The old way

  • ✕Clients send feedback by email, WhatsApp, and voice notes.
  • ✕You're not sure which version they're listening to.
  • ✕Nobody knows if the client has actually approved.
  • ✕Final files buried in a Drive folder with no context.
  • ✕You lose track of what was changed and why.

With Waveflow

  • ✓All feedback lives on the waveform, at exact timestamps.
  • ✓Every version is labelled and versioned.
  • ✓Clients formally approve with one click.
  • ✓Final delivery is a clean, downloadable package.
  • ✓Full activity log so nothing gets lost.

How it works

Six steps from project to delivery.

01

Create a project

Add title, client name, type, and due date.

02

Upload your mix

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

03

Invite your client

Share a link or send an email invite. No signup required for them.

04

Receive feedback

Timestamped comments appear in real time. Reply and resolve.

05

Revise and upload

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

06

Get approval

Client clicks Approve. You deliver the final files. Project archived.

Everything you need

Built specifically for audio review workflows.

Timestamped Feedback

Clients leave comments pinned to exact moments in the audio. No more "around 2 minutes in."

Version History

Every upload is tracked. See which comments belong to which version. Never lose a note.

Formal Approvals

Clients approve, request changes, or approve with notes. One click. Clear record.

Clean Delivery

Bundle final assets into a structured delivery. Master WAV, stems, MP3 — all in one handoff.

Any Audio Format

Upload WAV, MP3, AIFF, and M4A. Browser-based playback with waveform scrub.

Full Project History

Every revision, comment, and approval is logged. Your projects have a complete paper trail.

What audio professionals say

"Finally I can stop forwarding timestamped Google Doc notes. My clients now 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 just click, listen, and type. Zero friction."

James T.
Podcast Editor
