## What is Earform?

Earform turns a mix comparison into a repeatable listening test. Import two audio exports from Files, listen to known A and B, then decide which one the hidden X matches. The answer stays hidden until the final trial. Choose five, eight or ten trials and keep an optional note for each choice.

Switch A, B and X at the same playhead position, adjust the B start offset when files begin at different moments, and optionally attenuate the louder file using measured RMS signal energy. RMS matching is not LUFS or perceptual loudness matching.

The result shows every hidden source and answer, correct count, and the exact one-sided probability of that score or higher from independent 50/50 guesses. Preview and share a PDF report. Saved tests and imported audio remain on your device. A user-triggered original sample lets you try the full workflow.

Supports audio formats that iOS can decode, up to 20 minutes and 500 MB per file. This is a listening decision aid, not an audio-quality rating or proof that two sounds are equivalent. No account, subscription, ads, analytics, tracking, cloud sync, or developer-server upload.
