Your client texts “something feels off around the middle” with no timestamp. You spend two hours decoding notes across WhatsApp, email, and a voice memo — then do another round you're not billing for. MixNotes gives clients one link to pin notes directly on the waveform, so every revision round is the last one.

The real cost
Your client sends a voice memo at 11pm describing the issue in three sentences — no timestamp, no context. The band follows up on WhatsApp about a different version. The A&R replies to an old email thread about a mix you already revised.
You spend two hours consolidating notes you still can't fully act on, then do another revision round. At $100/hour, that's $200 per project walking out the door. Multiply that across 10 projects a month, and scope creep is costing you $8,000–$10,000 a year in unbilled time.
The problem isn't your clients — it's the tools. No timestamps. No version control. No way to close the loop.
How it works
Upload any audio file — MP3, WAV, FLAC. MixNotes builds the waveform instantly, so your client can see and hear exactly where to pin their note.
Your client clicks, listens, and drops a note right on the waveform at the exact second they hear the issue. No signup required. No account wall. No excuse not to give feedback.
Work through each note, tick it off, upload your next version. When every note is resolved, the project is done — and your revision limit means something.

Why mix engineers switch to MixNotes
When every note has a timestamp, you fix it once and close it. No more revisiting a chorus you already addressed in v2. Closed notes stay closed — your revision policy finally has teeth.
"At 0:47 — the snare is poking through the vocals" is actionable. "Something feels off" isn't. Clients click exactly where they hear the issue. Precise notes mean one revision round, not three.
A clean review link signals a professional operation — not a cobbled-together tool stack. Clients who feel like they're working with a pro book you again, and send their contacts your way.
Upload R1, R2, R3 into the same timeline. See exactly how the mix evolved from rough to final. No more digging through folders for the FINAL_FINAL.wav that had the snare fix.
Drop a link in WhatsApp, email, or Discord. They open it, hit play, and start reviewing. No downloads. No account registration. No "how do I log in?" texts at midnight before a deadline.
Resolve notes one by one. When every comment is green, print the final. No more wondering if you missed something — or getting "one more thing" after you already sent the WAV.
How it stacks up
Whether you're using email threads, Dropbox folders, or a dedicated tool like Filepass — every option either misses timestamps, locks clients behind a signup wall, or both.

What engineers say
"I was drowning in WhatsApp voice memos, email threads, and "can you quickly..." requests. Now my clients pin notes right on the waveform. My average dropped from 4 revision rounds to 1. I'm closing twice as many projects per month without working more hours."

"I used to get notes like "the low end feels muddy somewhere in the second half" — no timestamp, no context. Now every note has a pin on the waveform. My mastering sessions went from 3 rounds to 1. My clients think I'm a wizard. I just have better tools."
Sarah Kim
Mastering Engineer — 500+ release credits
"I sent a review link at midnight. By morning my client had 8 notes — all pinned, all timestamped. I fixed everything in one session, uploaded the final, and the project was closed. No back-and-forth. No "one more thing." That's how every mix should end."
