Is is possible to do automatic upsampling of MP3's? I mean, if for instance a MPEG file is 32kHz, the output can be 44,1kHz anyway.
There's been some interest in whether something like this can be done as part of the decoding process,
There are several Linux audio drivers that do this when faced with hardware that will only operate at one (or a few) sampling frequencies. They simply replicate (or mabye try to linear interpolate) samples such that over a small time window the start and end samples are properly timed. Since it's the final output stage, it seems to be a sufficient solution.
