Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of fft.js, so you can see the experience inside your AI.

It does not authenticate your account with fft.js. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions fft.js owners ask.

  • 01

    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.

  • 02

    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.

  • 03

    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.
