wavspec - displays the impulse response and spectrum of wave file data.
wavspec without an argument will display impulse response plots and spectrum
plots and write the plots to the files:
\imimp.tif and \imspec.tif
See the variables fontSize, dimLength, and dimWidth to modify the font size
and TIFF dimensions.
wavespec(1) does the above and plays the file:
\SLABData\wavs\sqam_voice_me.wav
followed by the file filtered with each impulse response.
Impulse responses are read from the following wave files:
slabout1.wav, slabout2.wav, slabout3.wav, slabout4.wav
The default .wav's demonstrate slab3d reflection processing.
Acoustic Scene Parameters:
Src = ImpulseFull1024.wav, one-shot, auto-stop
Gain = 20.0 dB
Relative src location = 60 az, 0 el, 0.25m range
Radius = 10cm
Spread = 1 (normal)
Smooth Time = 0ms
Room = depth 4.0m, width 3.0m, height 3.2m
Listener is 1.8288m (6') above floor. (SLABScape LST_HEIGHT)
Perfect reflector walls.
slabout1 = direct
slabout2 = right wall reflection
slabout3 = 1 and 2 together
slabout4 = direct and 6 reflections
Note: This function places several large variables in the global workspace
(see 'whos global'). To clear, 'clear global'.
