🦋 n-point iDFT calculator app (DFT, IDFT, FFT)

DFT Calculator and Visualizer

DFT Calculator and Visualizer is an assist tool for college level students enrolled in digital signal subjects. The aim of this calculator is to help students cross-verify their DFT, IDFT, and Rx2FFT problems.

Features

• Dynamic list of n-points: add or remove points in an intuitive way.
• Supported operations: DFT, IDFT, and Rx2 FFT.
• Padding safety: automatically pad the input signal to 2^n when calculating FFT using Rx2 algorithm.
• Interactive output signal visualization on a stem-graph.

Contribution

Contributions are welcomed, but please know this project is built using Vibes ™ architecture. I made it when I was still learning Flutter, so it its pretty hard to refactor stuff without breaking something. I did a lot of cleanup when I resumed working on this app to support Material You, but overall the codebase is still a mess.
