For guitarists, miking guitar acoustic will be quite difficult because there are countless factors that make the guitar sound quality not as desired.
In this article, we will provide readers with effective methods to record the best acoustic guitar sound possible.
1.Choosing the right space to record acoustic guitar sound
The first factor that you need to pay attention to before you start placing the microphone is the recording position. In fact, the guitar sound will be affected by the shape and sound of the room due to the sound of hitting each other.
Therefore, choosing the right position when recording guitar is really necessary. As you know, a room often has many hard surfaces, so it will produce thousands of sound reflections.
With spacious rooms, the acoustic reflection will make the sound of guitar sound resound but also more difficult to control.
Besides, when you record a guitar in a room with a lot of furniture, the sound quality will be tighter, less resonant because the furniture absorbs the sound created from the guitar.
The key to choosing the best recording location is to use your ears to identify the sound coming from the guitar as you play.
You should try playing the guitar in different positions, listen and then choose the most suitable position to put the guitar and microphone.
2.Using the right type of microphone
The next factor you need to consider when you want to get the perfect guitar sound is to choose the right microphone type. The microphone plays an important role.
If you have good post-production preparation but your microphone is unable to capture clear and accurate sound, then the recording will not be as you expect.
In theory, the microphone plays the role of sound into energy signals. Different types of microphones will have different sound conversion mechanisms.
Current types of microphones are very diverse, but the most popular is Condenser and Dynamic Microphones.
Specifically, it is common to use condenser microphones in studios to capture sound with great detail and precision. Therefore, the condenser mic will pick up and amplify sound in a subtle and precise way.
This is made possible by the use of a lightweight diaphragm (called the diaphragm) which is suspended by a fixed plate.
The sound pressure will act on the diaphragm and make it move, thus creating an electrical output for the microphone.
Dynamic mics are the best choice when you want to record loud sounds.
Unlike a condenser microphone, the dynamic microphone uses a coil inside the microphone to amplify the signal captured by the driver, thus producing a much lower output than the condenser microphone.
This will help record sound loud and strong without noise. Dynamic microphones have the advantage of ruggedness and high performance.
Therefore, you will not need regular mic maintenance as when using other types of mics. This type of mic is able to extend the output level, often high enough to smoothly meet most mic inputs with an ideal signal-noise ratio.
3.Recording In Mono or Recording In Stereo
Specifically, recording in mono means you only use one mic to record while recording with stereo means you record with two mics.
We will help you quickly distinguish these two types of recording and you will choose for yourself the appropriate type of recording.
Record in mono:
– Simple and fast to set up the device while recording
– No need to go through complicated recording stages
– To thicken the arrangement, you can record each part of the guitar.
Record in stereo:
– Help you record the width and depth of the sound after obtaining the monophonic recording.
– The device will be more complicated.
– Because the acoustic guitar is a major feature of the song, sparse arrangements are necessary.
Here are some common mistakes to avoid in placing a microphone to record an acoustic guitar:
Put the microphone in front of the audio hole.
Sound holes are where the sound comes from, but this position is where low frequencies of sound are produced.
So if you put the mic in front of the soundhole, you’ll get a ‘boomy’ sounding guitar which won’t sound vibrant and will be hard to mix.
Put the microphone too close to the guitar
Normally people will think that the microphone should be placed as close to the guitar as possible, but this is a misunderstanding.
If you put the microphone too close to the guitar, the sound you get will only be the interwoven sound effects, the noise and the guitar’s natural interactions with the room will be mixed in other noises.
Therefore, it is best to place the microphone about 6 inches away from the guitar and continue to adjust further if not appropriate.
Remember, if you want to capture the sound of a guitar professionally, you need to consider the context of the instrument in the song.
If you want to highlight a particular piece of sound, you should apply the stereo recording technique.
If you want to thicken an arrangement, the mono mic technique is what you’re looking for.
