With Annotone, you can add notes, flag takes, and save important ideas on any sound files (ie. WAV, MP3, FLAC) in seconds! Annotone is a powerful tool for audio professionals and teams to privately share feedback and edits with clients, editors, team members, producers, and co-workers.

Stop wasting time searching for files and timestamps: with Annotone, every note is just one click away, so you can quickly toggle between time-synced comments across several audio files.

Unlike other software solutions, you don't have to compromise on price or privacy to share notes with Annotone: your audio files are never uploaded to the cloud, and your license lasts for a lifetime (not a subscription with pesky storage limits).

How to share music production notes

For recording artists, mixing / mastering engineers, and sound designers alike, being able to quickly comment on specific timestamps and intervals while listening to a song is the key to efficient feedback. This makes working with clients or other creators to edit audio files much faster (minimizing the need for calls and emails).

Instead of having to cross-reference a Google Doc or email and search through files and timestamps manually, you can simply click to edit or play any time-synced note. This saves a ton of time, and more importantly eliminates tedious disruption to your creative flow.

Annotone is a powerful, local-first tool for sharing feedback on music. It allows you to comment directly on MP3, WAV, and FLAC files while you're listening, so you can easily share edits for mixing/mastering, vocals, and more in just a few clicks. You get the ease of adding comments in a SoundCloud-like interface, without having to upload your audio files to the cloud or pay a subscription. Collect feedback from your collaborators via a private review link that opens in the browser, or by simply sharing the plain-text notes file that anyone can open in Notepad.

How to find your best vocals

Searching through demo recordings to find the best vocals or melodies for a song you're working on can be extremely tedious and disrupt your creative flow. Annotone audio collaboration software makes this process painless and incredibly fast.

While Annotone's "Comment" mode allows you to add comments to an individual track and compare variations, the "Chooser" mode is designed specifically for isolating your best takes.

You can add notes across as many tracks as you want and mark your favorite parts with star ratings and 'keeper' or 'maybe' flag. Instead of manually toggling between files and searching for timestamps, you can simply click on any given take to play the audio at that part or edit your notes.

To get the most out of Annotone, use the keyboard shortcuts:

  • Press C to add a comment at the current timestamp, or press I and O to select a range.
  • Press Enter once to edit your comment and twice to save.
  • In "Chooser" mode, use the ↑ and ↓ arrow keys to switch between recordings.
  • In "Chooser" mode, press K for keeper, M for maybe, or N for no. Use 1–5 to add a rating and 0 to clear it.

Whether you're a producer, mixing / mastering engineer, or a singer, Annotone makes it easy for your collaborators to provide feedback on your music.

How to share feedback with clients as a freelance audio professional

Many music producers and songwriters work primarily on a contract basis (often remotely) with their clients. Sharing notes via email (or worse, Zoom calls) is tedious and reduces your hourly earnings.

Annotone's local-first audio annotation tool makes it easy to add notes and share feedback on audio files. You can share as many private review links as you'd like with your clients via Annotone, and they can easily add and reply to comments with the same SoundCloud-style interface.

Most importantly, you don't have to pay for another subscription just to share feedback. Annotone links to audio files via local directory paths (just like your DAW), so you can keep sharing your audio files however you already do.

Enjoy the convenience of a user-friendly, purpose-built collaboration tool for audio professionals, without the cloud storage limits or the risk of your stems leaking.

How to review podcast episode drafts

Annotone makes it super easy to take notes while listening to a podcast or an audiobook. Instead of manually jotting down timestamps and filenames or scheduling a meeting, you can simply let the audio play and click wherever you want to add a note (or hit the "C" button on your keyboard), type in your thoughts, and hit "Enter" to save.

If you want to select a range in your track (for example, if there's background noise in a certain section), you can either click and drag on the waveform, or use the "I" (in) and "O" (out) keys while the audio is playing to comment on an interval. Annotone was carefully designed to make it smooth and fast to add comments in real-time while listening to an audio clip. Skip the emails, documents, and meetings, and bring the joy back to collaborating on audio!

How to add transcription notes to Zoom meeting recordings

Many automated webinars, training courses, and marketing teams use meeting recordings from apps like Zoom and Skype. With Annotone's local-first audio software, you can add notes to your audio files directly on your own device (no Internet needed) and without the hassle of subscriptions with cloud storage limits that longer media files quickly exceed.

Whether you're manually transcribing audio or adding editing notes, simply drop your meeting recording into Annotone and click and drag to add comments.

How to share notes with a voiceover artist

If you're narrating an audiobook, promotional video, documentary, or creative project, the final audio is certain to go through rigorous review. Annotone makes it easy to share notes with your collaborators, without ever having to upload your audio anywhere.

It's a great way to quickly make note of anywhere where you might have stumbled over or mixed up words: you can easily add comments with you listen using keyboard shortcuts (like "C" to add a timestamped note, or "I" and "O" to select an interval), so you're not constantly pausing for every note. The "Chooser" mode is a great way to review different concepts and creative approaches, and narrow down to the best. Annotone's local-first application is a robust and practical tool for voice professionals, making quality assurance and creative collaboration a breeze.

Make the switch: bring the joy back to audio collaboration

Notes apps and Google Docs are simple but tedious to write, and incredibly tiresome to review. Searching for timestamps and files is a surefire way to kill the creative flow.

On the other hand, basically every popular audio annotation tool on the market requires you to upload your audio files to the cloud, and charges you a subscription with storage limits.

Annotone gives you the best of both worlds: Convenient, blazing-fast interface. Private sharable review links. No audio files uploaded. Notes stored as plain-text files. Runs offline.
