It really depends what you're trying to achieve. If you want to equalize PA systems, japa can be helpful, (using pink noise); if want to create freq response plots or measurements, maybe you should patch JAAA to add a log-scale option... maybe you're actually looking for a different tool e.g. http://www.baudline.com/ check the README of japa; it clearly states that it does filtering ("With the default settings, JAPA uses a filter set that closely follows the Bark scale"). Fons - author of JAAA and JAPA - is on this list and may chime in sooner or later. ciao, robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
