It's getting a professional sample player! wow. :!:

perhaps some bugs:
-Raising rate +50 and lowering -50 resulted in lower pitch than the original
-Raising the tempo and then lowering resulted in an interesting echo ;)
-crashed wile lowering the pitch, after first raising the pitch, I did permanently play the sample.

The number is percent so that's correct.

You get best results using smallish values. Big values produce cool effects :)

Fixed.

Edit: Fixes.

I think, that you have attached the wrong revision - older one ;p

New version gives you 60 seconds to read the text :)

I'm beginning to notice a few issues with playback of longer files.

1. .WAV file playbacks are giving me clicks and pops, as if my CPU is heavily taxed. Windows Task Manager doesn't show any particularly heavy load, and the Buzz CPU monitor has AudioBlock at about 3.0% CPU, but the clicks are definitely there. Here is an upload of a file "before" and "after" being loaded into a fresh Buzz project consisting of nothing except AudioBlock going straight to master. I clicked "record loop" so (theoretically) the new file should begin exactly as Buzz starts playback.

I'll warn you that it's subtle and may not be noticable on speakers - I recommend headphones, with the volume all the way up (I promise there's no loud noises :lol: ). It sounds like vinyl surface noise - the incidental little clicks and pops on a generally-well-taken-care-of record. I also get the same "surface noise" when rendering loop instead of recording loop.

2. The files also "fail" an "inversion test" - inverting one of them, then mixing them together should, in theory, produce silence or near-silence, but here there's plenty of ghosting. This is less of a concern, I suppose, because you (or at least I) can't really hear a difference, and it may be unavoidable due to the very nature of Buzz WAV capture itself. But thought I'd mention it anyway.

3. mp3 playback seems... really problematic. Maybe it's due to sample rate conversion (mp3 can only be at 44.1 or 48k, and I run Buzz at 96k)? I tried both 320 CBR and V2, 44.1 and 48K (48k should in theory convert to 96k pretty easily), and they all sounded pretty terrible - 320 has the aliasing of an old-school Real Audio file, and V2 does all sorts of wacky things, you can hear when the encoder is switching bitrates and stuff. VBR might be a bit "modern" for Buzz, but it seems a 320 CBR file should be well within spec. The files play fine in foobar.

The source file in question is about 4:31 long (the versions in the zip file I linked are just the beginning), so that may be the root cause of my issue here :D Polac VST blows Audacity's crummy VST handling completely out of the water, so it'd be really cool to be able to use Buzz for second-pass mastering, or when doing "bounce-downs" when CPU starts maxing out.

1. Haven't noticed this. You could try different audio driver buffer sizes since there is some locking going on in AudioBlock to avoid thread collision.

2. I tried inversion test using 44.1KHz FLAC file and setting audio interface to 44.1kHz. Result is pure silence as expected. If your audio file sample rate differs from Buzz sample rate, you will get aliasing effect. To avoid/minimize this, you can resample the audio file from the right click menu.

3. AudioBlock uses the mp3 decoder in Buzz and I don't know what framework/library Buzz uses for mp3 decoding. The aliasing problem applies here as well. And to get the best output lossless audio format is the way to go.
