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.
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.
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.
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.
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.
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.
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 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.
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.
Afinar captures your instrument and the browser's audio as two separate, perfectly synced tracks. Nothing to route, nothing to set up.
Play both tracks together. Mute, solo, and compare. Keep the takes worth keeping, and actually hear yourself improve over time.
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.
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.
Playing both tracks in sync.
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.

Afinar adds a touch of reverb and delay while you play, so you enjoy the take and sit nicely in the track. But it records everything dry. Every take plays back both ways, and effects are never baked in. The polished version is there to enjoy. The raw version is there to tell you the truth.
Lush and forgiving. Lovely to play along to, and quietly smooths over loose timing and soft attacks.
Bone dry. Exactly what you played, with nowhere to hide. This is the take that tells you what to fix.
Your instrument and the backing, captured separately and locked in time, down to the sample.
Tabs, lessons, backing tracks. If it plays in your browser, you can play along to it and record.
No BlackHole, no audio routing, no DAW to configure. Open Afinar and press record.
Hear both tracks together, mute or solo either one, and zero in on exactly what to fix.
Export a take or send it on. Your recordings stay yours, on your Mac, never uploaded.
Tune up fast without ever leaving your practice space or breaking your flow.
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.
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.
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.
It's in early development for macOS. Leave your email and we'll send you the beta the moment it's ready.
