View Full Version : Audio Gain Problem When Using Gnot

Hi all,

I've got a real strange problem using the audio encoding facility with Gnot. The Strange part is it used to work fine so I must have done something to screw it up but I cannot figure it out.

Here's the details:

I'm encoding an episode of The Prisoner. The audio is mono so I plan to encode a mono mp3. I can't use the BeSweet option as it does not support mono encoded mp3 files so I'm just using azid to create the file (as I've done before)

Azid settings are: -c normal --maximize
lame settings are: --alt preset 80 -m m --scale 1

Usually, I get a great mp3. Now whenever I try this (or anything using azid and not the besweet option) this is what happens:

Azid starts scanning through the ac3 file looking for the max gain. It starts off with a gain of 29.9 db.

After scanning through the ac3 file azid starts to write out the wav file but its still using a gain of 29.9 db!? Regardless of the ac3 file used, the whole maximize process does not seem to work any longer.

The wav file that gets written out has zillions of errors as the gain of 29.9 db causes the sound to spike just about every second. The final mp3 sounds like crap cause the gain is way to high.

Now as I've said I've done this lots before but now azid will only spit out wav files boosted by 29.9 db.

Can anyone suggest what the heck is going on? My maximize seems to be broken!

I think azid version, which comes with GKnot (not besweet's azid.dll), don't support --maximize command. You could try just with:
-c normal

Azid will do a first pass trying to find maximum gain (if you don't especify another gain value) ;)

Well I think I found the problem, though it surprised me.

It was the new version 1.8 of azid I had in the gnot directory. I have the latest besweet files, and the latest version of azid. When i reverted back to the 1.71 version that comes in the Gnot set up package it works fine.

Doesnt that sound strange?
