SignalScope
By Faber Acoustical, LLC
Open iTunes to buy and download apps.
Description
SignalScope turns your iOS device into a powerful real-time spectrum analyzer and oscilloscope. Easily measure audible frequencies in SignalScope’s FFT analyzer. “Touch” your data with highly interactive, multi-touch enabled analyzer displays. See http://youtube.com/faberast for video demos.
Input signals can be acquired from the built-in accelerometer, or from the current audio input path (iOS automatically selects the audio input path according to which external audio devices, if any, are connected to your device).
NOTE: The built-in and headset microphones of all recent iOS device models pass through a high-pass filter which significantly attenuates low-frequency signal content.
For iPhone/iPod touch audio I/O compatibility and frequency response measurements, visit http://blog.FaberAcoustical.com.
FEATURES
- Analyze signals coming from the iPhone's built-in or headset microphone, or from the built-in accelerometer.
- View real time analyzer displays on an external screen (supported on iPad only).
- Audio input is sampled at 48 kHz or 44.1 kHz, built-in accelerometer data is sampled at 100 Hz.
- Zoom in or out on spectrum and waveform displays with two-finger expand/pinch gestures, even while the analyzer is running.
- Pan vertically or horizontally in zoomed displays with two-finger scrolling.
- Pinpoint individual sample values or frequencies with a cursor.
- Save high-resolution spectrum or waveform display images as PDF files or as JPEG images in the iPhone's Camera Roll photo album.

Customer Reviews
Not cheap, but a FANTASTIC spectrum analyzer
I'll keep this short: this app certainly isn't cheap. But it works incredibly. No lag, excellent interface, very powerful. This (and the other apps by Faber Acoustical) are basically SMAART tools for iOS, it's incredible what they can do. I am a sound engineer, and ringing out monitors takes about 1-2 minutes with this app...no frequency guessing required. Great to have in your pocket at all times. Couple this app with a nice digital board with some parametric EQs, and you are set. Beautiful piece of software that I use all the time, and it makes coworkers and friends jealous! The Retina support for the iPhone AND iPad is incredible. Do your research and you'll see that this app is worth the price.
