how to encoding DTS-HD MA 7.1 to AC3

[n_response]

hello

I have a question.

I want use eac3to to decode dts-hd ma 7.1 to ac3

nero 7 already installed .

the error message is:

the real long time is 77 mins

but the error message is 4:49:45



E:\AUDIO>eac3to 01.dtshd ac3.ac3 -640
DTS Hi-Res, 5.1 channels, 4:49:45, 24 bits, 1676kbit/s, 48khz
Decoding DTS-HD track to raw. Please wait...
Find sync word: 7ffe8001
Find sync extension: 3f
The file size of the raw file doesn't seem to fit.
The expected file size for 16 bit is 9.32 GB.
The expected file size for 24 bit is 13.98 GB.
The real file size is 4.38 GB.




thanks for the question

how can i do?

You should have posted in the eac3to thread...

eac3to uses sonic decoder for dts files, by default. I guess you have it installed. But either way, sonic outputs up to 6.1 channels.
So, if it works for you it's all right.

I don't know what's wrong with your file/setup. Madshi should know.

You cant decode all 8CH from DTSHD MAS Audio.

eac3to/SonicDecoder output only 5.1 from 7.1 DTSHD
But i think its a proper downmix and the Extra Channels are blended into 5.1

However, youre fine with 6CH for a AC3 reencode..:)

Why you get the Error Message?...I dont know.
Ask in the eac3to Thread

Youre problem comes with the filesize.
WAVs have a header "bug" that restrict their size to 4Gb (it has something to do with 32 bits and the lack of capacity to describe sizes larger than FFFFFFFF (4294967296 bytes = 4Gb)).
Some software (editors, decoders, etc) can't create WAVs bigger than that, no matter what setup the WAV is (2ch, 6ch, 64ch, etc). But others can just ignore that limit and keep outputting the file. Wavewizard is one of these tools with its "Ignore file size in header" option.
You can decode outputting single channels, one at a time, to avoid reaching that 4Gb roof too fast (4Gb can hold 12hs 25min of 1ch/48kHz/16bits audio or 4hs 8min of 1ch/96kHz/24bits audio, so unless you have a very long audio track, that limit is hard to reach). Or as much as stereo, but hardly as 5.1 as the 4Gb limit comes at 2hs 5min for 6ch/48kHz/16bits files and 41min for 6ch/96kHz/24bits files.
Once you've decoded the file into its mono streams, you can remux the streams with wavewizard, using multichannel WAV order (L-R-C-LFE-Ls-Rs) and WAV PCM header (for maximum compatibility with encoders), even if the final file size is bigger than 4Gb.

He wasn't decoding to wav, but raw. So nothing like that.

The problem is solved now. See eac3to thread. He had an ancient eac3to version...
