Mystery I made demonstration how you can use ReClock to get 432 Hz audio from 440 Hz in realtime. Several rules.
You need to add custom resolution to your display. Different for each source framerate. In video shown example with 25 fps source. You need to check if your audio really 440 Hz base frequiency.
It is needed to use some frequency analyzer. Slowdown can be applicable mainly for instrumental music but not for voice or sounds of nature.
It this case sounds are real when pitch is 1.00x at source speed. Calculations and explanations. 25 fps soucre. Integer mutipliers 2 and 3 gives numbers 50 and 75.
A Clean Audio Conversion Program for Mac and PC. -Having the option to convert to 432hz or 528 Hz. 432HZ folder that you created on your computer and double click on the song and it will play in your iTunes or Media Player and you can put them into a 432 playlist! There you can change the software instrument pitch to 432Hz or other. Mac Book Pro i7, Logic X, MOTU 1248,MOTU 8M, MOTU Monitor 8.
I take 75 Hz and slow down it with 432/440 ratio. I got 75*432/440 = 73,636 Hz.

I used NVIDIA control panel to add this custom resolution (and frequency) to one of my monitors. I allow ReClock to use 3% slowdown. So I got new sample rate in ReClock for 44100 Hz audio: 43296 Hz. Make some test with calculation real ratio: 43296 / 44100 = 0,981769 It is very close to yours 0,981818.
With the above script, some videos play corrupted with SVP. If I disable SVP, then the image shows up fine.
Until I re-open it again. Any idea what could be causing this and how to avoid it? What's also curious is that yesterday I only saw that issue a few times on the TV screen, while right now on my laptop screen it seems to show all videos as corrupt.
Edit: Adding 'ConvertToYV12()' after FFmpegSource2 does solve the problem in 'most' cases. There is still occasional corrupt videos and occasional out of sync audio; where plugging into ffdshow directly would be a better option.

Here's one video that fails Here are the streams I have downloaded Video: MPEG4 Video (H264) 854x480 29.97fps 1082kbps [V: h264 main L3.1, yuv420p, 854x480, 1082 kb/s] Audio: AAC 44100Hz stereo 253kbps [A: SoundHandler (aac lc, 44100 Hz, stereo, 253 kb/s)] When playing through the AVS script, here's how MPC-HC sees the streams Video: I420 854x480 29.97fps [V: rawvideo, yuv420p, 854x480] Audio: IEEE Float 48000Hz stereo 3072kbps [A: pcm_f32le, 48000 Hz, 2 channels, fp32, 3072 kb/s]. It's also worth nothing that without SVP, it appears fine. And adding SVP into the mix is what corrupts it. But perhaps the float audio doesn't help. Not sure how to change it.
On a side note, this setup is actually working pretty well with my software playing the videos one after the other and generating the scripts. Audio/video sync is holding pretty well. When using SVP3. I've been getting weird stuff going on when re-testing SVP4, and I don't want to test 2 new components at the same time. But if SVP starts lagging, then audio/video go off sync.
