DTMF Detection?

[Intel_C_Intel]

Hi,

Is there a module in IPP which performs detection of DTMF events in an audio buffer? I can't tell from the docs, sorry. I presumed that the USC Tone Detector API exposes this functionality, but it seems to support only /ANS tones, with which I'm unfamiliar. Can anyone shed any light?

Thanks

Hello Andrew

Yes, USC Tone sample detects only /ANS echo cancellerdisabling tone (see RFC2833).In nearest future IPP plan to support DTMF as well.

Thanks for the quick response Vyacheslav.

Do you have an expected date for DTMF detection functionality?

Andrew,

there is no a firm date for releasing such an IPP sample. Most probably it may happen sometime in the next year. Actually all building blocks for that already in IPP, so you may try to develop such sample by yourself.

Vladimir

Hi Vladimir, is DTMF tone detection available yet within IPP? I attended a conference recently where I was told it is, but I just tried to find it within IPP (including beta 6) and can't find it.
