miniDSP官網的說明是這樣寫:
We provide two calibration files to be used depending on your application.
- For stereo system (e.g. 2ch dirac live, single speaker measurement), use the 0deg file and point the UMIK-1 at the speakers
- For multichannel system (E.g. 5.1/7.1) or a surround application where multiple speakers are spreadout around the room, use the 90deg file and point the UMIK-1 at the ceiling.
測兩聲道時,朝向前方;測環繞多聲道時,則朝向天花板,所以我們朝向前方測
還是即使測兩聲道的空間效應時,也應該朝向天花板才對?
不過我現在回想起來,我們昨天測左右個別聲道時,忘記把麥克風朝向喇叭單體,而是朝向兩個喇叭的中間,這樣應該會有很大的誤差
