upcoming beeper compos (Page 6 of 6)

Hi, guyz!
Yes, invite you to this noisy party, I think it will be interesting to see beeper from other side - not try to make it "nice, melodic", but make it noisy, glitchy, atonal, surreal))

I think I have some appropriate material for this compo

Regarding looping PWM samples, I've got an idea for a design that would be relatively cycle-efficient. We need to check for the end marker anyway, right? If we put a loop pointer immediately after the end marker, that loop pointer could either point to the end marker itself (effectively stopping sample playback) or to some arbitrary position in the sample (actual loop). The only caveat is that the encoder needs to ensure that 1) the phase is not accidentally inverted by the loop, 2) state is 0 at the end of the sample, and maybe 3) the length of the last half-cycle before the end is reduced by 1. This would rule out extending PWM half-cycle length beyond 255, but I think we can live with that since we can pitch down anyway.
