Audio Recording Sound Safari

Summary

This project mostly consisted of learning the effects of equipment placement when it comes to microphones. The group I was in also explored the many specifics with the types of sound with the particular mic we were using.

Tools Used –
1) Audio deck for recording
2) Shure SM58
3) Smartphone for imaging placement
4) Drums
5) Guitar

Audio Terms and Definitions

Sound Wave
- A vibrational disturbance that involves the mechanical motion of molecules transmitting energy from one place to another.
Compression
- Reducing a signal’s output level in relation to its input level to reduce dynamic range.
Frequency
- The # of times per second that a sound source vibrates, is expressed in hertz (Hz).
Hertz
- Unit of measurement of frequency; numerically equal to cycles per second (cps).
Infrasonic
- The range below the frequencies is audible to human hearing.
Ultrasonic
- The range above the frequencies of human hearing.
Pitch
- The subjective perception of frequency – the highness or lowness of a sound.
Fundamental
- The lowest frequency a sound source can produce. In other words, it is also called the first harmonic or primary frequency which is the lowest, or basic, pitch of a musical instrument.
Sound Frequency Spectrum
- The range of frequencies audible to human hearing: about 20 to 20,000 Hz.
Octave
- The interval between the two frequencies that have a tonal ratio of 2:1.
Bass
- The low range of the audible frequency spectrum; is usually from 20 to 320 Hz.
Midrange
- The part of the frequency spectrum to which humans are most sensitive; is the frequencies between roughly 320 Hz and 2,560 Hz.
Treble
- The frequency range between roughly 5,120 Hz and 20,000 Hz, the highest two octaves audible to human hearing in the sound frequency spectrum.
Equalization
- A signal-processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system.
Amplitude
- The magnitude of a sound wave or an electric signal is measured in decibels.
Decibel (dB)
- A relative and dimensionless unit to measure the ratio of two quantities.
Wavelength
- Distance between two peaks of a wave
Velocity
- Speed in a given direction
Harmonic
- Is a multiple of the fundamental frequency
Phase
- Factor in the interaction of one wave with another, either acoustically or electronically

What I Learned & Problems I Solved

A few things I learned throughout this entire project would be the significance of mic placement. Being in a very spacious room with a Shure SM58 often created very distant audio while having the mic too low also created that same feeling.
