AudioCodec enum

Audio codecs supported by PortSIP SDK.

Each codec has a corresponding integer value that matches the AUDIOCODEC_TYPE enum from the native PortSIP SDK.

Codecs are categorized by bandwidth:

Narrowband (8 kHz): PCMU, PCMA, GSM, G.723, G.729, iLBC, Speex, AMR
Wideband (16 kHz): G.722, Speex WB, ISAC WB, AMR-WB, OPUS
Super-wideband (32 kHz): ISAC SWB

Example usage:

await portsip.setAudioCodecs(audioCodecs: [
  AudioCodec.opus,
  AudioCodec.pcmu,
  AudioCodec.pcma,
]);
