Opening Audio Files
To open audio files or import video files, go to File|Open and select a supported audio or video file. Alternately, you can also drag and drop files directly into RX to open them.
Audio formats supported - WAV, Broadcast WAV, AIFF, MP3, WMA
Note: Mono audio files with (.L and .R) as well as (.1 and .2) extensions can also be opened as either mono files or split stereo. See 'Edit -> Preferences -> Misc(tab)' to control this behavior.
Importing Video
RX can import the audio directly from a number of video formats, saving you the step of extracting that audio in a separate application. Once you've worked with the audio in RX, you can export that audio and re-assemble the video in your video editing program of choice.
Video formats supported - AVI, MPEG, Windows Media Video, DV, MOV, M4V
