ZettaMic vs Voice Amplify

ZettaMic is a helper application for Zetta2GO. Which is used in conjunction with Zetta by RCS. ZettaMic will record audio and send it to the user's main Zetta site.

Voice Amplify turns your iPhone into a simple personal sound amplifier. It listens through the microphone and plays what it hears back louder through the speaker — in real time. If a family member speaks softly, a conversation is too quiet, or a speaker is far away, just tap Start and hear it louder. Due to audio feedback, it works best when speaker speaks slowly. Designed to be genuinely easy for everyone to use, with big, clear controls. WHY YOU'LL LIKE IT • One giant Start/Stop button — no menus, no setup • Simple Loudness slider to set how much to amplify • Built-in feedback reduction to prevent squeal and howling • Adjustable delay to keep the sound clear • Works with the built-in mic, or a wired/Bluetooth microphone PRIVATE BY DESIGN • No account, no sign-in • Audio is processed live and is NEVER recorded, saved, or sent anywhere • No data collected, no ads, no tracking • Works completely offline TIPS FOR THE BEST RESULTS • For the clearest sound with no feedback, use earphones or earbuds (wired or Bluetooth) for listening • If you hear a squeal, keep "Reduce feedback" on, lower the Loudness a little, or increase the Delay • Start with a lower volume and raise it gradually Voice Amplify is a general-purpose amplification tool for everyday convenience. It is not a hearing aid and is not a medical device. If you have concerns about your hearing, please consult a qualified audiologist or healthcare provider. Free. No subscription, no ads, no in-app purchases.
