Lacuna: an AI audio studio
Lacuna brings music generation, songwriting, audio production, MIDI, and music visuals into one web platform for musicians, songwriters, and content creators. Start with an idea or work with an existing recording, then choose tools that fit the next step in your project.
Create songs and develop lyrics
The AI Song Generator creates songs with vocals or instrumental music through conversational Music Agent mode or a direct Custom form. Depending on the selected workflow, you can start from text, lyrics, images, audio, or MIDI references. Available controls and editing tools depend on the model and track.
The AI Lyrics Generator is a writing workspace with guidance for structure, rhyme, and style. Develop verses, choruses, and song ideas before moving into music generation. Dedicated pages cover inputs and occasions such as lyrics to song, image to music, birthday songs, jingles, and personalized song gifts.
Build around a melody
Hum to Song lets you record or upload a melody, review the detected MIDI notes, and use Lacuna Cadence to build a song around the confirmed melody. MIDI to Song starts with an uploaded MIDI file and a selected lead track. Sheet Music to Song begins with an image or PDF score and includes a melody review step; score recognition and song generation are priced separately.
Shape your audio
Depending on the model and track, Music Agent can help remix, extend, edit sections, split stems, tune vocals, transcribe MIDI, or master supported tracks on the canvas. The Stem Splitter separates selected vocals and instruments for listening, mixing, and export. Other tools include AI Mixing, AI Vocal Mixing, mastering, noise reduction, reverb removal, and voice isolation.
Lacuna also provides private singing-voice training, AI covers using official or trained voices, and songs with a voice from your library. Training is quoted before it starts. Song generation and voice conversion are separate operations.
Prepare visuals and work with MIDI
Create lyric videos, audio-reactive music visualizers, and album artwork to accompany a track. The LRC Generator provides editable lyric timing and subtitle exports, while Lyrics Extractor and Lyrics to SRT support transcription and video workflows.
MIDI Agent generates editable musical parts from a description. Preview and refine notes in the piano roll or through conversation. Everyday utilities also cover BPM and key analysis, pitch and speed changes, looping, MP3 tags, and audio conversion. Tools identified as browser-based process the relevant files locally; AI generation and cloud processing use server-side services.
Plans
Sign up for free monthly credits. Paid plans add more credits, audio downloads, and commercial-use rights for generated tracks. Downloads of AI-generated tracks require a subscription. Available controls, export options, and access requirements vary by tool and plan. See Lacuna's Pricing and Commercial License pages for current entitlements.
