It looks like using core audio to record audio is overly complicated. While QTkit is basic and down to earth However. All of the examples I have see integrate video and audio together. Does some one have or know an example of using QTkit for recording audio?

Hi all,

How can you determine the best audio quality in a list of audio files of the same audio clip, with out looking at the audio file's header. The tricky part is that all of the files came from different formats and bit rates and they where all transcoded to the same format and bit rate. How can this be done efficiently?

I'm looking at the aurioTouch sample application for the iPhone SDK. It has a basic spectrum analyzer implemented when you choose the "FFT" option. One of the things the app is lacking is X axis labels (i.e. the frequency labels).
In the aurioTouchAppDelegate.mm file, in the function - (void)drawOscilloscope at line 652, it has the foll...

I've created two wave files using Audacity. Both have 44100hz sample rate, 32-bit float samples, were saved as WAV (Microsoft) 16-bit signed and contain 1s of silence (according to Audacity). The difference is that one file contains one channel, while the other have two (stereo). When reading the one channel file I got frames like this:

The File is not stored in the Ressources but a file on the storage card. Even though neither the load nor the play function of the SoundPool throw any Exception or print anything to the console, the soun...

[sitar play];
So I only change sitar.wav into my .mp3 filename.
