I’m a beginning developer who has done a bit of audio work. I was just wondering what is the approach to starting to work with audio on the iphone platform.

I envision this as somehow getting a vector of numbers which represent the samples in an audio track. Then programmatically running algorithms on that vector (or array) that would act as filters or other DSP functions.

I could be totally off in my thinking, but I guess that is the point of my question. How do I get to this point where I’m able to start coding the audio on a very low level in the iphone environment.

Thanks!

    The aurioTouch example from the Apple site may be of use. The example analysis the audio data and displays the frequency domain of it.

    From the example;

    The code uses: the AU Remote IO audio
    unit to get the audio input and copy
    it to the output the UI presents: –
    Oscilloscope view of the audio – time
    domain – frequency domain – Scrolling
    sonogram of the audio – Mute button to
    turn on/off the play through
