![]() ![]() Assume the use of tsp8.wav having eight TSP signals. Play multiple TSP signals because their addition reduces background noise and reverberation. ![]() Impulse responses are measured in two steps: (1) playing and recording the TSP signal, and (2) calculating impulse responses from TSP signals. Wavesurfer /usr/bin/harktool3_utils/16384.little_endian.tspįigure 5.1: Configuration of wavesurfer needed to read raw files Directions To read the file, use wavesurfer (to install on Ubuntu, use sudo apt-get install wavesurfer) Then, open the file with wavesurfer, This is a raw file, with32 bit floating amplitude data installed in series. Similarly, 16384.little_endian.tsp is also installed to the same path. However, if the environment is noisy, e.g., an air conditioner is running, we recommend to use 16-times TSPs to suppress the effect of the noise. If the environment is quiet, you can use 8-times TSPs which is short. You can decide the number of TSPs depending on the environment of the measurement. Note that NO spaces should be inserted between TSPs. Since this file includes a single TSP signal, it is necessary to cut and paste to make multiple TSPs (e.g., 8 or 16 times) using waveform editing software, such as matlab, or python. Upon installing harktool , a wave file of a single TSP signal is installed in /usr/bin/harktool3_utils the file name is 16384.little_endian.wav. You need a loudspeaker, a microphone array, an audio device that can simultaneously play and record a sound, and a signal including multiple TSPs. To measure impulse responses for sound source localization and sound source separation.
