[linux-audio-dev] Vsound-like tools for ALSA?

[Grubs Nubby]

Hello,

I realize this is a bit belated for the thread, but there are such an 
audio application to convert between file formats.  I admit that I 
haven't used any of them, so bear in mind that I cannot vouch for the 
effectiveness of any of these applications.

SoX
The Swiss Army Knife of sound processing utils. It can convert audio 
files to other popular audio file types and also apply sound effects and 
filters during the conversion.

GNUShoes
A wrapper for the SoX audio utility. Written in Perl for Linux and 
Win32, GNU/Shoes aids the tedious process of converting large numbers of 
audio files, and will soon provide Jabber messages to notify the user 
that a batch is complete.

There are also a few front-end listed on the site as well.
