Transistor vocoder?

Hello, last night i was experimenting with my breadboard, and i came up with an idea, transistors have a supply voltage, which the small voltage controls pitch and volume. but i thought what if i had voice coming in to the supply voltage part(after being super amplified) and the keyboard comes in the control voltage side, would the keyboard not control pitch of voice, while voice modulates? thanks for your help.

Vocoder on the Behringer virtualizer pro?

Hey i have the Virtualizer Pro by Behringer and it says it has vocoder and i just can't figure out how that works...is there any setup or anything to get it to work? i know what a vocoder is and how it works but this is just plain not working? thank you.

Can a ring modulator be used to achieve a vocoder or talkbox effect? Answered

Using a microphone as one input and a keyboard on the other input of a ring modulator.

Voice changers

I know voice changers have been done, but theres only 2 instructables for some rather simple changers and other forum queries are quite old. What I'm looking for is a diy, real time voice changer circuit that can alter pitch and modulation, preferably with pots for fine tuning rather than presets, hopefully without the tinny sound I hear from the majority of samples I've listened to. An amped output with volume control would be cool too to overpower the users voice a bit easier. I'm looking for an output akin to this as an ideal. https://www.youtube.com/watch?v=Dqr5K0K4wL4 I'm no stranger to micro electronics, I can read codes and, with a little review, understand gates and ICs but still have no clue how to design my own circuits to do more than flipflop and turn things on and off. Any ideas ? Kits, DIY plans etc ? Simple and portable is better, want to incorporate it into a costume.

Building a sound visualizer, modulating video with audio?

Hello! I want to build an (analog) sound visualizer. I've already read about building a simple oscilloscope (https://www.instructables.com/id/Music-Visualizer-oscilloscope/) but I want to make something more complex, if this is possible. I want to build a sound visualizer that makes psychedelic stuff from audio. Like the sound's frequency modulates the video's frequency, and the sound's volume (amplitude) controls the video's volume (like how much light is created). How could I build something like this? Just playing sound through a video screen won't work because there is a huge difference in wavelenght.  Do I need to build a vocoder (video=carrier, sound=modulator), like with an audio vocoder? I know alot of stuff about audio and audio electronics, however I don't know much about video and video electronics. All help is appreciated!

Weird and wacky electric sounds (theremin, vocoder etc.)

Anyone know of any really cool sounds you can make with electronics?I'm thinking of making both a Theremin (http://en.wikipedia.org/wiki/Theremin) and a Vocoder (http://en.wikipedia.org/wiki/Vocoder), the first of which seems like a relatively simple circuit, the second seems much harder.there are a few wiring diagrams on the 'net for a theremin, there's links on the wikipedia page (check http://home.att.net/~theremin1/). and you can also buy kits at some electronics shops.vocoder seems like it must be a load harder, and I haven't been able to find any wiring diagrams, and as far as I know, there aren't any kits available. there's a demo of what it does at http://www.sirlab.de/linux/download_vocoder.htmljust wondering if anyone has experience with either of these weird and wonderful devices, either using them or making them, or if anyone has any other strange sound makers that should be brought to public attention?hrrmm... wonder how hard it would be to turn that old evolution MK-149 into one of these http://www.gizmag.com.au/go/5091/ ?

Where can a total beginner go to get learn electronics and schematics specifically with audio projects in mind? Answered

I'd really like to get into the electronic side of music, but have no idea where to start. Some of the projects here are very interesting, particularly those that have to do with sound creation and modulation. My end goal is to be able to design my own circuits for analog amps, guitar pedals, and perhaps even synthesizers and vocoders. However, for now I don't have any idea of how electronics work, nor where to start. I've been told that kits might help, but does anybody have any specific places to start? I'd love to learn basic electronic theory, but especially how certain components create or change sounds. Thanks!

Kaossilator fix?

So, my Kaossilator suddenly dies one day, the power was too high. i have no experience whatsoever with digital so i am lost. Any way to fix this? it was over-exposed to voltage, the voltage suddenly jumped and it went. any fix?

Transistor voice modulation?

Alright, i know now that there is a way to modulate your voice from putting signal in on the voltage pin of a transistor, and controlling it with a synth into the input voltage. But now, what is that effect? and what is a way to smooth out or get clean sounds from it? Any help is appreciated. Thank you.

Guitar wah pedal?

Question, I would like to build a simple wah circuit, and i looked in Tonepad.com and it gave one result but the circuit was a distortion pedal, it was weird, but anyways, ive heard that wah's are easy to build the circuit but the build is hard, the pedal part. sooo any circuits anyone knows of? thank you!!!
