If the sound jumps during the preview, lower it (11025 is still fine, 5000 is tolerable). buffersize The sound is not generated all at once, but rather made by bunches of frames (chunks). ``buffersize`` is the size of such a chunk. Try varying it if you meet audio problems (but you shouldn't have to). nbytes: Number of bytes to encode the sound: 1 for 8bit sound, 2 for 16bit, 4 for 32bit sound. 2 bytes is fine. audio_flag, video_flag: Instances of class threading events that are used to synchronize video and audio during ``VideoClip.preview()``. iDT) chunksizequantizerfpsFN)rErr iter_chunkssetr/r+) cliprE buffersizer audio_flag video_flag previewer first_framechunks rffplay_audiopreviewrOgs< xxC((C sFDNN ;*y %% 4C& *E# )NN$)OO%  " "5 ) ****s ABB)Nir=NN) rA subprocessrmoviepy.configrmoviepy.decoratorsr moviepy.toolsrrrOr6rrrTs8((05ZZzKO2*2*r
