How NUT Handles AU Data
The AU Audio source uses lossless encoding. The NUT Container output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient. Xonvert's conversion engine analyzes your AU Audio source and selects the optimal encoding strategy for NUT Container output. Simple header: magic number, data offset, size, encoding, rate, channels Supports arbitrary number of audio, video and subtitle streams These implementation details are handled automatically by the converter. A/B testing confirms that Xonvert's AU Audio to NUT Container output is indistinguishable from reference-quality conversions produced by leading desktop software. The WebAssembly engine uses identical codec libraries.
Converting AU Audio audio to NUT Container video creates a video file with a static visual (typically a black frame or waveform visualization) and your audio track.
