Hear the current pace before you record.
The raw microphone recording stays separate from the app-generated click. Headphones are recommended. If the phone speaker is used, the microphone can physically hear the click, so turn the metronome down if needed. In 6/8, beats 1 and 4 are accented.
Test the microphone before recording when permission or input is uncertain.

Automatic key stays the main quick answer. These are the next strongest matches from the same recording. Hear any choice with your song, then use it only if it sounds right.
Confirm key by singing the 1 / root
First sing or hum the note that feels like HOME — the 1. The app then checks the recording for Major vs Minor. If they are too close, sing the 3 to settle it.

Fine tune exact trim times
Saving the trim creates a shorter WAV working copy. A one-step original-audio safety copy is kept in this browser so the trim can be reversed.
Creating timed lyrics automatically
No choice is required. After trimming, the app tries the free local model and can use the secure online fallback when it has been configured.
STEP 3
Waiting for the trim to be saved.
If the words cannot be understood, the recording remains safe and the numbered lyric checkpoint section opens empty for manual tagging.
EASIER LYRIC FALLBACKSpeak the lyrics clearly instead
🎙
Read the words normally instead of singing. This creates an editable lyric draft without replacing your original recording.
Tap once, speak the lyrics from beginning to end, then tap Stop and create lyric draft.
The lyric times will be approximate. Drag the numbered markers afterward to match the original sung recording. Browser speech recognition may require internet access.
You can also play the recording and tap the numbered checkpoint button as each lyric begins, then type the words.
Finish after every lyric has words and a correctly placed checkpoint.
