Now I want to create a NSData object, initialized with the memory buffer, and pass it to AVAudioPlayer using initWithData:error: instance method. I wrote the following code, but when ...
I have this code to play a sound but the first time you play it it takes a good 5 seconds to load... How can I speed this up? -(IBAction)playSound{ //play the cricket noise NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"Cricket_Sound" ofType:@"mp3"]; audioPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fil...
What do you think is the best (i.e. most memory efficient) way of playing a few 30 second audio files (m4v) from the bundle within an app to the external speaker? The audio files have to play automatically as soon a specific view appears. There is no mixing, etc. going on. However I'm listening to the microphone at the same time via AVA...
Hi guys, I have a UITableView populated with a bunch of music players that I've made using a custom UITableViewCell. (as shown in the screenshot linked here: screenshot). The problem with the way I have it coded is that since each cell is completely independent, there's no way for one tableviewcell to check if any other the other cells ...
I have a simple mp3 playing through AVAudioPlayer and I want to be able to display how much time is left. I know the answer includes subtracting AVAudioPlayer.duration from AVAudioPlayer.currentTime but I don't know how to implement a function which calculates it while it's playing (like an onEnterFrame in Actionscript I guess). At pre...
I have a root view and a detail view, in the detail view is a AVAudioPlayer with a basic play/pause button setup. All works, however if I play the file and then click back (popViewControllerAnimated) to the root, the file keeps playing which is correct, but then if I click back to the detail view the view has reset and doesn't find the i...

I seem to have a bug because I'm using -[AVAudioSession setActive:withFlags:error:] in an iPhone project that is for 3.0 - 4.0.2. So I guess I need to put one of those #IF lines in, so I can get it to do different things based on the OS version... But I can't find out how to do it. Can anyone help please? Thanks! :) ...
I'd like to control an instance of AVAudioPlayer from a UITableView item in a didSelectRowAtIndexPath instance. First touch of the row item triggers 'play' of the AVAudioPlayer. Second touch of the row item triggers 'stop' of the AVAudioPlayer. I can make the 'play' work but can't get the 'stop' to work. Also, subsequent touches of t...

Ok, So I am trying to seamlessly loop together three sound files with the second file being looped against itself n times. Let's assume I can get them to loop seemlessly together in another program by butting them together. however when I use audioPlayerDidFinishPlaying delegate method of avaudioplayer there is a slight delay in the but...
