Sample Rate

Enable Feature

📘

If you are using the Sample Rate feature Encoding is also required.

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).
