Audio player in the PDF viewer (with loop and tempo)

What is this?

The audio player in the PDF viewer plays audio examples for the current piece directly under the sheet music. With the tempo control and the loop range you can practice difficult passages slowly in a targeted way — all without leaving the score.

Use

1. Open the PDF in the Sheet music tab
2. Tap the audio icon in the toolbar
3. Choose a file from the list — all audio files assigned to the piece
4. Tap play — the player appears with controls

Features

• Tempo control 50-200% — practice slower, pitch is preserved (time-stretch)
• Loop — defined range (start + end marker) is repeated endlessly
• Skip controls — forward/back by 5 or 10 seconds
• Volume can be set independently
• Pitch shift (optional, if the file allows it)
• Background playback — audio keeps playing with the app in the background

Make your own recordings

Anyone who can edit sheet music can record directly in the audio player — for example a rehearsal recording or a practice take of their own voice:

1. Tap the microphone icon in the audio player — recording starts right away
2. Page turning stays available — you can keep using the sheet music while recording, a small indicator shows the elapsed recording time
3. Tap stop — you listen to the recording first, at your own pace
4. Name it and save — only then is it uploaded and visible to all members. Or discard it if it did not turn out well.

Recordings can be up to 60 minutes long. To delete one, tap the trash icon next to the file — with a confirmation prompt.

When is it useful?

• Practice at home — sing your voice along with the audio example
• Slowly learn a difficult passage — reduce tempo to 60%, drill it, gradually increase
• Loop for repetition — e.g. play a chorus over and over
• Hear pronunciation precisely — for foreign-language texts, play slowly
• Get used to the original tempo — listen ahead of the rehearsal

Tips

• Bluetooth headphones for distraction-free practice
• Use the loop instead of rewinding manually — set markers, the app does the loop
• Increase tempo step by step — 60% > 70% > 80% > ... > 100%
• Add multiple audio files — original + slow practice version
• With tempo distortion — turn off pitch shift, then sound quality stays better
