Soundbeam helps you see what everyday sounds look like and visualizes sounds you can't even hear!

Plug in your electric guitar, a mic or any other (hi-Z) device to your mini-jack input and get accurate measurements. You can always use the built-in mic.

We paired stylish controls and an old-school interface with high precision signal processing algorithms, creating a new way to experience sound.

Soundbeam is an real-time audio analyzer (RTA) that processes the input of your microphone displaying it like a classic oscilloscope. It also features a spectral visualization of the audio using high resolution fourier transform (FFT) for accurate measurements.

Get a dose of nostalgia with Soundbeam now!

Simply stunning!

I've just downloaded and testing in my kitchen, pics up the fridge, boiler in the corner all very low 80Hz range even the built in mic is very good, amazingly realistic look , whoever wrote this app is very cool, all those other expensive oscilloscope app developers are going to fall over backwards! I personally feel like I owe you money! You mean to tell me the headphone socket can be used as a mic input?.. On the ipad2? Will test asap, there is an Alesis IO Dock but driver support isn't very good. Thank you!

Mind blowing!

On the built in mic or combined with the iRig plugged straight into the source, this app is superb! The elegant interface effortlessly showcases all the beauty of wave forms and the joy of modifying them on a synth. While competing oscilloscope apps are charging up to fifty quid, this has been my best app store purchase yet and it was free! Thank you!

for 69p it is a no brainer

I have got so much use out of this in the 2 days since I bought it, and for 69p nowadays that isn't bad at all. Very limited, obviously, but as a cheap waveform visualizer it really is very useful.
