style="text-indent:25px">模擬音頻技術(shù)和數(shù)字音頻技術(shù)的優(yōu)缺點：模擬音頻在記錄、編輯、重放過程中進來的雜音不能與有用信號分開，噪聲呈積累性質(zhì)，信號轉(zhuǎn)錄受到極大的限制。而數(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。模擬音頻中記錄的媒質(zhì)的信噪比代替了原信號的信噪比，而數(shù)字音頻信噪比和重放信號的信噪比沒有直接關(guān)系，記錄重現(xiàn)性比較好。模擬音頻中對錄放磁頭等換能器要求高，如果有非線性原信號就會出現(xiàn)非線性。數(shù)字音頻中記錄信號和噪聲是兩種不同的東西，因此分開不會引起噪聲，也不存在噪聲積累。模擬音頻中旋轉(zhuǎn)系統(tǒng)、驅(qū)動系統(tǒng)等機構(gòu)動作不穩(wěn)定就會引起信號抖晃，而數(shù)字音頻中在重放系統(tǒng)中時基校正電路的作用，不穩(wěn)定也不會引起抖晃，信號質(zhì)量大幅度提高。安徽東華大學音頻管理音頻的格式：要在計算機內(nèi)播放或是處理音頻文件，也就是要對聲音文件進行數(shù)、模轉(zhuǎn)換。</p><div

style="text-indent:25px">比特率是大家常聽說的一個名詞，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精確的描述?！氨忍?bit)”就是這樣一個單位，16比特就是指把波形的振幅劃為2^16即65536個等級，根據(jù)模擬信號的輕響把它劃分到某個等級中去，就可以用數(shù)字來表示了。和采樣頻率一樣，比特率越高，越能細致地反映樂曲的輕響變化。20比特就可以產(chǎn)生1048576個等級，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。剛才提到了一個名詞“動態(tài)”，它其實指的是一首樂曲響和輕的對比能達到多少，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弱，當然就不能聽到大幅度的強弱對比了。</p><p style="text-indent:25px">基于雙工理論，同樣地，只要把一個普通的雙聲道音頻在兩個聲道之間進行相互混合，便可以使普通雙聲道聲音聽起來具有三維音場的效果。這涉及到以下有關(guān)音場的兩個概念：音場的寬度和深度。音場的寬度利用時間差的原理完成，由于是對普通立體聲音頻進行擴展，所以音源的位置始終在音場的中間不變，這樣就簡化了我們的工作。要處理的就只有把兩個聲道的聲音進行適當?shù)难訒r和強度減弱后相互混合。由于這樣的擴展是有局限性的，即延時不能太長，否則就會變?yōu)榛匾?。音場的深度利用強度差的原理完成，具體的表現(xiàn)形式是回聲．音場越深，則回音的延時就越長．所以在回音的設(shè)置中應(yīng)至少提供三個參數(shù)：回音的衰減率、回音的深度和回音之間的延時。同時，還應(yīng)該提供用于設(shè)置另一通道混進來的聲音深度的多少的選項。音頻是個專業(yè)術(shù)語，音頻一詞已用作一般性描述音頻范圍內(nèi)和聲音有關(guān)的設(shè)備及其作用。</p><div
