CARMA V4.0 - 電腦輔助 空間分析軟體

Computer Aided RooM Analyzer, Version 4.0

 

 

     長期以來,音響與空間的關聯性,雖廣受重視卻難以駕馭掌控。雖然專業領域早有頻譜分析儀可供應用探索、雖然有些 Hi-End 廠家也曾推出高價數位前級並配置自動偵測、修補之空間調整功能,然一者設備昂貴、接觸不易,二來自動修正會因某些空間狀況而失效,最後使人質疑、望而怯步。於是乎從幾萬元的入門系統,上至百萬音響、百萬空間裝潢,最後大多只能以經驗法則調聲,雖此為必要步驟,卻易成瞎子摸象,暨無科學驗證亦欠缺效率。

 

 

 


 
   凝聚頂尖音響技術之德國 Audionet 公司,於此推出自行研發的空間聲學分析軟體 - CARMA,只要有 PC Notebook,另加一只合宜之量測麥克風與麥克風擴大器,您就可輕易架設自己的分析系統。CARMA V4 可以是一架頻譜分析儀,能精確顯示任何空間響應與聲學狀況;CARMA V4 更是一位科學顧問家,不論是 Stereo 2.0/ 2.1 Multi-Channel 7.1,每個聲道皆能獨立測試、分析,是您調整喇叭擺位與聆聽位域的最佳幫手。
