※ 引述《pqpq0313 (看不清的双眼)》之铭言： : ※ 引述《ferrarirossa (Sean)》之铭言： : : Google 到了 有兴趣的看一下吧 : : http://www.tweakheadz.com/catalog-mic-preamps1.htm : : What is a Microphone Preamp? : : Think a minute. A microphone actually converts sound energy into voltage. : : But this voltage is very low, MUCH lower than the voltage coming out of your : : keyboard or other line level processors. Your recording device can't use : : this signal unless it boosted massively. Hence the preamp. You already have : : a mic preamp on your computer, but it's only designed for speech and cheap : : mic--totally unsuitable for serious work. You might have Mic preamps on your : : mixer and they may work perfectly. However, sometimes we want a better one : : than is on our mixer. And if you don't have a mixer and are going mixerless, : : then you have to have a mic pre. On this page you will see a lot of : : different preamps that will boost a microphone signal without adding lots of : : noise. Remember that the Mic Pre is one of the "core" devices that provide : : for sound quality. You will see that there are many preamps here. There is : : one for every budget. : : 我看到有美金30~40左右的耶>< 那个好吗? : : 有大大可否推荐一下 : 印象中 : 像这种动圈式的麦克风… : 好像都是要接专业的录音卡 : 然後录音卡会有麦克风讯号扩大器 : 然後声音讯号才会有扩大 : 我自已败了一个录音卡 : 结果只有插麦克风的洞有讯号扩大功能 : 插jack phone的就没有(一般6.3mm的) : 插xlr的才有(也就是插麦克风三个洞的那个头) : 所以… 败录音卡吧 = = 我个人是买 M AUDIO FAST TRACK M AUDIO的还不错啦 我那个老师说 录音卡要买就买有牌点的 这张约四千初吧 如果你是只有在玩VOCAL的而已了话 这张还OK啦 如果还有玩其他乐器了话 就要想一下需不需要 PHONE JACK插口是要有扩大讯号功能的了 USB的印象中是方便啦 但是 好像不少人後 PCI的会比较好的样子 延迟会做到比较好 不过我那个是USB的 目前玩录歌 还没有延迟的现象跑出来 买录音卡就一定要注意到延迟的问题 有些杂牌的会有延迟唷 = =… 而且 CPU好像也要注意的样子 要多媒体运算比较强的 还有啥密浮点运算的… --
