Re: [PD] tabread2~ noisy output
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?

Re: [PD] tabread2~ noisy output
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.

Re: [PD] tabread2~ noisy output
Hi Peiman, I notice a few things: 1) your soundfile is being truncated to 400 samples 2) you're loading the left channel of your stereo file into both arrays 3) after calculating the correct frequency for phasor~ to play at normal speed, you're multiplying by zero. With 3), maybe you have that there so you can scale the playback speed with a control later. But re: 1 2, try a message to soundfiler like this: read -maxsize 6.24e+06 -resize $1 test_L test_R That will increase soundfiler's default maxsize so your complete sample can be loaded. Also note that with the read command you can list 2 tables to load to with stereo audio files. You had those tables listed in separate messages…with 2 separate read calls, soundfiler is starting over each time and has no way of knowing that you want to continue where you left off. I didn't listen carefully with headphones, but after those changes I didn't hear an obvious difference between tabread4~'s playback of your file vs. my web browser's.

Does someone know why the result is so noisy? Please try with this sound file (96k 24bit): https://dl.dropboxusercontent.com/u/47945259/test.aif. It sounds like some sort of extreme quantisation noise. But maybe I've missed something in the patch. I'm on the latest version of pd vanilla on os x 10.7.5.

[PD] tabread2~ noisy output
Attached is a simple patch that reads sound file data from an array with tabread4~. Does someone know why the result is so noisy? Please try with this sound file (96k 24bit): https://dl.dropboxusercontent.com/u/47945259/test.aif. It sounds like some sort of extreme quantisation noise.
