nothing running beside Pd, freshly booted windows xp. afaik there is no option in pd to adjust buffer size, but it seems that Pd chose the bigest possible buffer size or what does "ASIO: input latency: 1440, output latency: 1440" mean?

I'm running a Pd patch with an oggcast~ object running that consumes around 20% CPU on a 1.6 GHZ Pentium-M with a USB audio card.

Hi, do you have some high priority software running apart from PD (like task manager)? Does it become better with higher buffer sizes?

thanks! Thomas

i have droputs every second to a few seconds. should i record the audio and send it to you (ogg or mp3)? pd's log window says:

i don't think that's necessary ... i had the same problem earlier, but solved it for my quattro (don't remember how)

ASIOGetBufferSize min: 96, max: 1440, preferred: 192, granularity: 96 ASIO: using traditional scheduler

i changed the asio buffer size to the maximum buffer size ... in your case 1440, that's not a multiple of 64, so you are not using the callback based scheduler ... i'll somehow have to implement a feature to select this, but don't know, where ...

and i wondered why it says traditional scheduler :-). maybe you can change the buffer size from maximun to preferred again. is preferred the value you set in the control panel of the audio device or normally a hard coded value in the audio device driver? (i guess this differs from card to card). I think the way to go is to open the ASIO driver's control panel as most audio software does it.

i think, i know, how your clicks sound like, but you can record a short bit and send it to me (privately, and please only a few kb ... slow dialup connection)

just realised that i need am adapter from RCA to mini-jack. but it sounds really like normal dropout, when buffer is to low or computer to slow.
