Why people use fft.js
Fourier Transform Engine for Signal Processing Accuracy
This Connector lets your agent do that work directly. You just point the agent at the data, and it handles the transform and extracts the top frequencies for you. You get a clean summary of the signal's behavior without leaving your chat window.
What Vinkius changes
You get mathematically perfect frequency analysis without any AI hallucination.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about fft.js.
The practical details behind the request, access and result.
Can the Fourier Transform Engine find cycles in my financial data?
Yes, it can identify recurring patterns in stock prices or other time-series data. It converts the prices into frequency components to show you exactly how often cycles repeat.
Does this Connector work for audio files?
It processes the numeric arrays of audio data. You can use it to find the most prominent pitches or frequencies in a recording.
Is the math accurate for signal processing?
Yes, it runs on your local CPU using a dedicated engine. This means you get mathematically perfect results instead of an AI guess.
How does it handle different data lengths?
The Connector automatically pads your data to the nearest power of 2. This ensures the math runs efficiently without you having to manually adjust your input.
Can I use it for vibration analysis?
It's perfect for that. It can take raw sensor data and tell you which frequencies are the strongest, helping you find mechanical issues.
Do I need to know math to use it?
No, you just need to provide the data array. The Connector handles the complex multiplications and gives you a simple list of the top frequencies.
Does my array length need to be a power of 2?
No. The engine automatically zero-pads your signal to the nearest power of 2 before transforming. You can send any array length.
What format is the output?
The engine returns a JSON containing the top 3 dominant frequency bin indices with their magnitudes, plus a preview array of the first 10 absolute magnitudes for quick analysis.
Can it perform inverse FFT (IFFT)?
Currently, this capability is optimized for forward FFT frequency extraction. A dedicated IFFT capability for signal reconstruction could be added in future updates.
