Automatic Volume Level Control - AGC - with the LINUX Audio APP - VLeveL - Live demo

using MUMBLE and MORSE CODE audio tones, and varying the Mumble output volume from 15 percent to 200 percent, this video demo's VLevel keeping the volume output of Mumble to be extremely stable at a near zero DB final audio output to the sound card, no matter the level of volume at VLeveL's input...VLevel is acting as an AUTOMATIC GAIN CONTROL, and you can set how low in volume you want VLEVEL to go and still output the same "near zero db" output volume...at the settings shown in terminal, VLeveL, will raise the audio volume level from all the way down to -30 db, up to anything higher than that, and output a very stable, steady output audio final volume of near zero db.
