[LAU] CLI tools to handle SF2 files?

[Crypto]

Hi,

at the moment swami is the only tool running on linux natively that deals with 
manipulating SF2 files.

My personal SF2 collection has grown over time and it is a pain to find out 
the best presets in each file (I mostly use GM collections of sounds).

I have read about a lib that implements functions to work on SF2 files, but I 
have not found any doc about it. Where can I find the lib and doc for it? If 
there was a CLI tool that uses the lib then I think by using scripts handling 
the SF2 files could be easier. Something that does most if not all things 
that swami does, only that it is run via CLI and a command line.

Looking at SF2 WAV samples I noticed that in most cases they are not 
normalized which results in the old problem of different presets having 
different volume throughout a SF2 file.

This is where I would like something that does normalizing the sample(s) of 
the preset. I know that normalizing tools are out there, it's more a question 
of putting pieces together.

The second problem which is even worse to deal with is looping sounds. I know 
that it is unlikely this could be done automagically, but an option in tools 
such as swami to find zero levels of a sample could already help. Maybe this 
is something for the next release of swami? Or maybe you have other 
suggestions on handling SF2 files?

Kind regards,
Crypto.
