Looking for a Dropbox Replay alternative for audio? Try Notetracks.

Notetracks is a review tool built around the waveform: you upload WAV, MP3, MP4 or MOV files and reviewers leave comments pinned to the exact second, with stems and takes playing back in sync and notes that export as markers to Pro Tools, Audition, Audacity, Hindenburg, REAPER or Premiere. Dropbox Replay also reviews audio, but it is a general media review tool inside Dropbox, built around video, images and PDFs.

If you send mixes, episodes or chapters for feedback, Notetracks keeps every version, every note and every reviewer in one project, with one link.

Who each tool is for

Dropbox Replay

Dropbox Replay is a review and approval tool built into Dropbox. It handles video, images, PDFs and audio, with frame-accurate comments, markup on the picture and version comparison. It connects to Premiere Pro, After Effects, Final Cut Pro, DaVinci Resolve and Pro Tools. If your files already live in Dropbox and most of your reviews are video, it's a convenient choice.

Notetracks

Notetracks is built for teams whose work you have to hear: podcasts, music, audiobooks, voice-over and sound design. Every note sits on the waveform at the moment it's about, stems and takes play back together, and each new mix goes into the same project with its notes. When the review is done, the notes go back into your editor as markers. Video files go into the same projects, so a client can watch a cut and comment on the sound in one place.

Notetracks vs Dropbox Replay at a glance

Both tools let a reviewer open a link and leave timestamped notes. The difference is what the review is built around.

When Notetracks is the better choice

Notetracks is the better fit when the sound is the deliverable:

Notes that land back in your editor

Reviewers listen in the browser and leave notes like "the vocal gets buried here" or "re-read this line" at the exact second. You export the notes and import them into your editor, and each one becomes a marker or a label at its time, with who left it. Fix the pickups, upload the new version to the same project, and the reviewer hears what changed.

Frequently asked questions

Does Dropbox Replay support audio files?

Yes. Replay accepts WAV, MP3, AIFF, FLAC and other audio formats, and the Replay Add-On adds lossless playback up to 24-bit/96 kHz. The difference is the tools around the file: Notetracks shows the waveform, plays several tracks in sync and exports notes as markers to more audio editors.

Can I keep my files in Dropbox and use Notetracks?

Yes. You can import audio into a Notetracks project straight from Dropbox or Google Drive, so your masters stay where they are.

How do I compare versions of a mix?

Upload each new version into the same project. The notes for every version stay in one place, instead of a new link every round.

Do reviewers need an account?

Not in either tool. In Notetracks, reviewers open the share link and comment, and they never pay.

How much does Notetracks cost?

Every plan starts with a 7-day free trial, and plans start at $9 a month. See pricing for what each plan includes.
