Xaoc Devices Koszalin Stereo VC Frequency Shifter｜立體聲電壓控制頻率位移模組
Koszalin 是一款為 Eurorack 系統設計的 立體聲 Frequency Shifter（頻率位移器），具備 2 組輸入、4 組輸出，能對立體聲音訊進行真正的頻率位移處理，並支援完整的電壓控制回授（stereo feedback）架構。與常見的 Pitch Shifter（音高轉換）不同，Frequency Shifting 並非依比例改變頻率，而是將整個頻譜做「線性平移」，因此會產生大量非和聲、非調性（atonal）的音色結果。
在 Koszalin 中，所有頻率成分都會被等量地向上或向下位移指定的 Hz 數值，這會破壞原本的倍音關係，形成金屬感、空間錯位感、旋轉感極強的聲音特性。當這種頻率位移再與立體聲回授與相位抵銷效應交互作用時，便能產生極具特色的 barber-pole（無限上升或下降） 幻覺音效。
Koszalin 提供三段頻率位移範圍（50 Hz / 500 Hz / 5 kHz），可從極細微的相位漂移、立體聲寬度變化，一路推進到高度實驗性的聲音解構。模組同時具備 exponential（準指數） 與 linear thru-zero（線性 TZFM） 的調變方式，可對頻率位移量進行精準且可預期的 CV 控制，讓它不只是效果器，更能成為聲音結構的一部分。
在回授設計上，Koszalin 提供完整的內部立體聲回授路徑，並可由電壓控制回授量、回授路由與回授反應曲線。這使得使用者能在穩定、可控與極端自激之間取得細膩平衡，特別適合用於實驗電子音樂、聲音設計、空間音色塑形，以及模組系統中的立體聲處理核心。
雖然 Koszalin 的音訊核心為 DSP 數位處理，但整體操作介面與訊號流皆以 類比控制邏輯 設計，保留即時操作的直覺性與模組系統的手感，兼顧精準度與聲音可塑性。
