towav

Documentation

Overview

Command towav converts mel spectrogram images (PNG) back to audio files (WAV).

This tool reconstructs audio waveforms from mel spectrogram PNG images using the Griffin-Lim algorithm. Since mel spectrograms don't preserve phase information, the reconstruction uses an iterative phase estimation process.

Usage:

towav <png_file> [sample_rate]

The output WAV file will be named <png_file>.wav Optional sample_rate parameter (default: 44100 Hz)
