The signal after the resampling is not the same than the original one,

With libsamplerate, I can state that the three
sinc based converters
have the following characteristics:
SNR Bandwidth
SRC_SINC_FASTEST 102.42 dB 80.23 %
SRC_SINC_MEDIUM_QUALITY 98.99 dB 90.68 %
SRC_SINC_BEST_QUALITY 97.43 dB 96.96%
where SNR is signal to noise ratio and Bandwidth its a percentage of
the theoretical best bandwidth (ie half of the minimum of the source
and desination sample rate).
What do you mean by 'signal to noise ratio' of a resample algo ?
I see no reason why it should produce noise,
