PRE-ORDER

The main function

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.

　

NC-curve for display

On the completion of each measurement interval in 1/1 octave mode, NC criterion curve together with NC value evaluated is displayed.


Text file output

The level data for all frequency bands, All Pass and Frequency weighting value (either A or C) can be output to the text file.
