HOLO -- stereo FIR filter to perform crosstalk cancellation
quick syntax:HOLO(outsk, insk, dur, AMP, XTALKMULT)
CAPITALIZED parameters are pfield-enabled for table or dynamic control (see the maketable or makeconnection scorefile commands). Parameters after the [bracket] are optional and default to 0 unless otherwise noted.
p0 = output start time (seconds) p1 = input start time (seconds) p2 = duration (seconds) p3 = amplitude multiplier (relative multiplier of input signal) p4 = crosstalk amplitude multipler p3 (amplitude) and p4 (crosstalk amplitude multipler) can receive dynamic updates from a table or real-time control source. Author Doug Scott
HOLO is a simulation of the fun Carver Sonic Hologram generator (yeah, we grew up in the late 70's...). It does some monkey-business with phase-cancellation between the two outputs of a stereo signal.
Usage NotesTry it out to see how it affects the stereo 'image'. It can be used to create a very (deceptively) wide stereo field. Psychoacoustics in action!
HOLO only operates on stereo input files and only writes stereo output files.
Sample Scoresvery basic:
rtsetparams(44100, 2) load("HOLO") rtinput("mysoundfile.aiff") HOLO(0, 0, 7.8, 0.7, 0.5)
