編解碼器列表
下列是压缩格式和相关編解碼器的列表:
音频编解码
非压缩
- 脉冲编码调制(Pulse-code modulation,简称PCM)是一种非压缩的音频编码格式。此格式是CD-DA的标准。在计算机中,使用 PCM 编码的音频可以直接以原始音频格式 储存。不过它们通常会被储存在容器中,如WAV、AIFF、AU等(但在技术上这并不是必须的)。注意,有时 PCM 和 LPCM 都被笼统的称作 PCM,但实际上它们相似却不相同。
- 线性脉冲编码调制(Linear pulse-code modulation,简称LPCM)是一种非压缩的音频编码格式。这是一个 PCM 的变种。
- 脉冲密度调制(Pulse-density modulation,简称PDM)是一种非压缩的音频编码格式。
- 脉冲强度调制(Pulse-Amplitude Modulation,简称PAM)是一种非压缩的音频编码格式。
