Detailed Description

Time-domain audio gain.

Very simple time-domain linear audio amplifier. For lower the volume choose values between 0 and 1. Values over 1 will amplify the audio signal. Gain=1 means no change.

Member Function Documentation

bool CLAM::AudioBufferAmplifier::ConcreteConfigure ( const ProcessingConfig &   )  [inline, protected, virtual]

Configuration method interface.

The Processing base class forces all the concrete classes derived from it to implement this method, which must actually perform the specific configuration tasks.

Note that the user can not call this method directly. He will use Configure instead. The argument is expected to be an object of the necesary concrete configuration class.

Parameters:
Reference to the configuration object.
Returns:
false if the object is not yet fully configured. (For example, if some important configuration attribute such as number of ports was set to zero in the config object)

true if the processing object is left in a consistent state, and can be executed.

Exceptions:
This method must throw a bad_cast exception if the argument is not an object of the expected configuration class.

bool CLAM::AudioBufferAmplifier::Do (  )  [inline, virtual]

Supervised mode execution method (using ports).

Returns:
A boolean telling whether it has been output

Implements CLAM::Processing.

const ProcessingConfig& CLAM::AudioBufferAmplifier::GetConfig (  )  const [inline, protected, virtual]

Configuration getter.

Gets the configuration parameters used to create the object.

Returns:
Const reference to the configuration object. The usual way to perform a configuration change in the processing object is to take a copy of this reference, to change it and to send it with the Configure method. If not overriden, it returns a NullProcessingConfig.

virtual bool CLAM::AudioBufferAmplifier::SupportsVariableAudioSize (  )  const [inline, virtual]

This method reports whether the processing supports dynamic buffer-size host.
