Audio Sample Rate Calculator
Calculate minimum sample rate from Nyquist theorem and find the nearest standard audio sample rate. Essential for audio recording and digital signal processing.
How to Use the Audio Sample Rate Calculator
- Enter the maximum frequency in your audio signal (Hz).
- Click Calculate to get minimum sample rate and the recommended standard.
- Choose an appropriate bit depth from the suggestions.
Anwendungsfälle
- •Configuring audio interfaces for recording sessions.
- •Understanding DSP requirements for signal processing.
- •Selecting sample rates for game audio engines.
- •Teaching digital audio fundamentals.
Formel
Minimum sample rate = 2 × max frequency (Nyquist theorem). Recommended = nearest standard rate above minimum.
Häufig gestellte Fragen
What is the Nyquist theorem?
The Nyquist theorem states that a signal must be sampled at least twice its highest frequency to be accurately reconstructed.
Why is 44,100 Hz the CD standard?
Human hearing tops at ~20 kHz. 44,100 Hz (> 2×20,000) was chosen to exceed Nyquist with a filter margin.
When should I use 96 kHz?
Use 96 kHz for professional audio production or when downsampling will be applied, to preserve quality through processing.
