style="text-indent:25px">雙軌立體聲音頻和多軌立體聲音頻的區(qū)別：在實際制作中，雙軌立體聲多采用模擬設備，音質比較好，更人性化，設備連接簡單。多軌立體聲都采用數(shù)字設備，信噪比、動態(tài)范圍、非線性失真指標非常卓著，能夠進行強大的音頻信號處理功能，缺點音質有損失，設備兼容性差。雙軌立體聲音頻在于嚴格再現(xiàn)原有藝術聲場，多軌立體聲音頻是再造新的藝術聲場，二者不僅在技術上有差異，更重要的是在審美上的差別。多軌立體聲音頻給音頻師更為廣闊的藝術創(chuàng)作空間，不僅掌握音頻技術，還必須具備精通的音樂藝術，藝術和技術熔為一爐。雙軌立體聲體現(xiàn)的是“自然的”美，多軌立體聲體現(xiàn)的是“工藝的”美。嚴格再現(xiàn)藝術聲場的雙軌立體聲適用于錄制“整體藝術”，本質是創(chuàng)造一個新的藝術聲場的多軌立體聲適用于錄制非群體藝術。上海上海戲劇學院音頻報名音頻藝術需要掌握聲音設計的方法、聲學、數(shù)字音頻及音樂方面的基本理論和基本知識。</p><div

style="text-indent:25px">拾音器的工作原理和分類：拾音器是一種把聲音信號轉換為電信號的換能器件。有聲學系統(tǒng)、機械系統(tǒng)和電學系統(tǒng)三部分組成。分類：（1）按換能原理分電容傳聲器、駐極體傳聲器、動圈傳聲器、碳粒式傳聲器和壓電式傳聲器。（2）按聲波作用于膜片的不同方式分壓強式、壓差式和壓強壓差復合式。（3）按指向性分全指向性、雙指向性、單指向性和可變指向性。在音頻系統(tǒng)中阻抗匹配問題：電聲設備的連接中，對于前后級阻抗的處理方式有兩種，一種是阻抗匹配，一種是跨接的方式。阻抗匹配就是指前一級設備的輸出阻抗與后一級設備輸入阻抗相等。連接方式是基于大功率傳輸原理。 </p><p style="text-indent:25px">音頻藝術專業(yè)的學生主要學習音樂、廣播、電影、電視音頻等方面的基本理論和基本知識，受到聲音錄制、藝術處理等方面的基本訓練，掌握聲音(音響)設計、音頻節(jié)目制作、藝術處理的基本能力。畢業(yè)生應獲得以下幾方面的知識和能力：1．掌握聲音設計的方法、聲學、數(shù)字音頻及音樂方面的基本理論和基本知識；2．掌握電路分析方法及音頻技術；具有音頻節(jié)目錄制，后期制作及電子音樂制作的基本能力；3．掌握音頻工藝、音頻藝術創(chuàng)作等方面的技術與技巧；4．了解音頻節(jié)日錄制的前沿及發(fā)展動態(tài)；具有初步的科學研究和實際工作能力；5．了解黨和國家關于藝術、新聞、出版的政策和法規(guī)；6．掌握文獻檢索、資料查詢的基本方法。粉紅噪聲：各倍頻程中聲能相等的隨機噪聲，利用粉紅噪聲以及實時頻譜分析儀可以測試聲音系統(tǒng)。</p><div

style="text-indent:25px">壓縮器的功能：壓縮器是一種放大器，具有壓縮閥，低于閥值的輸入信號以固有的增益給予放大，高于閥值的輸入信號則按照特定的壓縮比進行壓縮。一般有門限、啟動時間、恢復時間和壓縮比可調。功能：（1）壓縮器可以避免削波失真，提高信噪比。（2）可以避免電平過高引起信號饋入而保護傳聲器和音箱。（3）在現(xiàn)場擴聲中提高平均電平。（4）對傳聲器、電聲設備信號起到音量平衡作用。（5）改善音質。（6）用于產(chǎn)生所謂的“潛入效果”或產(chǎn)生某些“特技效果音”。人類能夠聽到的所有聲音都稱之為音頻，它可能包括噪音等。上海上海戲劇學院音頻報名</p><p

style="text-indent:25px">我們注意一下身邊的CD片就會看到很多CD都有如：ADD、AAD、DDD等標記。三個字母按順序各表示該片在音頻、編輯、成品三個過程中所使用的方法，是模擬(Analog)還是數(shù)字(Digital)。當然A表示模擬，D表示數(shù)字。AAD就說明其音頻和編輯是用模擬方式的，而然后灌片是用數(shù)字方式的，這類唱片多是將過去錄制的音樂轉成CD片而不做任何修改。ADD則是有一個修改過程。許多古典音樂大師的演奏或指揮多錄制于模擬時代，我們聽到的CD是經(jīng)過修改后灌錄的，很多這類唱片都有標記ADD。而DDD的唱片必然是較現(xiàn)代的音頻品。自然，CD片必然以D結尾，而磁帶可以姑且認為是AAA，雖然好像并沒有這種說法。上海上海戲劇學院音頻報名</p></p><br
