Hello, I'm trying to create an band-limited triangle with 0.25 duty cycle. For that, an approach that I came across uses a band-limited pulse wave with proper DC offset and a 1 pole lowpass (an integrator). Though I understand this conceptually...

Hello, I have a teensy 4.1 whose stereo line out is connected to a mixer, which is connected to (and powered by) a laptop (running on battery) via USB. The teensy is also connected to the same laptop via USB to monitor serial messages...

I'm doing a sweep of level in amplitude(level) of the waveform object. I expected a smooth increase from 0 to 1. However, the amplitude sounds like it is increasing in steps, especially between 0.0 to 0.1 range of input level. Is there a way I...

Variable frequency is not a problem (you can crossfade between wavetables from different octaves), however, the triangle with variable duty cycle that can degenerate to sawtooth-like signal requires approach described here...

Thanks for this! My application however needs a variable frequency and a variable duty cycle triangle. Since the duty cycle is not always 0.5, I can't rely on the inbuilt WAVEFORM_TRIANGLE_VARIABLE, as around 0.0 and 1.0, the aliased frequencies...

Makes sense. What is the easiest way to create an anti-aliased triangle waveform in teensy?

Got it. I am using the audio shield with teensy. A google search revealed that the shield performs anti-aliasing during DAC. In that case, what is the purpose of using using band limited waveforms at all?

I noticed the word ‘BANDLIMIT’ in the names of certain waveforms, but not in the triangle ones. Are they anti aliased?
