Mute a part. Make room for you.

  1. 01

    Play the song where you already listen.

    Open it in your music app or browser, and choose that app in Afinar.

  2. 02

    Take your part out, live.

    Choose Vocals, Drums, Bass, or Guitar & keys. Afinar separates the song as it plays, right on your computer, and never uploads it.

  3. 03

    Plug in and play along.

    Turn on Hear yourself to hear your instrument with the band, through the tone you chose.

How muting works

The easiest way to record yourself with music.

Afinar captures the song directly from its app alongside your voice or instrument.

No DAW.No routing apps.Just hit record.

  1. 01

    Choose what you’re playing with.

    Open a song, backing track, or lesson in your music app or browser. Select that app in Afinar.

  2. 02

    Bring yourself into the mix.

    Choose your microphone or instrument input. Turn on your camera if you want video.

  3. 03

    Hit record. Start the song.

    Press Record, then start the song. Afinar begins the take when the music starts.

Your first take, step by step

Ready for your feed. Or your teacher.

Record your take in portrait for TikTok, Instagram Reels, or YouTube Shorts, or in landscape for YouTube.

Rather not be on camera?Sometimes you want to share your playing, not your face. The Visualizer turns a take into a video of your sound, drawn as it plays. Add the song’s title and your name, pick portrait or landscape, and post it.

Trim. Balance. Share.Trim your take, balance your playing against the music, and share it as a video, a Visualizer, or just the sound. The sound can be your part alone.

Explore video recording

Find your tone. Bring it into every take.

Record. Listen. Improve.

Every take is a chance to hear more. Listen for the rushed chorus, the missed note, and the part you finally nailed. Keep your takes to hear your progress, or send one to your teacher for feedback.

Keep your tab or lesson open in your browser, and record yourself playing along.

A few things
before you start.

All the help you need
What do I need to get started?

A Mac with Apple silicon running macOS 26 or later, or a PC with Windows 11, plus wired headphones. Use a microphone for your voice or an acoustic instrument, or connect an audio interface for an electric instrument. Afinar guides you through the audio permissions the first time you open it.

Read the setup guide
Does Afinar use AI?

Not to make music. Afinar never writes, changes or fixes a note, so everything you hear is the original recording or you. Muting a part as the song plays and shaping your tone both happen on your computer. Afinar never uploads your songs, your playing or your takes, and nothing is trained on them.

How Afinar handles your data
Do I need to record video?

No. Record audio on its own, or switch on your camera for video. Choose portrait or landscape before the take. An iPhone used as your Mac’s camera or a 4K webcam gives a sharper portrait crop. With no camera, the Visualizer still gives you a video to post.

How do I share a recording?

Open your take, trim it if you like, and choose Share. Pick Video for a take you filmed, Visualizer for a video of your sound, or Audio for just the sound, with or without the song. Then upload the file to your social app or send it to your teacher. Include music only when you have permission to share it.

Is Afinar free?

Yes. Afinar is free for Mac and Windows.
