Amplitude enhances aural experiences by allowing you to hear distant and/or quiet sounds as if you were standing nearby. Amplitude uses the high quality hardware of the iPhone and iPod Touch* to detect and amplify the faintest of sounds. ***Note: To get the best experience possible, you must use earbuds that do not have a built-in microphone.***

Amplitude lets you adjust the sensitivity of the iPhone microphone to amplify sounds from across a room. You’ll hear things you never would have been able to hear otherwise.

Using Amplitude is easy: simply launch the app, point your device in the direction of the sound you want to amplify, and starting hearing the world in a new way through your headphones. Individual controls enable you to adjust the microphone sensitivity or mute the sound amplifying feature altogether.

Use Amplitude to explore your world. Experience all the sounds of your environment that you would otherwise have missed.

Experience Nature and Wildlife More Intimately

- Have you ever heard the sound of a hummingbird’s wings beating back and forth? It’s pretty interesting to hear even with unaided ears. Using Amplitude, it’s a truly amazing experience.

Experimenting Around Your World

- Listen to your heartbeat for the first time

- Diagnose the source of that annoying squeak in your new car.

- Attach a cup or small plastic bowl to the end of your iPhone to focus the incoming sound and expand your range

- Place microphone against a office wall to hear sounds from all over the building.


At Sporting Events

- Baseball: Listen to the first base coach, the players in the dugout and the player in the batting circle.

- Golf: Hear golf pros discuss the next shot with their caddy.

Amplitude Benefits:

- Turns your iPhone or iPod Touch* into a sound amplifier

- Hear sounds through thin walls or doors

- Adjustable microphone sensitivity / boost

- Adjustable volume and mute controls

- Independently control the iPhone volume and the microphone sensitivity

- View sound waves on the oscilloscope

*Ear buds are required for use with all devices. Use with the iPod Touch requires a headset with built-in microphone feature.

Tips on Using Amplitude:

- For best audio reception, point the microphone in the direction of the sound you want to pick up.

- Amplitude controls are oriented upside down from other apps so that the microphone can be pointed toward target sounds.

- To protect against accidental ear damage, Amplitude starts in Muted mode. The “Mute at Start” feature is configurable in the Info screen.

- We recommend keeping device volume between 50-75%.

- Experiment with microphone sensitivity. Some situations will require more, some less.

- To preserve battery life, launch the application and press the device sleep button to darken the screen.

- You can maximize your reception by using your hands or a plastic cup to focus the incoming sound. This is the best method to use when listening through solid objects like doors or walls.

- Like any exposed microphone, the iPhone microphone is sensitive to wind noise. For best results we recommend using Amplitude in non-windy situations.

- Experiment with different attachments and microphone settings and let us know what works best for you.

Pros and cons of Amplitude app for iPhone and iPad

Amplitude app good for

Just got this app. It sounded like it was going to be a lot of fun to use, and it is. It looks very cool...nice graphics, and couldnt be easier to use. It caught the sound of some birds in my backyard, and some kids playing outside. I just played with the settings and volume and was able to hear things that were far away. Nice job!
I was a little skeptical at first, sounded too awesome to be true. But once i downloaded it, it worked just like they promised and i found so many great uses for it... i can have my friends whisper the answers on tests! Its just great, worked better then i expected. Also the graphics are very good, clean and simple to use.. just the way i like it!
Fun and easy to use, it really does help me hear interesting sounds I wouldn’t otherwise notice. A great app to help adults and kids become more aware of whats happening around them. Easily worth the fee.
This totally helped me hear things that Im sure others wished that I hadnt! Can get a little loud at times, but hey, thats what its supposed to do, and is easliy controlled. Very fun to play with.
Think of this as a preamp for the iPhone microphone. Im a musician and Ive actually made some cool recordings using this app, by patching the headphone out into a recorder. The iPhone mic is a bit limiting in terms of low frequencies, but this is not Amplitudes faul. My only wish is that the signal didnt get so noisy on the more sensitive settings. Great app though! Nice work.
This application is absolutely amazing. I was able to use it in the lecture hall to hear the guy talking who didnt have a microphone. Fabulous product!

Some bad moments

It only amplifies local sounds and even that with a lot of white noise. It doesnt work as advertised, dont waste your money.
I have a new iPod touch, and Amplitude doesnt work at all! Maybe I misread the devices it is supposed to work on, but it sure doesnt work on mine.
Works well ish had a few proba though gettin it 2 wurk 50-50tht it works on iPod I had troubles with it....
I hated this thing. It was very awful..usually everything i buy on the apps work but this didnt. I couldnt hear nothing! Im very dissappointed with this!
Waste of money. As reported by others it seemed to lower the volume in the room. I wasnt even able to hear my own heartbeat with it. FAIL!!!
worst app ive downloaded!! glad it was only 99cents didnt even pick up my cat meowing save your deniro
