to use IPP6.1 to decode siren14?

[yida_123]

i used ipp6.1 to decode siren14. the bitrate is 48kbps .

the attachments is siren14 packet.

IP :192.168.100.103 to 192.168.100.101 has the audio.

RTP siren14 pt = 99 .

i have solve this problem more than one weeks ! who can help me ?

Hi Chao

Thanks for your reply again.

this time i use ipp6.1 to decode siren14. there is no sound

the ipp6.1 G.722.1 readme.html has describ

USC G722.1 codec parameters:

Codec name: IPP_G722.1

Compression algorithm: Modulated linear transform (MLT) based coding

Linkage: USC_G722_Fxns

Sampling: 16bit linear 16000 Hz and 32000 Hz

Frame: 20ms

Bitrates: 16000 bps (320 bpf), 24000 bps (480 bpf) and 32000 bps (640 bpf)

Voice Activity Detection: VAD not supported

Packet Loss Concealment: PLC not supported

Frame types (value): Good (0), Bad (1)

Standard: ITU-T G.722.1, Annex C

but my used siren14 is 48kbps is that means , ipp6.1 cann't decode thesiren14?

thanks

Hi

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.

Hi Vyacheslav:

Thanks for your reply!

You means that ipp6.1 cann't decode Siren14(24, 32 and 48 kbps bitrates for 32 Khz audio), and in the nearest future didn't plan to do that. Is that right?

Another IPP6.1 can Decoder siren71624 and 32 kbps bitrates for 16 Khz audio). Is that right?

Hi,

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.
