STREAMING

Deepgram’s Sample Rate feature allows you to specify the sample rate of your submitted audio.

The Sample Rate feature is required when the Encoding feature is being used to submit streaming raw audio. It is not read at any other time.

Enable Feature

To enable Sample Rate, when you call Deepgram’s API, add a sample_rate parameter in the query string and set it to the sample rate of your submitted audio.

sample_rate=SAMPLE_RATE_VALUE

When submitting audio encoded with the Adaptive Multi-rate (AMR) codec, you must submit specific Sample Rate values:

  • amr-nb: AMR narrowband codec. When using this option, you must specify sample_rate=8000 (encoding=amr-nb&sample_rate=8000).
  • amr-wb: AMR wideband codec. When using this option, you must also specify sample_rate=16000 (encoding=amr-wb&sample_rate=16000).

For an example of audio streaming, see Getting Started with Streaming Audio.
