[QUOTE="Sarel.wagner, post: 1117348, member: 25509"] In doing some research on energy content, I managed to find a file with content clear to 38kHz. Do not know what mic was used, most likely a calibration mic or a recording mic like the Earthworks QTC40 - 40kHz Omni Recording mic. In the following enhanced Temporal Frequency Analysi,s FFT was used to plot frequency and energy content over time. The brighter the colours are, the more energy it contains. At 19kHz the volume is already 32dB down from the peak energy. [B]The .wav file also attached.[/B] [ATTACH type="full"]15829[/ATTACH] Closer view: [ATTACH type="full"]15830[/ATTACH] Groetnis [/QUOTE]
