I'm trying to figure out the best settings for AC3->Mp3 encoding in Besweet.
I would like to achieve the highest possible volume without distorting the sound.
Hope someone in here will be able to help me.

//Thanx in advance

My current settings are as shown on the screenshots.

Screenshot of settings in GordianKnot. Since it's the app I use for Ripping:


The corresponding settings in BeSweet:

Well, here's the batch file I used to process the audio of the movie Robocop a week or two ago. I changed the MP3 encoding part to suit your needs.

To execute this batch, you will need, in the same folder as your AC3 file:
1) AZID (included with BeSweet, I think... ?). I renamed the executable AZID.EXE for my own reasons a while ago.
2) WaveGain. WAVEGAIN.EXE in my batch.
3) Naoki Shibata's SSRC "fast and high quality sampling rate converter. SSRC.EXE in my batch.
4) Lame 3.90.3, available right here. Named LAME3903.EXE by me.
5) The batch file below (copy and paste into a text editor such as Notepad and save with a filename such as AUDIO.BAT in the same folder as the executables and your AC3 file).

I recommend using MP3Gain after encoding to MP3 to see if you can raise the volume by another 1.5 or 3dB without clipping.

You might wanna use dynamic compression to boost the volume, otherwise it might be really low. I usually use Normal or Heavy compression at the Azid1 section. If you get distortion, you also might wanna use the normalize function there (which results in a 2pass conversion) instead of hybridgain.

In my experience the Boost function will clip heavily, no matter what you do, so i wouldn't recommend it.

Thanx so much for reply guys
I guess I'll try using HEAVY Dynamic Compression since I already use NORMAL.
