AAC

Advanced Audio Coding (ADTS stream)

Lolly opens and makes this format

Bare AAC audio: the same lossy codec as M4A without the MP4 wrapper, as an ADTS stream that most players and broadcast tools take directly. Lolly adds an .aac to your library and decodes it on your device for a music bed. A Design sequence, or Download as on an audio file in your library, writes one with the same AAC-LC encoder as M4A, in browsers that provide that encoder. A bare ADTS stream has no place for a Content Credential, so choose M4A when the file should carry one.

大多数同类工具都是上传型网站：你的文件会上传到他们的服务器，广告为此买单。Lolly 运行在你的设备上，因此你的文件始终留在你身边。
