How do I set 24kbps 22khz mono?

[junglemike]

Hi everyone.
I'm trying to encode DVD movie to played on palm handheld and i can't figure out audio settings. I'm using GordianKnot, In audio settings i have this window:

Since palm is slow device and I have to put full movie on 128mb sd-card,
i need to set audio to 24kbps 22khz mono or 48kbps 44khz mono or even 16kbps 11khz mono.
When i try to put there 24 in bitrate field - After encoding audio is downsampled to 8khz - which is inacceptable. How do i force it NOT to downsample and set frequency to 24 or 48kbps? And make it mono?
Can you help me guys?

Check "MP3, custom Parameters (Experts)" and write this in "Lame":

-h --cbr -b 24 --resample 22

resample makes Lame downsample the output file to a specified frequency (22khz in this case). Should work this way.

Note: I would advise you to use ABR instead of CBR

[junglemike]

-h --cbr -b 24 --resample 22
I tried this option, as a result besweet crashes - closes immedately. Without "resample" option it works - but gives me an completely garbed sound. I have read a lame readme and tried all combinations i could imagine with or without a fillowing settings:
"-m m"
-h
--cbr
-b 24
-b 32

And i'm still out of luck. Can anobody help?
Also what do i need to write in the Azid field above Lame? is "-c normal" OK?

Why don't you try "GoldWave" then? It uses lame to encode mp3 and
should work in your case.

LAME is a lousy encoder for bitrates below 128kb/s. My advice is transcode the AC3 (Foobar2000) to WAV and then encode to 24kb/s using a Fraunhofer Mp3 codec. Mp3enc3.1 is probably the best.

I am not sure about it, specially if you want to encode in mono.
