How to apply embedded filters

Previous pageReturn to chapter overviewNext page

Active Sound Recorder allows applying different kinds of IIR (Infinite Impulse Response) and FIR filters (Finite Impulse Response) , like Low-Pass, High-Pass, Band-Pass and Stop-Band, in two situations:


during a recording session by invoking the FilterApply method: in this case the filter is applied directly to the incoming audio data before being encoded and stored into the output audio file or memory buffer. The filter can be disabled at any time through the FilterReset method and its parameters can be modified by invoking the FilterParametersSet method.
after the recording session is completed and finalized by invoking the RecordedSound.FilterApply method


Samples of usage of filters can be found inside the following samples installed with the product's setup package:
