Technical Quality Assessment
Convert AU to WAV for modern audio editing For the best results, start with the highest quality FLV Video source file available. AU Audio is known for simple format with wide Unix/Linux tool support. This means your converted output will benefit from AU Audio's core strengths. Meanwhile, the original FLV Video's advantage of compact file size optimized for low-bandwidth streaming may not fully carry over, depending on AU Audio's capabilities. Artifacts — unwanted visual or auditory imperfections — are minimized through Xonvert's tuned encoding parameters. Since AU Audio is lossless, no artifacts are introduced during conversion.
Extracting audio from FLV 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 FLV 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 FLV encoding cannot be recovered.
