I'm evaluating IPP 5.1 and decoded a raw G729A stream into a PCM file. when playing this .wav file the sound is metallic.
Any ideas what the issue could be, I've implemented the "example" from the usc_interface.htm page and looked at this forum . I checked the G729 incoming stream for VAD frames of 2 bytes but there are non in, so that is not the issue.
any advise is appreciated,
The only difference with the eample code is
for(i=0; i
}
I'm using a "char" casting , in the example it is an unsigned char, but the struct is not allowing this.

Dear Dirk
This is Ying, IPP support. I receive your question from Vlad.
As I knew, some customers have problem when build our G729 sample in their applications( require NO_SCRATCH_MEMORY_USED defined during build) in IPP5.1. We modify the sample since IPP 5.2 beta. So you may try rebuild your example with the speech sample associated with IPP 5.2 beta,

Or could you please provide your example code and test file to us so we can investigate the problem further? You can submit your issue and attach the files on <
Regards,
Ying

Sorry for the offtopic:
I have the same problem with the Premier Support. I've been trying to explain this problem for more than a month. But I still cannot get the required information.

hello ying,
I tried your suggestions (scratch mem) but no luck. I also send the raw stream to ligoban to test with his decoder, but he also has the metallic sound (the same raw data is working perfect with va_decoder)
I'm now downloading the 5.2 and keep you up to date.
any news yet on how to post the raw data somewhere? (not on premier site since I don't have access)
thanks
Dirk
