24kHz

24kHz is a digital audio sample rate. Sample rate refers to the number of times per second that an analog audio signal is measured and converted into a digital value. Higher sample rates generally allow for a more accurate representation of the original sound. For human hearing, the generally accepted upper limit of audibility is around 20kHz. The Nyquist-Shannon sampling theorem states that to accurately reconstruct a signal, the sample rate must be at least twice the highest frequency present in the signal. Therefore, a sample rate of 24kHz would theoretically be sufficient to capture frequencies up to 12kHz. This is below the upper limit of human hearing, meaning some ultrasonic frequencies and higher harmonics might not be perfectly reproduced. While 44.1kHz and 48kHz are more common sample rates for consumer audio and professional applications respectively, 24kHz can be used in certain scenarios where the full spectrum of human hearing is not a primary concern, or for applications with limited bandwidth or storage requirements. It is less common than other standard sample rates.
