hi tahoma,

if i have some freetime i develope a plugin version with the dirac code. a little performance problem is that the LE version of dirac doesnt allow 2 channel in 1 object. but thats no problem if you use the plug "offline". maybe its possible to preview in realtime/mono with quality mode1.

This is what comes out on the program;
!<arch>
/ 1116595766 0 852

Well, sought of, could I program this thing on that program????

Oh, doesn't seem to respond to command lines.

That'd be cool! it's actually the best time stretch Ive heard in a while so I'd even be willing to pay for it!!

Cool, then they have extended the AU architecture. Still the time stretcher doesn't work anywhere else but in AU Lab, right?

Because XTal is a VST intstrument that reads the audio data from files. It doesn't need to process a data block from the host and return it...

ah, that makes sense...

free version of dirac looks to be perfect for a good quality free autotune...

Sounded like "good quality-free" AutoTune ...

It's the simple vst mp3 player I've been looking for for years.

but it can play wav's as well and the built-in filter isn't to bad...

There is no way to actually predict how many frames DIRAC needs per call and there is no guarantee that DIRAC requests an equal amount of frames at each consecutive call.
Please note also that the number of frames requested through your callback function can depend on a variety of factors, such as sample rate, DIRAC library version and selected DIRAC quality mode. You should therefore not make any assumptions about these figures, and take care that your callback function will handle all non-serviceable requests gracefully.
In particular, since DIRAC has no idea of how your audio channels are laid out and how much data they contain, make sure you catch any end-of-file condition that may arise from requesting data through your callback function.
Should DIRAC request nonexistent data, make sure you pass zero frames instead.

I am now really interested, how someone wants to solve that with a realtime processing plugin without any noticeble latency and/or allot of other problems that meight occur...

I'm not a software guy so I can't answer your question, but is it me or why are you so negative about things? Surely every problem has a solution and some clever minds will make it possible... others have done it before, too, so it can't be that hard...?

Dirac Timestretching anyone?
