| name | Name of clip. |
| lengthSamples | Number of sample frames. |
| channels | Number of channels per frame. |
| frequency | Sample frequency of clip. |
| _3D | Audio clip is played back in 3D. |
| stream | True if clip is streamed, that is if the pcmreadercallback generates data on the fly. |
| pcmreadercallback | This callback is invoked to generate a block of sample data. Non-streamed clips call this only once at creation time while streamed clips call this continuously. |
| pcmsetpositioncallback | This callback is invoked whenever the clip loops or changes playback position. |
AudioClip A reference to the created AudioClip.
Creates a user AudioClip with a name and with the given length in samples, channels and frequency.
Set your own audio data with SetData. Use the PCMReaderCallback and PCMSetPositionCallback delegates to get a callback whenever the clip reads data and changes the position. If stream is true, Unity will on demand read in small chunks of data. If it's false, all the samples will be read during the creation.
