Deepgram’s Encoding feature allows you to you to specify the expected encoding of your submitted audio. This feature is only required when raw, headerless audio packets are sent to the streaming service.
Some examples of use cases for Encoding include:
- Customers who need to stream raw audio data.
To enable Encoding, when you call Deepgram’s API, add an
encoding parameter in the query string and set it to the audio coding algorithm of your submitted audio:
Deepgram supports the following audio coding algorithms:
linear16: 16-bit, little endian, signed PCM WAV data
flac: FLAC-encoded data
mulaw: mu-law encoded WAV data
amr-nb: Adaptive Multi-rate (AMR) narrowband codec. When using this option, you must also specify
amr-wb: Adaptive Multi-rate (AMR) wideband codec. When using this option, you must also specify
opus: Ogg Opus
