Set up your equipment for recording as you normally would. This includes loading your editing software, such as Pro Tools, Logic or Ableton, and setting a track to its record-enabled state.
Test your gain levels on the interface or mixer before you record by playing the guitar. Make sure the meters on the guitar's track in the program do not clip, or pass 0 decibels. The meter will turn red when clipping occurs to easily identify when you need to reduce gain levels. If a signal clips during recording, you cannot get rid of it.
Listen for any hums or buzzing coming from your speakers. If this occurs, a piece of your equipment is damaged. It will most likely be a cable, but it could also be your guitar, direct box or pedals. It could also be your amplifier or microphone if you are not recording directly into the system.
Replace any damaged equipment.
Record your guitar track. If the strings buzz at all during the recording, it can be altered during the editing phase, but the best option is to rerecord the track until it is perfect. If you need to take your guitar to a professional to adjust its action, use a different guitar or get someone better to play for you, do so because this will give you a higher-quality track than editing out mistakes.
Load a parametric equalizer plug-in with at least four bands on your program if you have already recorded the track and cannot redo it. These programs come with decent equalizers, but the highest-quality plug-ins must be purchased separately.
Make the frequency range of a middle, high middle or high band as narrow as possible and boost it as much as you can, which will be about 12 decibels to 18 decibels.
Drag this band to the left or right to slowly change the frequency range affected by your equalization until the buzz really stands out. Lower the level of this frequency drastically to between -6 decibels and -18 decibels, depending on how much of it you want to remove, as buzz sounds appropriate and natural for certain acoustic guitar recordings.
Copy and paste notes or repeated sections, such as a chorus, where there is no buzz over parts that have a buzz. This may feel like cheating, but it happens a lot in the music industry to put the best sound into a recorded version of a song.
