Question

我是团结开发的初学者。我试图在团结中做一个Android应用程序，用户可以录制音频按下按钮，当他发布时，录制的音频必须在循环播放。到目前为止，我学会了如何从麦克风录制音频，以及播放音频的播放功能。

我无法做的事情

1.Cannot使用按钮按住和释放功能 2.无法在项目目录中找到保存的录音。

我已按照this thread录制和播放音频我已经实现了相同的代码块。它现在正在做的是录制我的声音并在我按下按钮时录制它。

对此有任何帮助将不胜感激。

提前致谢。

这是我尝试过的代码实现：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class audiorecorder : MonoBehaviour
{
    AudioClip reco;
    // Use this for initialization
    public void onClick() {
    AudioSource aud;
        aud = GetComponent<AudioSource>();
        foreach(string device in Microphone.devices)
        {
            Debug.Log(device);
        }
    reco = Microphone.Start("Built-in Microphone", true, 10, 44100);
    aud.clip = reco;

    aud.Play();
}

}

Answer 1

如果您想使用鼠标上下移动，则必须使用IPointDownHandler命名空间中的IPointerUpHandler和UnityEngine.EventSystems接口。要使用系统默认麦克风，您应该为Microphone.Start函数指定设备名称的空字符串

下面的脚本应该有效，但我没有机会测试它，因为我现在没有麦克风。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;

//Use the PointerDown and PointerUP interfaces to detect a mouse down and up on a ui element
public class AudioRecorder : MonoBehaviour, IPointerDownHandler, IPointerUpHandler{
    AudioClip recording;
    //Keep this one as a global variable (outside the functions) too and use GetComponent during start to save resources
    AudioSource audioSource;
    private float startRecordingTime;

    //Get the audiosource here to save resources
    private void Start()
    {
        audioSource = GetComponent<AudioSource>();
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        //End the recording when the mouse comes back up, then play it
        Microphone.End("");

        //Trim the audioclip by the length of the recording
        AudioClip recordingNew = AudioClip.Create(recording.name, (int)((Time.time - startRecordingTime) * recording.frequency), recording.channels, recording.frequency, false);
        float[] data = new float[(int)((Time.time - startRecordingTime) * recording.frequency)];
        recording.GetData(data, 0);
        recordingNew.SetData(data, 0);
        this.recording = recordingNew;

        //Play recording
        audioSource.clip = recording;
        audioSource.Play();

    }

    public void OnPointerDown(PointerEventData eventData)
    {
        //Get the max frequency of a microphone, if it's less than 44100 record at the max frequency, else record at 44100
        int minFreq;
        int maxFreq;
        int freq = 44100;
        Microphone.GetDeviceCaps("", out minFreq, out maxFreq);
        if (maxFreq < 44100)
            freq = maxFreq;

        //Start the recording, the length of 300 gives it a cap of 5 minutes
        recording = Microphone.Start("", false, 300, 44100);
        startRecordingTime = Time.time;
    }

}

Answer 2

SavWav：（您需要将其作为脚本添加到您的项目中）code

using System.Threading;（用于睡眠功能）

int frequency = 44100; //Wav format frequency
int numberOfSecondsToRecord = 10;

var rec = Microphone.Start("", false, numberOfSecondsToRecord, frequency);
Thread.Sleep(numberOfSecondsToRecord * 1000); //To miliseconds
if(rec != null)
{
  SavWav.Save(Application.persistentDataPath + "/test.wav", rec);
}

上述代码的主要作用是启动麦克风，如果成功完成，则返回正在录制的现场音频的音频剪辑，您必须等到录制完成后才保存。
