Error when leaving output pulse_out(liquidsoap:): File "source.ml", line 414, characters 10-16: Assertion failed! #539

this works liquidsoap 'out(ladspa.noise_white(amplitude = 0.01))'

what is not working (if I change ladspa.noise_white per sine it works):

#!/home/user/.opam/system/bin/liquidsoap
set("log.file.path", "/tmp/liq.log")
msg = random(weights = [1, 2, 5],[single("say: hello"), sine(480.0, amplitude = 0.2, duration = 0.5), blank(duration = 1.0)])
signal = add([ladspa.noise_white(amplitude = 0.01),msg], normalize = true)
out(signal)

log

Thanks for reporting this, will have a look at it.

Ok, sorry it's not a bug. The ladspa operator needs a mono source. You can convert the source to mono this way:

signal = add([ladspa.noise_white(amplitude = 0.01),mean(msg)], normalize = true)
