[LAU] capturing spoken text -- alsa settings

Hi!
  If I'm not too far wrong; Turn the mic up as high as it goes, without being 
in the red zone. Thus you capture even relatively low sounds and have a max 
range. See that your room doesn't contain disturbing noises, like 
computer-humming and other stuff. Make sure your mic isn't too noisy.
  About plugins: If you have a regular alsa installed, and I don't know why 
you wouldn't, then you have all you need here.
  Exceptions: You can't really store soundfiles on disk with your app, then 
you'd need the file-plugin, but I believe it's still included in alsa, if 
that's not the case, you need to install alsa-plugins package from your 
distro.
  The rest you'd need would simply be for editing. Mostly ladspa/lv2 plugins 
and other software to denoise, compress/expand, filter...
  HTH.
  Kindest regards
        Julien
