什么是 OGG 文件？
音质优于 MP3 的开源音频格式
OGG files is a container for storing audio data. It is similar to an MP3 file, but sounds better than an MP3 file of equal size due to its default setting of using variable bit rates. OGG files may also include song metadata like artist information and track data. OGG audio files are popular mainly because it uses a free, unpatented OGG Vorbis audio compression algorithm and is widely supported by most software music players and some portable music players.
OGG primarily uses ‘Vorbis’ encoding which was created by Xiph.Org (the creators of OGG). However, they can also use other types of audio compression (including FLAC and Speex), but those files won’t be referred to as ‘Vorbis audio files.’ Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. Thus, Vorbis audio files are similar in audio quality and reproduction to AAC files, and higher quality when compared to MP3 and WMA files.
OGG 文件的常见用途
- 游戏音频
- 开源音乐分发
- 流媒体音频
- 播客分发
- 电子游戏
- Linux/开源软件
- Spotify（内部格式）
- Web 应用程序
谁会使用 OGG 文件？
独立游戏开发者和开源软件维护者青睐 OGG，因为它免版税且易于嵌入；像 Wikimedia 这样的自由文化项目也依赖它，因为其平台只接受不受专利限制的媒体格式。在 Linux 工作流程中工作的研究人员和播客主播也会遇到它，因为它是 Audacity 等开源录音工具中常见的导出选项。
OGG 与 MP3：应该选择哪一个？
OGG（Vorbis）和 MP3 都是有损压缩音频格式，但在相同比特率下，Vorbis 的主观音质通常优于 MP3，而且它完全开放、免版税。MP3 在各类设备、车载音响和旧版软件上几乎得到普遍支持，因此在最看重兼容性时，它仍是更稳妥的选择。游戏、Web 项目和开源工作流程宜选择 OGG；如果文件必须在任何地方都能播放而无需额外的编解码器，则宜选择 MP3。
