Easiest and good way ac3 5.1 to wav?

[tvconfuse]

What is a good/easiest method for converting a ac3 5.1 file into a stereo wave file?

My ac3 5.1 file is very low in volume even with my speakers maxed out. I need to boost the volume in the wave file without clipping/popping and hissing.

The software that I have right now on my computer are:

eac3to
headace
Besweet (belight gui)

What's a good one to use? Is there something better?

A VERY old favorite of mine is the simple to use "PX3CONVERT.EXE"...

eac3to should get the job done just fine. If you have Nero 7 or the Sonic Audio Decoder package installed, you'll even get a decode with a Dolby reference decoder. If not, eac3to will use libav (patched for highest quality output) for decoding which is the next best choice. You can use this command line:

eac3to source.ac3 dest.wav -down2 +5db

The "+5db" will raise volume by 5db. You can increase the volume gain, if the volume is still too low. You might want to double check the final result with a WAV editor (e.g. the free "Audacity") to check whether there was any clipping. eac3to does not yet check for clipping. That's on my to do list for a future version...

I do have nero version 8 installed (I think) but eac3to does not seem to want to use it.

I'm sort of stupid when it comes to this so how much of a volume % increase is the +5DB? 10%? 20%

I assume the -down2 means down sample to 2 channel wave?

As I said, eac3to wants to use Nero 7.

I'm stupid with this stuff, too. Best thing is to just try different numbers to see what gives you the wanted final volume level. Processing should be rather quick, so it's no problem trying different values.

I assume the -down2 means down sample to 2 channel wave?
It means down matrixing to 2 channels. Whether the final result is stored as WAV or in a different format depends on the extension of the destination filename you're choosing.

Audition is not freeware, is it? Furthermore the AC3 filter you linked to is based on liba52, which is not a Dolby reference decoder. JFWIW...

With BeLight you can select the downmix method between plain stereo, Dolby ProLogic or Dolby ProLogic II modes, include or not the LFE channel.

You can also use 2 pass methods to maximize the output without clipping, the Azid 'Maximize' or the OTA options.

thanks for the infos but i knew that all.
Audition is not freeware(just like nero) and the ac3 filter in the link is based on liba52 but he asked for "good/easiest" and not for free tools and this is the good/easiest way that i know.
who knows tvconfuse have Audition and don't know this ac3 filter?!?

i want to do one question of what i really don't know:
eac3to is a Dolby reference decoder?
if yes, i will go now to read the complete thread! :)
thank you!

+3dB --> +41% volume increase.
+5dB --> +78% volume increase.
+6dB --> +100% volume increase.

No, eac3to is just a tool which can make use of either the Sonic or Nero 7 audio decoders (both of which are Dolby reference decoders), if they are installed on the PC. If they're not installed, eac3to uses libav, which is comparable to liba52.
