Overview
Waveform_FFT is a Flutter package that enables real-time audio visualization by processing microphone input using Fast Fourier Transform (FFT). It captures audio data from the device's microphone and converts it into visual waveforms and frequency spectra, ideal for music apps, audio analyzers, or interactive sound projects. The package supports Android, iOS, and Linux platforms, making it suitable for cross-platform audio applications. With minimal setup via pub add, developers can integrate live audio analysis into their Flutter apps.
