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).
