public class Microphone implements AutoClosable

Microphone

All Implemented Interfaces: AutoClosable

Owned recording from an OS audio input, independent of any AI model. Capture uses mono Float32 PCM at 16000 Hz. No device is opened by importing this class. One consumer reads blocks; stop() is safe from another thread. Queued audio is bounded: an overrun raises IOException rather than losing samples silently. close() discards unread audio and releases the device.

Example

try microphone = Microphone.open(): clip = microphone.read()

Properties

Modifier and Type	Member	Description
public readonly property	capturedFrames `capturedFrames as ULong`	Mono frames accepted from the OS since opening, including unread audio.
public readonly property	channels `channels as Int = 1`	Interleaved channel count.
public readonly property	isRecording `isRecording as Boolean`	Whether the device is still capturing.
public readonly property	level `level as Double`	Latest captured block RMS, even when recognition is busy.
public readonly property	maximumLevel `maximumLevel as Double`	Largest block RMS since opening, retained after stop for diagnosis.
public readonly property	sampleRate `sampleRate as Int = 16000`	Capture frequency in Hz.

Methods

Modifier and Type	Member	Description
public override	close `close() as Void`	Stops, wakes pending reads, discards queued audio and frees ownership.
public static	listDevices `listDevices() as ArrayList<AudioInputDevice>`	Enumerates the current OS audio inputs without opening a recording stream.
public static	open `open(bufferSeconds as Int = 10, device as AudioInputDevice = null) as Microphone`	Starts capture only after explicit application/user consent.
public	read `read() as AudioClip`	Waits for a bounded PCM block; null means stopped and completely drained.
public	stop `stop() as Void`	Stops capture and preserves queued audio for the consumer to drain.
