ffmpeg … -c:a flac -exact_rice_parameters 1 -multi_dim_quant 1 …
I was encoding wav to flac.
- With default options, the result was almost instant
- At > 500x speed
- Used
-compression_level 12, finished in ~ 7 seconds- speed = 48.9x
- Then I used
multi_dim_quant- After ~ 10 minutes, I checked the speed to be ~ 0.02x. So thought it would take an hour or so. 1.30 seconds worth of audio was encoded
- It’s been over 2 hours now.
- Shows 1.46 seconds of audio encoded with current speed = 0.00017x
Considering running it in a VM, so I can “pause” it whenever I need to restart my computer.
Update:
size= 123KiB time=00:00:02.82 bitrate= 356.3kbits/s speed=4.68e-05x
It stopped trying to use layman notation.
I’ll need to restart soon-ish, but I’ll see how far this goes and if the 2.82 seconds of audio is even listenable.
Or, and hear me out, you could maybe reevaluate whether you really need the very marginal compression improvements offered by multi dimensional quantization.
This try was actually me evaluating the thing.
Now I am considering reevaluating whether evaluating the option is viable for me.

If they give WFH, I’ll sign up.
Yeah, that’s fair.
