Automate file creation

To automate file creation of similarly named stereo sound files (for example, soundbite1, soundbite 2, etc), this patch allows you to send the desired file name into the left inlet, then a message to start recording into sfrecord~ and a 0 to stop recording. The audio you want to record is expected in the second and third inlets.

Each time you send in the file name (a single word, which Max considers to be a message of type symbol), the patch increments the number, attaches it to the end of the file along with the .aif suffix, and prepends the word open, so that the sfrecord~ object opens a file of that name. When you stop recording with a 0 message, the file is automatically closed.
