Hi folks, 

just a quick and hopefully easy question: What tool is there for Linux/JACK to 
do measurements of audio interface performance, comparable to what RightMark 
Audio Analyzer does? I'd like to measure data as displayed on

        http://av.watch.impress.co.jp/docs/20080728/44k.htm

(at best a comparable methodology since RMAA seems to be some kind of standard 
for this).

Of course I can generate some sine waves & sweeps and write programs to compare 
WAVs, but for sure there is some tool for GNU/Linux that has the procedure 
automated already, right?

Another "of course": Of course, I'd like the computed spectral data not only 
pictures but also as plain (ASCII) data, p.ex. to be able to subtract spectra 
to determine what a microphone does on its own before entering a specific 
preamp.


Alrighty then,

Thomas

PS: And if you have used that program already, I'd be interested in comparing 
performance measurements of my low-grade stuff with your high-end gear;-)
