Bit depth doesn't matter. The built-in test signals output the same bit-depth as usual i.e. 24 for SB3/Transporter.
Sample rate for the built-in test signals depends on the track being played "behind the test tone". If you want 44.1 music to sound best, then you should play 44.1 tracks for the test signals, and make sure your audio interface is recording at 44.1kHz without resampling. If you want 48kHz music to sound best, you should play 48kHz tracks for the test signals and record them at 48kHz. (And the same for 96k too). The .drc files which ship with DRC are intended for 44.1kHz and won't be right for other sampling rates. There's been some discussion on the drc-fir-users mailing list about how to edit .drc files for different sampling rates; I don't think it's particularly difficult, but haven't tried. Anyhow, you end up with a correction filter -- at the sampling rate you recorded the sweeps at. InguzDSP will use this filter for tracks played through SlimServer *which match the sampling rate of the filter*. For tracks with other sampling rates, the filter gets resampled to match. This uses "sox polyphase" by default, so it's pretty good quality, but might be noticeable. So if you listen to most of your music at 44.1 (CD), then you should record the sweeps and produce filters at 44.1 too, to be guaranteed that the filter quality won't be affected by resampling. -- inguz ------------------------------------------------------------------------ inguz's Profile: http://forums.slimdevices.com/member.php?userid=1139 View this thread: http://forums.slimdevices.com/showthread.php?t=38534 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/plugins
