Phase 4: Audio & Music Generation · 50 min · Python · Suno API · ElevenLabs API

Audio Generation API Integration

Suno for songs, Stable Audio for SFX, ElevenLabs for commercial music, MusicGen for local — programmatic audio generation across providers.

Real-world application: Audio API integration across multiple providers (Suno, Stable Audio, ElevenLabs, MusicGen) demonstrates multi-provider engineering skills for audio generation.

What you will learn

Integrate Suno API for programmatic song generation with style and lyric control
Integrate Stable Audio API for instrumental and SFX generation
Integrate ElevenLabs Music API for commercially-licensed music
Use MusicGen via Hugging Face Transformers for local inference

Objective

Generate listening samples and evaluate them for structure, fidelity, editability, and intended use. In the paired studio lab, build an audio generation router that routes requests to the right provider based on use case: full song with vocals → Suno, commercially-licensed music → ElevenLabs, instrumental → MusicGen. Include cost tracking and fallback logic.

The Problem

A team needs to integrate audio generation into their product. They need:

Full songs with vocals for user-generated content → Suno API
Background SFX for video → Stable Audio API
Commercially-licensed music for paid features → ElevenLabs Music API
Local inference for cost optimization → MusicGen via Hugging Face

Each provider has a different API pattern. The team needs to integrate all four and route requests to the appropriate provider based on use case.

What you'll build
Integrate four audio generation APIs: Suno (songs), Stable Audio (SFX), ElevenLabs (commercial music), and MusicGen (local). Build a unified audio generation interface that routes to the correct provider.
