Re: [Alsa-user] Consecutive overlapping tracks

Suppose we start recording from a microphone via a single sound card. Just a few seconds before the recording ends, we want to initiate another recording. An so on. Well, I believe it has to do with sound cards since when I try to do it, I receive a device or resource busy error because when the second recording starts, the sound card is already occupied by the first recording.

In other words, the beginning of a track will be some seconds earlier in time than the end of the previous track. If this is not possible, I would at least like to achieve gapless recordings (with no missing samples between subsequent tracks). Are the singers/players/ actually playing overlapped? Then a microphone will pick that up and the sound card will not distrub that. If what you mean is that you want to record those 5 tracks at different times/places, and you would like the final format to be as below, then that has nothing to do with sound cards. That is post processing, using your favourite sound editor (eg audacity will do what you want). But alsa does not get involved. Alsa has to do with getting the sound off the sound card into the computer as it occurs, everything else is the duty of some other programs. So no, you sound card cannot remember what that source played a while ago and output that together with what is playing now. The computer can. I hope the following figure helps. |-Recording period---| |-Track1-| |-Track2-| |-Track3-| |-Track4-| |-Track5---| ---| |--- Overlapping period (and track 1 and 4 overlap?)

Usually one records the tracks, which one uses the soundcard for, and then one overlaps them in post production. (eg audacity). Or you can have the two singers singing over each other during the recording. So perhaps you should be a bit more detailed in what you want to do.

Hi You need to use index option when loading the modules, with usb devices you also have to specifythe id of the device.

For M-audio the values are Bus 002 Device 005: ID 0763:2012 Midiman Note that in the modules.conf both hex values (0763 and 2012) are prefixed with '0x'. HTH -- mr.
