Best Free Audio Mastering Software of 2026

Euphona is an AI audio production platform that runs in the browser. Producers, engineers, musicians, podcasters and studios upload a mix, stems or a raw recording, and Euphona analyses it a single time: loudness and dynamics across the track, spectral balance, key and tempo, transients and any damage. Every tool then works from that shared analysis. AI mastering returns a measured loudness report and keeps a -1.0 dBTP true-peak ceiling by default. Stem separation splits a finished track into up to six stems. Restoration removes hum, clicks, noise, clipping and room sound. Vocal tuning, mixing from your own stems and binaural spatial audio for headphones complete the set. Each result plays back level-matched against the original, so you compare sound rather than volume. Developers can call the same engine through a REST API, with free test-mode keys. Free browser tools that need no account include a loudness checker, BPM and key finder, spectrum and stereo width analysers, a clipping detector and a vocal remover. Audio you upload is never used to train models. Plans start free with 10 minutes of processing; paid plans are $15, $29 and $79 per month.
