WAV to AAC Converter
Runs in your browser — your files are never uploaded.
Convert WAV to AAC as a raw ADTS stream — a genuine .aac file, not an MP4 container with the extension changed. That distinction matters: .aac and .m4a hold the same codec in different wrappers, and hardware that asks for .aac generally means the bare stream and refuses anything else. AAC beats MP3 at the same bitrate, which is why it became the default for streaming and broadcast.

Frequently asked questions
What is the difference between .aac and .m4a?+
The container, not the codec. A .m4a is AAC inside an MP4 wrapper, which can carry chapters, artwork and metadata. A .aac is the raw ADTS stream with none of that. Renaming one to the other produces a file many players reject, because they parse the container before the audio.
Is AAC better than MP3?+
At the same bitrate, generally yes — noticeably so below about 128 kbps, where AAC holds together and MP3 starts to sound watery. Above roughly 192 kbps both are transparent for most listeners and the difference stops mattering.
Which should I choose for compatibility?+
MP3, still. AAC support is near-universal on anything made this century, but MP3 is the one format that genuinely plays everywhere including much older hardware.
