Re: need help

Here it is:
I have to make a hardware project within 2 months .it is about dsp based adaptive noise cancellation from audio acquisition/playback.
I have to first acquire audio (voice/speech) using microphone ,feed it in DSP processor and then do some adaptive filtering and then play it back.
i was hoping if i could get some help in acqiring voice and at the same time playing it back, some kind of real time acquisition of speech.The dsp processor accepts signal as analog form so feeding the speech and the ambient noise directly was one of the alternative.But my guide stressed upon a hardware ckt to acquire audio thro Microphone and at the same time another microphone can be used to record ambient noise and these two signals will then be used while doing adaptive filtering.


So i hope if u can give me some directions which would be helpful in making audio acquisition system using microphone.
like a recorder and playback(for outputting the audio) in music system.
Thanks
