Hi,

I tried to get the kAudioFilePropertyEstimatedDuration property,
but I always receive an error ( NSLog(@"property error") ) 
and the value of seconds is 0.
What am I doing wrong ?
I would be very thankful for an answer.

Karsten


-(void) duration

{
NSURL *inputFileURL = [NSURL fileURLWithPath:PathName];
OSStatus Error = noErr;
ExtAudioFileRef file;
Error = ExtAudioFileOpenURL((CFURLRef)inputFileURL, &file); 
if(Error != 0) NSLog(@"file not loaded");
NSTimeInterval seconds;
//Float64 seconds; ??  
UInt32 propertySize = sizeof(seconds);
Error = ExtAudioFileGetProperty(file, kAudioFilePropertyEstimatedDuration, &propertySize, &seconds);
    if(Error != 0) NSLog(@"property error");
NSLog(@"duration: %f", seconds);
if(Error != 0) NSLog(@"error");
        //printf("duration %f \n",seconds);

ExtAudioFileDispose(file);
   
}
