Thanks for the suggestions. This is really useful as I didn't know that you can format messages for soundfiler like that. </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">
So I made all of your suggested changes but I'm still getting the funny noisy playback. It sounds almost ring-modulated (e.g. you hear a lower-frequency sideband at around 10 seconds into the file, which isn't in the input file).

<div dir="ltr">Hi Peiman, I notice a few things:<div><br></div><div>1) your soundfile is being truncated to 4000000 samples</div><div><br></div><div>2) you're loading the left channel of your stereo file into both arrays</div>
<div><br></div><div>3) after calculating the correct frequency for phasor~ to play at normal speed, you're multiplying by zero.</div><div><br></div><div>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:</div>
<div><br></div><div>read -maxsize 6.24e+06 -resize $1 test_L test_R</div><div><br></div><div>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.</div>
<div><br></div><div>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.<br><div><div><br>
