The tool re-encodes your uncompressed WAV with AAC, the codec behind YouTube and most streaming platforms. You get a fraction of the file size with quality that, at the same bitrate, generally edges out MP3.
Output is a raw .aac stream (ADTS). Some encoding pipelines and broadcast tools ask for exactly this. If you want AAC for everyday playback with tags and cover art, M4A is the friendlier package.
Raw .aac: for tools and pipelines that explicitly want an ADTS stream. M4A: same AAC audio in an MP4 wrapper with metadata support, ideal for Apple devices and general use. MP3: lower efficiency but unmatched compatibility with old hardware.
When in doubt for personal listening, choose WAV to M4A instead.
Audio Data Transport Stream, the framing used for standalone .aac files. It carries the AAC audio with sync headers so players and streaming tools can decode it directly.
No, raw AAC streams have no tag container. Convert to M4A if you need embedded artwork and titles.
No. The encoder runs inside your browser, so the file stays on your machine from start to finish.
