I've tested again the (really cool) audio features of QLC+, unfortunately hit some bugs / issues:
* Using "Audio Spectrum" in "RGB Matrix" without audio input crashes QLC+
To reproduce: Add some RGB fixtures, create a "Fixture Group", create a new "RGB Matrix", select "Audio Spectrum" as "Pattern" while there is no audio input -> QLC+ immediately crashes with a "Segmentation fault". Editing an existing "RGB Matrix" with an "Audio Spectrum" pattern will also crash QLC+ when there is no audio input, eg. in the silence between two tracks.
* Audio input could not max out the display in QLC+
Neither in "Audio Spectrum" of the "RGB Matrix" nor in the "Audio Trigger" in the "Virtual Console" it is possible to either light up all fixtures in the "Fixture Group" or get 100% in any "Audio Trigger" bar, even if the audio input is way above 0dB. Either there is an issue mapping the "loudness" of the audio input to the scale used by QLC+ or a kind of "Gain Control" is missing.
* Invalid Values for Colors
While playing with the audio features there were several debug messages related to color values, e.g:
> QColor::setRgb: RGB parameters out of range
> "QColor::setRed": invalid value 5933
> "QColor::setBlue": invalid value -17034
> Returned value is not an array within an array!
* "Audio Trigger" does not work with 32 "Spectrum Bars"
To reproduce: Create an "Audio Trigger" in the "Virtual Console", set the "Number of Spectrum Bars" to "32" -> The "Audio Trigger" widget displays empty spectrum bars, regardless of the audio input. Reducing the the "Number of Spectrum Bars" to a lower value, e.g. "31" makes the widget work again.
Hopefully my descriptions are detailed enough to track down these issues, thanks for looking into it!

hi,
Im having this same two problems on osx. QLC just crashes as soon as I try to use any audio triggers.
Seams that audio triggers do not work at all on osx.
Im new to QLC so maybe I have not setup audio correctly?
Instuctions in this area are very limited. Any chance someone could do a walk through youtube video?
Help anyone lol....

Hi,
Same issues here!
The system totally clips on the audio level but qlc only shows half bars or something.
Max 31 bars, took me some time to figure this out. I have 2 lines on the side to give some VU effect to solve this.
If use the .deb from the qlc website i can select an audio capture different from default, but nu luck to get it to work.
If i build from git i can not select the correct soundcard, There is only the default but there is no signal.
Widows 7 on the same laptop the audio triggers give some signal but more than half bar height no way!
