Details

This app helps to set up a listening room. 
Connect your Android device to your sound system and start the measurement.
Result are curves for frequency response, phase, impulse response.
Likewise waterfall diagrams and sound pressure maps can be generated.

Features

 - Measurement via logsweep 
 - Serial function for fast measurement at many microphone positions
 - Automatic determination of the microphone position based on the sound propagation times  
 - Automatic generation of file names - fast saving of single measurements by OK-click  
 - Frequency response: sum frequency response and windowed  
 - Fade-in of calculated reflections (comb filter) for comparison with the measurement data 
 - Phase: raw data, rolled up and group delay
 - Impulse response - linear: raw data, smoothed data, step response, energy-time curve   
 - Impulse response - logarithmic: raw data, smoothed data, maximum values, Energy-Time-Curve, Schroeder Curve  
 - Impulse response filter for windowed frequency responses or waterfall plots    
 - Display of tangents of the Schroeder curve for EDT, T15, T20, T30 or freely definable rules
 - Display of frequency response and impulse response customizable: zoom, curves can be shifted against each other, different orders...  
 - T60 as a function of frequency and comparison with DIN 18041, IEC 60268 13, EBU Tech 3276 (2nd)
 - Waterfall display (time evolution of frequency response) via wavelet or FFT analysis
 - Spectrogram representation 
 - Frequency-dependent sound pressure map     
 - Calibration possibilities for the built-in microphone by comparison measurements, if a measurement microphone is available.
 - Use of measurement microphones (import of calibration curve). 
 - Export of results: in HTML format 
 - Export of measurement data: Impulse response accessible as .wav file and measured values in CSV and .FRD format. 
 - Export of frequency response and phase in .FRD format (allows import and further processing with many audio measurement programs) 
 - English and German
