用一般立体声录音机录制外语、报告、讲课等内容时,左右两个声道效果基本相同,立体声在这里没有什么意义。双声道立体声录音机是把磁带分成四路录音和放音的,每面分为左右两路声道。如果在录制语音节日时,每次只用一路声道,就可以使磁带利用率提高一倍,一盒磁带当两盒用。具体方法如下: ①在外录声音时,一般立体声录音是左右声道各一支话筒,此时如果仅使用其中一支,则录下的即为单声道效果,但录制前需进行抹音。此声道录完即可使用另一话筒录在另一声道(此时不能再进行抹音,如果录音设备自带抹音磁头,应将抹音电源切断)。两面都如此录制。 ②如果使用录音机转录,则方法相同,只是将信
When recording a foreign language, a report, a lecture, or the like with a general stereo recorder, the effects of the two left and right channels are basically the same, and stereo does not make any sense here. Two-channel stereo recorder is the tape is divided into four recording and playback, each side is divided into two channels. If you record only one voice track at a time, you can double the tape utilization and use two cassettes of tape. Specific methods are as follows: ① When recording sound, the general stereo recording is a microphone on each of the left and right channels. If only one of the microphones is used at this time, the mono effect is recorded, but the erasing is required before recording. This channel can be recorded using another microphone recorded in another channel (this time can not wipe, if the recording device comes with erase head, wiping power should be cut off). So recorded on both sides. ② If you use voice recorder transcription, the method is the same, just the letter
