Details
Initially recorded as MS-stereo with Rycote HC-22 and BD-10 at 96kHz, 32bit float in Mai 2024. In Audacity bat calls at 20 kHz (Nyctalus) were duplicated to new tracks and separated by using high and low pass filtering and noise reduction. At the Nyquist Prompt "(lowpass8 (mult *track* (hzosc 16500)) 12000)" was used for a heterodyn transformation of the bat calls to below 10 kHz. Bat calls were eliminated on the original track by low pass filtering and tracks were mixed.
