Unity3D PC平台本身是支持直接用www读取本地ogg,wav的，但是并不能读取byte[]，字节数组格式，这对用习惯了bass,fmod的人来说有点不方便。

搜了一圈发现了一个C#的音频库叫NAudio，开源并且免费。

简单粗暴的搞一份二进制release，然后nuget一下ogg扩展

Install-Package NAudio.Vorbis　　

使用方面参考了下面3个地址

简单来说新建一个NAudioPlayer.cs文件，内容如下

using UnityEngine;using System.IO;using System;using NAudio;using NAudio.Wave;public static class NAudioPlayer{    static NVorbis.VorbisReader vorbis;    public static AudioClip FromOggData(byte[] data)    {        // Load the data into a stream        MemoryStream oggstream = new MemoryStream(data);        vorbis = new NVorbis.VorbisReader(oggstream, false);        int samplecount = (int)(vorbis.SampleRate * vorbis.TotalTime.TotalSeconds);        //  AudioClip audioClip = AudioClip.Create("clip", samplecount, vorbis.Channels, vorbis.SampleRate, false, true, OnAudioRead, OnAudioSetPosition);        AudioClip audioClip = AudioClip.Create("ogg clip", samplecount, vorbis.Channels, vorbis.SampleRate, false, OnAudioRead);        // Return the clip        return audioClip;    }    static void OnAudioRead(float[] data)    {        var f = new float[data.Length];        vorbis.ReadSamples(f, 0, data.Length);        for (int i = 0; i < data.Length; i++)        {            data[i] = f[i];        }    }    static void OnAudioSetPosition(int newPosition)    {        vorbis.DecodedTime = new TimeSpan(newPosition); //Only used to rewind the stream, we won't be seeking    }    public static AudioClip FromWavData(byte[] data)    {        WAV wav = new WAV(data);        AudioClip audioClip = AudioClip.Create("wavClip", wav.SampleCount, 1, wav.Frequency, false);        audioClip.SetData(wav.LeftChannel, 0);        return audioClip;    }    public static AudioClip FromMp3Data(byte[] data)    {        // Load the data into a stream        MemoryStream mp3stream = new MemoryStream(data);        // Convert the data in the stream to WAV format        Mp3FileReader mp3audio = new Mp3FileReader(mp3stream);        WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(mp3audio);        // Convert to WAV data        WAV wav = new WAV(AudioMemStream(waveStream).ToArray());        Debug.Log(wav);        AudioClip audioClip = AudioClip.Create("mp3Clip", wav.SampleCount, 1, wav.Frequency, false);        audioClip.SetData(wav.LeftChannel, 0);        // Return the clip        return audioClip;    }    private static MemoryStream AudioMemStream(WaveStream waveStream)    {        MemoryStream outputStream = new MemoryStream();        using (WaveFileWriter waveFileWriter = new WaveFileWriter(outputStream, waveStream.WaveFormat))        {            byte[] bytes = new byte[waveStream.Length];            waveStream.Position = 0;            waveStream.Read(bytes, 0, Convert.ToInt32(waveStream.Length));            waveFileWriter.Write(bytes, 0, bytes.Length);            waveFileWriter.Flush();        }        return outputStream;    }}/* From http://answers.unity3d.com/questions/737002/wav-byte-to-audioclip.html */public class WAV{    // convert two bytes to one float in the range -1 to 1    static float bytesToFloat(byte firstByte, byte secondByte)    {        // convert two bytes to one short (little endian)        short s = (short)((secondByte << 8) | firstByte);        // convert to range from -1 to (just below) 1        return s / 32768.0F;    }    static int bytesToInt(byte[] bytes, int offset = 0)    {        int value = 0;        for (int i = 0; i < 4; i++)        {            value |= ((int)bytes[offset + i]) << (i * 8);        }        return value;    }    // properties    public float[] LeftChannel { get; internal set; }    public float[] RightChannel { get; internal set; }    public int ChannelCount { get; internal set; }    public int SampleCount { get; internal set; }    public int Frequency { get; internal set; }    public WAV(byte[] wav)    {        // Determine if mono or stereo        ChannelCount = wav[22];     // Forget byte 23 as 99.999% of WAVs are 1 or 2 channels        // Get the frequency        Frequency = bytesToInt(wav, 24);        // Get past all the other sub chunks to get to the data subchunk:        int pos = 12;   // First Subchunk ID from 12 to 16        // Keep iterating until we find the data chunk (i.e. 64 61 74 61 ......

再挂个AudioSource，简单粗暴读取文件，解码变为byte[]填充进AudioClip，播放即可

void PlayOGG(){    string path = Application.dataPath + "/../Audio/Music/a.ogg";    byte[] data = File.ReadAllBytes(path);    audioSource.clip = NAudioPlayer.FromOggData(data);    audioSource.Play();}void PlayMP3(){    string path = Application.dataPath + "/../Audio/Music/a.mp3";    byte[] data = File.ReadAllBytes(path);    audioSource.clip = NAudioPlayer.FromMp3Data(data);    audioSource.Play();}void PlayWAV(){    string path = Application.dataPath + "/../Audio/Music/a.wav";    byte[] data = File.ReadAllBytes(path);    audioSource.clip = NAudioPlayer.FromWavData(data);    audioSource.Play();}
