How to use IPP G.722.1

[yida_123]

I know IPP6.0 surport G.722.1,but when i useUSC_G722_Fxns , it is show by gray ,that means ,it cannot use.

what should i do?

I think you might need to clarify tour question... "it is show by gray" is not clear English. I mean gray is a color right? and G.722 is a speech decoder so describing something in this way may not be the best choice of words...

Hi softrite

now i use ipp5.3 init code as follows

UMC::SpeechCodecParams params
m_OnePacketLen = 66;
m_nSampleFrequency = 16000;
m_FrameSizeOut = 160;
params.law = 0;
params.Vad= 0 ;
params.Truncate = 0;
params.Pf = 1;
params.Hpf = 1;
params.bitrate = 24000;
// bitrate = ChangeOrder(bitrate);
// bitrate=bitrate>>8;
m_pFNS = &USC_G722_Fxns ;

is that right

I am using G.729 1 so I could only help with that one... the packet size looks odd to me though... 66 -> 160 is not much of a compression. On G 729 input is 10 bytes for 160 out. Of course G 729 is mathematical encoding not just compression. Maybe one of the Intel experts will bless you with some advice.

Hi,

IPP 6.1 G.722.1supports bitrates 16, 24, 32 kbps for 16KHz audio(Siren7) and 48 kbps for 32 KHz audio (Siren14).
USC G722.1 Encoder produces 40, 60, 80 and 120 bytes per 20ms framerespectively.
Siren14 was not supported in IPP5.3.

Hi Vyacheslav

Thanks for your reply.

i used it in ipp 6.0 ,48 kbps for 32 KHz audio (Siren14). but still wrong .

i'll try ipp6.1.
