Block IO Protocol Media Information | UEFI Dev (in C)
34Printing Block IO Protocol Media Information, to see what disk partitions are returned by UEFI.
Audio Notes:
- Trying a different audio setup in OBS for gain, expander, de-esser, eq, compressor, and limiter.
This video still had noise suppression, but I removed it after this as words are being cut off occasionally. May have to use it when the HVAC is blowing though.
In editing, I'm using izotope elements RX de-click on the whole video with low latency, sensitivity 3-5, and 1-2ms click widening. Trying to be light with processing.
This causes lag in Davinci Resolve until reloading, although lowering the timeline proxy resolution to half or quarter makes playback a bit smoother. A full reload after adding the audio effect makes playback perfect again.
The de-clicker basically automated all of my manual fixes for mouth clicks and similar noises.
Hopefully it didn't degrade the audio signal much, but I am EXTREMELY happy as I don't have to go through and remove clicks on videos anymore.
If it worked live in OBS I would cry tears of joy (they need to allow VST3 plugins!).
I removed all other post audio processing as the OBS recordings should be OK now for audio, but can add stuff back if needed, like normalizing to -18LKFS for youtube if the levels are too low on this.
Overall it should sound more even and clearer, but let me know if you have suggestions or it sounds bad. I may get a channel strip or other hardware setup to replace the OBS VSTs. That way the audio setup would be the same on any operating system or platform, and can use physical knobs for adjustments.
