objective-c - 语音开始时自动录音，语音停止时自动播放

Question

谁能为我提供以下帮助:

自动录制语音，并在保持沉默(例如说话汤姆)时播放。谁能帮助我确定谈话汤姆背后的逻辑。当用户开始讲话时，它应该自动录音，而当用户停止讲话时，则应该播放录制的声音。这怎么办？请帮我。

提前致谢

Answer 1

float peakPowerForChannel = pow(10, (0.05 * [soundRecorder peakPowerForChannel:0]));
float averagePowerForChannel = pow(10, (0.05 * [soundRecorder averagePowerForChannel:0]));
lowPassResults = ALPHA * peakPowerForChannel + (1.0 - ALPHA) * lowPassResults;  
averagePassResults = ALPHA * averagePowerForChannel + (1.0 - ALPHA) * averagePassResults;

if (peakPowerForChannel > 0.08f) {
    [soundRecorder recordForDuration:5];
} else {
    NSLog(@"not audible");
}
