# Bandmixr > Bandmixr is an automatic online mixing and mastering platform for producers, vocalists and bands. Upload your raw stems (a beat and a vocal, a full multitrack session, or anything in between), pick a genre, and get a release-ready song back from your browser in minutes. Already have your own mix? Upload it directly for mastering only. No audio engineering knowledge required. Bandmixr also offers free browser-based musician tools: the Rehearsal Cutter (split long rehearsal, jam or live recordings into individual songs), the Mix Analyzer (check loudness, true peak, stereo image and tonal balance of a mix or master, with a free 30-second mastered preview) and the Stem Separator (split a finished song into vocals, drums, bass and the rest, or into an instrumental and an acapella). Bandmixr is built for producers and vocalists recording over a beat, bands recording in rehearsal rooms or home studios, and singer-songwriters tracking at home. The product runs entirely in the browser with no install and no plugins. Files are deleted on demand, are never used to train machine-learning models, and users retain 100% ownership of all music produced. Bandmixr claims zero rights. Bandmixr (bandmixr.com) is an independent mixing and mastering service and is not affiliated with BandMix (bandmix.com). ## Core pages - [Home](https://bandmixr.com/): Product overview, the three steps (upload stems, automatic mixing, master and export), and before/after demo songs in hip hop, acoustic and rock. - [Pricing](https://bandmixr.com/pricing): Free, Creator ($14/mo or $10/mo billed yearly), and Pro ($19/mo or $15/mo billed yearly) plans. - [About](https://bandmixr.com/about): Built by musicians, for musicians.

No signup, no upload, runs locally in the browser. - [Stem Separator](https://bandmixr.com/tools/stem-separator): Free stem splitter and vocal remover. Splits a finished song into vocals, drums, bass and other (guitars, keys, synths), plus the instrumental (everything but the vocals), with mute, solo and a waveform per stem. Runs locally in the browser; the song is never uploaded. Without an account it plays a 30-second preview; a free account splits whole songs and downloads every stem as a WAV file or all of them in one ZIP. - [Mix Analyzer](https://bandmixr.com/tools/mix-analyzer): Free check for loudness (LUFS), true peak, clipping, stereo image, and tonal balance with actionable feedback. Analysis runs locally in the browser with no signup. Where mastering would help, a free 30-second mastered preview plays, and one click masters the full track (first song free). ## Plans and pricing | Plan | Price (monthly) | Price (yearly, per month) | Storage | Stems per project | Stem duration | Downloads | |---|---|---|---|---|---|---| | Free | $0 | $0 | 1 GB | 16 | up to 8 min | 1 free, then pay-per-download | | Creator | $14 | $10 | 5 GB | 24 | up to 13 min | unlimited | | Pro | $19 | $15 | 10 GB | 24 | up to 13 min | unlimited | - Pay-as-you-go: no subscription needed. The first song download is free; after that an extra download costs $5 (1 credit; bundles: 5 for $20, 10 for $35). Credits never expire, and re-downloading the same result in another format is free. - Mastering reference matching: included on Creator and Pro. - Processed stem exports and priority mix processing: Pro only. - Rehearsal Cutter and Mix Analyzer: free for everyone, no account required. - Stem Separator: free. A 30-second preview without an account; whole songs and WAV downloads with a free account. ## Mixing and mastering capabilities - **Analysis**: every stem is read for level, tone, dynamics and timing before any processing starts. Unlabeled stems are placed by what the analysis hears. - **Auto Mixing**: a custom mix plan is built per song: balance, panning and depth per instrument, with EQ, compression, reverb, saturation and more; frequency clashes between instruments are resolved automatically; the result follows the conventions of the chosen genre, from hip hop and pop to rock, metal and electronic. - **Auto Mastering**: three presets: Streaming (optimized for Spotify/Apple Music), Standard (balanced), Loud (maximum punch and density). A reference track can be uploaded to guide tonal balance (Creator and Pro). Output is loudness-matched with controlled peaks, ready for streaming. - **Mastering-only flow**: skip mixing entirely: upload your own stereo mix and apply mastering directly. - **Post-mix tweaks**: after the initial draft, individual stem levels, reverb, and panning preferences can be adjusted before the final export. ## Supported audio formats - Mixing & mastering input: WAV, FLAC, MP3, AIFF (lossless recommended). - Mastering input limit: 180 MB per mix. - Stem upload limit: 150 MB per stem. - Output: 44.1 kHz / 24-bit WAV (also exportable as FLAC or MP3). - Rehearsal Cutter input: WAV, FLAC, MP3, MP4, M4A.

No licensing, no usage clauses, no transfer of ownership. - Bandmixr does not share, sell, or access uploaded files for any purpose other than processing the requested mix. - Files are permanently removed when deleted by the user. - The Rehearsal Cutter processes everything locally in the browser. Files never leave the user's device. - The Stem Separator splits songs locally in the browser. The song is never uploaded; the separation models download once and are cached by the browser. - The Mix Analyzer analyzes locally in the browser; the full file is never uploaded. Its optional 30-second mastered preview uploads only that snippet, which is deleted within an hour. ## Comparison context Bandmixr is most directly comparable to LANDR, eMastered, CloudBounce, BandLab, RoEx Audio, and MajorDecibel in the AI mastering category, and is in the same broader category as Cryo Mix, Output Studio, and similar AI mixing services. Bandmixr's positioning emphasizes (1) full-stem auto-mixing (not just mastering), (2) browser-based with no install, (3) user-controlled post-mix adjustments, (4) explicit zero-rights ownership terms. ## Contact - Email: hello@bandmixr.com - Twitter / X: [@Bandmixr](https://twitter.com/Bandmixr)
