Weav is designed to make music sound “awesome at any speed”.
Lars Rasmussen, co-creator of Google Maps and former Facebook employee, has unveiled an interactive music format that allows artists to create tracks whose tempo can be manipulated without affecting the quality of the song.
Developed by his fiancé Elomida Visviki, Weav lets artists and listeners freely play with tempo. It does this by allowing musicians to record different elements of a song suitable for playing at different speeds, which lets the listener shift the BPM up or down while blending the audio.
“Artists can specify how the track should change and develop as the tempo is increased or decreased, opening up tremendous new creative possibilities,” says the project’s website. “The artist controls the composition, changing the experience depending on the playback speed chosen by the listener.”
Possible applications for Weav include linking it to an exercise app that could respond to the body’s heart rate with an appropriate song tempo.
Though applications like Ableton Live have previously been able to change the tempo of songs while keeping the musical key intact with their own time-stretching methods, it affects the quality of the sound drastically. Weav prevents that – but only if artists use the proprietary mixer for creating tracks and listeners uses the Weav player.
