Generally, performing sampling-rate conversion from a higher sampling frequency fs1 to a lower sampling frequency fs2 results in aliasing. It is known to use a low-pass filter, known as anti-alias filter, for avoiding this alias distortion. Its effect is to remove spectral contents above fs2/2 from the...http://www.google.fr/patents/US6681209?utm_source=gb-gplus-shareBrevet US6681209 - Method and an apparatus for sampling-rate conversion of audio signals
