This is what I included in the .c file:

#include <stdio.h>
#include <Carbon/Carbon.h>
#include <AudioToolbox/AudioToolbox.h>
#include <CoreAudio/CoreAudio.h>


And this is how I compiled it:

gcc -framework Carbon -framework AudioToolbox -framework CoreAudio myApp.c -o myApp


I might have made some mistake, though.

Did you include the CoreAudio.framework in your project?

So I have just recently started to look into core audio and have started to
experiment with a simple file format converter.
In one of AudioFileCreate´s fields an AudioStreamBasicDescription seems to
be called for.


I keep getting a compile error saying: AudioStreamBasicDescription and my
own struct of this type is undeclared.
It should be included in CoreAudio.h right?


This is what I did:

      AudioStreamBasicDescripton OutFormat;

      OutFormat.mSampleRate            = 44100;
      OutFormat.mFormatID                  = kAudioFormatLinearPCM;
      OutFormat.mFormarFlags            =
kLinearPCMFormatFlagIsSignedInteger;
      OutFormat.mBytesPerPacket       = 2;
      OutFormat.mFramesPerPacket   = 1;
      OutFormat.mBytesPerFrame        = 2;
      OutFormat.mChannelsPerFrame = 1;
      OutFormat.mBitsPerChannel        = 16;
