iPhone: Merge 2 mp3 files

Question

Can some body explain how we can merge 2 mp3 files on iPhone? is it possible?

Answer 1

Try the following code, it is for concatenation not for mixing. Haven't tested myself, but I will soon

NSMutableData *part1=[NSMutableData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"part1" ofType: @"mp3"]];
NSMutableData *part2=[NSMutableData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"part2" ofType: @"mp3"]];

[part1 appendData: part2];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *mp3file = [documentsDirectory stringByAppendingPathComponent: @"test.mp3"];

[part1 writeToFile: mp3file atomically:YES];

I think it should work
