bass boost with sox

mtb · 08-19-2004, 02:05 PM

I'm creating a script to convert tracked music to ogg, mp3, wave and so on, and i would like to add an option to add a "bass boost" effect using sox.

With bass boost i mean something like the effect avaible with audacity, where the user can choose the freq and the db's gain at this freq.

With sox i see nothing to do so, probably because i'm not a sound expert and it's somewhat "hidden" .

I have tried with a lowpass filter but the result is a lot different from what i would like to perform.

Thank you in advance.

It doesn't look like Sox can do this, unfortunately. I did find nwfiir audio tools, which looks to be capable of equalizing audio. I guess you could also use XMMS with the equalizer, and the disk writer plugin. XMMS with the right plugins can play most tracker formats.

I'll read the entire page about nwfiir, unfortunatly it's highly non-standard and no more developed, but i'll see what i can do with this set of tools. I hoped to use sox

.

I know i can use xmms for example with uade to play most ( amiga ) tracked music, but what i want ( and what i've already done without the bass boost ) is to create a script ( always using uade from command line ) that can produce for example wave files ready for example to be burned on cds .

Thank you!
