SessionStem for mixing engineers
Revision rounds without the email archaeology
One link per song. Your client hears the mix losslessly, drops notes on the exact second, approves a specific version, pays, and downloads — while you stay in the DAW.
The revision problem every mixing engineer knows
Notes arrive as a voice memo, two emails, and a text that says "make the chorus hit harder." Nobody agrees which bounce is current. The client references "the version from Tuesday," and you dig through Mix_v7_FINAL_final2.wav trying to reconstruct what they heard.
None of that is a mixing problem — it is a delivery problem. Generic file links were never built for the loop of bounce, feedback, revise, approve that mixing actually runs on.
What a mix-first workspace changes
Timestamped comments on the waveform
A client note drops a marker at 1:47, on the file they were hearing. "Vocal is buried after the second chorus" stops being a scavenger hunt.
Immutable versions with held-playhead A/B
Every bounce you upload becomes a permanent version. Flip between v6 and v7 at the same spot with the playhead held in place — the fastest way to settle "did that fix it?"
Approvals that point at a file
The client approves a specific version, not a vibe. When the mix is signed off, there is a record of exactly which file that was.
Lossless review, originals intact
Clients stream a lossless preview in the browser and you deliver the true original — WAV, AIFF, FLAC, BWF. No silent transcode deciding your mix sounds different on their laptop.
Get paid before the mix leaves
Attach a balance to the project and final downloads stay locked until payment clears. Your client can hear everything — that is the point — but the files only leave once you are paid. No invoice chasing, no awkward "just checking in" email three weeks later.
Gating is per folder, so you can leave rough bounces open while masters and stems sit behind the balance.
Built around how a mix project actually flows
Each song gets one workspace with labeled folders — Uploads, Mixes, Masters, Stems, References. Clients upload session files and references through the same link they review from, so nothing arrives over six services. A live status bar shows where the song sits (editing, mixing, mastering), which quietly ends the "any update?" messages.
Clients never create an account or install anything. The link is the portal.
Common questions
Do my clients need an account?
No. Clients open a dedicated link in any browser — desktop or phone — and can listen, comment, approve, upload, and pay from there.
Which formats can I deliver?
Lossless formats including WAV, AIFF, FLAC, and BWF. Clients stream a lossless preview and download the untouched original file you uploaded.
Can I gate only the final files behind payment?
Yes. Payment gating is set per folder, so review bounces can stay open while masters and stems unlock on payment.
