Every bounce. Every revision. Credited.
Lossless delivery, version history that survives the project, and credits attached at the source. The engineer workflow that actually respects your work.
Lossless, full stop
WAV, AIFF, FLAC delivered at original sample rate and bit depth. No transcoding, no surprise compression in the pipeline.
Every revision saved
V1, V2, master_v3_LUFS-corrected. Compare side-by-side, restore any version, attach engineer notes per bounce.
Credit at the source
Mix and mastering credits captured on the project, not chased after release. Surfaces on the release page automatically.
Timestamped notes
Artists pin feedback to the waveform. You see "snare 1:42" instead of "around the second chorus."
Sessions and stems welcome
Pro Tools, Logic, Ableton sessions. Stems folders. Reference tracks. All previewable in-app, organized in nested folders.
Links that don't die mid-project
No 7-day countdown. The link the artist got on day one still works on the day of release.
Stems arrive in one folder, not seventeen WeTransfers
The artist drops stems, references, and session notes into the project. You open one place and find everything at original quality. No expired links, no five-part archive, no chasing the missing vocal take.
- Lossless WAV, AIFF, and FLAC pass through untouched at original sample rate and bit depth.
- Up to 10GB per upload, so a full Pro Tools session fits in one drop.
- Stems sit in nested folders alongside the rough mix and reference tracks.
V1 to master, every revision keeps its place
Bounce mix v1. Upload it. The artist plays it in the browser and pins comments to the waveform. Bounce v2 with the changes, and v1 stays underneath, never overwritten. Six rounds in, the stack still reads cleanly.
- Every upload becomes a numbered version automatically — no FINAL_FINAL_v3 in the filename.
- Compare any two versions side-by-side and A/B without leaving the project.
- Engineer notes per revision so "EQ pass on lead vocal" is searchable months later.
Recall notes survive the year between sessions
Six months later the artist comes back for an alt mix. Open the project on your phone, read the notes you wrote on v7, restore the version the master was cut from. The chain stays intact. No DAW archaeology, no guessing which bounce went to mastering.
- Restore any prior version as the current one in a single tap, from desktop or mobile.
- Per-version notes capture the chain — bus settings, reference levels, what the client asked for.
- A permalink per version means you can send the mastering engineer one specific bounce.
Your credit travels with the release page
Add yourself as mix engineer on the project once. When the artist publishes the release page, your credit is on it. Same for the mastering engineer. No chasing PR teams, no spelling corrections in DSP backends, no missing line in the liner notes.
- Capture mix and mastering credits at the project level, not on the day of release.
- Credits surface on the public release page when the artist publishes.
- Metadata travels with the file — ISRC, contributors, and roles stay attached.
Sign the agreement once, export the paperwork when accounting asks
Engineering work earns a flat fee, points on the back end, or both. Capture the deal in the project, e-sign once, and you have the PDF when the label needs proof and the CSV when accounting wants a row. No DocuSign back and forth, no scanning a printed page on tour.
- Agreements e-sign in the project — flat fee, points, or hybrid.
- Export PDF for the label and CSV for accounting any time.
- Splits and contributor terms stay attached to the track they describe.
