If there are the same tasks every time you add a file to a Unity project, they should be automated. The task can be automated by hooking an event on import.For example,using UnityEditor;

By using OnAudioFilterRead method of MonoBehaviour class, you can apply a custom filter to the playing audio or generate a waveform. If you attach a component that implements OnAudioFilterRead to a GameObject that has an AudioSource, you can filter the sound that comes from that AudioSource.For example, the following code halves the audio signal level:void OnAudioFilterRead(float[] data, int channels)

When dealing with AudioClip in Unity, one thing you don't want to do is manage the AudioSource every time you play. Therefore, we recommend using the following AudioManager class. Even if you want to perform more complex controls such as stopping the sound once played, changing the volume, etc., you should customize this AudioManager class.using UnityEngine;public class AudioManager : MonoBehaviour
