What is Song Do?
Song Do is an AI‑driven voice synthesis platform that creates realistic singing performances from text and melody input. Built on deep‑learning models trained with thousands of hours of vocal recordings, the service can produce expressive, genre‑appropriate vocals without the need for a human singer or a recording studio. The result is a practical tool for anyone who needs high‑quality vocal tracks quickly—whether you are producing a commercial pop single, scoring a short film, or experimenting with new musical ideas.
Core Features
Voice Generation
Song Do converts written lyrics and a simple melody line into a full‑featured vocal track. The engine supports a range of vocal timbres—from bright pop leads to warm jazz tones—allowing you to match the voice to the style of your composition.
Customization Options
- Pitch & Range – Adjust the singer's key, octave, and vocal range to fit your arrangement.
- Expression Controls – Modify vibrato depth, breathiness, and dynamics to convey emotion.
- Articulation Settings – Choose between legato, staccato, or a more conversational delivery.
These controls let you shape the performance as precisely as you would with a human vocalist.
Integration Capabilities
Song Do exports stems in WAV or AIFF format and provides a VST/AU plugin that can be loaded directly into popular DAWs such as Ableton Live, Logic Pro, and FL Studio. A REST API also enables automated batch processing for larger projects or integration into custom production pipelines.
Collaboration Tools
A web‑based project board lets multiple users share lyric drafts, melody sketches, and versioned vocal renders. Comments can be attached to specific timestamps, streamlining feedback between songwriters, producers, and engineers.
How It Works
Input Process
- Upload or Record a Melody – Import a MIDI file, audio clip, or simply hum a tune into the browser.
- Enter Lyrics – Type or paste the full set of lyrics; the system automatically aligns them to the melody's rhythm.
- Select a Voice Profile – Choose from a library of pre‑trained vocal personas (e.g., "Pop Female – Bright," "Male R&B – Smooth").
Technical Details
Song Do's core engine combines a transformer‑based text‑to‑sing model with a neural vocoder. The text‑to‑sing component predicts pitch contours, timing, and phoneme articulation, while the vocoder renders the final waveform with high fidelity. Continuous training on diverse datasets ensures the model captures subtle nuances such as phrasing, breath placement, and genre‑specific ornamentation.
Refinement Loop
After the initial render, the interface displays a waveform and a piano‑roll view. Users can drag notes, adjust timing, or re‑apply expression sliders. Each change triggers a rapid re‑synthesis (typically under 10 seconds), allowing an iterative workflow comparable to editing a recorded vocal take.
Use Cases
Music Production
A pop producer can generate a full vocal hook in minutes, audition multiple voice styles, and settle on the best fit before committing to a live singer. For example, a producer working on a summer anthem might start with a "Male Pop – Energetic" voice, tweak the vibrato for a more relaxed feel, and export the stem directly into the mix.
Composition & Songwriting
Songwriters often struggle to hear their ideas fully formed. With Song Do, a composer can input a chord progression, hum a melody, and instantly hear a sung version, helping to evaluate lyrical flow and melodic strength without arranging a full band.
Film & Game Audio
Indie developers can create character songs or background vocal loops without hiring session singers. A game studio might use the "Fantasy Female – Ethereal" voice to produce a short in‑game chant, adjusting the breathiness to match the scene's atmosphere.
Accessibility & Education
Music educators can demonstrate vocal techniques (e.g., legato vs. staccato) by toggling expression controls in real time. Students without access to a vocal coach can experiment with different singing styles and receive immediate auditory feedback.
Advantages
Quality and Realism
The AI model captures natural phrasing, dynamic variation, and subtle timbral shifts, producing vocals that blend seamlessly with human‑recorded instruments. Listeners often cannot distinguish Song Do's output from a professional singer's performance.
Speed and Cost Efficiency
A complete vocal track can be generated in under a minute, eliminating studio booking fees, travel expenses, and the time required to schedule a vocalist. This accelerates project timelines and reduces overall production budgets.
Flexibility Across Genres
Because each voice profile is trained on genre‑specific data, Song Do can deliver appropriate articulation for pop, rock, jazz, classical, and even niche styles like K‑pop or Afro‑beat. Users can switch profiles mid‑project to experiment with cross‑genre arrangements.
Seamless Workflow Integration
The VST/AU plugin and API mean Song Do fits naturally into existing DAW sessions. Producers can replace a placeholder vocal with a final AI‑generated track without leaving their preferred environment.
