Writing this app is inspired by excellent applications written by Fons Adriaensen: http://users.skynet.be/solaris/linuxaudio/ Theoretical background belongs to Angelo Farina: http://pcfarina.eng.unipr.it/ In particular, this method was used: http://pcfarina.eng.unipr.it/Public/Papers/134-AES00.PDF Few hints: - move mouse above "?" sign at plot window and wait, - to delete measurement, use context menu on mesurements table, - to see what the app do, just connect app's JACK ports and try, - to see what your sound card do, use loopback for line in/out, - using "very smooth" fractional octave smoothing is hungry for CPU. So be patient when select more rather 1/3 octave smoothing (1/3 octave and less smoothing is rather interactive). EOF
