Shapes what comes out of your earbuds inside this app. Applied to exports too.

Limiter ceiling, in dB. Keeps loud takes from clipping on export.

Bluetooth mics drop to phone-call quality (8–16 kHz) and add 100–200 ms of delay. That's Android, not this app. Use a wired USB-C mic for takes; Bluetooth earbuds are fine for listening back.

I'll walk you through writing your own song, one piece at a time — questions, rhyme ideas and cadence checks, never a finished song for you.

Freeform space. Not part of the guided coach above — just quick syllable/rhyme/title tools.

Worksheets built from whatever is in the lyrics box above. Saves a PDF you can print.

Turns your lyrics plus a note list into the same PDF sheet we make together. One note per syllable, separated by spaces. Use ^ for the higher octave, e.g. A^ D D F^ E

Paste a key to turn on Generate and the coach's "Ask my coach" hints. It is saved on this device only, never synced, and never shown on a student profile.

No key saved.

Without a key, the syllable counters, rhyme checks and coach tips above still work offline.

Each instrument arrives as its own track, so you can mute, rebalance, or delete any of them. Made in the app, offline.

Tap and hold a key to play it — like a real keyboard. Colours match Raevyn's keyboard stickers. Your computer keyboard works too: A S D F G H J K L for white keys, W E T Y U for black keys, Z/X to shift octave.

Nothing recorded yet.

Ready-made clips in your current key and tempo. Imported loops are stretched to match your session tempo automatically — tap a loop's name to correct its BPM if the guess is wrong.

Free loops, no payment anywhere on these:
Pixabay — loops · no account, no credit needed, nothing paid on the site
Pixabay — music · same, full tracks
Freesound — CC0 only · free account to download, nothing is ever for sale
These two are the whole list on purpose. Other sample sites mix free and paid together, and it is far too easy to end up at a checkout.

Download, then Import loop files. Put the tempo and key in the filename — gtr Dm 103.wav — and it fits itself to your session.

A backup carries profiles, lesson log and loops. Send the file to another device and Restore it there — that is how you and Raevyn share the same setup.

Tap the grid to place notes. Colours match Raevyn's keyboard stickers.

Pulls the centre of the stereo image apart. Works on most produced stereo tracks; does nothing useful on mono.

This is centre-channel subtraction, not machine learning. Expect artefacts and some bass loss. For clean stems use Demucs.

Uses only loops from your own library. It lays out options — you pick one, then rework it.

Hum or sing a melody, then read the note letters back. Colours match your keyboard stickers.

Generate a full track from your lyrics in the Gemini app with Lyria, download it, then bring it in here with Import File and edit it like any other clip.

Loudness is measured from what's playing, so hit Play mix first.

Width past 100% pushes the sides out. Keep bass and lead vocals near the middle.

-14 LUFS suits streaming. -9 to -11 is louder and more aggressive. Nothing here is sent anywhere.

Tap along plays the mix and you tap once per line. That way the words land where you sing them.

Plays the whole song and captures it. Leave the screen on and don't switch apps. Saves a .webm you can upload straight to YouTube, TikTok or Reels.

Everyone who opens this link shares the same profiles, lessons and progress. Nothing to set up.

Checking…

Connects your phone and Raevyn's laptop through a free Supabase project. Set it up once on each device with the same three values.

Not set up yet.

Badges are earned for things done, not points.

Short lessons that use the studio itself. Read it here, or print it as a worksheet.

Grade 6 expectations, summarised in plain English with the official codes so you can check any line against the ministry document. Tap a box to cycle: not started, working on, met.

Add anything done away from the studio so it lands in the same report.

A printable PDF summary — level, streak, badges, and the skills practiced along the way. Good for a homeschool portfolio.

Import a song you own (Battle uses whatever audio you bring — nothing built in), or challenge one of your own takes.

Plays your opponent, you sing along on the mic — the app scores how closely your pitch tracks theirs.

The opponent track plays — tap the button in time with the beat. Closest average timing wins.
