Stereo FIR filter to perform crosstalk cancellation.

in RTcmix/insts/std

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.

Param Field Parameter Units Dynamic Optional Notes
p0 output start time seconds no no  
p1 input start time seconds no no  
p2 duration seconds no no  
p3 amplitude multiplier relative multiplier of input signal yes no  
p4 crosstalk amplitude multipler - yes no  

Parameters labled as Dynamic can receive dynamic updates from a table or real-time control source.

HOLO is a simulation of the fun Carver Sonic Hologram Generator (yeah, we grew up in the late 70’s…). It performs crosstalk cancellation across the two outputs of a stereo signal (as produced by a pair of stereo speakers).

Usage Notes

Try it out to see how it affects the stereo ‘image’. It can be used to create the sense of a wide stereo field. A good use of this is as a follow-up instrument (in the signal path) after any reverb, room simulator, or sound placement instrument. Note that it does not work well with headphones.

HOLO only operates on stereo input files and only writes stereo output files.

Sample Scores

very basic:

   rtsetparams(44100, 2)


   HOLO(0, 0, 7.8, 0.7, 0.5)
