Build an Online Karaoke Singing App

Karaoke apps are a hit among music lovers and casual singers. Building one gives you experience in audio mixing, real-time lyrics synchronization, recording features, and file handling. This app development project is perfect for merging creativity with multimedia technology.

Users can choose songs, sing along while reading on-screen lyrics, record their voice over the instrumental track, and save or share their performances. Additional features like duet mode, pitch correction, and applause sound effects make the app more fun.

The user picks a song and starts singing while the backing track plays. As lyrics scroll in sync, the app records their voice. After the performance, the app mixes the voice with the background music and creates a final audio file that can be saved or shared.

• Browse or search karaoke tracks and choose a song to perform.
• Sing along while the lyrics display on-screen with real-time sync.
• The app records the user's voice while the instrumental track plays in the background.
• After completion, the audio is processed into a single output file with mixing and basic enhancements.
• Users can play back, save, or share their recording via social media or cloud storage.
