Normalizing the Master Audio Output On The Fly?
 
Hello,

I've been trying to figure out a solution to this for the past 3 hours and haven't found any satisfying answer.

I've already had some grief because of volume levels from different sources tending to be disparate. This includes music, video, cd/dvd, and now the lastest annoyance being flash games without volume control being extremely loud so i have to put the level at minimun, but then when I want to hear music or watch a video I need to ajust the audio level again.

What I'm looking for is an application that would normalize the audio output level of my pc so that I don't need to constantly adjust the master audio level.

Hi.There is an excellent command line program called "normalize".Try typing it into a terminal too see if its installed. If not use your package manager which I think is apt in Sidux,to install it.Once installed,go to the folder where you want to run the program.Right click and open a terminal.type normalize -m *.mp3 changing the *.mp3 part to whatever file type it is .eg ogg,flac etc.

I know about programs to normalize audio files, like normalize-audio, mp3gain, aacgain, but what I need is an on the fly normalizer for the sound output of my pc.

What you're looking for is a compressor/limiter, and I'll guess your sound system is ALSA... thus a search for those terms brings up using LADSPA plugins for standard ALSA apps which details how to create a new audio device with a LADSPA compressor plug-in hooked on for applications to output through via the .asoundrc file.

That's a system-wide solution for every application that lets you choose the output device, although you could probably set it up on your default device easily enough.

Thanks for your suggestion technomeister.
That solution does seem to fit though it looks more complicated to implement than I had hoped for. I'll look into it when I have the time though.
