Study Notes

The Studio Environment

Audio production can happen in various environments, from field recording with simple setups to complex studio configurations.
A production studio is a formal setting equipped with tools for creating finished audio content, like commercials and PSAs.
Studios can vary in name (e.g., "Production 1," "Prod. B," "PDX") and may include multiple spaces for different purposes.
Modern studios could be compact setups with computer and audio equipment, or larger configurations with extensive audio consoles.

The Audio Chain

The audio chain outlines the interconnected path of audio equipment from sources, like microphones, to output systems for recording or broadcasting.
Signal processing can occur throughout this chain and often involves equipment like mixers, equalizers, and multitrack recorders.
Equipment complexity varies with studio size and budget, affecting how sound is manipulated and recorded.
Monitoring is usually done through headphones or studio speakers.

Studio Layout

Many studios adopt a U-shaped layout for accessibility and operators’ efficiency, placing all necessary controls within easy reach.
The combo operation model has announcers also serving as equipment operators, merging roles in a single working space.
Ergonomics is a key consideration, with sit-down versus stand-up designs affecting operator comfort and efficiency.
Adjustable-height furniture enhances accessibility and comfort, promoting an energetic working environment.

Production Studio Furniture

Studio furniture is essential for housing equipment and should be tailored to the studio's specifications for optimal function.
Custom-built furniture can be expensive but offers precise dimensions, while modular systems provide flexibility for rearrangement.
Modern studios integrate computer equipment alongside traditional audio equipment to streamline production.
Proper placement of monitors and keyboards is crucial to prevent strain and ensure ergonomic efficiency.

Studio Sound Considerations

The studio's physical characteristics significantly influence sound quality, with factors like isolation, noise control, and acoustics being vital.
Sound behaviors include reflection, absorption, penetration, and diffusion, impacting how sound is produced and recorded.
Direct sound reaches the microphone quickly, while reflected sound lags behind, influencing the overall audio quality.
Managing sound characteristics involves balancing absorption (which quiets sound) and diffusion (which disperses sound) for clearer production.

Studio Construction Materials

Effective sound isolation prevents unwanted external noise from entering and minimizes internal sound leakage.
Soundproofing measures include heavy-duty doors, double-glazed windows, and acoustically treated walls to control sound reflection and absorption.
Acoustic panels and specialized materials help maintain audio integrity by absorbing unwanted reverberations.
Carpeting and less-effective treatments like egg cartons have historically been used, though modern solutions employ advanced designs for acoustical performance.### Sound Absorption Coefficient
Sound absorption can vary significantly between materials, with coefficients ranging from 0.00 (no absorption) to 1.00 (complete absorption).
Hard surfaces like plaster walls (0.04) and glass windows (0.12) have low absorption compared to materials like Sonex foam (0.81) and window curtains (0.75).
Soundproofing aims to create a "dead" sound, minimizing reverb and echo.

Studio Design Considerations

Studio design should minimize reflections to avoid harsh sounds; non-parallel walls help combat standing waves and excessive echo.
Standing waves occur when sound waves reflect between parallel surfaces, leading to uneven audio.
Studio dimensions should avoid cubic shapes to reduce frequency boosting and cancellation effects.

Studio Aesthetics

Aesthetics in studio design improve user experience; avoid fluorescent lighting due to hum and glare.
Lighting should be adjustable and comfortable; ergonomic furniture prevents noise from movement during recording.
Decor elements like paintings and posters enhance the studio atmosphere.

Static Electricity Management

Heavy carpeting in studios can increase static electricity, potentially disrupting equipment.
Anti-static measures involve using sprays, fabric softeners, or conductive laminates to minimize static buildup.

On-Air/Recording Indicators

On-air lights indicate live microphones; when lit, studio entry should be restricted and silence observed.

Communication in Studios

Hand signals, though less common, are crucial for nonverbal communication during recordings, especially when microphones are live.
Common signals include "standby," "cue talent," and timing cues for program lengths.

Noise and Distortion

Noise is any unwanted sound added during production; a good signal-to-noise ratio is typically above 60 dB for analog and 98 dB for digital equipment.
Distortion occurs when sounds are inaccurately reproduced—common causes include overdriven signals which produce muddy audio.

Sound and Audio Signals

Sound signals result from natural sound (e.g., a voice), while audio signals arise from electronic manipulation (e.g., recordings).
Understanding the difference helps navigate audio production processes effectively.

Sound Basics

Sound is generated through vibrations and transmitted through mediums (usually air); sound waves consist of compressions and rarefactions.
The sine wave is used to represent sound waves, showcasing their amplitude and frequency characteristics.

Sound Waveforms

Frequencies, harmonics, and overtones combine to define timbre; sound waves can interact in-phase (amplifying) or out-of-phase (cancelling).
Complex waveforms are a blend of various sound wave interactions, resulting in unique audio characteristics.

Sound Envelope

The envelope of sound describes its volume changes over time and includes stages: attack, decay, sustain, and release.
Manipulating sound envelopes is essential in postproduction to create desired audio effects.

Frequency Response

Frequency response refers to the range of sound frequencies that audio equipment can reproduce effectively, impacting overall audio quality.### Human Ear Frequency Range
The human ear typically hears frequencies from 20 Hz to 20,000 Hz.
Most individuals have a slightly limited range within this spectrum.

Audio Equipment Frequency Response

Quality of audio equipment measured by frequency response.
Monitor speakers can have a response of 40 Hz to 18 kHz, accurately reproducing those frequencies.
Inexpensive microphones may only respond between 80 Hz and 13 kHz, inadequate for higher frequencies.

Importance in Audio Recording

Human voice typically ranges from 200 Hz to 3,000 Hz, making narrower frequency microphones suitable for speech.
For musical recordings covering a wider range, better microphones with an extensive frequency response are necessary.

Frequency Response Curve

Frequency response curves illustrate how well equipment picks up different frequencies.
Broadcast equipment ideally has a flat frequency response, although few achieve true flatness.

Audio Frequency Spectrum

Divided into three regions: bass, midrange, and treble:
- Bass: 20 to 250 Hz; provides power; imbalance leads to thin or boomy sounds.
- Midrange: 250 Hz to 4,500 Hz; adds substance and intelligibility; too little can lead to lack of presence, too much can create harshness.
- Treble: 4,500 Hz to 20,000 Hz; gives brilliance and sharpness; imbalance results in dullness or excessive sparkle and hissing.

Musical Intervals and Octaves

Auditory perception varies in octaves, which involve doubling or halving frequencies.
Example of octave progression: 110 Hz to 220 Hz to 440 Hz and so on.

Equal Loudness Principle

Perception of loudness is influenced by pitch; midrange frequencies are heard better than high or low frequencies.
Audio production often includes equalization to balance levels across frequencies.

Audio Production Environment

Lack of control over studio construction can be offset with sound treatment techniques.
Familiarity with the audio studio grows with practice and learning equipment operation techniques.
