Bandmixr offers an AI-powered solution for music mixing and mastering, designed for producers, bands, and vocalists. It allows users to upload their raw track stems, including instruments and vocals, and receive a release-ready song in minutes. The platform supports up to 24 stems and analyzes each one for level, tone, dynamics, and timing before applying automated mixing and mastering processes. Users can fine-tune volumes, panning, and effects, or use the automated settings as is. The mastering engine provides loudness-matched output with controlled peaks, ready for streaming platforms like Spotify and Bandcamp. Bandmixr also features a Mix Analyzer for instant feedback on loudness, true peak, clipping, stereo issues, and tonal balance, offering a free 30-second preview of potential improvements. Additionally, the Rehearsal Cutter tool can automatically split long recordings into individual songs, supporting both multitrack stems and simple stereo recordings. The service is accessible entirely within the browser, requiring no installation or plugins. Bandmixr supports a wide range of genres, including Rock/Indie, Pop, Acoustic, Punk, Metal, Jazz, Blues, Funk/Soul, Reggae/Dub, Hip Hop, and Electronic. Users retain 100% ownership of their music, with no licensing or usage clauses imposed by Bandmixr. While basic usage and one song download are free, additional downloads are available through paid plans.
