Hi list :) because Daniel referred to http://www.audioprointernational.com/news/1322/Dinosaur-JR-album-recalled-due-to-mastering-error some days ago I guess the following might be from interest for anybody who records mono signals to stereo tracks. There seems to be some pitfalls for digital recordings that aren't there for analogue recordings. Seemingly also for stereo, but here's something about mono.
Maybe recording applications should enable mono tracks. Recording mono signals to stereo tracks is fine, but there's a pitfall: Hi Rui :) while making a soundfont I right now will record an Oberheim Matrix-1000 by it's mono output, without looping the signal through my (mixing) console, but directly connected to the sound card. System capture_1 is connected to Qtractor Master/in_1 and Master/in_2, while I listen to it by monitor enabled for Qtractor. Qtractor Master/out_1 is connected to system playback_1 and Qtractor Master/out_2 is connected to system playback_2. The outputs of the sound card are connected to my console. If I listen to it in stereo it sounds like a good mono signal, but if I listen to it by mono it sounds like a less clean mono signal. It's nearly a perfect mono signal, but there seems to be minimal phases. This isn't a problem, I'll use Qtractor as sequencer to play the needed voices for the samples with a defined velocity and length and will record the synth in mono by Audacity instead of recording them by Qtractor. It could be a problem if somebody like to record mono equipment without using a console, because there seems to be no way to record mono tracks by Qtractor. Assigning one channel to two channels by Jack doesn't result in a clean mono signal. This isn't a serious issue that needs a fix in the near future, but you should enable mono recording. Perhaps this is something you already planned to do some day. It makes me wonder why a signal recorded from the console by Qtractor seems to be fine when listening to it in mono, but a mono signal split by Jack and connected to 2 channels does sound like 2 signals in nearly perfect sync. As I mentioned before, it's not noticeable out of phases if I listen to such a mono signal in stereo, doing this it sounds like a mono signal, there's no widen effect noticeable, but a loss in the sound quality when listening to the signal in mono. Qtractor is version 0.4.2.1374. I don't understand what's the difference between a mono signal that becomes a mono signal for stereo by an analogue console and a mono signal that should become a mono signal for stereo by Jack. Because such mono signals from the console recorded by Jack and Qtractor will sound like a clean mono signal when listening to it in mono. It doesn't seems to be a sync problem by Jack or Qtractor, both seems to work fine. It seems to be a mathematically issue. A mono input to an analogue console that becomes a mono signal for the stereo bus might be a real mono signal, while a mono signal split by Jack to 2 channels might be a doubled signal. Dunno ;).
