The client approached us with a bold vision

Build a web-based platform that can use music stems to allow dynamic audio creation and personalized MP3 generation for users

Here were the key challenges they were facing:

  • Real-time audio stem mixing: Enabling users to preview seamless combinations of different audio tracks.
  • Variations UI/UX: Designing a user-friendly interface for selecting and mixing different stem variations.
  • MP3 file generation: Rendering a downloadable audio file based on user selections.
  • Payment integration: Ensuring a smooth, secure process where users pay before downloading their creation.
  • Audio rights and usage protection: Preventing file downloads before payment.

Our Solution

We broke the project down into key milestones, each focusing on solving a core part of the platform’s functionality

Features Implemented

1. Interactive Audio Stem Mixer

  • Built a dynamic web audio player that handles multiple stem tracks.
  • Implemented layer toggling so users can play/pause and switch stem variations in real-time.
  • Used the Web Audio API for precision control over stem synchronization and layering.

2. Clean and Intuitive UI/UX

  • Designed a variation selection panel to allow users to choose stems from various categories (e.g., vocals, drums, bass).
  • Added real-time previewing, enabling users to instantly hear the result of their changes.
  • Created animated transitions and waveform visualizations to enhance user engagement.

3. Audio Generation & MP3 Export

  • On the backend, built a custom audio processing pipeline that:
    • Takes selected stems.
    • Merges them into a final audio file.
    • Converts and compresses the mix into a downloadable MP3.
  • Ensured high-quality output and server-side rendering to prevent unauthorized access.

4. Stripe Payment Integration

  • Integrated Stripe Checkout for secure payment handling.
  • Users must complete payment before generating their custom track.
  • After successful payment, the user is granted access to generate and download the MP3.
  • Built a token-based download system to prevent abuse.

5. User Session Management

  • Developed a simple user session flow:
    • User selects and mixes stems.
    • Initiates payment via Stripe.
    • On payment success, backend saves the selection, renders the MP3, and activates the download link.
  • Ensured that sessions are temporary and reset if users refresh before purchase (to avoid caching unpaid work).

Technologies Used

  • Frontend: HTML/CSS, Bootstrap
  • Backend: WordPress / Laravel
  • Payments: Stripe API
  • Storage: AWS S3 for temporary audio file storage

  • The secure, paywall-controlled generation system ensured proper digital rights protection for music files.
