Technical Quality Assessment
AU Audio encodes data using mathematical algorithms that preserve every data point. FLV Video similarly focuses on perceptual quality. The conversion maps between these approaches intelligently. AU Audio's known limitation — no compression options, limited metadata — is resolved when converting to FLV Video, which offers compact file size optimized for low-bandwidth streaming. The AU Audio source uses lossless encoding. The FLV Video output uses lossy encoding. This difference in compression approach means Xonvert carefully manages the transition to preserve maximum fidelity.
Converting AU Audio audio to FLV Video video creates a video file with a static visual (typically a black frame or waveform visualization) and your audio track. This is commonly used for uploading music to video-only platforms like YouTube, creating visualizer content, or embedding audio in video projects.
Compression trade-off: Your lossless AU source retains all original data. Converting to lossy FLV will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
