How to read the data from AudioClip using PCMReaderCallback when the former is created by Microphone.Start in...
How can I change the code below to use the PCMReaderCallback to read data from the audio clip created by Microphone.Start?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class NewBehaviourScript : MonoBehaviour
{
private string m_deviceName = null;
private AudioClip m_audioClip;
void Start()
{
bool loop = true;
int lengthSec = 10;
int frequency = 44100;
m_audioClip = Microphone.Start(m_deviceName, loop, lengthSec, frequency);
}
void Stop()
{
Microphone.End(m_deviceName);
m_audioClip = null;
}
}

You cannot use the Microphone API with PCMReaderCallback. This is because PCMReaderCallback is registered by passing the PCMReaderCallback function to the AudioClip.Create function which returns a new AudioClip. Unity's Microphone.Start function returns AudioClip but it doesn't take PCMReaderCallback as argument.
If this is not a Microphone but a simple audio clip then you could with the example below:
public int lengthSamples = 400;
public int channels = 2;
public int frequency = 16000;
AudioSource adSource;
void Start()
{
adSource = GetComponent<AudioSource>();
AudioClip clip = AudioClip.Create("clip", lengthSamples, channels, frequency, true, OnAudioRead);
adSource.clip = clip;
adSource.Play();
}
//PCMReaderCallback callback
void OnAudioRead(float data)
{
}
If you just want to read the audio data from the Mic, you can still use OnAudioFilterRead or the AudioSource.clip.GetData function. Below is an example for OnAudioFilterRead.
string m_deviceName = null;
AudioSource adSource;
void Start()
{
adSource = GetComponent<AudioSource>();
bool loop = true;
int lengthSec = 10;
int frequency = 44100;
AudioClip clip = Microphone.Start(m_deviceName, loop, lengthSec, frequency);
adSource.clip = clip;
while (!(Microphone.GetPosition(null) > 0)) { }
adSource.Play();
}
void OnAudioFilterRead(float data, int channels)
{
}

Thanks for sharing. Two more questions. Whywhile (!(Microphone.GetPosition(null) > 0)) { }? How to avoid the microphone input to be played back?

Withoutwhile (!(Microphone.GetPosition(null) > 0))there can be a bug in your code. For example, trying to access the data from mic may return 0. This is a problem I see on this site all the time so you have to wait until the pos is >1. You may not run into it but many that will use your app will. Also that can cause audioclip to not even play at-all. For your second question, see my other answer.
