SignalScope Pro at Mac App Store analyse

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 devices 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
