SpeakerEject

SpeakerEject provides free audio tools that run in your browser without an app installation or microphone access. Check speaker and headphone output with listening references, generate tones and frequency sweeps, and download original 5.1 and 7.1 channel-identification files. An optional water-eject tone is available for recent moisture near a phone speaker grille. Its effectiveness is unproven; it cannot repair hardware damage or remove dust. Listening tests are not calibrated measurements, hearing tests or hardware diagnoses.
