What Waveflow is not

Dropbox

Stores files.

Google Drive

Shares files.

Waveflow

Manages the review process — feedback, revisions, approvals, delivery.

The complete review workflow

From upload to signed-off delivery — without a single email thread.

1

Upload

WAV, MP3, AIFF, or M4A. Waveform generates automatically.

2

Share

One link. Client opens it in any browser — no account needed.

3

Comment

Client clicks the waveform. Comment is pinned to that exact second.

4

Revise

New version goes up. Previous comments stay on the old one.

5

Approve

Client clicks Approve. Decision logged with name, version, and timestamp.

6

Deliver

Final files bundled into one clean download link for the client.

The problem it replaces

Without Waveflow

  • —Clients describe timestamps in email — "around two minutes in, I think."
  • —You're not sure which version they're listening to.
  • —"Approved" in a WhatsApp message is not a record.
  • —Final files spread across email attachments and Drive links.
  • —Revisions made to the wrong version because notes weren't labelled.

With Waveflow

  • ✓Comments are pinned to the exact second on the waveform.
  • ✓Every version is numbered and labelled. Comments stay with their version.
  • ✓Approvals are logged with name, version, decision, and timestamp.
  • ✓Final delivery is one link. Everything in one place.
  • ✓Full revision history. You always know what changed and when.

What it includes

Every part of the review and approval workflow, in one product.

Timestamped comments

Every comment is anchored to the exact second it was left. No more "around the two-minute mark."

Full version history

Every upload is versioned. Comments stay attached to the version they were left on — nothing gets lost.

Formal approvals

Approved, Approved with Notes, or Revisions Requested. One click. Logged with name and timestamp.

Structured delivery

Bundle master WAV, stems, and MP3 into one download page. Clean handoff, every time.

Complete audit trail

Every comment, revision, and approval is logged in order. You always know exactly where a project stands.

Private by default

Files are stored on AWS S3 with org-scoped access. Review links use unique tokens. Nothing is public unless you share it.

Your clients need no account

You share a link. They open it in any browser, press play, click on the waveform to leave a comment at that exact moment, and submit their approval when done. Nothing to install. Nothing to sign up for.

From audio professionals

"Finally I can stop forwarding timestamped Google Doc notes. My clients leave comments directly on the waveform."

Alex R.
Freelance Mix Engineer

"The approval flow alone is worth it. I always know if a client has signed off and on exactly which version."

Maria S.
Mastering Engineer

"My podcast clients love the review link. They click, listen, and type — zero friction on their end."

James T.
Podcast Editor

Why we built this

Audio feedback has always lived in the wrong place — buried in email threads, scattered across voice notes, and described in vague terms that don't survive the next revision.

Waveflow is built specifically for the audio review process. Not adapted from a generic project tool — built from scratch for the way mix engineers, mastering engineers, and podcast editors actually work with clients.

The goal is simple: from the moment you upload a mix to the moment a client formally approves it, every step should be clear, logged, and professional.
