'录音档' literally combines '录' (to record), '音' (sound/audio), and '档' (file, short for '档案' or '文件'). Together, it means an audio recording file — a digital file containing captured sound, such as speech, music, or ambient noise. It’s commonly used in everyday tech contexts: saving voice memos, lecture recordings, interview clips, or podcast drafts on computers or smartphones.

This term is neutral in register and widely understood across mainland China, Taiwan, and Singapore. Unlike the more formal '音频文件' (audio file) or technical 'WAV/MP3文件', '录音档' emphasizes the *origin* of the file — that it was recorded, not generated synthetically or downloaded. It often appears in file management interfaces, messaging apps ('send voice memo as recording file'), or when backing up spoken content for later review.
