This is great thanks you so much!!

But please can I ask your advice, for the life of me I can’t get this to work…

format->mSampleRate = 8000.0;
format->mFormatID = kAudioFormatLinearPCM;
format->mFramesPerPacket = 1;
format->mChannelsPerFrame = 1;
format->mBytesPerFrame = 1;
format->mBytesPerPacket = 1;
format->mBitsPerChannel = 8;
format->mReserved = 0;
format->mFormatFlags = kLinearPCMFormatFlagIsBigEndian |
kLinearPCMFormatFlagIsSignedInteger |
kLinearPCMFormatFlagIsPacked;

Always comes back with format error which is most frustrating, and I can’t find any info on this anywhere - well apart from here - and I really need to use 8 bit.

Thanks in advance

Hi, thanks for the tutorials. I have been researching around for 3 days on how to play two audio files at the same time on my iphone. It mostly crashes. At one point I had it working well on the simulator but it crashed on the trials on the phone. I tried making 2 audioplayer objects derived from the same audioqueue with no success.
Any help would be greatly appreciated.
