← Back to Yalaloop

I started building Yalaloop because Audacity wasn’t built for practice. I was working through the fingerpicking pattern in “Love You More” by Racoon — fast 16th notes with a shuffle feel — and to really nail the timing I needed to slow it down and loop a single bar perfectly, over and over. Audacity could do the slow-down and the loop, but it couldn’t keep multiple practice sections per track, and switching to a different song meant rebuilding everything from scratch.

Yalaloop is the tool I wished I’d had.

Audio you can actually load

Yalaloop opens audio files on your device. Streaming services (Spotify, Apple Music’s own subscription) are DRM-locked and won’t load into a practice app — you need files you’ve actually purchased and downloaded.

Practical sources:

When you want only the guitar

Some songs are easier to learn when the rhythm section is muted. LALAL.AI is the cleanest stem-splitting service today — upload the track, get back separated vocal / drums / bass / guitar / other stems, then load the stem you want into Yalaloop. It’s a paid online tool with a free trial.

Yalaloop will integrate stem splitting directly in a future release; until then, the upload-and-import flow works.

How I actually use it

Three workflows that come up most often in my own practice:

Setup happens on my laptop, where the bigger screen makes loop-boundary drag-select easier. The actual practice happens on my phone with the guitar in my hands — same loops, same settings, ready to go.

Common questions

Can I loop just one bar to master a tricky lick?

Yes. Drag-select any section of the track to set a loop, or tap the loop button at the start and end to mark boundaries while audio is playing. Yalaloop holds the loop sample-accurately with a short crossfade so the seam doesn’t click. I use this constantly — for a 16th-note hammer-on/pull-off pattern, I’ll set a one-bar loop, slow it to about 50%, and count along until the timing locks in.

Can I change a song's key to one that fits my voice?

Yes. Yalaloop’s pitch control shifts the recording up or down in semitones, independently of the speed. If a song is recorded in a key that’s too high for me to sing along, I drop it 2 or 3 semitones, then practise the guitar part along with that pitched-down version. Speed and pitch are independent — slowing down doesn’t change the key, and pitching down doesn’t change the tempo.

Can I keep practice sections from one session to the next?

Yes. Loops, markers, and the speed/pitch settings you’ve used for each one are saved with the track. Open the file again and your work is right where you left it — no need to rebuild loop boundaries or re-mark sections every time. This is the gap that kept me hitting Save As… in Audacity.

Can I switch between songs without losing my place?

Yes. Each track in your library has its own loops, markers, and settings. Switch to a different song and back, and both retain everything. I keep half a dozen songs in rotation across a practice week and Yalaloop remembers where I was on each one.

Can I set up loops on one device and practise on another?

Yes. I set loop boundaries and adjust per-loop settings on my iPad because the bigger screen makes precise drag-select easier. Then I practise on my phone with the guitar in my hands — Yalaloop syncs my loops, markers, and settings between devices, so what I prepared on the tablet is right there on the phone when I open the same track.

How is this different from slowing down a YouTube video?

Yalaloop is purpose-built for practice; YouTube’s speed control is a viewer convenience. The differences that matter for a guitarist:

  • Sample-accurate loops with a short crossfade — no jump-cut click on every wrap.
  • Independent speed and pitch — drop the tempo without raising the key.
  • Per-track memory — your loops and settings are there the next time you open the song.
  • Files you actually own — works with the audio in your library, not just YouTube uploads.

What audio formats work?

Yalaloop plays whatever your device natively supports — MP3, AAC, FLAC, WAV, M4A. Files in your music library or accessible via the Files app (iOS) or local storage (Android) all open.
