AstraTune, a Local-First Vocal Studio in the Browser
AstraTune lets singers and rappers correct pitch, build harmonies, shape melodies, and export vocal projects from a browser-based studio.
Field notes
The documented workflow starts with a microphone, imported isolated vocal, or synthetic demo, then applies key- and scale-aware correction while keeping the source take separate. Its more unusual modules include Choir Geometry, which adds two transposed voices with stereo positioning, and Phrase Compass, which offers three local melodic transformations based on musical rules rather than a remote model. Exports are described as 24-bit WAV files or editable .astratune projects.
