Hi :) I experienced trouble when I wish to get a stereo WAV at 44.1 kHz 16-bit signed. Basis is a Qtractor multi-track recording at 96 kHz 32-bit float.
In theory I could use any software as the mastering recorder, but I would prefer to use something like jack_capture, just in case that a production needs all the resources of the computer. So far I didn't checked out how to master + directly do the conversion / resampling when using jack_capture. While the stereo mastering at 96 kHz 32-bit float is ok [1], I wasn't able to do a converson / resampling that is suitable. I'm not talking about a loss for the sound quality being on the cards, but about added noise that is extremely loud, while the original mastering at 96 kHz 32-bit float is free of that kind of audible noise. I also noticed that the 44.1 kHz 16-bit signed WAV need more MiB as the original 96 kHz 32-bit float WAV does, mathematically nonsense. To cut the matter short. I tested different apps. What apps did you experienced as the best apps for doing the mastering and what apps for doing conversion / resampling? How do you master + convert? TIA! ;) Cheers! Ralf [1] by the way, for comparison of the sound quality with the multi-track recording I needed to import the stereo master by Qtractor, because Linux media players tend to reduced the sound quality and I always do take care of the settings PS regarding to Qtractor: There's something bad with the offset for audio clips. While it's fine that the offset will add negative delay, there are issues because of the values, when I try to compensate the latency. The offset will change at different BPMs. And it's impossible to e.g. compensate 5.3 ms, because I couldn't choose 5 ms, but I guess just 3 ms and 7 ms or something similar, regarding to the BPM. Yesterday I received an email from a friend who is a prestigious Jazz musician: "[snip] bitte ohne Computer!!!!!!! [snip]", on English "please without computer!!!!!!!". When prestigious Linux audio coders say that ms for jitter and latency are inaudible, they please should get more contact to prestigious musicians. Regarding to http://lists.64studio.com/pipermail/64studio-devel/2010-June/006847.html, I noticed inaudible "JackAudioDriver::ProcessAsync Process error JackEngine::XRun: client = Qtractor was not run: state = 2" when using Qtractor alone (without Rakarrack). I don't get this messages all the time, but I do get those messages. Btw. recording audio tracks by Qtractor will cause a loss of the audio quality, while there seems to be no loss, when I record audio signals by using jack_capture. _______________________________________________ 64studio-users mailing list [email protected] http://lists.64studio.com/mailman/listinfo/64studio-users
