RBPi 2 Audio recording with frequency limits?

[vicvaldoh]

Whats up guys-

I have a quick question pertaining to execution.

To preface, I am a CS student and I have joined a project in which I must use a RBPi2 to record audio. I am new to Raspberry Pi, but I understand that this is completely possible and quite easy?

My question concerns the materials that I must use (mic, sound card, programs, APIs, etc.) in order to do this. In addition, some potentially useful information is that I also must set a range in frequency in which the input can be recorded, i.e. if it is not in the range (x,y), then the frequency will not be recorded).

I understand this may be the incorrect thread, etc. and that this is a big no no, but I am at a loss and I must find information somewhere. Thank you all for any help you may be able to give me.

Best.

The Pi does not have an audio input.

Easy to add though, check out one of those cheap C-Media based USB Audio devices.

Then it is just a standard Linux audio input device, so you can find out about your additional questions in a much more general search.
