Class BufferedFileOut

java.lang.Object
  ddf.minim.AudioFileOut
      ddf.minim.BufferedFileOut

All Implemented Interfaces:

ARListener

public class BufferedFileOut

extends AudioFileOut

BufferedFileOut is an implementation of the AudioFileOut protocol that records to an in-memory buffer and then writes the data to disk when save() is called. Because of this it is possible to specify the file format to use for saving after the audio has already been recorded. It is also possible to save the recorded audio to multiple formats by calling save(type) for each file format you want to save to. Because the saving is performed in the same thread of execution as your Processing sketch, you can expect your sketch to hang while the audio is written to disk. How long it hangs will be proportional to the length of the audio buffer.
