Today i rendered a new track i was making from my daw (ableton) and when i converted the audio to mp3 in soundforge in order to send it to a friend in soundforge i experienced some trouble.
I rendered the audio from ableton as a 16 bit file with dither (i used the dithering fuction from my limiter used in the Master Channel, Voxengo Elephant, instead of Ableton's dither, as i've read somewhere it's not soo good), and the audio track with sounded good with no imperfections, when converted to mp3 had some little spikes which according to soundforge level meter made it clip.
What may be causing this?
Here is an image comparision of the 2 files, to make myself clear, because my english is not very good.
Thank you!
