# IronSound

> IronSound turns one prompt into a finished AI song with vocals + lyrics. 10 free credits on signup. Full song 10cr, 30s clip 1cr, studio WAV master 20cr. Custom lyrics and regenerate supported. Private library with MP3/WAV download and a per-song license you can keep with the file, plus stems and a streaming master on full songs and studio WAVs (not 30-second clips). Vocals and drums are separated; bass and other are derived reference tracks, not separated stems. Full songs are made with YuE2-3B, self-hosted on IronSound-operated servers, when that engine is available; otherwise they fall back to Google Lyria 3.5. 30-second clips use Google Lyria 3 Clip, and studio WAV masters use Google Lyria 3.5. Lyria output carries an inaudible Google SynthID watermark; YuE2-3B output does not. Each song's license file names the engine that made it. Commercial use per the per-song license; no artist-voice clones or unowned copyrighted lyrics.
