diracLE~ is a high quality realtime timestretching and pitchshifting external.

It is based on the DIRAC LE algorithm by DSP Dimension. It can playback from a buffer~ with no latency, in streaming mode there is quite some latency though.

There are some limitations: the samplerate should be 44.1kHz or 48kHz and smooth parameter transitions are not possible. It can function in stereo, but the channels are not linked internally, so they can have slight offset.

The zip file contains besides the external and a helpfile also 3 Max for Live devices which illustrate what you can do with it.

(note: it is currently Mac only)

update: the object is now max 6 ready, it uses 64 bit precision in max 6 (and still works fine in 32 bit mode in max 5)

Thank you this is awesome! Actually having quite a bit of fun with a drum loop and the maxhelp file :)

This is a great external! Nice Work!
Is there a windows version coming soon? :)

Hey Timo,

Been hearing great things about this external/M4L devices, but I can’t get it to open in Max 6.1.8 64 bit. I can load the external when running Max in 32 bit mode. Although your update says it runs in 64 bit, I get the "…wrong architecture" message in my max window.

Any help, greatly appreciated.

Evan – I have exactly the same problem. Anyone able to help?

DiracLE doesn’t support 64bit binaries. Timo was referring to updating for Max 6’s 64bit audio sample based signal chain (which is separate from a 64bit architecture binary…I know a little confusing). Stay tuned for Max 7, where these kinds of features are available on both 32/64 bit architectures as well as other features above and beyond DiracLE.

Thanks for the clarification!
I guess I’ll have to wait until version 7 to incorporate this into my devices.

@Timo and @Joshua

Any news on x64 support for diracLE~?
