Perhaps, it could be a different (but possibly novel) way to visualize stereo audio spectrum (higher amplitude on one graph than other means closer to 90 degrees out-of-phase on certain frequencies, as opposed to full 180 degrees out-of-phase as in traditional L/R spectrum analyzers), where two differently-colored graphs represent magnitude part of complex-valued FFT; the first one is as it is, and the second one is same as the first, but the order is flipped since the input to the FFT data is complex-valued, thus not symmetric in the full FFT output and to be able to visualize complex-input FFTs with the frequency range of 20Hz to 20kHz and a logarithmic frequency scaleAlso, I think this topic is little bit de-railed; it went into performance improvements of multichannel audio spectrum analyzers by using complex-input FFTs, which is true considering calculating two or more FFTs can have significant performance impact. But what I really mean is that is complex-input FFT as in spectrum of I/Q signals in SDR really useful for analysis of stereo audio, which is basically the same minus the "unscrambling" operation?
I don't see any reason you would want the scrambled output when you could have the regular unscrambled one instead.

Anyone else see large random negative offsets being put in sycnched lyric files with V0.6. I think it happened with previous versions too. If I remove the large offset, can be somewhere around -78000, then the lyrics are prefectly synched. So it seems to be put in in error. It seems to happen comtinuously for a while, then it goes back to working fine. Lyric sources are from MusixMatch or Deezer.
Getting blank Clip count in my playlist with this new version. Before it said 0, now it's just blank. Using this string:
%truepeak_scanner_clipped_samples_track%
The albums I have included here are: Taylor Swift: the tortured poet department and Emmanuel Pahud, Éric le Sage: Mozart storiesOn the album Mozart stories, with the latest Picard 2.11 and rsgain 3.5, and the settings like below, I get album gain -4.39 dB. With the default target (-18 LUFS) I get -0.8 dB and with the default max peak (0 dB) I get +0.2 dB. That's similar to foobar.
