Hi all.
Is there software that someone could recommend that would provide a
visual indicator of clipping occuring in a jack stream? Extra points
if the visual indicator remains set until manually reset. Double extra
points if the program can run inside a (linux) command-line
environment?
You can use jack_capture and record to /dev/null
The red color shown when clipping is reset after around 2 seconds though,
but you can probably fix this quite easily in the source code.
Apply this patch:
diff --git a/jack_capture.c b/jack_capture.c
index 3f77c56..f62e883 100644
--- a/jack_capture.c
+++ b/jack_capture.c
@@ -647,9 +647,11 @@ static void print_console(bool
move_cursor_to_top_doit,bool force_update){
vu_peaks[ch] = pos;
vu_peakvals[ch] = val;
vu_times[ch] = 0;
+ /*
} else if (vu_times[ch]++ > 40) {
vu_peaks[ch] = pos;

+ */
}
and run this line:
while true ; do jack_capture /dev/null ; done
then you can reset peaks by pressing return.
