GoHz is a fast, trash-polished toolkit for audio analysis and manipulation, written in Go.

• split – splits an audio file into basic stems (bass, drums, music, vocal) using ffmpeg filters or the demucs command.
• analize – command line audio analyzer that reports loudness, spectral stats and more. Requires ffmpeg and ffprobe, optional aubio for tempo/pitch/key.

Build everything from the project root:

./build.sh

Or build components individually:

go build ./split

go build ./analize

The audio/ directory contains test MP3 files for future benchmarking and calibration.
