A focused practice studio for macOS

Play along in your browser. Hear how you really sound.

A practice space in the shape of a browser: play along to any lesson or track, record it, and hear exactly where you stand. The feedback loop, minus the setup.

macOS · works with any USB audio interface
The oldest advice in music

Every teacher tells you to record yourself. Almost nobody does.

Because doing it for real has always meant wrestling virtual audio drivers, a DAW, and your system sound settings just to capture your playing next to the track. So students reach for a phone propped on a music stand, hear mush, and give up. Afinar removes every step between you and an honest recording.

Why it works

Recording yourself isn't a nice-to-have. It's the feedback loop.

Research on building any skill keeps landing on the same place: progress comes from a feedback loop, not from repetition alone. Recording is how you get that feedback when there's no teacher in the room.

Deliberate practice
Feedback turns repetition into progress.

Decades of research on skill-building find that practice improves you only when each attempt is followed by noticing the gap and adjusting. Without that loop, repetition mostly cements what you already do.

Self-assessment
Hearing yourself back sharpens your ear.

In a 2025 study, music students who recorded and listened back assessed their own playing more accurately, closer to how an expert judged it. And for hearing what's actually in the sound, audio came out ahead of video.

The catch
It works best against a reference.

Recording in a vacuum does little on its own. The gains show up when you compare your take to the music you're aiming for, which is exactly what Afinar captures right alongside your playing.

The honest version: recording is a tool inside good practice, not a substitute for it. Afinar's whole job is to make the recording part effortless, so the feedback loop actually happens instead of staying advice you never follow.

A fair question

Can't I just use GarageBand?

GarageBand is free, it's already on your Mac, and it's the obvious place to start. But even the friendliest DAW asks a lot of someone who just wants to hear themselves play, and every other DAW asks more. The hard part was never recording your instrument. It's capturing the track you're playing along to, in sync, without losing an afternoon to setup.

GarageBand, or any DAW
A studio you have to drive
  • Install a virtual audio driver like BlackHole
  • Build an aggregate device and route your system sound
  • Set up tracks, inputs, and a mixer before you play a note
  • Hope your instrument and the track stay in sync
  • Dig each take out of a folder full of project files
Afinar
One window, built for practice
  • Open your material in the built-in browser
  • Press record, and get two perfectly synced tracks
  • Listen back, mute, solo, and compare
  • Every take filed under its piece, automatically

GarageBand is a great studio, and free is hard to beat. Afinar isn't trying to be a studio. It does the one thing a studio makes hard, simply enough that you'll actually do it.

How it works

From browser tab to honest playback, in three moves.

01

Open your material

Pull up a tab, a lesson, or a backing track in the built-in browser, whatever you already practice with. It lives right inside Afinar.

02

Press record

Afinar captures your instrument and the browser's audio as two separate, perfectly synced tracks. Nothing to route, nothing to set up.

03

Listen back

Play both tracks together. Mute, solo, and compare. Keep the takes worth keeping, and actually hear yourself improve over time.

One window, two tracks

Your material and your recorder, side by side.

Your material is whatever you already practice with in a browser: a video lesson, a tab or chord sheet, a backing track, a page of sheet music. It sits on the left. Your recorder sits on the right, capturing your instrument and that material as two clean, perfectly synced tracks. No tab-switching, no second app, no setup ritual before a take.

Video lessonsTabs & chordsBacking tracksSheet music
Listen back

Then hear both tracks together, honestly.

Play your take against the material you recorded to, locked in sync. Ride the mix, mute or solo either track, and hear exactly where you're in the pocket and where you're not.

Your library

Every take, kept and sorted by the piece you're working on.

Afinar files each recording under the piece it belongs to, so your practice builds into a record instead of a pile of nameless files. Rate the takes worth keeping, and listen back across weeks to hear, not just hope, that you're getting better.

Works with

Sound your best, through your dream rig.

Link your Tone3000 account and its whole library lands inside Afinar. Search thousands of real amp and cab captures — a glassy clean, a cranked vintage tube, a modern high-gain wall, whatever tone you’re chasing — and load any of them instantly. No downloads, no plugins, no wrangling files. Pick your rig and play. And because Afinar records your dry signal, the rig stays live even on playback: swap captures mid-take and hear yourself through a completely different amp, without re-recording a note.

Search the full library

Thousands of community captures of real amps and cabs, right in the app.

Load instantly

No downloads, no plugins — straight into your signal.

Reshape any take

Swap rigs live, even on playback, because your recording stays dry.

Amp and effects, or dry

Play through your rig. Hear yourself without it.

Afinar records only your dry signal. Your amp and effects stay live, never printed into the take, on playback too. So any recording is yours to reshape after the fact: load a different Tone3000 capture, change the reverb and delay, or strip it all back to the bare DI to hear exactly what you played. All while it plays back, without re-recording a note.

Lush, forgiving, a little flattering. Your amp tone plus a touch of reverb and delay, it quietly smooths over loose timing and soft attacks.

One take gives you both: the version you enjoy, and the version that tells you what to work on.

Features

Everything you need to capture a take. Nothing you don't.

Two synced tracks

Your instrument and the backing, captured separately and locked in time, down to the sample.

