康少音嚮跌宕控制 志兄﹕ 多謝！上次在深圳回港過關時行李太多，全靠你幫忙，否則唔知點算， 你音樂社用的是Soundcraft Ghost LE32 32 Ch Mixer，這個牌子在美國不什流行，亦很貴，在這裡二手貨亦要六千多美元。我很奇怪為何在深圳的樂社這樣受歡迎。你可到SoundCraft的網址下載User Guide. http://www.soundcraft.com/download.asp?filename=pdf/user_guides/ghost/ghost_user_guide_pages1_184.pdf http://www.soundcraft.com/download.asp?filename=pdf/user_guides/ghost/ghost_user_guide_pages185_216.pdf 我當時太匆忙未及回答你的有關跌宕的控制問題，現附上答案，可惜我不知這些專有詞中文叫甚麼，希望你自己查字典或叫朋友翻譯。 Dynamic processors are devices that regulate the amount of sound or energy that is allowed to pass through the mixer. This amount is defined as the dynamic range----the range between the softest sound and the loudest sound. Dynamic processors can be classified into 4 types: compressors limiters gates expander Dynamics compressors The compressor ’s job is to compress the dynamic range of the sound. The purpse is to eliminate transients(usually loud notes or undesirable feedbacks) that can create clipping(dynamic distortion). The compressor limits not only how loud a note can be, but it also reduces the difference between the loudest and softest note (compressing the dynamic range.) Compressors are used extensively on vocals; the device keeps transients at bay by gently reducing the highest level that goes through it Compressors are also used in mastering, to raise the overall volumes of a song without creating distortion. The device does this by reducing the overall dynamics range; as a result, a compressor effectively raises the volume of the softer notes without allowing the louder notes to be too loud and distorting. limiters A limiter works much like the compressor, except it severely limits the highest level of a sound souce. The limiter is basically a compressor on steroids; it gives you beefed-up control on volume. Any signal above a certain level, called the threshold, gets chopped off rather than compressed (as with the compressor). A limiter is a good choice in extreme conditions, such as when you want a really in-your-face 定音鼓 sound. In this instance, the limiter eliminates any dynamic variation from the 定音鼓 and make all the hits sound only as loud as a certain level. The effect is, the musician sitting just next to the定音鼓 can still tolerate the loud sound coming to just one of his ears. gates A gate is basically the opposite of the limiter. Rather than limiting how loud a note can get, the gate limits how soft a note can get. The gate filters out any sound below a certain setting (the threshold) while allowing any note above that threshold to be heard. Gates are often used on vocals 多餘的尾音or on percussions 忘記收音from bleeding through. Another common usage is to keep the 鑼的餘聲(忘記收音) from being heard when the 鑼is not supposed to be played. expander An expander is basically the opposite of a compressor----instead of attenuating (reducing the volume of) the loudest notes in the singing, an expander attenuates the softest notes. For example, if you have a singer whose breath you can hear in the mic and you want to get rid of that particulare blemish, just set the expander to go on at a level just above the annoying breath sounds and it will drop out the breathing sounds subtly. 《代 思 菩 ...》
