After listening on headphones I have to correct myself: the allpass filter alone can make a significant difference in the sound. I think that for some reason it's different on the speakers though - maybe because of the bass reproduction.
I just did two videos on phasers and had to talk about allpass filtering by extension. In the first video I mention how moving the cutoff of the allpass changes the phase of a waveform as you showed here in your video too. I go on to show how moving the cutoff quickly is akin to phase modulation which you’ll recognize as the technique used in most FM synthesizers. So allpass filtering can produce sounds similar to FM. Now if you can hear a significant change in the sound without variable phase modulation then maybe that’s your ear hearing the difference in “current”. Like when you enable a polarity flip a kick. In the flipped version the attack of the waveform has the speaker diaphragm moving away from your eardrum instead of towards it or vice versa, whichever the case may be.
You're right about the stages, check out wikipedia article on phasing, and thank you for this tutorial also if anyone is still in doubt for more stages just add more all pass filters ;p
That was really cool and a great demonstration! I actually didn't hear that much of a difference from the allpass filtering alone in my headphones, maybe a slight lowpass effect. I think the plugin is actually 4 separate allpass filters each with 4 poles (I'm not savvy enough, but I think the poles allow the feedback capability).
Thanks! I think you're right about the poles. Unfrotunately I couldn't find any other standalone allpass filter. I know there's one in every Phaser, and also often inside reverb units, but not much of these can be found alone.
15:27 Good point about how the allpass filters don't make much of a difference when targeting higher frequencies. The objective is to RESHAPE the wave via phase. After all, it's the reshaping that's changing the output of the transfer function (distortion). The MOST reshaping is going to happen at the fundamental, and then less so the further up the harmonic series you go. This came as a surprise to me in my own experiments, but completely makes sense. I wish I pointed that out while going over this trick in my video on it. Luckily I have a few more phasers to cover so I'll have to mention it next time!
Can u explain me that if phases of freq below the cuttoff are changed then how much are they changed? Do they go from 0 to 90 or its random? Does this happen same to all freq below cuttoff or phase change is different for all freq below the cuttoff?
I am afraid it's not, but you can use a phaser plug-in in all wet mode to get a similar result - if you disable LFO and manually control the modulation depth you should be able to get very close results. This works because a phaser uses an all-pass filter internally to create uneven phase cancellation on the input signal.
Hi! My main idea is to make it wavetable. What I mean is that you can draw a couple of diffrent waveshapes and morph between them. I found that a couple years ago but I can't program...
Yes, there was talk of adding a timeline, so that it would be possible to morph between multiple waveshapes over time. There is an issue open for this :)

I'm not kidding I think if you add more it does give you more stages****
You did it again, Toby. Well done. I've never known what the all pass filter did.
Awesome! Thank you very much for a nice demonstration and explaining. Very helpful!
Awesome 💪💪
Brilliant!

4:15 beeeeeeeeep
wonderful
Crunchy bass. Interesting topic 😎
Did you get a green screen? Your background separation seems to be improved!
Brylie Christopher Oxley No green screen yet, but I've used some extra processing to make it better :)
check out the tunefish 4 synth

Do you perhaps know of any allpass filters for windows? Would help a lot !
I haven't used this one, but it seems like it'lll do the trick:
www.airwindows.com/phasenudge-vst/
Open-source of course :D
Is this all pass plugin available for windows?

@@unfa00 i might have found a windows port afterall!
@@boimesa8190 Where? :D
@@unfa00 haha shit my browser doesn't save history... Oops
Can I contact the developer of this waveshaper plugin? I have some interesting ideas to it.
BTW Amazing tutorial!
Hi! I'm the developer :p What are your ideas?
Novie Sure! You can file issues proposing your feature ideas on GitHub - Patrick will reply to you :)
