUDIO_ENCODING_AMR

public static final AudioEncoding AUDIO_ENCODING_AMR

 Adaptive Multi-Rate Narrowband codec. `sample_rate_hertz` must be 8000.

AUDIO_ENCODING_AMR = 4;

AUDIO_ENCODING_AMR_WB

public static final AudioEncoding AUDIO_ENCODING_AMR_WB

 Adaptive Multi-Rate Wideband codec. `sample_rate_hertz` must be 16000.

AUDIO_ENCODING_AMR_WB = 5;

AUDIO_ENCODING_OGG_OPUS

public static final AudioEncoding AUDIO_ENCODING_OGG_OPUS

 Opus encoded audio frames in Ogg container
 ([OggOpus](https://wiki.xiph.org/OggOpus)).
 `sample_rate_hertz` must be 16000.

AUDIO_ENCODING_OGG_OPUS = 6;

AUDIO_ENCODING_SPEEX_WITH_HEADER_BYTE

public static final AudioEncoding AUDIO_ENCODING_SPEEX_WITH_HEADER_BYTE

 Although the use of lossy encodings is not recommended, if a very low
 bitrate encoding is required, `OGG_OPUS` is highly preferred over
 Speex encoding. The [Speex](https://speex.org/) encoding supported by
 Dialogflow API has a header byte in each block, as in MIME type
 `audio/x-speex-with-header-byte`.
 It is a variant of the RTP Speex encoding defined in
 [RFC 5574](https://tools.ietf.org/html/rfc5574).
 The stream is a sequence of blocks, one block per RTP packet. Each block
 starts with a byte containing the length of the block, in bytes, followed
 by one or more frames of Speex data, padded to an integral number of
 bytes (octets) as specified in RFC 5574. In other words, each RTP header
 is replaced with a single byte containing the block length. Only Speex
 wideband is supported. `sample_rate_hertz` must be 16000.

AUDIO_ENCODING_SPEEX_WITH_HEADER_BYTE = 7;
