Hi!
I'm working on a minBLEP based oscillator. This means that my output signal
will contain all ripple needed for bandlimiting the output after each step.
Other methods of generating bandlimited signals, for instance interpolation in
an oversampled table will produce half of the ripple before
In informal listening tests I found that there is a miniscule audible
difference
between a linear phase and minimum phase transition in a sawtooth wave
when using headphones.
The minimum phase transistion sounded "sharper" or "harder" IIRC.
The difference was barely noticable and possibly even
I played with minBLEPs about 15 years ago, and came to the same conclusion that
I’ve seen many others come to over the years: there’s no significant advantage
to minimum phase in typical synth use. Mainly, you need to have some delay to
line up a minBLEP, and there’s no tangible downside to havi
