Thank you!
I've had a little free time in which to take a crack at this. Here's my
first pass at the "source of juffo-wup" line. It by no means matches perfectly and could use some tweaking but I think it's probably closer than anything else yet submitted.
I have also mixed it into the game dialogue in a similar manner to the files submitted in the bug report (Although the timing is different and therefore will require revised subtitle timing. I have also added chorus tails to the game dialog in order to make it transition smoothly.
Here is a 44.1 kHz version of mycon043 with a chorus tail at the end,
and here is an 11.025kHz version which ends abruptly as does the original file.
The trick to this one was using a chorus effect on top of the reverb. I couldn't identify this on my own but some nice folks at freesound.org suggested this to me and it works beautifully!
I run it through a fairly complicated processing sequence, but I will do my best to describe it here should anyone want to re-create it in the future:
1. Pitch shift dry dialogue to 87.08% of original pitch (-2.4 semitones) while perserving duration
2. Manually pull down peaks that are too loud with volume envelope
3. Compress with a threshold of -44.1 dB and gain up 29.8 dB
4. Apply a low-fi ('bit crush") effect to simulate 14700 hZ, 9 -bit audio - adaptive encoding with 63% antialiasing (this is probably not "accurate" to the original recording but it sounded right)
5. Send a copy of this new "dry" signal to an effects chain containing:
6. A 7 second decay reverb with 1ms delay
7. A chorus effect with an oscillator at 0.82 Hz
8. Another lo-fi "bit crusher" at 11025 Hz, 66% adaptive antialiasing, 10bit sample size (once again just going off sound with my plugin)
These "wet' and "dry" channels are both sent to a -3 dB fader. I also send one syllable of the tail of each original dialogue to the "wet" effects channel and fade its volume up to create a tail.
It would be much easier if you could just look at my Pro Tools session which I would be happy to post, but this is proprietary software using proprietary plugins and i don't think would be of much use to anyone other than professional audio people.
