SignalScope 3.6.2
Device: iOS Universal
Category: Utilities
Price: $24.99, Version: 3.6.1 -> 3.6.2 (iTunes)
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.SignalScope 3 supports full and partial upgrades to the additional tools and functionality offered in SignalScope Pro. Upgrades may be purchased via in-app purchase.Available in-app purchase upgrades include:- Full upgrade to the functionality of SignalScope Pro.- Signal Generator tool (not the same as SignalSuite).- - Random and periodic pseudorandom noise (period defined by FFT length)- - White and pink noise weighting- - Lin and log frequency sweeps- - Tone generator- Octave and 1/3-octave Analyzer tool (RTA).- - Whole and 1/3-octave RTA (based on digital Butterworth bandpass filters)Fast, Slow, and Impulse response times- - Flat, A, and C frequency weighting- - Equivalent and time-weighted exponential average levels- - Max, peak, and elapsed time also captured- Level Meter tool.- - Flat, A, and C frequency weighting- - Equivalent and time-weighted exponential average levels- - Max, peak, and elapsed time also captured- Data acquisition (text and MAT file data capture) with downloading to Mac or PC via a standard web browser or iTunes File Sharing. Includes support for additional engineering units (V, A, g, ips), which are assignable to audio input channels.
What's New
Version 3.6.2- Audio sample rate changes are handled more gracefully.Version 3.6.1- The Oscope tool handles drawing short time scales more efficiently, especially with higher sample rates.- Plotting is handled more intelligently by the FFT and Oscope tools when using normal mode triggering with short FFTs or small time scales.- Manual vertical scale adjustments are handled properly with normal mode triggering enabled.Version 3.6- Advanced options for audio device configuration enable user selection of the hardware sample rate. Arbitrary values can be entered for the desired sample rate and the closest supported hardware sample rate will be automatically selected by iOS.- Measurement mode, which disables the high-pass filter on the built-in mic and headset input, can be turned on or off.
