Noise can be a big problem when trying to record into a computer. Reducing and canceling out noise using several simple techniques will help increase recording quality and increase your satisfaction with recordings. Solutions range from complete room overhauls to simple changes in the placement of the microphone and other objects in the recording.
Use a stabilized microphone to reduce vibrations. Many hand-held or headset microphones will pick up on vibrations and movements from the user. These vibrations can carry over into the recording and reduce the quality of the recording. Using a microphone stand or stationary microphone will reduce noise while recording. Mic stands will help increase recording quality and off a possible solution that requires very little financial investment. Set up a designated sound room that is set away from the rest of your home. The farther the recording area is from windows and doorways, the better. Windows allow very small amounts of noise to filter in from the outdoors and create white noise in the recording. Hang blankets on the walls around the recording station and use many rough objects in the recording room. Sound travels in waves that bounce back and forth between smooth objects. Blankets and other rough objects will help reduce sound vibrations. These additions to the recording room will reduce ambient sounds from both the room and outside the building by blocking sound waves from bouncing back and forth in the room. If you can make a considerable investment in the room, there are several acoustic products on the market than help nearly eliminate echoes and outside noises. Install software that filters out unwanted sounds and echoes. Many computer applications exist that use programs to increase the quality of recordings and reduce the ambient noise levels in a recording room. Software is used to reduce echoes and feedback in a recording studio. Several free applications can be used to achieve the desired effects when recording. A program called Audacity is one of the most effective software packages that can help reduce noise in recordings. http://audacity.sourceforge.net/
Software can also be used to reduce electronic humming and other white noise that can be picked up during a recoding session. Buy a high-quality microphone with noise and echo cancellation. One of the best investments that a recording specialist can make is a high-quality mic. The microphone itself can reduce many unwanted noises and echoes in the recording room by filtering the actual sounds that are recorded.
