This function converts a tone into its corresponding string value.

Returns the average power at a given frequency

Returns the average power at a given frequency

Returns the frequency at the given FFT index

Returns the "x" (horizontal) position within the control's graphic area given the FFT index

Returns the frequency response at a given FFT index

Returns the FFT index for a given frequency

This subroutine must be called in order to "register" the control and prevent it from displaying the "DEMO" message.

Converts an array of bytes into an array of integers with values ranging from -32768 to 32767 This function is used, internally by the control, but you may also use it when handling the PeakValues event.

Pauses the playback

This is an advanced feature that allows you to use your own buffer provider. When a custom provider is set, DXVUMeterNETGDI will query the provider to obtain the buffer data, instead of using its internal audio monitoring routines. This can be useful if your application is gathering the buffer data from a non standard source or if, for example, you want to plot some data that is not directly provided by a sound card.

Starts monitoring and rendering the monitored audio

Starts playing the file passed as a parameter

Starts recording so the monitored audio will be saved into the file passed as a parameter NOTE: DXVUMeterNETGDI uses the LAME encoder to encode the PCM audio into MP3 format. Please refer to http://www.mp3dev.org/ for more information about the LAME encoder.
