Description

SignalScope Pro for iOS devices is a real-time signal analysis toolset, suitable for use in areas such as acoustics, audio, electronics, and vibration. SignalScope Pro includes tools for dynamic signal analysis, as well as a signal generator for producing test signals. See http://youtube.com/faberast for video demos.

For more information regarding compatible audio hardware, visit http://blog.FaberAcoustical.com.

Features:
- Analyze signals coming from the iOS device’s current audio input device or from the built-in accelerometer.
- Assign input channel units and sensitivities for individual USB Audio devices. Direct support is included for the Digiducer 333D01 accelerometer and miniDSP UMIK-1 measurement microphone.
- Manually switch between available audio input and output sources.
- Load microphone frequency response data (FRD) and apply frequency response correction (FRC) to FFT spectrum measurements.
- Audio input is typically sampled at 48 kHz or 44.1 kHz (higher and lower sample rates are possible, even up to 192 kHz, with hardware that supports it). Built-in accelerometer data is sampled at roughly 100 Hz.
- Assign engineering units to your input signals and calibrate external transducers for accurate measurements.
- Save acquired time or frequency data to CSV, tab-delimited ASCII text, or MAT files.
- Retrieve your data files from your device via iTunes File Sharing, or through a web browser on your Mac or PC.
- Save high-resolution analyzer display images to PDF files or to the iOS device's built-in photo album.
- Pinpoint individual sample values or frequencies with a cursor.
- Zoom in or out on FFT 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.

Tools:
- FFT Analyzer
-- Frequency resolutions between 0.5 Hz and 50 Hz may be specified for audio input (between 0.1 Hz and 10 Hz for the built-in accelerometer)
-- Input data can be windowed with one of 7 different data window types
-- Lin, log, and dB magnitude scales
-- Lin and log frequency scales
-- Auto, normal, and single-shot triggering
-- Trigger slope and threshold options
- Real-time Spectrogram Analyzer (available via in-app purchase in 2D and 3D versions)
-- Frequency resolutions between 1 and 50 Hz may be specified for audio input (between 1 Hz and 10 Hz for the built-in accelerometer)
-- Input data can be windowed with one of 7 different data window types
-- Lin, log, and dB magnitude scales
-- Lin and log frequency scales
-- Fractional-octave band frequency smoothing in 1/6, 1/12, and 1/24-octave bands.
-- Cursor peak track can track peaks in time, frequency, or both.
-- Color scale bar graph enables manual adjustment of magnitude scale and offset. The color scale can also be hidden.
-- Data may be exported to CVS, MAT, or TXT files for post processing or plotting. Optionally, include GPS location information with exported data.
-- Optionally save a high-resolution PDF file of the spectrogram plot, or save an image to your Photos library.
- Octave-band Analyzer
-- 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
-- Equivalent and time-weighted exponential average levels
-- Flat, A, and C frequency weighting
-- Max, peak, and elapsed time also captured
- Oscilloscope
-- Time scales from 0.1 to 1.0 second per division
-- Auto, normal, and single-shot triggering
-- Trigger slope and threshold options
- Stereo Signal Generator
-- Random and periodic pseudorandom noise (period defined by FFT length)
-- White and pink noise weighting
-- Lin and log frequency sweeps
-- Tone generator

What's New in Version 6.0

- A new real-time Spectrogram analyzer tool is offered within SignalScope Pro via in-app purchase. The Spectrogram is available in 2D and 3D versions. The 3D Spectrogram includes all the functionality of the 2D version and adds powerful hardware-accelerated 3D plotting capabilities including a live 3D surface plot.
- The Spectrogram Tool offers FFT-based spectral analysis plotted over a time interval ranging from 2 to 20 seconds and frequency resolution ranging from 1 to 50 Hz.
- GPS coordinates, altitude, and accuracy may now optionally be saved with FFT, Spectrogram, or Oscope data when exporting to a data file.
- Downloaded frequency response data for connected microphones will automatically be saved in a file in the Frequency_Response_Data folder to make it easier to access at a later time.
- Smarter selection of the maximum frequency when FFT data smoothing is enabled.
- Fixed an issue with Full Autoscale in the FFT analyzer.
- Other minor cosmetic improvements and bug fixes.
