Monofold checks a finished stereo audio file one second at a time. Its correlation tape highlights time ranges where the mono sum may lose level, so you can listen at the exact spot. Switch between the original stereo file and a real mono fold at the same playhead position. Import a file from Files, save local analyses, add handoff notes, and share a named PDF report with the generated 16-bit mono WAV. A clearly labeled workshop audio example lets you learn the workflow. Measurements are listening cues, not a mastering verdict or automatic repair. Confirm the result on your target playback system. Monofold works offline with no account, ads, analytics, tracking, cloud upload, or subscription.
