实时生成音频以写入“SourceDataLine”`

我想知道是否有可能将动态生成的音频不断输出到 DataLine 例如,声音会根据用户输入等某种状态而变化。我正处于可以无限期地写入行的状态,但我只是不断地不间断地写入,而不是根据需要只保留一小段额外的音频缓冲区。除了打电话,有没有别的办法 Thread.sleep 在循环中缓冲的持续时间?

var phase = 0F
fun generateBuffer(n: Int, buffer: FloatBuffer) {
    // Some potentially state-sensitive audio generation procedure. Generating a pure sine as an example.
    repeat(n) {buffer.put(sin((phase + it * 2 * PI * 440 / 44100F).toFloat()))}
    phase += (n * 2 * PI * 440 / 44100F).toFloat()
}

fun main() {
    val dataLineInfo = DataLine.Info(
        SourceDataLine::class.java,
        format)
    val dataLine = AudioSystem.getLine(dataLineInfo) as SourceDataLine
    dataLine.open()

    val intBuffer = byteBuffer.asIntBuffer()
    val floatBuffer = FloatBuffer.allocate(BUFFER_SIZE)
    dataLine.start()

    // This just generates and writes data nonstop. Can I generate chunks of audio on-demand as they are exhausted?
    while (true) {
        floatBuffer.rewind()
        generateBuffer(BUFFER_SIZE, floatBuffer)
        floatBuffer.rewind()
        intBuffer.rewind()
        repeat(BUFFER_SIZE) { intBuffer.put((floatBuffer.get() * 32767).toInt()) }
        dataLine.write(byteBuffer.array(), 0, 2 * 2 * BUFFER_SIZE)
    }
