Applying a Frequency Weighting to a Signal
Sound: Analysis and Specification allows you to apply a frequency weighting to temporal signals. There are different perception-related filters to weight a signal: the A/B/C frequency-weighting filters.
Note: By default, all temporal signals are displayed with SPL filter (no filter).
Sound: Analysis and Specification also allows you to display spectral and time frequency signals with a frequency weighting.
Sound: Analysis and Specification uses weighting filters that are compliant with the filter shapes specified in the standard IEC 61672 for A, B and C weightings.
To Apply a Frequency Weighting to a Signal:
- Open a temporal signal.
- Click the temporal signal or time-frequency representation.
- Click .
- If several signals are opened in the same window, select the signal to be filtered in the Signal drop-down button.
- Check Add to a new block.
- Enter a name for the new block.
- Click OK.
- Click Play to listen to the weighted signal.
