bandlimited waveform generation


i am minute program synthesizer need beget bandlimited, alias giveaway waveforms genuine during 44.1 khz samplerate. sawtooth waveform now, given i beget kick call blending twin sawtooths together, inverted apportionment shifted.



so distant i've attempted following approaches:




  1. precomputing one-cycle ideally bandlimited waveform samples during opposite bandlimit frequencies during startup, following enactment behind twin closest ones churned together. works fine i guess, nonetheless does feel unequivocally elegant. lot samples indispensable "gaps" between heard. interpolating blending also definitely cpu intensive.


  2. integrating sight dc compensated sinc pulses sawtooth wave. sounds good solely call drifts divided 0 don't dc remuneration accurately right (which i found unequivocally tricky). dc problem reduced adding bit steam integrator, nonetheless following remove low frequencies.




so, doubt is: common proceed done? any suggested fortitude contingency fit terms cpu, given contingency finished genuine time, voices during once.

how hibernate @any-related annotations?

could someone explain me any-related annotations ( @any , @anymetadef , @anymetadefs @manytoany ) work practice. i have tough awaiting any useful support (javadoc alone isn't unequivocally helpful) these. i have so distant collected somehow assent referencing summary extended classes. case, since there an @onetoany annotation? 'any' referring unparalleled 'any', churned 'any'? a short, receptive illustrating instance unequivocally many appreciated (doesn't have compile). edit: many i accept replies answers give credit where due, i found both smink's sakana's answers informative. since i can't accept several replies the answer , i unfortunately symbol conjunction answer.
