Still confused. After a lossy encode forget the source resolution, if we can recover the source resolution (even if is poor) we have a lossless encoder.
For a lossy output the best procedure is, like madshi know, decode to high resolution (64 or 32 bit float) make functions (mix, speed, resample, ..) with max resolution and, at end, down to the max resolution supported by the encoder (24 bit int for Surcode DTS, 32 bit float for NeroAacEnc, ...).
In lossless formats the precision is know by the bitdepth, in lossy formats by the bitrate (forget the bitdepth).
