I'm using Core Audio / OpenAL to play CAF audio files. From Apple I know that the best file format is this: Core Audio File Format (CAFF), mono, 16-bit @ 44,1 kHz So I launched Soundtrack Pro 3 and saved an WAV file as an "Core Audio File" with 44,1 kH, 16-bit integer. When I play it back, it is strongly distorted and has a horrible q...

I tried the MPVolumeView it works like charm, it even controls the device volume even after you close the app, just like the iPod app. My question is, is there anyway to custo...

Is it even possible to enable the HDR option from within my application? I assumed it would be there automatically. I looked for additional mediaTypes, thinking maybe kUTTypeHDRImage might be an option, but no such luck. It's not an additional source type, nor is it available through cameraCaptureMode. ipc.sourceType = UIImagePickerCon...
