Dear Ajith,


1.    If the original recording is CONVERTED at another frequency sample
rate then the original, the pitch and duration will be affected.

2.    If the original recording is RECORDED at another frequency sample
rate then the original, the pitch and duration will NOT be affected.
2.1   Nevetheless, recording at a frequency sample rate lower then the
original will impoverished the quality of the timbre.
