Feedback you can act on, right on the sound

Your client listens and comments at the right moment, with no account and nothing to install. Here is what they see:

The waf.fm listening player: waveform and comments at the right moment.

This player is real: open the listening page and leave feedback at the right moment.

Simple for your client, phone included

They listen and leave their notes from their phone, with no manual.

Portrait or landscape — nothing to install, no account to create.

04

Spoken feedback, at the right timecode

Your client records a voice note, pinned to the exact timecode. No account, nothing to install: the browser is all it takes.

Hum an idea, tap out a rhythm, set the tone: what is hard to write takes seconds to say.

05

The desktop app

Right-click a mix in the Finder, or drop it on the menu bar: the approval link is copied right away and the upload carries on in the background.

Your data

Your files are protected

You send a mix to a client: you decide who opens it, until when, and what they can do with it. Your files stay yours.

  • Unguessable links

    Every link carries a random 128-bit token: only someone who was sent it can open it.

  • Password

    Protect a link with a password. It is hashed on the server (scrypt), never stored in clear.

  • Expiry

    Set a closing date: past that day, the link no longer opens.

  • Close it now

    Close a link at any moment, in one move, without waiting for its expiry.

  • Downloads your way

    Allow everything, the MP3 only, or no download at all: the server refuses any download you haven't allowed.

  • Two-factor authentication

    A second check when you sign in, on top of your password or the link we email you.

  • Nothing resold

    No data sold, no advertising, no third-party analytics.

  • Real deletion

    A deleted file is destroyed, storage included, after 30 days in the bin, or as soon as you empty it. Accounts are deleted from the settings.

  • Data export

    A JSON export from the settings: profile, preferences, comments and your files' metadata.

  • Server and database in Paris

    The application and its database (accounts, written comments, link settings) run in Paris. Audio and video files, like the database backup, are stored separately, with Cloudflare.

The detail — data processed, retention periods, providers — is in our privacy policy.
