Re: [ecasound] AAC batch conversion with Ecasound?

Hi,

We are using ecasound for 4 yeras now and love it :)

We have a question :

Our website members are uploading large mp3 audio files days after days on
our servers.
We currently try to convert on the fly these mp3 files once uploaded with
ecasound to aac files

We use this command
for i in mp3/*; do ecasound -i resample,96000,$i -o aac/`basename $i
.mp3`.aac; done

The result is fine, but it seems we get aac files encoded with vbr

http://1clickcd.com/convert/aac/file-88815-1256688222.aac

Is there anything to do in the command or in the settings to get constant
bitratre instead of variable?

Thanks a lot
