WebJun 30, 2024 · Nyquist’s Theorem. According to Nyquist’s Theorem, for an accurate digital representation of a sound wave, the sample rate must be, at least, two times bigger than the highest frequency going to be recorded.As the highest sound a human can hear has a frequency of 20 kHz, the minimum sample rate must be 40 kHz to be possible to digitalize … WebRead in an audio signal. Call pitch to estimate the fundamental frequency over time. [audioIn,fs] = audioread ( "Hey-16-mono-6secs.ogg" ); f0 = pitch (audioIn,fs); Listen to the audio signal and plot the signal and pitch. The pitch function estimates the fundamental frequency over time, but the estimate is only valid for regions that are harmonic.

WebWhen Raven opens a digital audio file, it sees a series of integer sample values that are proportional to the sound pressure (measured in pascals, Pa or µPa) received by the microphone or hydrophone when the recording was made. The sample values correspond to sound pressures at successive points in time as determined by the file’s sample rate.
