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).

For iOS device audio I/O compatibility and frequency response measurements, visit http://blog.FaberAcoustical.com.

FEATURES
- Analyze signals coming from the iOS device’s current audio input source, 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

Very useful

I do recording and sound reinforcement at many different venues. This app works great, I will use this with my white noise generator to set room EQ. Don't need to buy extra devices, just use my I-pad. Not dirt cheap like some other apps but you get what you pay for.
