At least one board for me, please!
...and I have time to wait for "the perfect" vokoder. |

| This is very exciting. I would be interested in two boards. |

+1. By the time it's ready, I might be qualified to build it. 
Huge vocoder fan,

| Btw. Jürgen, how do you plan to do the frequency spreading? Like usul vocoders voice optimized or also possible to do the bands equally spreaded for musical use? |

Similar to the prototype I built some years ago. To get these wonderfull "ahh" and "ohh" choirs.

In modular DIY projects it's often possible to place the PCB either parallel or perpendicular to the front panel, depending on how much space you have behind the panel. Personally I'm a fan of quite flat modules, even if it can end up more cumbersome to build.
I'm not sure what PCB size you are planning for the vocoder, but it would be really nice if it would also fit parallel to the front panel, and not necessarily need a really deep rack enclosure. The PCB area will be quite big, so I'd expect it would probably need to be split in half... which might not be a very popular wish, and probably too late already.  But still, it is a design choice that might be worth it, considering what kind of constructions people will be using it for. As I will be restoring a big Serge system with one panel missing, I immediately thought about the possibility of building a Living Vocoder in a Serge format, to make the system complete. Another use case would be in a Buchla system, which is almost the same unit size. They both use 4HE module height, roughly 19" width, in a quite shallow box (6½ cm for the Serge). If you would keep the PCB size(s) under 42 x 17 cm, possible with two PCBs in a sandwich, it would fit into a Serge-sized unit. Users of Serge & Buchla would have a great new module to desperately want for christmas, as would the ones of us who like to have our electronics compact & flat under the front panel.
I hope all is well with you, no rush with the DIY project of our wildest dreams. |

The board will be something like 40cm x 30cm.
Forget about integrating this into anything else - you'll want to have this standalone, and you'll *need* a dedicated power supply for this.

That will be one HUGE board! Looking forward to it!

Will the PSU be included on board, as your other projects?
Thank you!

Goodness!
My cute wooden box that I plan to use is just 25cm x 35cm, so I'll seriously consider breaking it in half anyway. At least until I see it. |

What I have routed so far, is as densely populated as some of my usual 16 x 10 cm PCBs - I was "fighting" for every mounting hole.
After routing 2/3 of it, my CAD program started to slow down dramatically, and that's why the project went into a hiatus. Now you have it.
But don't worry, I'll find a solution.
And I promise it will fit into a (deep) 3U 19" enclosure.

Nice. That's the charm of this sport!

Incidentally, my deepest rack unit (only 26 cm) is another vocoder - the Swedish oddball BV-12, built in a few dozens units by Peter Jubel of Clavia & Propellerheads, and one of Florian Schneider's favourites. |

No, u will need a 3x 380v supply,i already did a request at the company,normaly i will have it intalled in my home when the board will be ready. |

damn the 3 phase supply here is only 415v !
board is 40 x 30 !
So glad i decided early on to only work in a not quite 19" format |

Just an idea.
I might be able to put a EMS5000-style vocoder (22 Bands, 8-pole filters) onto that PCB size. Even with much less trimpots than what I'd intended in my original version. Not the fancy stuff like the 5000's frequency shifter etc., but the core, maybe.
I made some simulations in LTSpice, and it looks so promising!
(only 20 BPFs so far, no LPF / HPF yet)

| Wow...sounds like this will be a pretty dense build...Awesome, though! Vocoders are great for so much more than vocal processing, too. |

Splendid!

Very true. This is why I'd prefer spreading the many bands over the whole audio spectrum. Not evenly-spaced, since our hearing is specialized in the voice range, but in a distribution adapted to both a good speech synthesis and a full-range vocoder capability.
In the 22-band EMS5000-style, there are 4 bands per octave in the range of 200-8000 Hz. This is quite extreme, compared to many other vocoders in the 10-16-band range which have 2 or 3 bands per octave. If the 22 bands would instead be used in a 3 band per octave configuration over the midrange, the treble and the bass could have some bands to extend the vocoding capabilities over the full 10-octave audible range.
For instance, this is how 22 bands ("A-V") could be distributed across the 10 octaves:
A B CD EFG HIJ KLM NOP QRS TU V
Band A and B gets one octave each in the bass, bands C and D gets half an octave each, and then the bands are three per octave in the middle, and so on.
Because of the varying bandwidths the sharpness of the filter peaks will have to be a little different between bands, but hopefully it will be worthwhile. It might be the world's first(?) fullrange vocoder, but still with a good voice quality. |

Very hoopy piece of thinking...and makes total sense to me. |
