https://stackoverflow.com/questions/19353/detecting-audio-silence-in-wav-files-using-c-sharp
So, I wrote an extension method for the AudioFileReaderclass which returns the silence duration at the start/end of the file, or starting from a specific position. Here: static class AudioFileReaderExt{ public enum SilenceLocation { Start, End } private static bool IsSilence(float amplitude, sbyte threshold) { double dB = 20 * Math.Log10(Math.Abs(amplitude)); return dB < …

Detecting audio silence in WAV files using C#. Audio analysis is a difficult thing requiring a lot of complex math (think Fourier Transforms). The question you have to ask is "what is silence". If the audio that you are trying to edit is captured from an analog source, the chances are that there isn't any silence... they will only be areas of ...

-55.7021600863786 in dB As we can see, the db level hovers around -55 when there is no input sound, only silence. if I record saying "Hello" in mic in a normal tone, the db value will goto -20 or so. I read somewhere that average human talk is around 20dB and -3dB to -6dB is the ZERO value range for mic.

Internally, it Grabs a buffer of 8-bit samples from the soundcard. 8-bit means each sample value is 0-256, with 127 being silence. Loops through the buffer, and if there is a value greater than the threshold, raise an event Get the Detector library (+ source + sample C# application) Feel free to use it in your own projects.
