Dear List, HDF is simple compiler for writing uniform rate data flow graphs.
"Berlin 1977" in "HDF 2006". > let clock_rate = 9 > clock_time = 1 / clock_rate > clock = impulse clock_rate 0 > tr = trigger clock > note = sequ 0 [55,60,63,62,60,67,63,58] tr > tr_16 = pulse_divider tr 16 0 > note' = sequ 1 [-12,-7,-5,0,2,5] tr_16 + note > freq = midi_cps note' > env = decay2 clock (0.05 * clock_time) (2 * clock_time) > amp = env * 0.1 + 0.02 > filt = env * (sin_osc 0.17 0 * 800) + 1400 > pw = sin_osc (mce2 0.08 0.09) 0 * 0.45 + 0.5 > s = lf_pulse freq 0 pw * amp > in out (comb_n [0,1] 0.2 (rlpf s filt 0.15) (mce2 0.2 0.17) 1.5) HDF generates C code. HDF graphs can be dynamically loaded into a running SuperCollider unit generator, or into a running JACK process. HDF is announced (belatedly) because it may be a useful starting point for writing either: - a SuperCollider-like notation for FAUST - a SuperCollider unit generator that dynamically loads FAUST graphs Archive: http://rd.slavepianos.org/t/hdf RDL: http://rd.slavepianos.org/sw/sc3-rdu/help/rdl.help.lhs Regards, Rohan -- Read the whole topic here: Haskell Art: http://lurk.org/r/topic/2Jza8xyMjQXL5I2kk2SBF8 To leave Haskell Art, email haskell-...@group.lurk.org with the following email subject: unsubscribe
