This is a fragment from the aria ah mes amis at a lower pitch and badly performed. Iintend to use it for a Coursera homework (Audio Signal Processing for Music Applications). The intention is to transpose it and simulate a morfing like a falseto to the true key where the tenor hits high C, which I obviously cannot hit, otherwise I wouldn't be taking Coursera courses and uploading to freesound... lowpitchTenor.wav 聲道:1 類型:wav ah-mes-amis、transpose、tenor、low-pitch 哦,我的,朋友、顛倒、男高音、低間距 資料來源:freesound ( https://freesound.org )
