Undocumented option switches: eac3to

[kypec]

eac3to (http://forum.doom9.org/showthread.php?t=125966) is a mighty tool with many features. It has lot of options but not all of them are mentioned in the help included. Sometimes there is a need to modify behaviour or output file format slightly to better suit our purpose. Here comes a few (there might be more yet unrevealed) options, which I found very useful for what I wanted to achieve: (:thanks: madshi for thorough explanation)

-simple
Forces the output WAV file to have compatible (old style Lossless PCM) header instead of modern WAVE_FORMAT_EXTENSIBLE (http://www.microsoft.com/whdc/device/audio/multichaud.mspx). Not recommended for multi-channel files. Mono and stereo files produced with this switch are just fine and can be processed by some older tools, which have no support for modern type header like for example this RMS normalizer (http://savannah.nongnu.org/download/normalize/normalize-0.7.7-win32.zip).
-full
Prevents the output's WAV file bitdepth to be downconverted from 64 to 24-bits. Useful when you require 32-bit float precision for further processing of such WAV files.

If you do a search in "changelog.txt" for "undocumented" you may find a few more... ;)

And many more with strings.exe/hex editor/ProcessExplorer. ;)

Yeah, thanks for reminder. Unfortunately, in your changelog.txt is only mentioned undocumented *** switch added without any detailed explanation how it works, whether it affects input or output and so on. Hardly helpful to anyone except you as the author of the program :(
BTW, those two switches I explained are not mentioned therein at all, therefore I started this thread -> to help other users and keep notes for my reference in the future.

@Snowknight26: Though you put a smilie in the end I must say -> you can't be serious to look for help/features of an application by inspecting it through ProcessExplorer and locating every possible string there is. It might be fun for someone but no way of sharing knowledge between author and users of his product! :eek:

Well, they are classified as undocumented. :p

[kypec]

Well, I think they shouldn't be. It's not like some debug/cheat codes for commercial product/game. They're perfectly legitimate and have proven its usefulness for experienced users. I just don't get it why madshi is hiding them from the rest of the world :(
