Detailed Description

A audio class that captures system wide audio on Windows.

Member Function Documentation

bool WindowsAudio::checkDeviceParams ( Device * activeDevice )

virtual

Checks the sampling rate and bit depth of the device.

Parameters

device Instance of Device that corresponds to the desired system device

std::vector< Device * > WindowsAudio::getDevices ( DeviceType type )

virtual

Receive the list of available record, playback and/or loopback audio devices connected to the OS and return them as Device instances.

Parameters

type	DeviceType that is combination from the DeviceType enum

Returns: std::vector<Device*> A list of Device instances that carry the necessary device information
