Trouble with iOS 4.3 Dirac3 LE and audio loops

[batbass1]

I’m trying to solve this problem:
I’m using the last version of Dirac3 LE for stretching mono drum loops in iOS app. They are uncompressed .aif and the app is realized with Xcode 4.2, compatible with iOS 4.3 and later.
Well, when the loop starts again you can hear a little, very little gap or a light glitch, probably dipending on the amount of samples. Loops are perfectly smooth if run through other iPhone applications like Amazing slow downer or even through apple music “loop1” function. It should be something related to iOS library or maybe a memory leaking issue but the developer told me that the problem is that is Dirac to processes anyway the audio, even when you don’t use the slider for stretching time or pitch. I really wish to use the time stretching function in my app so…I don’t know: maybe does it depend on which iOS library you use to manage audio in conjunction with Dirac? Did you ever experience this type of problem? Can you please give me any suggestion on how to solve this issue? I have already payed the developer but this way the app is not usable (SOB) so I’m struggling for solving that. I wish I could attach a snapshot showing the framework chain, anyway MediaPlayer, AVFoundation, Core Audio are involved among others.
Thanks a lot in advance

Hi Mauro,

thank you for your interest in Dirac. This is almost certainly not a problem related to Dirac itself (as Amazing Slow Downer also uses it). If you don't mind sending us the code for your project to take a look I'd be happy to check it out. You can contact me at smb [at] dspdimension [dot] com.

Great! Thanks Stephan, you are really special!!
I will send you the code ASAP.

A big hug
