Audio sampling rate vs. microphone spec

Postby fengtso » Mon May 16, 2011 11:53 pm

Hi all,

I am trying to record a specific frequency of sound generated from android phone's speaker (e.g., 20kHz) and record with another phone's microphone. However, I am curious if the microphone on the android phone (i.e. Nexus One) will filter out that high frequency sound even the android SDK support that high sampling rate.

Thank you in advance.
