AudioInput

Gives PCM input access (such as a microphone).

struct AudioInput {

version(ALSA)

snd_pcm_t* handle;

version(!ALSA && WinMM)

HWAVEIN handle;

version(!ALSA && WinMM)

HANDLE event;

int channels;

int SampleRate;

this(int card, int SampleRate, int channels);

this(string device, int SampleRate, int channels);

short[] read(short[] buffer);

void delegate(short[]) receiveData;

void record();

}

Constructors

this this(int card, int SampleRate, int channels): Always pass card == 0.
this this(string device, int SampleRate, int channels): device is a device name. On Linux, it is the ALSA string. On Windows, it is currently ignored, so you should pass "default" or null so when it does get implemented your code won't break.

Destructor

Members

Functions

read short[] read(short[] buffer): Data is delivered as interleaved stereo, LE 16 bit, 44.1 kHz Each item in the array thus alternates between left and right channel and it takes a total of 88,200 items to make one second of sound.
record void record(): First, set receiveData, then call this.
stop void stop()

Variables

receiveData void delegate(short[]) receiveData;: passes a buffer of data to fill
