Converting mono to one channel of stereo
Purpose. Converts mono audio or stereo file to a stereo audio file with the mono stream appearing either on the left or the right channel of the stereo stream, and the other channel muted. If the input is stereo, it is mixed down to a mono stream, which is then used as above. Besides the number of channels, the output file will have the same audio format as the input file.

Bugs, limitations. The converter processes only audio data in common PCM formats (8 bit unsigned, 16 bit signed). To process stereo input files, the PCM2PCM converter of Tritonus is required. You can download it from Tritonus Plug-ins.