Works with anything

Tabs, lessons, backing tracks. If it plays in your browser, you can play along to it and record.

Zero setup

No BlackHole, no audio routing, no DAW to configure. Open Afinar and press record.

Listen back in sync

Hear both tracks together, mute or solo either one, and zero in on exactly what to fix.

Save and share

Export a take or send it on. Your recordings stay yours, on your Mac, never uploaded.

A built-in tuner

Tune up fast without leaving your practice space or breaking your flow.

Built-in metronome

Keep time while you practice, without reaching for another app.

Who it's for

For players serious about getting better, and the teachers helping them get there.

For players

Stop guessing how you sound.

The recording always tells the truth. Capture a take, listen back, and let your own ears do the work that mirrors and metronomes can't. Then watch the takes get better, week over week.

For teachers

The habit you've always recommended.

Recording yourself is the advice every teacher gives and few students follow, because the tools were a nightmare. Afinar makes it effortless enough that they'll actually do it. Recommend it once.

What you'll need

Afinar records your real instrument, so you'll need one simple thing.

Your playing has to reach your Mac through an audio interface: a small box that turns your guitar or bass into a clean signal your computer can record. Any class-compliant USB interface works. If you're starting from scratch, something like IK Multimedia's iRig line is an affordable, plug-and-play way in.

You don't need effects or a fancy rig to benefit. A clean signal is the best way to hear your real playing: the good, the rough, and the parts worth fixing.

Common questions

Common questions about recording yourself.

What’s the easiest way to record myself playing along to a YouTube backing track on a Mac?

The hard part isn’t recording your instrument, it’s capturing the YouTube audio at the same time, in sync, without extra software. Most guides send you to install a virtual audio driver like BlackHole, build an aggregate device in Audio MIDI Setup, and route everything through OBS or a DAW before you can play a note. It works, but it’s a lot of setup for something you just wanted to practice to. Afinar is built for exactly this. You open the YouTube video in its built-in browser and hit record. It captures your instrument and the video’s audio as two separate, perfectly synced tracks, with no drivers to install and nothing to route. When you’re done, you play both back together and hear how you actually sound against the track. It’s macOS only, and you’ll need any USB audio interface to plug your instrument in.

How do I record my instrument and a backing track separately at the same time?

Recording your instrument alone is easy; any recording app does it. The hard part is capturing the backing track playing on your computer at the same time, in sync, and keeping the two on separate tracks so you can balance or mute them later. The usual route is installing a virtual audio driver like BlackHole and building an aggregate device to route your system audio into a DAW. Afinar does it with no setup: open the backing track in its built-in browser, hit record, and you get your instrument and the track as two separate, perfectly synced recordings. macOS only, and you’ll need a USB audio interface.

Is there a simpler alternative to OBS and BlackHole for recording yourself playing?

Yes. OBS plus BlackHole plus an aggregate device is the standard answer, and it works, but it’s a lot of moving parts for something you just want to practice to, and easy to get the routing wrong. Afinar was built to replace that whole chain. You open your backing track or lesson in its built-in browser and press record. It captures your instrument and the computer’s audio as two separate, perfectly synced tracks, with no virtual drivers, no aggregate devices, and nothing to route. You play both back together to hear how you sound. macOS only, and you’ll need a USB audio interface for your instrument.

How can I hear how I actually sound when I practice?

Record yourself and listen back. It’s the fastest way to hear what you can’t catch while you’re playing: rushing, loose timing, notes ringing into each other. Most players never do it because the setup is a pain. Afinar makes it the default: open a song or lesson in its built-in browser, hit record, and it captures your playing and the backing track as two separate, synced tracks. You play them back together and hear yourself honestly, against the music you were aiming for. It records a clean signal, so what you hear is what you actually played. macOS, with any USB audio interface.

Do I need an audio interface or a DAW to record myself playing at home?

You need a way to get your instrument into the computer, but you don’t need a DAW. A DAW like Logic or Reaper can record you, but it’s built for producing music and adds a lot of steps before you can play a note, especially if you also want to capture a backing track. What you do need is a USB audio interface, a small box your guitar or bass plugs into. With Afinar, that’s the whole kit: plug in through the interface, open your track in the built-in browser, and record. No DAW required. macOS only.

What’s the easiest way to practice songs on my computer and record myself?

Open the song, play along, and record both at once so you can hear how you did. The friction is usually the recording part: capturing the song playing on your computer together with your instrument normally means extra software and audio routing. Afinar removes that. You pull up the song, tab, or lesson in its built-in browser, press record, and it captures your instrument and the track as two separate, perfectly synced tracks. Listen back to hear where you’re locked in and where you’re not, and keep the takes worth keeping. macOS, with any USB audio interface.

How do I play along to a YouTube lesson and record myself at the same time?

Open the lesson in Afinar’s built-in browser and press record. It captures the lesson’s audio and your instrument as two separate, perfectly synced tracks, so you can listen back to the lesson and your playing together and hear exactly how you did. No screen recorder, no virtual audio driver, no routing, which is the setup playing along to a YouTube lesson normally requires. When you’re done, mute either track, compare, and try again. macOS only, and you’ll need a USB audio interface to plug your instrument in.
