Syncing Animations to Music

Learn how to sync your servo movements to music and audio tracks in Bottango.

One of Bottango’s most powerful features is the ability to synchronize your animations with music or sound effects. This is perfect for building animatronics that lip-sync, dance, or react to music in time.

🎵 Step 1: Add an Audio Track

1. Open your Bottango project.
2. In the timeline view, click Add Audio.
3. Choose a .mp3 or .wav file from your computer.
4. The audio waveform will appear in the timeline.

📝 Tip: Use short, high-quality audio clips for best results.

🕒 Step 2: Align Keyframes with the Beat

1. Play the audio using the timeline preview.
2. Use the waveform as a visual guide to place keyframes at musical beats or lyric changes.
3. You can zoom in on the timeline for precise placement.

This makes it easy to time head nods, arm waves, or jaw movements with music.

🗝️ Step 3: Lip-Syncing Basics

To create a simple lip-sync effect:

• Assign a servo to control the jaw or mouth
• Create quick up/down movements at syllables or beats
• Use easing curves to make the motion look more natural

For more realism, try animating multiple mouth positions (visemes) using multiple servos.

🎛️ Optional: Use Audio Triggers

If you want animations to start when audio begins, create a trigger:

1. Go to the Triggers panel.
2. Choose Audio Starts as the source.
3. Set the action to Play Animation or Start Timeline.

You can also sync lighting, gamepad actions, or other animations using audio events.

🔊 Output Options

• Bottango plays audio on your computer, not on the microcontroller.
• If you’re using a Bluetooth speaker or need tight timing, test playback latency.
• For installations or stage performances, consider routing audio and animation output through a synced show controller.

🎭 Example: Dancing Robot

1. Load a short music clip (e.g. 10–30 seconds).
2. Add servo keyframes to match the beat.
3. Add dramatic motions for chorus or breaks.
4. Use loop playback to rehearse and refine.

The result? A robot or puppet that dances in time with the music — great for stage props, Halloween decorations, or interactive art.

You’ve now learned how to animate with rhythm and sound — awesome work!
