[PD] About internal delays
Hi, all My first post.. how exciting =) Well anyway...just one quick question. Does the audio buffer size that can be adjusted with -audiobuf flag stay constant all the time? Or is it something that PD adjusts dynamically in case of dropped frames or something? I been having some delay related problems and it seems that sometimes it changes quite randomly. The problem might also be with my hardware so now I'm just trying to find the source of the problem. Thanks... -Mika ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] About internal delays
welcome to the pd-list! I am not sure, if many people still use the audiobuf flag, but I think it works... (another method would be to set the buffer in the audio settings.) and yes, it should stay stable during the whole time. what where the problems you had? because if the audio buffer is too low and Pd cannot handle the amount of data, the sound is shut down. usually a large buffer allows you to more complicated calculation (but increases latency). marius.

Re: [PD] About internal delays
Hmm... Okay. Then the problem should be in the hardware. I'm doing this kind of room impulse response estimation with nlms method and I get nice impulse response but if there is some cracks in the sound (from cpu load and dropped frames I assume) the impulse response shifts with random delay which shouldn't happen. I am using RME Fireface 800 audio interface in windows xp environment. Does anyone knwo if that might cause some problems?? -Mika Quoting marius schebella [EMAIL PROTECTED]: welcome to the pd-list!
