Use 0×01 instead of fsRdPerm.

Well, I’m using sdk beta 8. I tried to modify this example to be able just to play ANY long sound on iPhone, as long as I dont have any mic I have no chance to use original example provided by Pete. Anyways, I try to play “caf” files, but it gives me just lots of noise instead of sound. Wav files shows me “Playback failed” statement, MP3s just crash iPhoneSimulator. Any ideas how to organize playback on iPhone will be really appreciated.

Thank you for the example. I test these files on iPhone SDK 5, get UIButtonType error. I change it to other UIButton types and has EXC_BAD_ACCESS error on the iPhone Simulator. Does anybody figure it out?

Can any one comment on whether or not this works with the sdk v5? I run it but the UI never gets created even though NSLog’s added to the beginning and end of applicationDidFinishLaunching are getting fired.

I’m trying to play some mp3 audio clips from a packed binary file, and I’m having a hell of a time figuring out what approach is appropriate. I was looking at the streaming stuff, but before that I tried just saving my binary chunks out as files, and then playing them using something like your code above. Everything executes, but no sound is played, and no errors occur.

I’m very frustrated. I just don’t understand why playing audio has to be so damned complicated.

Hi!

How do I play compressed audio formats?
I’ve just found some demo code @apple dev site, but this code freezes always the GUI and cannot return after playback…

Any idea?

I’m able to record and play back audio on the simulator. It just uses the computer’s sound card.

The apple samples work for me both in the simulator and on the iPod Touch. I had to download the new versions though.

Interesting that it works in the simulator when it doesn’t have a mic !
I thought you were testing it on the iPhone itself.
What do you mean by working on the simulator? Can you actually record and playback the recording and hear your voice?
I only get the “Record Failed” error in the simulator.
I still haven’t figured the EXC_BAD_ACCESS error on the iPhone, but it finally looks like it is tied to the certificate issue since I get the same errors with the new demos.
What a game, seriously!
