BeHappy ac3-->mp3 why mono?

[talkto_menow]

I'm trying to transcode ac3 audio to mp3 using BeHappy (DirectShowSource). I set Lame encoder to CBR 224. Everything seems to be set correctly, however the resulting file has only one mono channel.

Do I have to enter additional CLI arguments? or make other changes?

Here is a new twist

I opened source file using VirtualDub and under file info audio specs says 6 channel AC3.

Than I opened the same file through avisynth option in VirtualDubMod and audio info is PCM Wav 2 channels.

In BeHappy - when opening avi file using DirectShowSource

only 1 channel is recognized and converted to mono

In BeHappy - when opening avs script (AviSource)

2 channels are recognized and converted to stereo

Hi,

You can use Nicac3source as input filter contained in http://nic.dnsalias.com/NicAudio.zip , works in Behappy

if you feed the directshow decoder a 6ch ac3 file but said decoder is set to downmix to 2ch, then opening an avs file consisting of "directshowsource("6ch.ac3")" will result in a 2ch PCM file.

Thanks for your help :)

Setting downmix to stereo in BeHappy worked pefrectly.

Now only problem is setting the right level of gain. 15db seems to the right number, however I wonder should I also use normalization in a process?
