How would this waveform sound?

[Breakdancing Jesus]

Was messing around in multisim trying to create an octave up effect, but then this happened.


The red is the new waveform, while the blue is the original sine wave.

The positive alternation is roughly 10ms shorter than the original sine wave's (@ 82 Hz). The negative alternation is about 10ms longer, and a smaller amplitude. The period is the same as the orignal waveform, but its slightly out of phase. And obviously, the bottum alternation has the ummm, gouge in it.

So what sorta sound do you think this will this make? I'm guessing a slightly buzzier tone, not sure what sort of effect this will have on harmonic frequencies (none?). Can this be developed further into any useful distortion boxes or something.

Perhaps you can let multisim do a frequency analysis on it? Then you'll see which extra frequencies are generated and in what amount.
If you can export the wave into a *.raw file, a tool like Soundforge can open it and play it for you.

I'd guess that waveform would sound a little octave-y, but have some high frequency fizz on top.  Maybe more Scrambler than Foxx Tone Machine.

Looks like a Blade waveform.

Looks like a Blade waveform.

Thanks for the responses guys.

Yea it does look alot like the blade, however your circuit is far more flexible, and I'm not sure exactly what I did besides fail to get one half of the wave form by itself. Hmmmm.

I'll prolly try to develop this idea further and use it with a bandpass filter whos parts I'm currently waiting on. Any ideas would be great.

You can output audio from multisim...

( the links in there don't work anymore but it'll give you the general idea )

I've heard such a waveform a lot and have to say the sound is rude enough with too much cross-over distortion while playing chords or power-chords.
At the same time playing quarts and octaves you can obtain some very impressive "heavy" sounds.
Also such an asymmetric waveform can cause unpleasant "farting" effect. To avoid it reduce bass contents by swapping coupling capacitors with the ones with 3 to 10 times less values.

it is a "blade" wave. I have been studying the formulas for waves recently. It is just flipped over the x axis.

Thanks for all the info guys, especially the multisim stuff.

Hey bass, do you have any links for the waveform stuff you've been studying, I'd be interested in reading up on that.

[bassmasta17]

Well its just sine and cosine manipulation.
for example...
to shift the wave to the left by pi/4 (phase shift)
y= sin(x + pi/ 4)
Its from school so no links but you can find it anywhere on the internet.
take it from there and you can invert, phase shift, amplify and stretch or shrink it. Basic High School stuff.
