What's the AAC bitrate?
We use Mediabunny's default AAC encoder settings — typically VBR ~128 kbps stereo.
Extract HLS Audio to AAC
Paste an .m3u8 URL or drop a local playlist. We extract a compact AAC file — ideal for podcasts and mobile-friendly delivery.
Frequently asked questions
Is the output an .m4a or .aac?
We output ADTS (.aac). If you need .m4a, use HLS → MP4 with audio-only.
Why does m3u8 fail to load?
Most likely CORS. Use the upload tab when a server blocks cross-origin fetch.
Are multi-language tracks supported?
Primary track only. Multi-audio extraction is on the roadmap.
Will Apple devices play this without conversion?
Yes — AAC is the native audio format on Apple platforms.
Which browsers are supported?
Chrome 105+, Edge 105+, Safari 16.4+, Firefox 130+. WebCodecs is required.
