All,
Is there any point in using a higher sample rate if the mics we use
only go up to 20 kHz? We would not be able to capture animal sounds
above 20 kHz no matter what the settings on the recorder.
I note that the Sennheiser MKH 800 goes up to 50 kHz but is very
expensive. Most other Sennheiser mics only go up to 20 kHz.
When Raimund recorded Noctule bats (20-45 kHz) with inbuilt mics on a
Sony PCM D50 recorder, he noted that the mic sensitivity went up to
30 kHz. Does anyone know what the inbuilt mic sensitivity is for the
Olympus LS-10? I cannot find that in the specifications.
