About:
ARSS (Analysis & Resynthesis) is a command-line tool that analyzes an audio file to generate a spectrogram image. It uses advanced signal processing algorithms to decompose sound into its frequency components over time. The tool's main value proposition is its ability to accurately resynthesize the original audio directly from the generated spectrogram, enabling unique audio restoration and creative sound design experiments.

Key Features:

High-fidelity audio analysis and spectrogram generation
Accurate sound resynthesis from spectrogram images
Command-line interface for batch processing and automation
Supports both analysis and synthesis phases of audio processing

Use Cases:

Visualizing the frequency content of audio recordings for analysis
Experimental sound design by modifying spectrograms and resynthesizing
Audio restoration and forensic analysis of sound files
Educational purposes for learning about signal processing and acoustics

Alternatives:

Sonic Visualiser – More focused on visualization and annotation, lacks ARSS's specialized resynthesis capabilities
Spear – Provides partial tracking and additive synthesis, but ARSS offers a more direct analysis-to-resynthesis workflow
