Start Recording with device.

If you pass a null or empty string for the device name then the default microphone will be used. You can get a list of available microphone devices from the devices property. You can find the range of sample rates supported by a microphone using the GetDeviceCaps property.

Note that if you want to use the Microphone class in the web player, you need to get the user's permission to do so. Call Application.RequestUserAuthorization before calling any Microphone methods.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Start() { AudioSource aud = GetComponent<AudioSource>(); aud.clip = Microphone.Start("Built-in Microphone", true, 10, 44100); aud.Play(); } }

Note that web player is not supported from 5.4.0 onwards.
