標題: [問題] opus音檔轉存選擇
時間: Fri Jan 20 20:45:26 2017
因為自己有喜歡的youtube cover,苦無這些都沒有無損或是CD可以收藏,
在無數的爬文後,找尋youtube最高音質的下載方法,最後用mps-youtube下載webm檔(只
含聲音),再經由ffmpeg提取出來,但原生提取出來的檔案是opus,而大多數播放器,或
是音樂app都不支援,於是想請問如果想轉成大眾通用的格式,要如何保持原本的音質呢?
我試過
1. 如果直接轉有損壓縮,例如mp3、acc、ogg等,用Audacity看頻譜,訊號量少有點多
,目前是選擇ogg,然後品質調10,出來的最接近opus原檔。
2. 如果轉無損壓縮flac,頻譜多了些莫名的訊號...
3. 如果轉存成wav,頻譜完全相同,但檔案大小變超大......,有點本末倒置
比較以上,轉成ogg、flac、wav,其實和原本opus的聽感無太多差異,不過心中總會有些
轉檔造成損失的哀傷與疙瘩啊!
想請問大大,像這樣壓縮格式如果要完全不失真的轉存成其他格式,有什麼方法嗎?
謝謝!
覺得本版跟耳機版比較會有這類的發燒友,也麻煩大神們回覆啦!
感激不盡<(_ _)>
