Hi :-) Here's an example soundfile: http://footils.org/snd/23.wav With loopstart for example at sample 2912 and loopend at 5402, this looks pretty even in the array overlay, but if you listen to it, you can still hear a nasty rumble. I wonder, how to get rid of this ... I thing this is

Anyway back to the looping: With the fix, I can smoothly loop sine-waves now, Oh, and as for the sinewaves, if you set the loop start and end points at exactly the beginning and ending of one period, then the loop frequency is the same as the frequency of the actual content of the

Hi, not related to the thread on smoother audio in Pd, I am struggling with doing a smooth loop player for data stored in tables. One building block for this is attached: It is a simple tabread4~ lookup that should loop over a configurable section of a table and play it back with various

As I understand and as Matt already wrote, you wanted a transposition of the phasor~'s frequency (which would change the frequency of the loop but not the sample content), but instead you did the classic up/downsampling-of-the-soundsample transposition. (The distortion you get is due to the
