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's interface to open them.
Audio formats supported - WAV, Broadcast WAV, AIFF, MP3, WMA
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
Transport
To start and stop playback, use the transport. The transport controls allow you to play, stop, rewind and loop sections of audio.
Rewind [Return] - brings you back to the start of the file
Play [Spacebar] - starts playback
Play selected - when you've made a selection of a time range, frequency range or both, this button auditions just the selection (useful for isolating intermittent noises and applying spectral repair, etc.)
Loop [Ctrl+L] - enable this switch to loop the selected audio
Configuring Audio Settings
If you're using more than one sound card, or are experiencing unpredictable playback or no audio, be sure to check your Audio Hardware settings under the Edit|Preferences menu. Make sure you have selected the sound card or audio device you want to output to, and that the buffer settings are high enough for your computer's processing capabilities.
