Sound Amplifier: Ear Booster のアプリ分析 11月1日

Sound Amplifier uses your phone's microphone to pick up the sound around you, makes it louder and clearer, and plays it straight into your headphones. Follow a conversation in a noisy café, hear the TV without turning it up for everyone, or catch every word of a lecture you are attending. HOW IT WORKS 1. Connect wired, USB or Bluetooth headphones 2. Tap Start listening and allow microphone access 3. Pick a sound mode, then raise the boost until voices are comfortable 4. Lock the screen if you like: listening goes on until you tap Stop FEATURES • Headphones only: never plays through the phone speaker, so no feedback whistle • Boost up to +30 dB and left / right balance • Instant replay: missed a word? Hear the last 10 seconds again, then live sound comes back • Speech focus: lifts voices while someone talks and lowers steady background sound between words • Handling noise guard: softens the thump when you touch or move the phone • Safe-listening limit: set a max loudness and a max boost, and see an estimate of today's loud listening time • Noise reduction, loud-sound comfort and a feedback guard • Sound modes: Natural, Conversation, TV, Lecture and Nature • Four microphone modes and named scenes, such as Home or Restaurant • Keeps running with the screen off; Quick Settings tile • Reminder to rest your ears; stops by itself during calls PREMIUM • Unlimited listening (free sessions last up to 10 minutes) • 8-band custom EQ from 250 Hz to 8 kHz • Personal sound profile: a short tone check per ear that tunes the sound for your left and right ear. It is a comfort setting, not a medical test • Save clips of what you are listening to, and share them later • Instant replay of the last 30 seconds, saved as a clip with one tap • Choose the speech focus strength • Unlimited scenes, plus Far away and Raw microphone modes Monthly, yearly or one-time lifetime purchase, billed by Google Play. Cancel any time. PRIVACY Sound is processed on your phone in real time. It is never uploaded. Instant replay keeps the last 30 seconds in memory only, and nothing is saved until you tap Save. Analytics and crash reports never receive audio and can be turned off in Settings. PERMISSIONS • Microphone: asked when you tap Start • Notifications (optional): shows a Stop button while listening SAFETY Sound Amplifier is not a medical device and does not replace professional care. Start with your phone volume low and raise it slowly: loud sound over time can damage your ears. Take breaks. Do not use it to listen to or record other people without their knowledge. No account. No sign-up. No ads while you listen.
