Hey hey,
I have just released a new UDO, based on the classic vocoder design this UDO 
uses 11 bandpass filters. The Q or bandwidth is variable, there is a formant 
shift control - by linearly shifting a few of the modulator anaylsis bands. It 
can also be used as a "static" filterbank for either the carrier or the 
modulator. On the modulator the filters will shift with the formant shift 
control. In normal vocoding mode the highest band will either be taken from 
the original modulator or vocoder through internal white noise.

Download:

Demo video:
https://youtu.be/zf0cAVcHCpM
(Note the constant hiss in carrier filterbank mode is corrected now).

Enjoy and best wishes,

Jeanette

Hi Jeanette,

you're so great! Just saw the demo video and I like it very much. Can't 
wait to try your UDO...

Very good work, many thanks!

Best wishes,
Jana

Thanks everyone for the very nice comments. I hope that you can enjoy the 
thing in real life. It sounds like there might be one simple method of 
improving the efficiency. I'm working on it.

Best wishes,

Jeanette

Hello Jeanette,

Thank you for sharing the code. The sound in the demo video is very nice!  I need to analyze your code and will find the reason why my vocoder program sounds poorly.

Thank you. Why does your vocoder sound "poorly"? Too dark, so you can't
really understand the speech? Or to sluggish? Those were issues I had at
first. I changed the default ihp of the balance opcode and I think
either the original highest modulator band or a white noise excitation
helped greatly with that. I really wanted to emulate the Roland VP-330,
but couldn't find centre frequencies for the bands, so I based that on
the MAM VF-11, which funnily I have myself. :)

Best wishes and good hacking,

Jeanette

Hello Jeanette,

Thank you for your comment . The basic logic of my vocoder is similar to yours, but I capture envelope from the modifier(BP filtered) to control the carrier. 
I firstly used RMS to capture the envelope of each band, but the speech is not clear.
When I used FOLLOW instead of RMS, the speech is clearer but it sounds like having aliasing.
I need to investigate the best ihp for RMS patiently. 

I have a Roland SVC-350 but the centre frequencies are not mentioned in the manual.
I’m using the centre frequencies of DoepferA-129. You can check it here: http://www.doepfer.de/a100_man/A1291man.pdf

Regards,
Tetsuya Miwa.

Hey hey,
I have just uplooaded a small efficiency update, many thanks to Steven Yi, for 
pointing out the use of sumarray with a-rate arrays. I hope that it improves 
the realtime efficiency:
