BTW, if you play with PC you can use Ac3Filter with a dynamic DRC function, or you can recode the audio with BeLight with a Boost function.

I wish my receiver had a "night mode". Even some of the new receivers out there are retarded about the signal processing options. My father just bought a new Denon receiver that sucks. There are a bazillion useless ways to screw with the EQ, all of which make the sound worse, and no way to process dynamic range.

At any rate, no worries. I just have an ac3 audio track that I have since deleted the source material for. I encoded it with a Film Light DRC setting and decided that Film Standard would be preferrable. It isn't worth transcoding to change it though.

Are mono audio files still not supported? I'm trying to rip a mono audio file that is in thd to a dts. Does anyone know how to do this if eac3to can't?

kalston · 17th January 2012, 11:55

I converted a mono DTS file to FLAC without any problem.

An IP BreAKDoWN · 17th January 2012, 18:06

How about a mono THD to DTS (FLAC, or WAV for that matter)?

I can't remember the specifics of whether surecode supports mono dts encoding or not, assuming you even have this $250 codec setup in your eac3to. Try converting to wav first and then to dts. See if it works then.

More likely your eac3to is not setup to properly decode or encode dts. Type eac3to -test at the command prompt and see what it says.

I could ask why you are trying to make a mono dts file...

Stereo acoustics will sound much better, even if you are just duplicating the mono track.

If you are determined to work with this challenging format (due to commercial copyright issues), you can play around with this brand new experimental open source dts codec that folks here have been working on.

I can't get eac3to to downconvert a 3 channel [L/R/C] DTS audio stream. Using -down2 switch does not solve it. The output is still 3 channels.

Yes I have Surecode, it set me back but I have it installed. The reason I'm trying to convert to mono is because the source is mono in THD format.

Here is that command you told me to use:

I would like to try the experimental version, however I can't get the wav so I'm stuck till I can get the wav.

b66pak · 19th January 2012, 20:27

first you need to demux the thd from the m2ts:

Code:

eac3to 00001.m2ts 4:japanese.thd

get the latest ffmpeg...and use this:

Code:

ffmpeg -i japanese.thd japanese.wav

_

An IP BreAKDoWN · 20th January 2012, 07:36

@b66pak Thanks that worked. Except the eac3to complained about it being mono on the conversion from wav to dts, however I used the SureCode GUI and that worked! Thanks again!

As far as i remember, with this command line you'll be obtain 16-bit PCM always, even if TrueHD is 24-bit.
You need:

Code:

ffmpeg -i input.thd -acodec pcm_s24le output.wav

and then, if you need it, you can check the true bitdepth in audioeditor or by -analyzebitdepth in eac3to:

Code:

eac3to input.wav -analyzebitdepth

Thats very useful thanks!

One question though, how can I find the bit depth of the THD since the libav in eac3to can't open it since its a mono?

If eac3to isn't able to decode lossless-stream, then it can't check his bitdepth, so in this case -analyzebitdepth doesn't work.

Right, do you know a program that can analyze the bit depth in THD format?

Please try to follow the provided instructions. First, b66pak's:

Code:

eac3to 00001.m2ts 4:japanese.thd

japanese.thd becomes input.thd in TDiTP_'s instructions:

Code:

ffmpeg -i input.thd -acodec pcm_s24le output.wav

So here, the TrueHD file is now 24-bit PCM in WAV…

Code:

eac3to input.wav -analyzebitdepth

…thus the old, buggy libavcodec TrueHD decoder is no longer involved.

i know only eac3to with his -analyzebitdepth. This command can be applied to any lossless-stream or PCM (in WAV/W64).
BTW, BDInfo can check bitdepth of THD incorrectly: look known issues.
Of course, if libav of eac3to can't decode THD, then -analyzebitdepth does not make sense (because for determine bitdepth you need to decode). In this case you should try fresh ffmpeg.

I've been using eac3to to join various audio files together. I have been doing it by hand as a commandline and it works well.
However I have a directory containing 37 mp3 files (all same params) that I want to join. A batch file would be nice, perhaps using IN DO, but my brain won't work, please somebody take pity...
Thanks.

Thanks.

>.< multiple file batching can be the morning-coffee-buzzkill.

I really haven't done anything like joining files in eac3to, but I do do some batch files.

For doing multiple files, I just open a text file with the "eac3to" commands, copy and paste them several times.
Going back and modifying only the input/output file names.
And then exit at the very bottom.

Note: I also have windows configured to open CMD in a folder, using the context menu: "Open Comand Promt here"

Code:

"path\eac3to.exe" "sourcefile[+sourcefile2]" [trackno:] "[destfile|stdout]" [-options]
"path\eac3to.exe" "sourcefile[+sourcefile2]" [trackno:] "[destfile|stdout]" [-options]
"path\eac3to.exe" "sourcefile[+sourcefile2]" [trackno:] "[destfile|stdout]" [-options]
exit

Then I just copy/paste that into the CMD of the destination folder.
I use "" if the path of my eac3to is in a folder with 2 words including a space "App Bin", and also some of the source files are in folders that contain spaces as well.

I also add in custom logs.

Code:

-log=custom_name_codec__etc_with_no_spaces_to_reduce_amount_of_quotes.txt

As for creating a batch script, I'm not that far in batching.
Yet

Floatingshed · 26th January 2012, 03:06

OK. I've done it. I'm not a whizz at programming so it may not be very elegant but it works. If you want to use it just copy and paste into a batch file (set path to eac3to). Drop into a folder of mp3 files, double click and a single file of them all nicely joined will appear!

Code:

FOR %%a IN (*.mp3) DO echo/|set /p =" "%%~NXa"+" + >> temp.txt
set /p inlist= <temp.txt
set newlist=%inlist:~0,-1%
path.to\eac3to.exe" %newlist% "Joined mp3 files.mp3"
del temp.txt

Hi.

Does anybody know how to set SoX to handle the 64 floating point output from eac3to?
Or in an other question, what kind of 64bit-Stream is eac3to giving out?
I've tried a lot of commands but all I've got is noise and it sounds like playing a CD-ROM in an audio-player.

This is the last command-line i've tried to pipe from eac3to to SoX:

Code:

eac3to "test.ac3" stdout.wav -full -simple | sox -V3 --type .f64 --rate 48000 --encoding floating-point --bits 64 --channels 6 --ignore-length - -t wav --encoding floating-point --bits 32 result.wav

"--type raw --rate 48000 --encoding floating-point --bits 64 --channels 6" -> Doesn't works too. Lot of noise.

If i set "--type" to wav, SoX says:

Code:

sox WARN wav: wave header missing FmtExt chunk
sox FAIL formats: can't open input  `-': Sorry, don't understand .wav size

And if I command eac3to to write the 64bit output directly to a WAV-File, Mediainfo means:

Code:

General
