編解碼器列表

下列是壓縮格式和相關編解碼器的列表：

**音頻編解碼**

**非壓縮**
 脈衝編碼調製（Pulse-code modulation，簡稱PCM）是一種非壓縮的音頻編碼格式。此格式是CD-DA的標準。在計算機中，使用 PCM 編碼的音頻可以直接以原始音頻格式 儲存。不過它們通常會被儲存在容器中，如WAV、AIFF、AU等（但在技術上這並不是必須的）。注意，有時 PCM 和 LPCM 都被籠統的稱作 PCM，但實際上它們相似卻不相同。
** 線性脈衝編碼調製（Linear pulse-code modulation，簡稱LPCM）是一種非壓縮的音頻編碼格式。這是一個 PCM 的變種。- 脈衝密度調製（Pulse-density modulation，簡稱PDM）是一種非壓縮的音頻編碼格式。- 脈衝強度調製（Pulse-Amplitude Modulation，簡稱PAM）是一種非壓縮的音頻編碼格式。
