Ear Assist: Sound Amplifier

This update fixes several things that were not working, and adds more control over how you listen. FIXED • Recording works again. Recordings were not being saved in versions released since mid-2025. They now save correctly, as M4A files. • The volume slider now changes the volume. Before, it moved the level meter but not the sound. • The equaliser keeps working after you stop and start listening, the 14 kHz band now has its own slider, and loading a saved configuration now changes the sound. • Bluetooth headphones no longer drop to phone-call sound quality when the app starts. NEW • Boost: add +6, +12 or +18 dB when listening through headphones. It is switched off on the loudspeaker, where it would cause feedback, and limited on the earpiece. • Speech mode: uses Apple's voice processing to reduce background noise and echo. Natural mode stays the default, for music, birdsong and ambience. • On iOS 26, choose your microphone from the system input menu. REMOVED • The AEC, AGC, NS and VR buttons. They did not change the sound. Speech mode now does what they described. A NOTE ON DELAY Live listening through headphones always has a short delay. It is shortest with wired headphones; Bluetooth adds more. Thank you for sticking with Ear Assist.
