SignalScope Pro6.4.3 - App Store

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.

- 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

Requires iOS 7.0 or later. Compatible with iPhone, iPad, and iPod touch.
