I've made an iPhone app to be used while exercising. It plays a bell tone to indicate that you (the user) should switch from one step of your exercise routine to the next. I've designed the app so that you can listen to music on the iPod while using the app, and I want the tone to play sufficiently audibly over the music. I've gotten t...

I'm using an AVAudioPlayer to play a mono AIFF file from my app's Documents directory. On the simulator, [player play] returns YES and I hear the file playing. On the device the play method returns NO and nothing happens. I grabbed the file via the Organizer - it plays back fine on my Mac and seems to be well-formed. I realize the simul...

Then I went back to Google. Turns out I'm having almost the same exact problem as described in this post, unanswered from June. http://www.iphonedevsdk.com/...

When a cell is touched the navigation controller moves to a tab bar controller and the "root" view of the tab bar controller has a button that plays an mp3. My question is this.

Hi Everyone: I am wondering if there is some way to fade in and out audio using AVAudioPlayer in CocoaTouch, with a pause command once the music finishes fading and then a play command once the fading begins. I have heard that one can use NSTimer for this purpose, but I am unsure of the easiest way to accomplish this. Thanks for any h...
I'd like to be able to play back audio I've recorded using AVAudioRecorder @ 1.5x or 2.0x speed. I don't see anything in AVAudioPlayer that will support that. I'd appreciate some suggestions, with code if possible, on how to accomplish this with the iPhone 3.x SDK. I'm not overly concerned with lowering the pitch to compensate for increa...
