When encoding to mp3 frequency is cut off at 16kHz

Asked by Michael

When encoding to mp3 320kbit the frequency spectrum always gets cut off at round about 16kHz. I guess it gets encoded with a --lowpass argument given to lame. I would like to change that to a higher frequency. Is that somehow possible?

At least a remark about whether it is intended that SoundConverter cuts off frequency at 16kHz for mp3s would be good.

No, this is not intended.
I've to check if the lowpass argument have a default value...

I've tested and confirmed the problem, and opened a new bug report.

Apparently this is a default setting for ffmpeg, reading here: http://ffmpeg.org/trac/ffmpeg/wiki/AACEncodingGuide. It can be changed by setting a different "-cutoff".

Can you help with this problem?
