How to increase the volume for an avi file

I have one or two .avi files for which the sound is simply too low. I like to play them in vlc, and enabling the graphic equalizer helps somewhat, but is there any other (easy and quick!) way of increasing the volume? Thanks!

"You could use VirtualDub for this. This guide has a short and straight-forward explanation.

Brief:

-

Start VirtualDub and load in your
converted DivX file.
From the ""Video"" menu, select ""Direct Stream Copy"".
From the ""Audio"" menu, select ""Full Processing Mode"".
From the ""Audio"" menu, select ""Volume"", check the ""Adjust volume
of audio channels"" option, and you
can use the slider to change the
level of audio.
Press the ""Preview Output"" button and listen to the audio - if it
isn't loud enough, go back to the
previous step and increase the
amplification level.
From the ""Audio"" menu, select ""Compression"" and select ""MPEG
Layer-3"" and the same or lower
bitrate/attributes (eg. 128 kBit/s,
48000 Hz, Stereo) you used earlier
to make the DivX movie.
From the ""File"" menu, select ""Save AVI"" to save the AVI to include the
normalized audio. This shouldn't
take too long as only the audio is
re-encoded/compressed - the video
will be left alone."

VLC enables you to increase the volume up to 400% by holding down CTRL + UP ARROW.

"If input file contain multiple streams you can use -map parameter of ffmpeg along with -vol :

ffmpeg -i inputfile -map 0:v -map 0:a -vol 1024 outputfile

Note that -vol 256 is equal to unchanged"
