説明

Add this function to a subclass to get a notification just before an audio clip is being imported.

これによりインポート設定をコードにより制御できます。

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

public class MyAudioPostprocessor : AssetPostprocessor { void OnPreprocessAudio() { if (assetPath.Contains("mono")) { AudioImporter audioImporter = (AudioImporter)assetImporter; audioImporter.forceToMono = true; } } }
