Good idea with the random phase
We did pseudo PWM with two identical arbitrary waves, one inverted, but
not what you describe with random phase

Just put them in the buffer with random phases and they'll never re-align.
That's not what a piano does of course, but might be servicable.
BTW, my synth does

the *number* of wavetables gets large, right? is that what you mean?
yes, bad wording
it doesn't have any

Another disadvantage was that you get a noticable chirp transient when
the phases
realign after one complete cycle of the wavetable.
You don't have this in a piano since the phases never realign again
after the initial strike
so you have the transient only at the onset of the note.

Some years ago I tried to make a "stretched partials" sawtooth this way
and found that the tables get prohibitively large
since you are restricted to common devisors or integer multiples for the
"spin cycles"
and phase steps of the partials.
The second lowest partial needs to make at least one
Below is my interpretation of the cool partial-shifting method Robert has
proposed. (I'm just trying to understand, no claim to originality.)
As far as I understand it, the method obtains, from a harmonic waveform, a
family of new waveforms where the partials are selectively pitch-shifted,
but re

Thanks for your friendly comments, Robert!
First of all, I probably need to clarify that I'm not trying to make a
traditional synth application out of these wavetables, but I will use
some of them in my own compositions in one way or another.

There's an open-source wavetable editor:

Hi Frank. I’ve never messed with these, but it seems obvious that they are

they intend to let people sue anything but their own editor), or add/expect
additional info bundled in the wave file (in which case they’d also
I've written a Wavetable Oscillator for my modular software synthesizer.
Surveying the synth software I can find (Serum, XRSDO, etc.) it seems that
they all store wavetables in WAV files, PCM format, which I'm able to read
and use with libsndfile.
However, is there any idea how I can tell how man
19 matches
