The current paper presents a software application that conducts electroacoustic measurements using a digital approach to Time Delay Spectrometry. Development was focused on simplified hardware requirements such as a personal desktop or laptop computer. A friendly and flexible user interface has been designed. Linear and logarithmic sweep test signals are generated and reproduced. System under test (e.g. room) response is recorded and stored in the hard disk. Energy Time Curve (ETC) and Frequency domain analysis procedures are guided efficiently. Reverberation time in the case of a room is estimated very fast. All task data may be restored later for further analysis. Finally, the results of comparison measurements using our application to measurements using a widely accepted TDS analyzer are presented
