Input Form
Seismic wave file
Input file format:
Sampling frequency:  Hz
Integrate seismic wave:
(Integrate seismic wave before transformation: Acc. -> Vel., Vel. -> Dis.)
Frequency correspondence: 1 Hz of seismic wave = Hz of sound wave(*3)
Tone:
*1: Example of text format is here
*2: K-NET is the strong ground motion observation network by National Research Institute for Earth Science and Disaster Prevention.
*3: Frequency change of sound wave is syncronized with that of seismic wave.1 decade of frequency change of seismic wave corresponds to 1 octave of that of sound wave.
