you were clear except for the one detail. A number of programs can
open edit and resave as MP3 but none can restore full fidelity.
i believe none edit native mp3 format. it has to go back to linear PCM
(be de-coded), edited, then *re-encoded*.
you'd be better to work at 16/44 linear PCM at all times...
I'm not sure what Lou Judson was planning to write about the Fraunhofer
codec, but let me note my experience. It is the most conservative of
those I know, rolling off high frequencies explicitly so that the
inaccuracies and artifacts are not reproduced and exacerbated. As a
result, it is the least harmful on recoding.
Other compressors I have tested appear to have better high-end response
but at the cost of artifacts and inaccurate reproduction after the
There is no free lunch.
