Description

Note: SignalScope Pro is being succeeded by the new SignalScope X. SignalScope Pro will continue to receive maintenance updates and remain for sale on the App Store for a limited time. Beyond that time, you will be able to continue to use SignalScope Pro as long as you run it on a device with a compatible version of iOS. SignalScope X offers powerful new tools and features. You can download it and try it out for free for 7 days.

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.

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.

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
- Stereo Signal Generator
-- Random and periodic pseudorandom noise
-- White and pink noise
-- Frequency sweeps
-- Tone generator

Pro quality

Sleipnirrr

This is a tool, not a toy. Yeah it's not $0.99, but it's solid and accurate.

Discontinued For More Expensive Subscription Product

Tennavan

This was a great but expensive tool. It was discontinued in January 2018 for a $72/year subscription product (Signal Scope X).

Wonderful App for the Novice

CrackedDish

Not being a Sound Engineer at all, this app is an incredible introduction to the world of audio analysis. With my son having a science project on the effects of temperature on tuning forks, and my current involvement with headset and noise testing at work, this app has almost literally been a lifesaver.
The FFT portion in particular has been the highlight of the experience, especially with the options available for time averaging and tracking peak/harmonic values. I wish the RTA allowed you to choose octave bands lower than 1/3 for increased resolution (or would that make the RTA the same as the FFT?).
The ability to screen capture and save the data in a text file have been lifesavers for the science project. While this app/iPad may never replace "formal test equipment" at work, it is helping me to be aware of what test equipment can do in regards to audio analysis. The only thing I haven't tried out yet is using the vibration analysis of this app, but I am looking forward to it.
I have been able to hook up a USB microphone through the iPad dock port, and it has provided a more flat response throughout the available frequency range.
