How do I convert an AU audio file to FLV?

Upload your AU file to the converter, select FLV as the output format (choose desired audio codec like MP3 or AAC if needed), then click 'Convert'. Once processed, download the FLV file. The entire process takes seconds and handles batch conversions as well.

Why would I need to convert AU to FLV?

AU is a legacy audio format common on Sun/NeXT systems, while FLV is a container widely used by Adobe Flash Player and many streaming platforms. Converting AU to FLV allows the audio to be embedded in Flash applications, streamed over the internet, or played in video editors that recognize FLV instead of AU.

What happens to audio quality and metadata during AU to FLV conversion?

Audio from the AU file is re-encoded to an FLV-compatible codec (usually MP3 or AAC). If the original AU is PCM uncompressed, you can choose lossless or high-bitrate encoding to preserve sample rate and bit depth. Metadata like artist and title may be retained depending on your settings, but some tags might be stripped. The converter ensures channel count and sample rate are maintained when possible.
