Frequency resolution fft sample rate

WebOct 22, 2012 · Frequency resolution of isolated spectral peaks well above the noise floor can be much finer than 1 DFT/FFT bin width by using a high-quality interpolation kernel. Resolution of separating of two individual peaks, with a minimum 3 dB separation gap, is roughly 2 to 3.5 DFT/FFT bin widths, depending on the windowing used. WebUltrasonic Analyzer can be used to analyze the calls of different animals (bats, dolphins), measure the frequency response of hi-end audio equipment or ultrasonic sensors. You can also analyze any imported audio file into a spectrogram context. Features. - Sampling rates: 44.1kHz, 48kHz, 96kHz, 192kHz, 200kHz, 250kHz, 384kHz.
