mpg321 volume

[artesvida]

I have a small server that I'm using to play hold music for our phone system. It works great, but the volume is inadequate. As far as I can tell, mpg321 is playing as loudly as possible. From the script:

mpg321 -o oss -a /dev/dsp -g 100 -q -@ $playlist

A few questions: Is there a way to get mpg321 to play more loudly? If not, is there a way to get these mpg files to be "louder" when played? Finally, this setup uses the audio that's on the motherboard (it's an older HP PC) -- will I get better volume with an add-in audio card?

I'm looking to avoid having to purchase a headphone amp for this setup.

Thanks!

I don't know a solution, but depending on your audio files, you could try this workaround:

Open the files in Audacity and run Effect > Amplify.

You can use mp3gain to increase the gain of your mp3 files:

mp3gain -g i some.mp3

Where i is a number of your choice.

Mp3gain is available in the repositories.
