style="text-indent:25px">比特率是大家常聽說的一個(gè)名詞，數(shù)碼音頻一般使用16比特、20比特或24比特制作音樂。什么是“比特”？我們知道聲音有輕有響，影響聲音響度的物理要素是振幅，作為數(shù)碼音頻，必須也要能精確表示樂曲的輕響，所以一定要對波形的振幅有一個(gè)精確的描述。“比特(bit)”就是這樣一個(gè)單位，16比特就是指把波形的振幅劃為2^16即65536個(gè)等級，根據(jù)模擬信號的輕響把它劃分到某個(gè)等級中去，就可以用數(shù)字來表示了。和采樣頻率一樣，比特率越高，越能細(xì)致地反映樂曲的輕響變化。20比特就可以產(chǎn)生1048576個(gè)等級，表現(xiàn)交響樂這類動態(tài)十分大的音樂已經(jīng)沒有什么問題了。剛才提到了一個(gè)名詞“動態(tài)”，它其實(shí)指的是一首樂曲響和輕的對比能達(dá)到多少，我們也常說“動態(tài)范圍”，單位是dB，而動態(tài)范圍和我們音頻時(shí)采用的比特率是緊密結(jié)合在一起的，如果我們使用了一個(gè)很低的比特率，那么就只有很少的等級可以用來描述音響的強(qiáng)弱，當(dāng)然就不能聽到大幅度的強(qiáng)弱對比了。數(shù)字音頻如果記錄格式(采樣頻率、量化)確定，性能的極限也就確定，而且轉(zhuǎn)錄沒有任何損失。徐州線上音頻管理</p><p
