下列是壓縮格式和相關編解碼器的列表:
音訊編解碼
非壓縮
- 脈衝編碼調製(Pulse-code modulation,簡稱PCM)是一種非壓縮的音訊編碼格式。此格式是CD-DA的標準。在電腦中,使用 PCM 編碼的音訊可以直接以原始音訊格式 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)是一種非壓縮的音訊編碼格式。這是一個 PCM 的變種。
- 脈衝密度調製(Pulse-density modulation,簡稱PDM)是一種非壓縮的音訊編碼格式。
- 脈衝強度調製(Pulse-Amplitude Modulation,簡稱PAM)是一種非壓縮的音訊編碼格式。
