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! Key Features: * Spectrum and waveform views * Recording functionality * Gesture support for frequency range and intensity levels adjustment * Visualization controls * ...and one more thing! Plug in your headset or guitar and watch what happens! Controls: * While in "spectrum mode", pinch the monitor vertically or horizontally to change frequency range and intensity levels respectively. You can also pan the soundwave with one finger. * In "waveform mode" pinch the screen vertically to adjust intensity levels. * Double tap on the screen to reset view. * Tap & slide the intensity knob horizontally to adjust it.

Awesome little oscilloscope!

This is a delightful app that functions as an oscilloscope for audio frequencies. I used an audio frequency generator (Function Generator Pro) on one device and plugged it into my iPhone via an audio cable and was able to view sine, square and triangle waveforms as if I were using an actual physical oscilloscope. I also built an electronic circuit to generate a sine wave and fed it into my iPhone via a Scarlett audio interface and that also worked wonderfully, showing the sine wave and frequency! The iPhone has a high-pass filter that cuts off anything over 10KHz, but for my projects that frequency was plenty high enough.Running an audio app and Soundbeam on my iPhone simultaneously showed me the waveform and the FFT-style spectrum analysis—the audio came out the speaker and back in via the microphone. What a great and inexpensive way to help understand how sound waves work!Enhancement request: let me zoom in horizontally while in waveform mode, and display the time scale.

Sound design, the best $.99 cents you’ll ever spend

100% great! I love this application I use it to monitor modulation characteristics on my Ham radio with the external microphone input. The graphics are really good kinda hard to tell your not looking at a dedicated scope, in spectrum mode you can clearly see band pass filter roll off. I would like to be able to vary the time base in scope mode perhaps in another version or update you do have the option of adjusting the vertical gain in scope mode and selecting linear or logarithmic display in spectral mode. Truly a five star development 73 de KF6FOK

I think I am one of the first people to download this app when it first came out years ago!

Very powerful and robust little app! A fascinating, teaching aid for both technical and non-Technical applications! Extremely interesting!!!

It works!Useful tool to have, very modest price.The user interface is real eye candy - in the same vein as the first AAA apps designed for iPhone.Really happy with this. Thanks for creating it. I don’t see an approximate dB level when in waveform mode. That would nice.
