I recently started working with Blu-ray.

Input: 24-bit DTS-HD MA / Dolby TrueHD
Expected output: 24-bit WAV (PCM)
Default output: 16-bit WAV (PCM)

I agree with Porcus that FFmpeg is an invaluable tool. I use it every single day.
But you gotta admit that some design choices are retarded.
:))
Please tell me that at least adds dithering

Nope.
Code: [Select]
sox -r44.1k -n -b24 input.wav synth 10 sin 1k norm -90 dither
sox input.wav -b16 sox.wav
ffmpeg -i input.wav ffmpeg.wav
(ffmpeg version 4.4.2-0ubuntu0.22.04.1)

We need some "fflossless" command that invokes ffmpeg and does The Right ThingTM. Which is to preserve losslessness when it can and err out otherwise.

This is like when a certain Microsoft application did ANOVA and returned negative variances.

The good thing is CUETools shows the speed for easy comparisons.

Where is the speed shown? I don't see it in the log output?
