Analysis of .wav file (sampling rate: 48kHz , format: 16 bit PCM)
The .wav file data recorded on RSR(Real Sound Recording) card for ordinary Sound Level Meter TYPE 6236/Precision Sound Level Meter TYPE 6238 is acquired to calculate and display Leq, Lmax, LE, and Lx(1-99,min) for all frequency bands, All Pass(Z-weighted value) and Frequency weighting value (either A or C).
Temporal waveform or octave level (dB) in bar graph or in numerical list can be displayed.
