Declared in ZegoExpressDefines.h

Properties

ZegoAudioCodecIDDefault

ZegoAudioCodecIDDefault=(0)

Default, determined by the [scenario] when calling [createEngine].

ZegoAudioCodecIDNormal

ZegoAudioCodecIDNormal=(1)

Can be used for RTC and CDN streaming; bitrate range from 10kbps to 128kbps; supports stereo; latency is around 500ms. Server cloud transcoding is required when communicating with the Web SDK, and it is not required when relaying to CDN.

ZegoAudioCodecIDNormal2

ZegoAudioCodecIDNormal2=(2)

Can be used for RTC and CDN streaming; good compatibility; bitrate range from 16kbps to 192kbps; supports stereo; latency is around 350ms; the sound quality is worse than [Normal] in the same (low) bitrate. Server cloud transcoding is required when communicating with the Web SDK, and it is not required when relaying to CDN.

ZegoAudioCodecIDNormal3

ZegoAudioCodecIDNormal3=(3)

Not recommended; if you need to use it, please contact ZEGO technical support. Can only be used for RTC streaming.

ZegoAudioCodecIDLow

ZegoAudioCodecIDLow=(4)

Not recommended; if you need to use it, please contact ZEGO technical support. Can only be used for RTC streaming.

ZegoAudioCodecIDLow2

ZegoAudioCodecIDLow2=(5)

Not recommended; if you need to use it, please contact ZEGO technical support. Can only be used for RTC streaming; maximum bitrate is 16kbps.

ZegoAudioCodecIDLow3

ZegoAudioCodecIDLow3=(6)

Can only be used for RTC streaming; bitrate range from 6kbps to 192kbps; supports stereo; latency is around 200ms; Under the same bitrate (low bitrate), the sound quality is significantly better than [Normal] and [Normal2]; low CPU overhead. Server cloud transcoding is not required when communicating with the Web SDK, and it is required when relaying to CDN.
