買無損音樂檔案的坑

嗨嗨嗨, 大家一般公認CD是音質最高的來源,但假如你自己有把CD上面存放的AIFF檔拉下來,會發現都是很統一的44.1kHz 16bit。 實際上呢,44.1kHz是取樣率,代表每秒取樣44100 次=最高22050Hz頻率的音波都可以被錄製到。16bit則代表的是每次取樣的深度,也就是要用多少的1和0來表示音波當前的位置資訊。 電子音頻檔案是把空氣分子震動的類比信號(Analog Signal)轉換成電子信號(Digital Signal)的過程。這就和相機把影像紀錄到一格一格像素本質上是一樣的。更高的取樣率(Sample Rate)和更高的位元深度(Bit Depth)和更高像素的照相機一樣,是在用更多的資訊還原類比信號。因此理論來說,這兩個數值越高,就更能還原音頻原來的樣子,音頻質量也就越好。 當然,這也和輸出設備非常有關。480p的顯示屏播放不出4k視頻的震撼,爛耳機也播放不出如此細膩的電子信號。但這就是另一篇文章要說的事了。
