A room can be defined by different acoustical parameters (decay curve, reverberation time, early decay time, clarity..). In order to measure these parameters, different techniques can be used like periodic pulse testing, time-delay spectrometry (TDS) and maximum-length sequences (MLS).
This project deals with a system measuring room acoustical parameters using the Maximum-Length Sequence (MLS) method. This system is based on both a DSP and a PC where the DSP generates the MLS and extracts the room impulse response. The PC calculates the parameters and displays them in a graphical user interface (GUI) which also controls the measurement.
