Loading at runtime a file into an AudioClip

Unity Engine
1

There is something to open the specified audio (from the file system) into a given AudioClip?

something like:
clip = new AudioClip(filename);

or something similar to the UnityEngine.WWW but which works on the local file system? like:
clip = new WWW(filename).oggVorbis;

I need to load at runtime an audio file (a wave) into an AudioClip to play it.
Can you help me, please?
Thanks.

Its a bit puzzeling that AudioClip doesn’t have a constructor taking a byte array like Texture2D does, but couldn’t you just use the WWW class via “file://”?

I will try
Thanks

Someone knows a dll or a piece of c# code to convert wav to ogg?

Since I use wav and WWW uses only ogg I need to convert them on the fly…

I am trying to translate a piece of C code to C# code to convert a WAV to OGG:

The piece of C code is “examples/encoder_example.c”
in this archive: http://downloads.xiph.org/releases/vorbis/libvorbis-1.2.0.zip

This is what I did:

        [StructLayout(LayoutKind.Sequential)]
        public struct WaveHdr
        {
            public IntPtr lpData; // pointer to locked data buffer
            public int dwBufferLength; // length of data buffer
            public int dwBytesRecorded; // used for input only
            public IntPtr dwUser; // for client's use
            public int dwFlags; // assorted flags (see defines)
            public int dwLoops; // loop control counter
            public IntPtr lpNext; // PWaveHdr, reserved for driver
            public int reserved; // reserved for driver
        }


        public struct vorbis_info
        {
            public int version;
            public int channels;
            public long rate;
            public long bitrate_upper;
            public long bitrate_nominal;
            public long bitrate_lower;
            public long bitrate_window;
            unsafe public void* codec_setup;
        }

        [DllImport("vorbisenc.dll")]
        unsafe public static extern int vorbis_encode_init(vorbis_info* vi, long channels, long rate, long max_bitrate, long nominal_bitrate, long min_bitrate);

        vorbis_info vi;
        int ret;

        unsafe public void ConvertToOGG (String filename)
        {
            fixed (vorbis_info* ptr = &vi){
                ret = vorbis_encode_init(ptr, 2, 44100, -1, 128000, -1);
                if (ret != 0) return;
            }
            
            
        }

I get an error at the line:
ret = vorbis_encode_init(ptr, 2, 44100, -1, 128000, -1);
it that says that it can not find the dll…
I don’t know how to successfully import/use that function… please, help me!

P.S.: I attach the vorbisenc.dll I used

I receive always “DllNotFoundException”
I have put the Dll in the same directory of the executable and also in C:\WINDOWS\System32…
Is the dll that doesn’t work? Or I made other mistakes?

Someone can help me?
If someone has the “vorbisenc.dll” working in windows, please post it.
