Android audio capture silence detection

Question

I found this android code to record the user sound when he/she starts to speak and stop recording when he/she stops. But the problem is that the recording stops very quickly

Answer 1

Code from this post is working. But has some issue. The fact is that the record is interrupting too severely abruptly. And sound is playing by stuttering. For solving I created conter silenceDegree.

See my Kotlin code:

var threshold: Short = 5000
val SILENCE_DEGREE = 15

//buffer size - need be fixed, established value for IOS compatibility
val buffer = ShortArray(MIN_SIZE)
var silenceDegree = 0

while (record) {
    val bytesRead = audioRecord?.read(buffer, 0, MIN_SIZE)
    if (bytesRead != null) {
        if (bytesRead > 0) {
            val foundPeak = searchThreshold(buffer, threshold)

            if (foundPeak == -1) {
                if (silenceDegree <= SILENCE_DEGREE) {
                    silenceDegree++
                }

            } else {
                silenceDegree = 0
            }

            //stoping to send, only when counter became equals SILENCE_DEGREE 
            if (silenceDegree < SILENCE_DEGREE) {
                //SEND USEFUL DATA  
                handler.sendDataOnRecord(INSTANCE.shorts2Bytes(buffer))
            }

        } else {
            if (bytesRead == AudioRecord.ERROR_INVALID_OPERATION) {
                // This can happen if there is already an active
                // AudioRecord (e.g. in another tab).
                record = false;
            }
        }
    }
}
