Hello, 

I tried with different bit depth and it doesn't make a difference. 

It sounds like it has to do with sampling precision of phasor~. And the fact that changing the sample rate makes a difference to the way that vline~ works also suggests to me a global issue. 

I'm actually using the 32-bid build for now as non of the externals I'm using have been built for 64-bit. 

Thanks
Peiman

I was thinking it might be related to your file's 24-bit sample encoding and was going to suggest soundfiler's "raw" message to be specific about that. But if you're getting perfect results with vline~ and not phasor~, it sounds like that's not the issue. Are you using the 64-bit Pd for OSX?

But it doesn't end there. It's also an issue with phasor~. At the right sampling rate, it works with vline~ but not with phasor. As in phasor introduces those noises.

I think I have it figured out. Problem was inconsistency between the PD sample rate and the soundfile's sample rate. Not sure how that works but it seems to add some sort of ring modulation to the result.

Also, even with the array max size of 2^24 I'm still getting the noise.

Oh I see. So it's to do with the size of the array. Thanks for that. 

Now, is there a workaround, other than reading the file directly from the disk?

Best,

An
artefact of the sample interpolation perhaps?

No, of limited precision in the index:
