Tips

44.1 kHz is sufficient for all audible frequencies (Nyquist: 22.05 kHz)
Use 48 kHz for video projects — it's the standard for film and broadcast
Record at higher rates (96/192 kHz) only if you plan heavy processing

Frequently Asked Questions

Is 192 kHz better than 44.1 kHz?

For listening, no — human hearing tops out at ~20 kHz. Higher rates help during production (processing headroom) but the final master at 44.1/48 kHz is transparent.

What is the Nyquist frequency?

Half the sample rate — the highest frequency that can be accurately captured. At 44.1 kHz, it's 22.05 kHz (above human hearing).
