Spent the weekend breadboarding a substantial part of the vocoder's analogue circuitry.

I didn't want to mess up the "555" on your "thumbs up"!! 😉 Here is your thumbs up. 👍 👍 🙂
are you ever going to get this finished? really want to see what it can do!! love this rackmount audio stuff
What is this going to do?
Could you balance the resistors on the pots to allow a bigger range of adjustment on the pots themselves? Or is this against the point of the vocoder?
A suggestion for the future would be to do the same project using switched capacitor filters such as the LTC1060 or LTC1160 series parts. Years ago I did a project with the predecessor part, the MF10. The part is easy to use and quite versatile.
This is soo nerdy stuff, i love it! 😀
Krispy Kreme. Lol.
hi jullian, can you please record or something output sound? because apparently, mic on your mobile phone or those repros are not wery good.
erm, you've got a long way to go before you offer it to Daft arsed Punks to make a hit record with. lol
PLEASE! Get modern…. Download DipTrace… schematic… PCB…. Send to Elecrow. In the time you could have put a few wires on a breadboard you would have something far prettier and it would be educational at the same time. (And actually relevant!)
time for a pcb?
btw – where do the Krispy Kreme's go in the circuit?
Great video… going to try this myself. Just a odd question how do you find the quality of that breadboard? I like the look of it and may pickup one
Hello, Julian. Is there a fairly simple way of individually notch-filtering all 88 notes of a piano, so that each output can be used to write directly to a MIDI file? I'd like to do it in hardware, or else with some routine on Arduino/ Raspberry Pi, etc. I want to pass an audio signal through a fine-tuneable 'comb filter', then save and edit the resulting MIDI output. If you know of a method, could you please consider making a project video or videos about how it's done? Thanks. P.S. You'll be best off by dumping that breadboard approach, and using a shielded/ground-planed PCB layout, with screened cables between stages. Those microphonics are worrisome hints about future problems.
Super Cool Julian, nice to see the project moving forward.
Maybe you should consider a digital pot arrangement, to allow you to parallel the pots electronically to adjust digitally instead?
