Changing oscillator waveshapes without a pop

[KnightHill]

Is there a way to change oscillator shapes without making a pop? Ideally, without using two envelopes to gradually morph the signals.

example: from
osc.SetWaveform(Oscillator::WAVE_SIN)
to
osc.SetWaveform(Oscillator::WAVE_TRI)

Thanks

Although @Manysounds was answering a different question I think his post answers your question to a degree, maybe without actually providing code, which would have been even better. I haven’t read the whole thread.

Crackling Loud Noise when changing volume and pitch

You need to smooth your parameter changes over time. What is happening is when you jump from one value to another instantly there is a hard edge on the the waveform = distortion. For example, if you generate a sine wave and then instantly increase it’s volume by 10db, you have created “a piece of a square wave” interjected into the sine and the D->A converter WILL make a click. Do this multiple times a second and it will sound like noise/distortion. Soooooooo it is best to perform parameter cha…

Hmmm, it might help to switch the waveform at a zero crossing.

[Manysounds]

Alternatively you could “fade” from one to the other which might give you a moment of weirdness, but only a few cycles.

That would double the number of oscillators, wouldn’t it?

You’d need twice as many oscillator objects in code, but you wouldn’t have to make double-calls to Process() except during the crossfade… so conceivably the extra CPU load could be manageable.
