The iLBC audio codec will be removed from WebRTC.
The codec is not used in Chrome (`RTCRtpSender.getCapabilities('audio').codecs` does not mention it) and the cost of maintaining and keeping the code secure is hard to justify.
We suggest that any current users of iLBC should migrate their applications to Opus, which is a full-band codec with superior audio quality. Alternatively, the G.722 codec is still available in Chrome as a low-complexity wideband option.
Sincerely,
The WebRTC team
