本來應該發在隔壁樓軟體討論串,但那邊貼圖比較麻煩,就發在這邊了。
用 Audacity 看同一首曲的 wav 檔,上面是 CD rip,下面是從 Qobuz 購買下載的。

這是最討厭的,線上購買的聲音檔,完全無法保證品質!除非讓我好好研究個幾年去抓它的規律......
相對的CD唱片反而安全非常多。等到box不營業我們就麻煩大了!!

有些早點的 CD 就是這樣的審美產物。近期再 remix 的錄音上傳至線上平台就避開了這樣的做法。

兵不厭詐,商場如戰場,因此網店的檔案還是洗洗睡吧:

Unfortunately there is also a way to fake the spectrum itself, meaning, it is possible to turn an MP3-like spectrogram into a FLAC-like "full" spectrogram. I have seen examples of that and they can even fool a person using graphical spectrum analyzers, if they are not experienced. I won't say more about how that's done since I don't want to be giving anyone ideas (I may only explain how to detect such files or send learning examples, if anyone is interested). A well made fake from an already good lossy file may be literally impossible to detect though.

It is now possible to completely fake a FLAC file, meaning you can take an MP3 and run it throught certain procedures and get a file with a full, lossless looking spectrum. There's no way to tell that't fake. Not many of those exists cause most people don't know how to fake them like that, but some do. And there's a website out there now what "restores" lossless files from MP3s. What a scam!

但是個別串流平台還是相當「好玩」的說,例如 DoubleDouble/Lucida/SQUID.WTF 可以無限下載完全免費的 FLAC 檔案。

我真的覺得 LinearPi Pro 與 超級電容 之間用開爾文感應,聲音差超多的...
沒用雖然還是很好聽,但沒那麼乾脆、收放自如、凌厲,動態略小
使用開爾文感應後,動態會稍微變大,結像感變很好,聲音開闊、空氣感與泛音變好、鼓點打擊更精準、高頻再亮麗些...

咦,純粹就waveform來說,
我怎麼覺得上面的「看起來」才是compression過的?
下面的反而處理比較少。
還是我誤解了什麼?

根據經驗,流行音樂比較符合你所說的,也就是所謂『響度戰爭』這種很入門的情況。
但是古典音樂的市場是完全不同一回事,因為很多自以為喜歡古典音樂的人都『不喜歡』細節太多的音樂,所以市場傾向壓縮暫態來減少細節,所以無論是DG、EMI討好市場的『轉錄』,都會傾向把上面那種波形轉錄成下面那種波形,然後聲音就死掉了。
這是三十年前林主惟等前輩發現的聽感,結果音響圈流行的卻是針對流行音樂的『響度戰爭』這種入門話題。可見『真正喜歡』古典音樂的音響迷真的不多.....
所以縱然我們都是『真正喜歡』的古典音樂愛好者,但是要接觸這些『不喜歡古典音樂』的音響知識就要非常小心:他們的聽感與我們相差非常大的。
