Adjusting the Volume of a Skype Call
Call Recorder records from the audio input (your microphone) without any changes to the volume.
To adjust your own microphone volume level, use the input volume adjustments in the "Input" tab of the Mac's System Preferences "Sound" panel.
To adjust the other person's audio level, use the volume slider control in Call Recorder's control window.
Note that this control is only available in Call Recorder when using Skype 8 or newer. For Skype 7, use the volume slider in Skype's Audio/Video preference panel.
Audio levels can also be adjusted after the call using Ecamm Movie Tools.
