#24 Isochronic Pulses make clicks

[Polzin]

Isochronic Pulses and Alt Isochronic Pulses make tick sounds that are probably lowering the effect. There is an envelope to limit the effect, but somehow it is not working properly. I had some improvement in reducing the clicks with:

BinuaralBeat.c

   #define max(a,b) (a)>(b)?(a):(b)
   //cur_beatfreq_data is used arbitrarily as a Modulator here (to reduce harmonics in transition between on and off pulses)
   if ((BB_Voice[voice].cur_beatfreq_phaseenvelope +=
        max(1.5/BB_Voice[voice].cur_beatfreq_phasesamplecount_start,
            .0005)) > 1)

For low beat frequency, the increase of the enevelope is much slower, but for higher beat frequencies, it still reaches 1 at 80% of the phase.
For higher frequencies the effect is still noticeable. I am no expert in psychoacustics, but possibly a kind of exponential function for the envelope could be a better idea.

Are you still interested in such improvements and suggestions?
Do you have a better idea for the problem?
