Cool, I assumed there'd be many techniques out there. Do any of you know the advantages and disadvantages between "/oversampling + filtering/" and the other techniques?
adventage : -easy to implement -any waveform can be bandlimited (including sample). disadvantage : -can be very slow. for a classic saw by example, there is an infinity of harmonic, of amplitude decreasing by 6dB/Octave. if you have a perfect filter and wish 60dB S/N ration (that is not a lot), you need 10 octave between the oscillator frequency and (oversample samplerate)/2. i.e : oversample by 512, for a 10Khz saw at SR 44100Hz. cheers c

Yes, I'm thinking about oscillators mostly. thanks _______________________________________________ Pd-list@lists.iem.at <mailto:Pd-list@lists.iem.at> mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list@lists.iem.at <mailto:Pd-list@lists.iem.at> mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
