Detailed Description
Class MicrophoneAudio provides the means to read raw audio samples from a microphone.
Definition at line 25 of file microphoneAudio.h.
Member Function Documentation
◆ find_all_microphones()
|
static |
Scans the hardware for microphones, and pushes them onto the global list of all microphones.
There are several implementations of MicrophoneAudio, including one based on DirectShow, one based on Linux ALSA, and so forth. These implementations are contained in one C++ file each, and they export nothing at all except a single "find_all" function. Otherwise, they can only be accessed through the virtual methods of the MicrophoneAudio objects they create.

Member Data Documentation
◆ get_channels
|
inline |
Returns the number of channels.
Definition at line 38 of file microphoneAudio.h.
◆ get_num_options
| int MicrophoneAudio::get_num_options |
Returns the number of microphone options.
An "option" consists of a device plus a set of configuration parameters. For example, "Soundblaster Audigy Line in at 44,100 samples/sec" would be an option.
Definition at line 32 of file microphoneAudio.h.
◆ get_rate
|
inline |
Returns the sample rate.
Definition at line 39 of file microphoneAudio.h.
