Subject: [PATCH] Update audio.py

For those of you who have a mono (1 channel) mic, the '-ac' flag should be entered strictly before the '-i device'; if that flag is set after the device declaration, then the setting will apply for the output (as per the man page for ffmepg command). Hope this helps.
