[iPhone God App] It was found using the SignalScope Pro actually

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 4 tools for dynamic signal analysis, as well as a signal generator for producing test signals. See http://youtube.com/faberast for video demos.

SignalScope Pro also turns your iOS device into a platform for data acquisition, storing acquired data in CSV or TXT files, MAT-files, or PDF or JPEG images for later retrieval from your device.

Input signals can be acquired from the current audio input path or from the built-in accelerometer. Different engineering units, including Volts, Amps, pascals, m/s^2, m/s, g’s, and ips (inches per second) can be assigned to input channels of the dock connector audio input or the headset input. Sensitivity calibration can also be performed for any audio input device or input channel.

SignalScope Pro enables you to “touch” your data with highly interactive, multi-touch enabled analyzer displays.

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 spectrum and waveform displays with two-finger expand/pinch gestures, even while the analyzer is running (FFT analyzer and oscilloscope).
- Pan vertically or horizontally in zoomed displays with two-finger scrolling (FFT analyzer and oscilloscope).
