Mutagene has released an Audio Unit beta version of 2WarpDelay v1.5 for Mac OS X (Intel only).

2WarpDelay is a feedback delay featuring 2 frequency-warped lattice filters in the feedback paths. Lattice filter coefficients are scanned from a bitmap that can be user definable or are extracted in real-time from the input signal.

In some respects, probably all hidden, this version of 2WarpDelay offers some improvements to the latest Windows version (which was released in early 2008). Most notably it uses PNG as its native format, not BMPs. Eventually this may find its way to the Windows version. In other respects, some features are missing; WLPC mode is implemented, but not the cryptic bandpass filter mode.

All feedback will be gratefully accepted, but no promises for future development.
