Node-based Audio Router
"Splitwave is a free node-based audio router for macOS. Wire microphones, system audio, per-app capture, and WAV files into a visual graph, run them through a chain of effects - EQ, compression, reverb, limiting, and more - then send the result to speakers or record it in WAV, FLAC, AIFF, MP3, Opus, or AAC.
Splitwave is open-source and built with Tauri + Svelte."
