FAQ
How does Capfuse split songs into stems?
Capfuse uses an AI model to automatically separate imported tracks into four stems: vocals, drums, bass, and 'other' (which includes instruments like guitars and piano). This process runs on import and is available for free.
Can I export my finished mashups as audio files?
Currently, Capfuse does not support audio export. Separated stems and finished mashups play back within the app's built-in library and cannot be saved as external files.
