OGGからAACへの変換について
OGG Vorbis is Xiph.org's open-source lossy codec, valued for its superior quality-per-bitrate and patent-free licensing. AAC (Advanced Audio Coding) is the industry-standard lossy codec adopted by Apple, YouTube, Spotify, and every major streaming platform. AAC provides excellent quality and is natively supported on iOS, macOS, Android, Windows, and all modern web browsers.
Converting OGG to AAC moves your audio from the open-source Vorbis codec to the universally adopted standard. While Vorbis and AAC have similar quality at medium bitrates, AAC has dramatically wider device support — particularly on Apple devices where OGG is not natively playable.
OGGをAACに変換する理由
Apple's entire ecosystem — iPhone, iPad, Mac, Apple Watch, HomePod, AirPods — cannot play OGG Vorbis natively. AAC is Apple's native audio codec with hardware-accelerated decoding on every device. If your audience includes Apple users (which is roughly 50% of mobile users in the US and UK), AAC compatibility is essential.
AAC is also the required codec for many distribution platforms. The iTunes Store, Apple Podcasts, YouTube, and most commercial streaming services use AAC. Converting OGG to AAC enables distribution through these channels without platform restrictions.
