I get both.

 want to switch files.

 close() manually--perhaps it should even be private?

 

I don't think making close() private is really the right solution. I'm recording distinct conversations so having an open() unmute() mute() close() sequence per call makes the most sense (if a channel is idle for 20 minutes between transmissions then I'm going to have the last wav file open for 20 minutes; unless I open a temporary file to write nothing to, which just seems silly).
