Thanks you very much Steve, for follow up.

These .caf files are played on device.
We have tested on simulator and found that .caf files were not played on simulator but .wav files are played on simulator.

Thanks,
Pravin

Do a debug build and then post the complete console output from CocosDenshion.

Edit: and make sure you are testing on a device and NOT the simulator.

we are playing background sound files by following code
// Preload the sound
[[SimpleAudioEngine sharedEngine]preloadBackgroundMusic:@"bgMusic.caf"] ;
// Play the background music
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"bgMusic.caf"] ;
But the same sound file of wave format will play with same code
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"bgMusic.wav"] ;

Yes , my code is based on Sapus Tongue from June last year.
Now we have added the CocosDenshion in our code.
(We are converted .wav to .caf by executing following command from terminal : afconvert -f caff -d ima4 bullet_fire.wav ).
These .caf file are not played using CocosDenshion library but the same .wav files are played.
Please help us.

CocosDenshion is free and ships with cocos2d. I recommend you use the version in the 0.82 release of cocos2d as that will be compatible with your code if it was based on Sapus Tongue from June last year.

Thanks Steve , but from where we get this CocosDenshion library files.
Should we need to purchase it ?

We are running following command from terminal to convert .wav file to .caf
afconvert -f caff -d ima4 bullet_fire.wav

Sapus Tongue is now using CocosDenshion for its sound engine. I recommend you upgrade, CocosDenshion can play caf files with audio encoded as IMA4.

More info about CocosDenshion is here:

How did you make the caf file? Try:

afconvert /path/to/test.wav /path/to/out.caf -f "caff" -d "aac " -v

Hi Everyone,

We buy "Sapus Tongue" code in the month of June 2009 which is very helpful to us to develop the games in cocos-2d.
We are developing game in cocos-2d , we have number of sound files (in .wav format ) to play in game (almost size of 37MB).
So we have converted these sound files to .caf so (size is 9 MB).
We have problem with playing sound these .caf files using "SoundEngineManager".
We would like to know this "SoundEngineManager" will support which types of file format other than ".wav" ?
Is there any other class to play ."caf" files?
Please guide us.

Thanks
Pravin
