摘要： The present invention includes apparatuses, methods, computer readable media and systems comprising means for using a portable, handheld electronic device (such as Apple's iPod™) to capture analog signals, convert them into digital signals and store the digital signals as media files (e.g., audio files, video files, image files, etc.). The electronic device can subsequently be used to modify the media files. The modifications can be virtual modifications, in which metadata is stored on the electronic device in a manner that does not alter the media file. The virtual modifications can be used by the electronic device to give the perception to the user that a media file has been actually modified. In addition, the virtual modifications can be used by an application running on a host device, such as a home computer or network server (like Apple's .MAC™ servers), to actually modify the digital media file.
