Data Operations
About data filtering
- I want to cut frequency components above 15 kHz.
- I want to apply filter processing while listening to the sound.
- I recorded the acceleration waveforms with different software and converted them into displacement, but I want to clean up the waveforms due to low-frequency noise.
File Import/Export
- What types of files can be imported?
- What do you set for importing a CSV file?
- What kinds of file formats can be exported?
- How can I extract only the segment with data and export it in WAVE file format?
- How can I extract only the interval with data and export it in CSV file format?
install
- If the license key is not recognized.
- Things to be careful about during installation.
- What is the OS-2000 series icon that appears in the status bar when the computer starts up?
- I want to know which applications are registered with the license key. (Regarding license verification)
- About the installation of .NET Framework 3.5 on Windows 10
Calibration
- Method to directly input the sensitivity value of the sensor.
- When recording with the DS-0250, I accidentally recorded with the unit name set to 'V'. The physical quantity (EU value) is set to the correct value. How can I change the unit in the OS-2000 series?
- Which option is the "Signal calibration" feature?
- What types of calibration methods are there?
- Method of calibration using sound pressure calibration signals.
About Sampling
- I want to display data recorded in the 20 kHz range using an FFT analyzer at the 4 kHz range.
- What is the sample frequency of time waveform data that can be analyzed using 1/N octave analysis?
Sound playback
About waveform analysis
- I want to see the changes in sound pressure level over time.
- Can multiple waveforms be drawn on the time trend screen?
- I want to analyze a singular phenomenon within a continuous sound. Is it possible to perform continuous analysis using FFT?
- I want to see the passage of time in 1/3 octave.
- When exporting the color map display values of the wavelet transform to a CSV file, an error message appears as shown below if the output CSV file size exceeds 2GB.
- During sound quality evaluation, when executing the analysis, the message "Cannot analyze data above 130dB. Processing will stop" is displayed, and the analysis cannot proceed.
- I want to display the result of subtracting two power spectra using basic frequency analysis (FFT analysis).
- About the PSD calculation formula.
