Funny business in VuMeter OnPaint

[Carmine Casciato]

Hello pyo,

Just got the latest revision and scared my neighbors half to death
when a wall of noise came out the speakers upon starting up the
examples.
Error message corresponds to OnPaint in VuMeter in _wxwidgets.
Error message:

Traceback (most recent call last):
File "/Library/Python/2.6/site-packages/pyolib/_wxwidgets.py", line
582, in OnPaint
width = int(db*w)
OverflowError: cannot convert float infinity to integer

Quick test:

Took out the VuMeter in the nuages example i.e.
s.gui(locals(), False, False)

No more error, but wall of noise still present. Too scared to
continue ;)

Hi Carmine,

The VuMeter error is just a side effect of something else... When it receives an amplitude of "inf".

You got it with nuages example ? Just tested it, works fine here...

What is your system ? Python version ? compiler ?

Hi Olivier,

Apple gcc 4.2.1, Apple Python 2.6.1, on OX 10.6.7, using JackPilot or
system audio.

There is definitely something funky going on with the examples for me.

The nuage example is now giving this as an error.

File "examples/nuages.py", line 24, in <module>
tabs.append(SndTable(snds[i]))
File "/Library/Python/2.6/site-packages/pyolib/tables.py", line
1114, in __init__
_size, _dur, _snd_sr, _snd_chnls = sndinfo(p)

So I tried some another example, freqmod. A (loud) burst and then
nothing. So I tried the simple sine wave example and it worked fine,
the gui and vumeter and everything. So now I am just confused. I am
going to re-fetch the library, see if that helps. I'll let you know.

Cheers,
Carmine

Maybe there is something wrong with Portaudio, sndinfo() uses it. How did you install the dependencies ? There is a shell script in the scripts folder that download and install libs and headers I use for portaudio, portmidi, libsndfile and liblo...

freqMod.py works for me, on 10.6.6.

Hi Olivier,

[Olivier Bélanger]

Sorry,

scripts/get_dependencies.sh !

I had forgotten to get the dependencies for this revision, I hadn't noticed that they were different than the last time. There were fewer 'deprecated warnings' when I recompiled this time, but something is still not working. Gonna clean everything up and try again tomorrow.

Thanks,

Carmine
