Audio interface analysis (AD/DA performance, preamp quality)
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;-) signature.asc Description: PGP signature -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
