C++ (Cpp) fa_audio_output_channels Examples

Example #1

File: list_audio.c Project: EQ4/faudio

/*
    This program prints the currently connected audio devices.

    The output consists of device declarations separated by blank lines.

    An example device declaration:

        Name:           Built-in Microphone
        Host:           Core Audio
        Input:          2
        Output:         0
