DTS-HD 24-bit to FLAC 24-bit

[smegolas]

I tried converting a DTS-HD track to FLAC using MeGUI,

it worked fine but the output was 16-bit (and mediainfo shows the runtime as double the original runtime. still plays okay but not ideal)

I want to keep it 24-bit and completely lossless.

The options for the FLAC encoder in MeGUI are pretty limited, I don't see any toggle for bit-depth.

Is it possible to do what I want in MeGUI?

If not, what is a good program to do it? I tried eac3to but too complicated and doesnt seem to have a DTS-HD decoder built in

What program does MeGUI use to convert?

According to medinfo on the encoded file, it uses
libFLAC 1.2.1 (UTC 2007-09-17)
I think I have fixed the double-runtime issue but I am still getting a 16-bit output

What does it use to decode? I'm not worried about the FLAC end of things.

FFAudioSource()

I think maybe my problem is here:

?

Yes, use eac3to and the Arcsoft filter. Does ffmpeg even have a DTS-HD decoder? I think not. Even sometimes with 24 bit audio, it will only give you 16 usable bits, and software like eac3to will detect this and just throw away the empty 8 zeroes.

Okay, will give it a shot.

Thanks
