音量检测
检测当前麦克风的输入音量
using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.UI;public class NewBehaviourScript2 : MonoBehaviour{ private static int VOLUME_DATA_LENGTH = 128; //录制的声音长度 public float volume; //音量 public Text text; public Slider slider; private AudioClip mMicrophoneRecode; //录制的音频 private string mDeviceName; //设备名称 public int xishu=1000; private const int frequency = 44100; //码率 private const int lengthSec = 999; //录制时长 // Use this for initialization void Start () { //获取设备名称 mDeviceName = Microphone.devices[0]; //录制一段音频 mMicrophoneRecode = Microphone.Start(mDeviceName, true, lengthSec, frequency); } // Update is called once per frame void Update () { volume = GetMaxVolume(); volume*=xishu; slider.value=Mathf.Lerp(slider.value,volume/200,0.1f); text.text=volume.ToString(); } /// /// 获取最大的音量 /// /// /// /// 音量大小 /// private float GetMaxVolume() { float maxVolume = 0f; //用于储存一段时间内的音频信息 float[] volumeData = new float[VOLUME_DATA_LENGTH]; int offset; //获取录制的音频的开头位置 offset = Microphone.GetPosition(mDeviceName) - VOLUME_DATA_LENGTH + 1; if(offset < 0) { return 0f; } //获取数据 mMicrophoneRecode.GetData(volumeData, offset); //解析数据 for(int i = 0;i < VOLUME_DATA_LENGTH; i++) { float tempVolume = volumeData[i]; if(tempVolume > maxVolume) { maxVolume = tempVolume; } } return maxVolume; }}
关键字识别
此处利用win10自带的识别
记得引入
