Virtualdub does not do this fast as far as I can see.

Can someone give me an awesome pointer since I have some old series (more than a 100 individual avi files) with a soundtrack that can definitely do with quite a bit of bass or graphic equalizer adjustment on the soundtrack. Since it is series of individual files, batch processing is a must.

Do you want to save the changes to the avi files, or just adjust the audio levels while they are playing? – music2myear Nov 23 '11 at 17:00
I want to save the changes to the avi files - so a standard change applied to a series of files. – mm2010 Feb 13 at 8:53

Since you're using AVI you can use the built in equalizers on VLC or WMP12

Your answer does not help me...as I then have to continuously adjust (on replay) if I jump to other series or movies which is a nuisance. IE I am looking for something that can easily re-encode the avi files itself with the adjustment. – mm2010 Nov 23 '11 at 17:02
Would you not have to individually re-encode them? – victoroux Nov 23 '11 at 17:06
Yes, in a batch preferably. – mm2010 Nov 23 '11 at 17:07
You can save equalizer settings... – victoroux Nov 23 '11 at 17:08
On Playback - what then if I copy them elsewhere and use a different media player or give some to someone? – mm2010 Nov 23 '11 at 17:10

Have you looked for EQ or audio manipulation plugins for VirtualDub?

It seems that while VirtualDub by default doesn't support audio plugins, there is a fork hosted at http://www.virtualdub.net that does and there is apparently a filterpack there that you may want to look into. I cannot explore this right now as it's blocked on my work computer.

Look promising - this will take a while (Thanks for the info) – mm2010 Nov 23 '11 at 17:18
I had a look, but it does not seem to do what I want. – mm2010 Nov 23 '11 at 17:29
