With every turn in the knob on a mixer or mastering tool is a certain application of acoustics with the recording. If you possibly could grasp the acoustics of recording and the way it works with the development of your distinct sound, you will also have more capabilities in recording and the way you are able to portray the audio sounds that you are creating.
Acoustics begins with the vibration of air, or in some instances, an electronic device. With natural acoustics, air moves through a certain compartment, including an instrument or the voice. The greater the vibration of the air moves, the harder sound it is able to create for your instrument. This is what leads to the sound waves, for re-creations of the vibration of air which is moving through the space that it is in.
The vibration of air is exactly what causes various acoustics to respond in the given space. It is also the simple concept of air vibration which leads to specific ideals about how to set a recording studio in order to take in the right sounds to record. Working out control acoustics becomes the basis for starting a recording studio as well as the main concept to managing sounds as they are recorded.
When a sound is made through an instrument, it has a variety of levels of air that it hits and causes to vibrate. At one level, we hear this as being a note that is played from the sound. However, the acoustics will take on different capacities in producing different sounds which are not heard.
The first sound that is produced comes from the environment the location where the sound is played. If the room is larger, has further ceilings and it is spacious, the sound will bounce from the walls. This will cause the sound to go faster, become louder also to resonate throughout the area. For recording, this is the reason the walls are deadened and smaller spaces are created. If there is the echo effect within the song, it can begin to appear to be the beats are off.
One way in which acoustics change the sound is thru resonance. This is when the vibration of the sound is heard, even though the note is no longer being sung or played. This resonance can easily still move as long as the vibration of air will continue to hit the particular area. Usually, resonance will be a filtering off of the initial sound because the vibration of air is constantly on the slow down. In recording, this resonance is additionally muffled through the sound proof rooms in order to make a clearer sound.
The last part of acoustic sounds is the concept of overtones. Even though we only hear one note that is being played or sung, it’s not the only note that is in the air. Acoustics produce a vibration of sound waves that still resonate and vibrate at different levels. These will likely be pitches that are created over the original pitch, with specific spacings in the pitch. While they are not heard, they still create an impact on the ear with the sound vibration that moves over the air. This also makes a difference in recording, because overtones can create a different effect and can be recorded as a wave file. This could cause differences in peaks along with basic sounds that are heard in the piece.
With the understanding of these acoustic ideas is also the ability to control it within the recording studio. Each one of these areas are ‘sound proofed’ at certain levels. This can be to allow the audio to move into the recording area as being a pure wave file, that can then stop the acoustic sounds from muffling, echoing or changing the sound that’s intended to be heard in the recording.
When defining acoustics and recording, there are many of perspectives to consider that relate to sound waves and how they work. By understanding these perspectives, you may create a recording area that is more conducive to muffle certain acoustics also to let others resonate with the air.
