My quick workaround for this is:

in AudioFileWriter.m

  • (id)initWithAudioFileURL:(NSURL *)urlToAudioFile samplingRate:(float)thisSamplingRate numChannels:(UInt32)thisNumChannels

just above the line with CheckEroor(ExtAudioFileCreateWithURL... i added the following code which removes the file if it already exists:

if ([[NSFileManager defaultManager] fileExistsAtPath:[urlToAudioFile path]]) {
[[NSFileManager defaultManager] removeItemAtURL:urlToAudioFile error:nil] ;
}

but here is a much better solution, this should go into the rep

CheckError(ExtAudioFileCreateWithURL(audioFileRef, kAudioFileM4AType, &outputFileDesc, NULL, kAudioFileFlags_EraseFile, &_outputFile), "Creating file");

kAudioFileFlags_EraseFile does the trick, currently 0 is passed for flags.

Hi

When I uncomment the filewrite example code in the demo view controller, on the first run everything is fine, but on the second run,

CheckError(ExtAudioFileCreateWithURL(audioFileRef, kAudioFileM4AType, &outputFileDesc, NULL, 0, &_outputFile), "Creating file");

exits the app with error code -48, which is declared in MacErrors.h as duplicate filename.

I will try to find a work around this and post it here.

best
