I am developing an application which has to capture sound from a 4 stereo line in card (total = 8 channels) and I need to do the following: - Wave files must be in "7000 Hz. 8 bits mono" format (minimun accepted by hardware capture device = 32000 Hz.), if we can''t record in 7000 Hz., how can i convert it while saving. - Each channel must be recorded separately(8 wave files), how can i record each channel(left or right) individualy. - All channels have to be recorded simultaneouslly, but they can be started at different times. If anybody can help me with any of these topics, I would apreciate a lot. Thanks
