After upsampling the theoretical bandwith is indeed 48000Hz, but there
because the source signal had no frequency components above 24000, the
output signal should have no frequency components above 24000Hz. There
will however be resampling artifacts, but they will be below the noise
floor (ie 144dB for BEST converter).

Cheers,
