@section{description}

this is also created from a link::Classes/NodeProxy::, or an link::Classes/Ndef:: with the message strong::record::.

@section{ClassMethods}
 

@section{method}
 new
see superclass

@section{method}
 audio
see superclass

@section{method}
 newFrom
instantiate a new proxy that listens to the in proxy.

@section{InstanceMethods}
 

@section{method}
 open
open new file and initialize buffer on server

@section{method}
 record
start the recording synth.

@section{argument}
 paused
if paused is false start recording immediately.

@section{argument}
 clock
optional - the clock to use for scheduling recording ...
@section{argument}
 quant
... if a non-nil quant is given.

@section{method}
 close
stop recording, close file

@section{method}
 isRecording
see if recording right now

@section{method}
 wakeUp
until the proxy is not used by any output ( either .play or .ar/.kr ) it is not running on the server. you can wake it up to force it playing.
