【编解码器列表】
下列是压缩格式和相关编解码器的列表：
== 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。
=== 无损压缩 ===
