Hello Alsa-Developers, currently I try to decide, if ALSA is useable for a certain multi-channel signal processing task. I've read, that even with a realtime kernel the input-output latency varies with time - especially if USB is inbetween. Even so this is not what I actually want, I think the application might be sufficiently robust against this. However I expect to require a fixed latency between multiple ( I2S ) channels. This shall include stereo, but extend to all channels ( between 6 to 12 mono / 3 to 6 srereo channels probably ). So every channel's signal shall be exactly determined to its relative position with respect to the other channels, e. g. it shall be known inside the system which events occured simultanously. Likewise, the processed or generated signals shall be transferred to the outputs in a way, that they occur there with intended and modifiable relative latency to each other. Is this ensured by the ALSA architecture or is it at least possible to ensure it, if it is used? Any comments or answers are appreciated. Kind regards Christian _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
