Lo-fi recordings sound unclear, thin, or rough, often with extra noises — hiss, hum, room sound, a cheap microphone, tape crackle. The name is short for low fidelity: the recording does not stay close to the clean, full sound you would hear in the room (that clean ideal is hi-fi, high fidelity).

Lo-filo-fi recordings錄音 sound unclear, thin, or rough聽起來不清楚、單薄或粗糙，often with extra noises常常帶著多餘的雜音 — hiss嘶嘶聲，hum嗡嗡聲，room sound房間的環境音，a cheap microphone便宜麥克風的音質，tape crackle錄音帶的雜訊。 The name這個名字 is short for low fidelity是 low fidelity（低傳真）的縮寫：the recording錄音 does not stay close to the clean, full sound you would hear in the room沒有貼近你在現場聽到的那種乾淨、飽滿的聲音（that clean ideal is hi-fi, high fidelity那個乾淨的理想狀態就是 hi-fi，高傳真）。

In older technical talk, lo-fi was a fault: a bad radio, a fuzzy cassette. Though actually, many musicians now choose that rough sound on purpose. Bedroom albums, some hip-hop, and a whole ‘lo-fi’ playlist style treat the hiss and the softness as a mood, warm and homemade, not as a mistake.

In older technical talk在比較舊的技術用語裡，lo-fi was a fault以前 lo-fi 是一種缺陷：a bad radio像是收訊不好的收音機，a fuzzy cassette或是音質模糊的卡帶。 Though actually不過其實，many musicians現在很多音樂人 now choose that rough sound on purpose是刻意選擇那種粗糙的聲音。 Bedroom albums臥室錄製的專輯，some hip-hop一些嘻哈音樂，and a whole 'lo-fi' playlist style還有整個「lo-fi」播放清單風格 treat the hiss and the softness as a mood, warm and homemade把那種雜音和柔和感當成一種溫暖、手作感的氛圍，not as a mistake而不是當成缺陷。

So the same word can be a complaint (‘this file is too lo-fi to use’) or a compliment (‘I love how lo-fi this track is’). It is informal, used by people who talk about music, podcasts, and gear.

So所以 the same word同一個字 can be a complaint可以是抱怨（'this file is too lo-fi to use'「這個檔案太 lo-fi，沒辦法用」）or a compliment也可以是稱讚（'I love how lo-fi this track is'「我很喜歡這首歌的 lo-fi 感」）。 It它 is是 informal很口語，used by people who talk about music, podcasts, and gear是聊音樂、Podcast 和器材的人在用的說法。

As a noun, lo-fi can mean that style of music. It is not a word for ‘low five’ or for Wi-Fi.

As a noun當名詞用的時候，lo-filo-fi can mean that style of music可以指這種音樂風格。 It它 is not a word for 'low five' or for Wi-Fi不是「low five」（擊掌）或「Wi-Fi」的意思。
