Can I improve my Besweet command line for very low bitrate mp3 encoding?

[Mentalmummy]

I am trying to achieve the best low bitrate mp3 using BeSweet to play as the soundtrack for an avi in SmartMovie on the N-gage. My current command line is:

C:\AVI\besweet\BeSweet.exe -core( -input C:\AVI\video_data\video.wav -output c:\AVI\dvdrip\audio.mp3 ) -boost( /b2=12 /y ) -lame( --priority 2 -h --resample 24000 -m m -b 16 )

and works fine but a bit hissy and with occasional odd sounds.

I understand at such a low bitrate it can`t be perfect but as I am not brilliant with BeSweet I was hoping that someone here could recommend any changes to my commandline that may improve the quality such as reducing the hiss?

I`ve gone for such a low bitrate as I was using 24 as the bitrate but by lowering it to 16 and adjusting my video encoder settings I have got the frame rate up from the recommended 12 to 15 to a much smoother 20 which on a phone is nice and smooth.

Any help is appreciated :)

Does the thing support variable bitrate MP3? Have you checked out hydrogenaudio.org?

I think it supports vbr, I hadn`t thought of that as I expected such low bitrate to not make much difference using vbr.

And no I haven`t heard of the site you mention, will look into that :)

You might also want to consider resampling even down to 11kHz, and use SSRC to do the resampling. I don't know how good the speaker is in NGage, but 11kHz might be enough.
