For me it fills my needs so far of what I wanted to accomplish with the component

Does anybody have a issue with updating EffectDSP? I'm using portable fb 2.1.3 and every time I try to install newest version of EffectDSP 0.50 final it shows in components list 0.50 beta 7... and I'm able to update it over and over - restart after restart version stays same 

There won't be anything adjustable in the various algorithms.

I use DSP Effect's Tempo Shift ability a lot.

With the SoundTouch algorithm I get a sound that has a bit of reverb in it. Is there a setting I can change to cause the slowed down audio to sound cleaner? Or am I just hearing things?


Attaching some audio files recorded when using DSP Effect version 0.47 and one file from version 0.51.

The Rubber Band audio clip is included for the purpose of comparison.

The Rubber Band and SoundTouch clips are playing at: Tempo -65.88 %
