The USC_G722_Fxnscodec supports24, 32 and 48 kbps bitrates for 32 Khz audio (Siren14), butunfortunately this was not properly documented.This inconsistency inthe G722.1 readmewill be fixed in one of the nearestIPP releases, thank you for the notification.Please note that thoughraw codingfor Siren14 was implemented inthe usc_speech_codec sample, RTP support for Siren14was notyet implemented intheumc_speech_rtp_codec sample and IPP hasno planto do that in the nearest future.

USC_G722_Fxns codec from IPP6.1 supportsboth encode and decodefor Siren7 (16 Khz) and Siren14 (32 Khz).It was only miss in a readme document.Theusc_speech-codec sample supports raw coding forboth. Though, theumc_speech_rtp_codec sample supports RTPonlyfor Siren7, there is no support for RTPSiren14.
