How AI Music Generation Works

Create original music in three simple steps. No musical knowledge required.

Step 1

Describe

Write a text prompt describing the music you want. Mention genre, mood, instruments, tempo, and style. Use the quick-select tags to build your prompt faster.

Step 2

AI Composes

The AI model analyzes your prompt and generates original music. GPU-accelerated processing ensures fast results, typically 10-30 seconds depending on duration.

Step 3

Download

Preview your generated music with the built-in audio player. Download in WAV format for maximum quality. Regenerate with different settings until you get the perfect track.

Frequently Asked Questions

AI music generation uses deep learning models to create original music from text descriptions. Describe the style, mood, instruments, and tempo you want, and the AI composes a unique piece of music. No musical knowledge required.

TTS.ai is powered by ACE-Step v1, a 3.5-billion-parameter diffusion-transformer model released under Apache 2.0 with no gated dependencies. It generates 48 kHz stereo audio in 17 languages from text prompts and optional lyrics. We chose it because it's the only fully permissive music model that ships today without a Llama or Gemma backbone restriction.

Yes. ACE-Step is Apache 2.0 — both the model code and weights — so all music generated through TTS.ai is yours to use commercially. You can use generated music in YouTube videos, podcasts, games, ads, and any commercial project without royalties or attribution.

Free accounts can generate up to 30 seconds. Pro and Business plans unlock the full 240 seconds (4 minutes) per generation. Even at the longer durations, generation typically completes in 30-60 seconds on our A100 GPUs.

Yes. Describe your desired genre (rock, electronic, jazz, classical, lo-fi, ambient), mood (happy, sad, energetic, calm), instruments (piano, guitar, synth, drums), and tempo in the text prompt. ACE-Step interprets your description to generate matching music. Use the on-page genre and mood tags to build prompts faster.

Yes. ACE-Step v1 supports an optional lyrics field. Provide your lyrics (up to 4,000 characters) along with a style description and the model will generate a complete song with vocals. Lyrics are supported in 17 languages including English, Spanish, French, German, Chinese, Japanese, and more.

Generated music is output in 48 kHz WAV format for maximum quality. The API also supports OGG output. You can convert to MP3, FLAC, or M4A using our free Audio Converter tool.

ACE-Step is a diffusion transformer that uses Sana's Deep Compression AutoEncoder (DCAE) for audio encoding and a lightweight linear transformer for conditioning. It generates audio in roughly 27 diffusion steps, achieving 27x real-time on an A100 — a 4-minute song renders in about 20 seconds.

Yes. AI-generated music from TTS.ai is original content created on demand. It won't trigger Content ID claims because it's not a copy of existing music. You can monetize videos using this music without copyright issues.

Music is priced by duration: 200 characters per second of generated audio. A 30-second clip costs 6,000 characters; a 4-minute song costs 48,000. Free accounts receive 15,000 characters on signup, enough for several short clips. Paid plans start at $5/month for 200,000 characters.

Yes. Our REST API exposes /api/v1/music/ for authenticated users. Send a JSON body with prompt, duration, and optional lyrics; receive a job UUID to poll for the generated audio URL. Available on all paid plans.
