I am using Ubuntu as OS and I am recording the audio using sounddevice Python package in a custom application.

Is this even determined by the hardware or is this a software feature? What specification determines this feature in an audio interface? But using the same method for recording, the software which listed 4 sources with 2 channels each, just displays 1 input source with 4 channels for the UMC404HD.įor my application, I require to start the recording for each source independently of each other. expecting 2 input sources (Line 1/2, Line 3/4). This interface was too old and needed a new interface for a new PC, so I got the Behringer UMC404HD, thinking I could do the same with its 4 input channels. I was using a PCI audio interface M-audio DELTA 1010LT, which had 8 input channels and it allowed me to record 4 independent inputs pairs, this is, the software recognized 4 sources (Line 1/2, Line 3/4, etc).
