※ 引述《pqpq0313 (看不清的雙眼)》之銘言： : ※ 引述《ferrarirossa (Sean)》之銘言： : : Google 到了 有興趣的看一下吧 : : 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>< 那個好嗎? : : 有大大可否推薦一下 : 印象中 : 像這種動圈式的麥克風… : 好像都是要接專業的錄音卡 : 然後錄音卡會有麥克風訊號擴大器 : 然後聲音訊號才會有擴大 : 我自已敗了一個錄音卡 : 結果只有插麥克風的洞有訊號擴大功能 : 插jack phone的就沒有(一般6.3mm的) : 插xlr的才有(也就是插麥克風三個洞的那個頭) : 所以… 敗錄音卡吧 = = 我個人是買 M AUDIO FAST TRACK M AUDIO的還不錯啦 我那個老師說 錄音卡要買就買有牌點的 這張約四千初吧 如果你是只有在玩VOCAL的而已了話 這張還OK啦 如果還有玩其他樂器了話 就要想一下需不需要 PHONE JACK插口是要有擴大訊號功能的了 USB的印象中是方便啦 但是 好像不少人後 PCI的會比較好的樣子 延遲會做到比較好 不過我那個是USB的 目前玩錄歌 還沒有延遲的現象跑出來 買錄音卡就一定要注意到延遲的問題 有些雜牌的會有延遲唷 = =… 而且 CPU好像也要注意的樣子 要多媒體運算比較強的 還有啥密浮點運算的… --
