SignalScope turns your iOS device into a powerful real-time spectrum analyzer and oscilloscope. Easily measure audible frequencies in SignalScope s FFT analyzer. 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 source, 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 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. - 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 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: - 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 - Real-time Spectrogram Analyzer (available 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 (Data Acquisition Upgrade required). -- Optionally save a high-resolution PDF file of the spectrogram plot, or save an image to your Photos library. - Data acquisition (CSV, TXT 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, m/s^2, m/s, g, ips), which are assignable to audio input channels.
Requires iOS 7.0 or later. Compatible with iPhone, iPad, and iPod touch.
