Subject: help for a levelmeter
Date: Tue, 15 Oct 2002 23:15:44 +0200	[thread overview]
Message-ID: <3DAC8580.7010004@club-internet.fr> (raw)

  Hello,

I 'd like to make a levelmeter program which would display sound card
input/output
while the audio device is opened by another program. I tried to use copy
plugin  , but now (since 0.9.0rc3 ) the "snd_pcm_copy_open" give a "implicit
declaration of function"
message . (Anyway, i don't know if using this plugin was correct for
that purpose)

So, would you know a way to read audio data going to (or coming from)
the device , when it is opened by another program ?

Thanks for any help!

Laurent
