∿ What you see is what you hear ∿∿∿

★ (NEW!) You can also record up to 15 seconds of audio and render it into a neat, easily shareable video file. ★

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.

Great and fun app

This is really cool if you're an engineer or geek. Well worth $.99..

I'm sure the iPhone's mic has a certain frequency range, but does it really cutoff at 100hz? Would be nice if it could go lower, preferably down to 20 or so hz, which I'm sure the mic isn't capable of. Maybe with an external mic the scale could shift down to 10hz?

Please make it as low as possible!

Very useful

Quite useful to capture oscilloscope waveform videos for synthesizer videos, except it only records 14 second videos ... I was looking for an IAP for longer videos immediately, but couldn't find one.

Great app

I always wanted a spectrum analyzer and am really pleased with how this performs. It has helped me track down some resonances in our auditorium. I don't run sound without my iPad handy now.
