Car Audio Setup can be seen as an acoustic multimeter for real-time measurements: In the car, neither the mounting location of the loudspeakers nor the listening positions can be changed. The focus of the measurements is therefore on optimizing the frequency response. The app provides the necessary tools with function generator, real-time analyzer and spectrogram. In addition, an oscilloscope helps in troubleshooting: Before the first measurement, experience has shown that it should be ensured that speakers and crossovers have been connected and adjusted correctly. In addition to real-time measurements, frequency response and impulse response can be measured via logsweep for more precise analyses.


Real-time measurements

- Two views, freely configurable with oscilloscope, function generator, real-time analyzer and spectrogram
- Mono and stereo microphones supported
- Use of measurement microphones (import of calibration curve)
- English and German

Oscilloscope
- Trigger and rolling display
- 4 channels: Microphone (L, R), function generator (L, R)
- Switchable automatic gain control for microphone channel (AGC)

Function generator
- Two separately configurable generators, output mixable
- Sine and white noise
- Burst
- Polarity, balance and delay of stereo channels adjustable

Realtime Analyzer and Spectrogram
- FFT window, length, average and overlap of consecutive FFTs
- Zoom with 2-finger gestures
- Pause button and snapshots of multiple curves for analysis of short sound events


Measurement by logsweep

- Series function for fast measurement at many microphone positions
- Automatic determination of microphone position based on sound travel times
- Fade-in of calculated reflections (comb filter) for comparison with measurement data
- Impulse response - linear: raw data, smoothed data, step response, energy-time curve
- Impulse response - logarithmic: raw data, smoothed data, maximum values, energy-time curve
- Display of frequency response and impulse response customizable: zoom, curves can be shifted against each other, different orders...
- Export of results: in HTML format
- Export of measurement data: Impulse response as .wav file and measured values in CSV and .FRD format accessible
- Export of frequency response and phase in .FRD format (allows import and further processing with many audio measurement programs)


All measurements
- Use of measurement microphones (import of calibration curve)
- Calibration possibilities for the built-in microphone by comparison measurements, if a measurement microphone is available.
- English and German
