Hey all

I want to make a program which does the following :

- Input audio from sound card line-in
- Get it in raw format (FIFO of the data, xxxx Hz sampling rate x xxxx bit resolution)
- Do some processing which would be suitable to show a matching visualization (so need to be able to run DTFT to obtain the spectrum)

This should be able to run in near real time (no requiring of "proper" real time, just be able to run along with the arriving analog input, not buffering it all for revisit later

This should run on a modern Linux system, where the main sound platform is ALSA, and support for old Linux sound technologies (OSS, etc) might not be available or not work correctly etc

So what i am asking is, what libraries or example code would you recommend me to look into ? - I found several mentions of modules on cpan which use OSS, but i am not sure whether it is supported properly on modern linux, and whether there are any newer and better suited libraries which are not widely known

Best Wishes - Ash
