# GPU FFT

This project demonstrates the use of the `gpu_fft` library in Rust to perform Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) on a generated sine wave signal. The application calculates the dominant frequencies in the signal and prints them along with their power.

## Features

- Generate a sine wave signal.
- Perform FFT to analyze the frequency components of the signal.
- Calculate the Power Spectral Density (PSD).
- Identify and print the dominant frequencies in the signal.
- Perform IFFT to reconstruct the original signal.

## Requirements

- Rust (1.84.1 or later)
- `gpu_fft` crate

## Installation

```base
cargo add gpu_fft -F wgpu
```

## Usage

To run the application, use the following command:

```bash
cargo run --example simple
```

The program will generate a sine wave with a specified frequency and sample rate, perform FFT, and print the dominant frequencies along with their power.
