How AU Handles RM Data
Color accuracy is a priority in this conversion. Xonvert maintains data integrity across the format boundary. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. AU Audio preserves all data losslessly, so output size depends on the content's inherent compressibility. Convert AU to WAV for modern audio editing For the best results, start with the highest quality RealMedia Video source file available.
Extracting audio from RealMedia Video video to AU Audio format strips the video track and saves only the audio content. This is perfect for extracting music from music videos, saving podcast audio from video recordings, or creating audio-only versions of lectures and presentations. The audio quality depends on the original video's audio track bitrate and codec.
Important: Converting from lossy RM to lossless AU does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original RM encoding cannot be recovered.
