Positioning a microphone close to the soundhole can yield a full-bodied recording. Nonetheless, this method should be dealt with with care. The soundhole is the supply of the guitar’s bass frequencies, and putting the mic too shut could end in a very boomy recording. A very good strategy is to take care of a distance of round 12 to 18 inches, permitting the mic to seize each the direct sound from the strings and the resonance of the physique with out overwhelming the combo.
2. The ‘twelfth Fret’ Technique
A preferred methodology amongst recording engineers is to put the microphone across the twelfth fret. This place balances the brightness from the strings with the heat from the physique. Right here, the mic is ideally angled barely in the direction of the bridge. This system helps to seize articulation and element whereas retaining the pure physique resonance. Experimenting with the angle and distance is essential to keep away from harsh excessive frequencies or muddiness within the low finish.
3. Room Miking
Including a room mic can deliver a way of area and atmosphere to your recording. Sometimes, a secondary microphone positioned just a few toes away from the guitar can seize the room’s acoustics. When blended with the close-miked sign, this methodology affords depth and context, making the guitar sound extra pure and full of life. The bottom line is to discover a stability that enriches the first sound with out overwhelming it with reverb.
4. Stereo Methods
For an excellent richer recording, stereo strategies comparable to XY, ORTF, or spaced pair setups will be utilised. These strategies seize the stereo picture of the acoustic guitar, offering a extra immersive listening expertise. The XY approach, the place two cardioid microphones are positioned at a 90-degree angle, is especially efficient in capturing the guitar’s spatial traits whereas sustaining section coherence.
Greatest Gear for Recording Acoustic Guitar
The standard of your recording gear considerably influences the ultimate sound. Listed here are some important items of apparatus that may aid you obtain an expert sound.

Don’t underestimate the significance of high quality cables and stands. Poor cables can introduce undesirable noise, whereas steady mic stands guarantee constant placement all through the recording session. It’s advisable to spend money on sturdy, high-quality equipment to keep away from any points throughout recording.
4. Monitoring Tools
Correct monitoring is essential. Studio displays or high-quality headphones help you hear the true sound of the recorded acoustic guitar. This instant suggestions is significant for making changes to mic placement and recording settings on the fly.
Optimising Your Recording Setting
Even with top-notch gear, the recording surroundings performs a crucial position within the remaining sound. An acoustically handled room minimises undesirable reflections and background noise. Listed here are just a few tricks to optimise your recording area:
- Acoustic Panels and Bass Traps: Use these to dampen harsh reflections and cut back low-frequency buildup. This creates a cleaner sound that captures the pure qualities of the guitar.
- Isolation Methods: Should you’re recording in a less-than-ideal area, take into account moveable isolation cubicles or panels that may be positioned across the recording space to cut back ambient noise.

1. Equalisation (EQ)
EQ is the inspiration of any post-processing chain. When recording an acoustic guitar, it’s frequent to make use of EQ to sculpt the tonal stability. For example:
- Low-end changes: In case your recording sounds a bit too boomy, use a high-pass filter to softly roll off frequencies beneath 80 Hz. This helps to scrub up any pointless rumble.
- Mid-range readability: Enhancing the mid frequencies can deliver ahead the articulation of the strings and the pure sound of the instrument.
- Excessive-end sparkle: A delicate enhance within the excessive frequencies can add readability and presence, although care should be taken to keep away from harshness.
2. Compression
Compression might help in smoothing out the dynamic vary of an acoustic guitar. The bottom line is to make use of it subtly. A delicate compressor setting may even out the efficiency with out sacrificing the instrument’s pure dynamics. Search for compressors that supply clear operation, such because the Common Audio 1176 or LA-2A emulations, which work nicely for acoustic devices.
3. Reverb and Atmosphere
Including reverb is likely one of the only methods to boost the spatial high quality of an acoustic recording. A plate reverb or a fastidiously chosen convolution reverb can simulate the pure atmosphere of a efficiency area. The purpose is so as to add depth with out overwhelming the pure tone of the guitar. Experiment with completely different reverb instances and settings to discover a stability that enhances the model of the music.
4. Extra Results
Whereas EQ, compression, and reverb kind the core of post-processing, different results comparable to delicate delays or modulation may also be employed so as to add texture. Nonetheless, it’s essential to make sure that these results serve the track slightly than distract from the efficiency. Much less is commonly extra in relation to results on acoustic guitar recordings.
