Audio Calc: Nyquist Frequency & Aliasing Calculator
x402
Audio Calc: Nyquist Frequency & Aliasing Calculator is a paid API for AI agents from audio-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).
Calculates the Nyquist frequency for a given sample rate, plus optional tone aliasing analysis (alias frequency, samples per cycle, below-Nyquist status) and the guard band above 20 kHz.

How this service works
Nyquist frequency for a sample rate, plus the alias frequency and samples per cycle of a tone, and the guard band above 20 kHz.
Output
Returns a JSON object with the Nyquist frequency (half the sample rate), the sample period in microseconds, the guard band above 20 kHz, a human-readable summary and common use description, and optionally (if a tone frequency is supplied) the tone's alias frequency, samples per cycle, cycles per sample, period in milliseconds, and a below-Nyquist verdict with explanatory reasons.
Example use cases
CD audio aliasing check
“I'm working with 44100 Hz sample rate audio — what's the Nyquist frequency and will a 21000 Hz tone alias?”
High-resolution audio guard band
“For a 96000 Hz sample rate, what's the Nyquist frequency and how large is the guard band above 20 kHz?”
Samples per cycle for mixing reference
“How many samples per cycle does a 1000 Hz sine wave have at a 48000 Hz sample rate, and is it safely below Nyquist?”
Technical details
Endpoint
GEThttps://audio-calc.x402tookit.com/sample-rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise Nyquist frequency calculations for a specific audio sample rate, want to verify whether a particular tone frequency will alias, or need to determine how many samples represent one cycle of a tone. It is specifically tailored for digital audio DSP contexts and returns audio-domain-native units and interpretations rather than generic math results.
Side effects
- Missing required sampleRate query parameter returns an error
- Non-numeric or zero/negative sampleRate values may return validation errors or unexpected results
- Very high or very low sample rates outside real-world audio ranges may produce degraded or flagged responses
- Payment failure (x402) returns 402 status before any computation is performed
