What is the golden rule of sound recording?

In the fields of audiology, sound recording, and engineering audio design, a commonly held adage or golden rule is that the frequency response should be as flat or as “smooth” as possible. This has also been a mainstay in our clinical practice, as well.

What is the Golden ratio in audio?

The Golden Ratio:

The ratio, named phi, of height to width to length of a room to achieve optimal sound in a room is approximately the width 1.6 times the height and the length 2.6 times the height, and was named for the Greek sculptor Phidias.

What is the principle of sound recording?

sound recording, transcription of vibrations in air that are perceptible as sound onto a storage medium, such as a phonograph disc. In sound reproduction the process is reversed so that the variations stored on the medium are converted back into sound waves.

What are the 3 requirements of sound?

What are the four principles of sound?

Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration, or in musical terms, pitch, dynamic, timbre (tone color), and duration.

The Golden Rule of Sharing a Practice Space

What is a good sound to noise ratio?

It is generally considered that a good signal to noise ratio is 60 dB or more for a phono turntable, 90 dB or more for an amplifier or CD player, 100 dB or more for a preamp.

Why do artists use the golden ratio?

Some artists and architects believe that the golden ratio makes the most beautiful shapes. As a result the ratio can be found in many famous buildings and artworks, such as those by Leonardo da Vinci.

What is the golden ratio in simple terms?

What Is the Golden Ratio? The golden ratio or golden mean, represented by the Greek letter phi (ϕ), is an irrational number that approximately equals 1.618. The golden ratio results when the ratio of two numbers is the same as the ratio of their sum to the larger of the two numbers.

Why is the golden ratio important to music?

The golden ratio is used as the interval between carrier and modulator, such that the resulting timbre is an inharmonic cloud of golden-ratio-related partials. To get a sense of what the golden ratio may sound like as a musical interval, start from here and let the sounds slowly work their way into your brain.

What is the golden ratio and why is it important?

The golden ratio, approximately between 1 to 1.618, is an extremely important number to mathematicians. But when it comes to art, artists use this golden ratio because it is aesthetically pleasing. The golden ratio can be used in art and design to achieve beauty, balance, and harmony.

What ratio is used in music?

In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth (for example C to G) is 3:2 ( Play (help·info)), 1.5, and may be approximated by an equal tempered perfect fifth ( Play (help·info)) which is 2^7/12 (about 1.498).

How is Fibonacci linked to music?

The very notes in the scale are based on natural harmonics created by ratios of frequencies. Ratios found in the first seven numbers of the Fibonacci series (0, 1, 1, 2, 3, 5, 8) are related to key frequencies of musical notes.

What is the acceptable noise limit?

So, sound above 80 dB is harmful to the human ear. Additional Information: The allowable noise level in India has been set by the CPCB for various areas. The acceptable maximum in industrial areas is 75 dB during the daytime and 70 dB at night.

Which frequency is best for audio?

The generally established audio frequency range is 20 Hz to 20,000 Hz, though most people can hear less than this entire range, and as they get older, the range tends to contract on both ends.

What is the maximum acceptable noise level?

The NIOSH REL for noise is 85 decibels, using the A-weighting frequency response (often written as dBA) over an 8-hour average, usually referred to as Time-Weighted Average (TWA). Exposures at or above this level are considered hazardous. OSHA sets legal limits on noise exposure in the workplace.

What ratio should I record in?

Typically if you want to watch the video on a TV or desktop display or upload it to YouTube or other video sharing platforms then you will want to record in 16:9. On the other hand, if you want to create videos for mobile devices or for some social platforms then you could look at vertical or square aspect ratios.

What is golden ratio and Fibonacci in music?

Musical frequencies are based on Fibonacci ratios

Notes in the scale of western music are based on natural harmonics that are created by ratios of frequencies. Ratios found in the first seven numbers of the Fibonacci series ( 0, 1, 1, 2, 3, 5, 8 ) are related to key frequencies of musical notes.

What type of scale is commonly used in songs?

Pentatonic (five-note) scales are used more widely than any other scale formation. In fact, Western art music is one of the few traditions in which pentatonic scales do not predominate.

What songs use the Fibonacci sequence?

Why do artists use the Fibonacci formula?

Artists recognised that the Fibonacci Spiral is an expression of an aesthetically pleasing principle – the Rule of Thirds. This is used in the composition of a picture; by balancing the features of the image by thirds, rather than strictly centring them, a more pleasing flow to the picture is achieved.

Is 432 a Fibonacci number?

Fibonacci. Fact: No. It is not. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811.

What is the best example for golden ratio?

What is the most known value of golden ratio?

golden ratio, also known as the golden section, golden mean, or divine proportion, in mathematics, the irrational number (1 + Square root of√5)/2, often denoted by the Greek letter ϕ or τ, which is approximately equal to 1.618.
