Frap Tools FUMANA 是一款 Eurorack 濾波器模組,為全類比的雙組濾波器陣列(dual filter bank),可動態存取並編輯訊號的頻段,實現 16 頻段的類比頻譜轉移(spectral transfer)。
FUMANA 是一款全類比的雙組濾波器陣列,具備多種控制以動態存取這些頻段。每組濾波器陣列由 16 個獨立的 48dB/oct 帶通濾波器構成。擁有兩組相同的濾波器陣列,讓你可以用其中一組進行頻譜分析(針對調變訊號),另一組進行頻譜再合成(針對主訊號)。每組陣列再細分為奇數與偶數頻段(由左至右從 1 到 16 遞增編號)。可對奇數與偶數頻段施加不同訊號,主陣列與/或調變陣列皆可。再加上連接到調變濾波器陣列每個頻段的 16 個包絡追蹤器(envelope followers),以及連接到主濾波器陣列每個頻段的 16 個 VCA,FUMANA 得以執行 單組 16 頻段或雙組 8 頻段的類比頻譜轉移。
上半部區段提供每個主濾波器的直接輸出,下半部區段則有 4 個可電壓控制的參數,用以管理兩個獨立功能進行進一步的頻譜編輯:tilt 與 parametric scan。
tilt,如其名稱所示,會傾斜頻譜,對 16 個頻段增加與減去振幅,強調低頻或高頻頻段,並衰減高頻或低頻頻段:這只透過綠色電位器來管理。
parametric scan 則使用三個參數運作:peak/notch、頻段選擇器與 width。如同在參數式等化器中可設定 peak/notch 增益、頻率與斜率,FUMANA 使用三個參數來設定要對哪個中心頻段進行操作、該頻段應被強調或衰減,以及此動作如何延伸到鄰近頻段。
除了 16 個帶通輸出之外,另提供 4 個輸出:all bands 輸出、all envelope followers 輸出、odd bands 與 even bands 輸出。後兩者可透過兩個切換開關進行相位反相,以便在相加時獲得更多組合,例如也可與「all bands output」一起,搭配像 333 模組來使用。
由於頻譜轉移工具可作為「類 vocoder 效果」使用,FUMANA 提供一個外部 noise 輸入,可用於 unvoiced(fricative/sibilants)聲音,例如含有或以 s、f、z、ch 及其他擦音開頭的字([s] [z] [ʃ] [tʃ] [dʒ] [ts] [ʂ] [f] [v] [ɸ] [θ] [ʒ] 等等)。
