Phase 4: Audio & Music Generation · 50 min · Python · Suno API · Hugging Face Transformers

The AI Music Generation Landscape in 2026

Suno for songs, Udio for production control, MusicGen for open-source, Stable Audio for SFX — the audio landscape is as diverse as video.

Hiring signal: Audio/music generation landscape knowledge demonstrates breadth in generative media — it's tested in roles that require multi-modal pipeline engineering.

What you will learn

Compare Suno v5.5, Udio v1.5, Stable Audio 3, MusicGen, ElevenLabs Music, Mubert, and open-source models
Understand the difference between text-to-audio (SFX) and text-to-music (full songs)
Map the cost landscape: per-song $0.05–0.50 across providers
Choose the right audio model: end-to-end songs (Suno), production control (Udio), open-source (MusicGen), commercial licensing (ElevenLabs)

The Problem

A team needs background music for a product video. They default to Suno because "it's the most popular." Suno generates a full song with vocals — but they need instrumental background music. They don't know that Stable Audio is designed for instrumental/SFX generation. They spend time trying to prompt Suno to not include vocals, when a different model would have been the right choice from the start.

Audio/music generation landscape knowledge demonstrates breadth in generative media engineering. It's tested in roles that require multi-modal pipeline engineering.

What you'll build
A comparison tool that catalogs all major audio/music generation models (Suno, Udio, Stable Audio, MusicGen, ElevenLabs Music, Mubert) with their costs, strengths, and use cases. Generate a model selection guide.

Text-to-Audio vs Text-to-Music

These are fundamentally different tasks:

Category	Input	Output	Models
Text-to-Audio (SFX)	"rain falling on a tin roof"	Sound effect (3-47s)	Stable Audio Open, ElevenLabs SFX
Text-to-Music	"upbeat pop song about summer"	Full song (30s-4min)	Suno, Udio, MusicGen
Text-to-Speech	"Hello world"	Spoken voice audio	ElevenLabs, OpenAI TTS

Key distinction: SFX models generate short sound effects. Music models generate structured songs with sections (intro, verse, chorus). Using a music model for SFX wastes money and produces wrong output.
