Study Notes

Overview of "Mixing Audio"

  • Third edition published in 2018, authored by Roey Izhaki, an experienced audio engineer and lecturer.
  • Offers comprehensive insights on the mixing process from basics to advanced techniques.
  • Includes visual aids like photos, graphs, and audio samples to enhance the learning experience.
  • Features over 2,000 audio samples and 5 multitracks on its companion website.

Key Features of the Book

  • New chapter on “Mixing and the brain,” focusing on cognitive and psychological aspects of mixing.
  • Updates reflecting the latest software changes and industry trends.
  • A valuable resource for both aspiring and professional mixing engineers.

Historical Context of Mixing

  • Mixing evolved from primitive orchestral assembly to the use of multitrack tape machines in the 1960s.
  • The introduction of equalizers, compressors, and reverbs revolutionized the mixing landscape.
  • The 1990s saw a shift to digital audio workstations (DAWs), making mixing more accessible than ever.

Technological Advances

  • The emergence of real-time audio plugins since the mid-1990s lowered barriers for project studios.
  • Modern DAWs allow for extensive audio processing capabilities, challenging professional studio advantages.
  • There are now more audio plugins available than hardware tools, with continuous improvements in quality.

Challenges in Modern Mixing

  • Despite increased accessibility, there is a disparity in expertise among many independent producers.
  • Mixing is frequently performed by individuals who juggle multiple roles outside dedicated engineering skills.
  • The book aims to guide those looking to improve their mixing skills efficiently, especially under tight time constraints.

Conceptual Understanding of Mixing

  • Mixing is not merely a technical task; it involves artistry and creativity.
  • The essence of mixing lies in crafting soundscapes, harmonizing instruments, and influencing musical perception.
  • A mix acts as a sonic portrait, conveying variations in interpretation much like different representations of a person.

Health Considerations

  • Engineers must be cautious with volume levels to prevent hearing damage; long exposure to loud sounds can lead to irreversible effects.
  • Recommendations from health authorities suggest limiting exposure to sounds above 85 dBSPL to prevent hearing loss.
  • It is crucial to maintain safe monitoring levels during the mixing process to protect hearing while ensuring audio quality.### Music and Mixing
  • Music serves as a universal passion, connecting songwriters, producers, and performers through creative expression.
  • Modern technology has transformed music accessibility, with innovations like wax cylinders, radio, tapes, CDs, and streaming services facilitating widespread consumption and production.
  • Emotional connection to music is crucial; pieces elicit mental and physical responses, influencing mood and memories.
  • Mixing involves balancing and combining multitrack material into a cohesive, emotionally resonant sonic presentation rather than simply a technical process.
  • Mixing engineers must comprehend the emotions and messages behind a song to enhance its delivery and impact.
  • The role of mixing is critical in determining an album's or track's success, with notable mixes influencing listener experience and commercial viability.
  • Different mixing styles can produce vastly different results from the same raw material, showcasing the diverse sonic visions of mixing engineers.
  • Mixing quality influences consumer preference, with higher fidelity contributing to music's appeal, notably during the transition from cassettes to CDs and digital formats.

The Art of Mixing

  • Historical context shows religious music's prevalence until the 19th century, with secular music evolving significantly thanks to influential composers like Beethoven, who emotionally engaged listeners.
  • A mix should enhance the emotional context of a song, and discussions around elements such as instrument balance and effects like reverb are essential for achieving this.
  • Noteworthy examples:
    • Butch Vig's and Andy Wallace’s contrasting mixes of Nirvana's "Smells Like Teen Spirit" highlight how artistic choices affect the reception and legacy of a track.
    • The comparison of mixes in the 10th anniversary edition of The Holy Bible by Manic Street Preachers illustrates the impact of mixing styles on artistic vision.

Understanding Mix Quality

  • Sonic quality directly affects listener experience; clear sound quality is essential, influencing preferences in playback systems.
  • Mixing can dramatically alter the perception of an album; the quality of the raw material plays a vital role in the final mix’s success.
  • Mixing engineers are responsible for crafting the final sound, balancing individual instrument qualities and overall coherence.
  • The perfect mix is subjective; varying standards exist across genres and personal preferences contribute to opinions on mix quality.

Psychoacoustics and Loudness

  • The Fletcher-Munson experiments from 1933 reveal insights into human perception of loudness across different frequencies, leading to the development of equal-loudness contours.
  • These contours illustrate how different frequencies must be adjusted in a mix for perceived loudness, highlighting the importance of psychological factors in sound quality.
  • The study indicates that the human ear is more sensitive to frequencies around 3.5 kHz, relevant for mixing decisions, as this frequency correlates with the sounds of human emotions like a baby's cry.### Equal-Loudness Contours
  • Sensitivity to mid-frequencies is higher than lows and highs; this varies with playback levels.
  • Louder levels equalize frequency perception, making it crucial for mixing.
  • The relationship between loudness and perception leads to "louder is better" in music enjoyment.

Mixing Strategies

  • Mixing involves achieving a balanced sound across various loudness levels.
  • Softer levels reduce perception of highs and lows; ensure instrument frequency balance for consistency.
  • Mixing should adapt for expected playback volumes (e.g., dance music vs. ambient music).

Importance of Frequencies

  • Mids play a pivotal role for a balanced mix, as they are less affected by loudness variations.
  • Highs and lows should complement mids to maintain musical integrity at different volumes.

Room Reflection and Spatial Perception

  • At low volumes, listeners hear more direct sound, whereas louder volumes introduce room reflections, creating a surround effect.
  • Sound image perception changes with volume; a clearer image expands when music is played louder.

Masking Effects

  • Louder sounds can mask quieter ones; the frequency overlap of instruments affects their audibility.
  • Percussive and sustained instruments interact differently in the mix; percussive sounds are transient, while sustained sounds occupy space over time.

Instrument Importance and Context

  • Each instrument's importance varies by genre; e.g., vocals are crucial in pop, while rhythm is essential in hip-hop.
  • Use of space is critical in mixing; overtones and frequency range of sustained instruments can mask percussive sounds.

Natural vs. Artificial Sound

  • The pursuit of a “natural” sound contrasts with artistic choices for more extreme, creative effects.
  • Natural mixes reflect realistic sound stages, while artificial mixes may employ compression and reverb to enhance appeal.

Mixing Technique Development

  • Learning to mix is comparable to language acquisition; mastering tools takes practice and experience.
  • World-class mixing engineers thrive through extensive skill development and a keen understanding of sound manipulation.

Mixing Process and Vision

  • The mixing process involves three steps: defining vision, evaluating sound, and taking action.
  • Effective mixing requires a clear vision of the desired sound (e.g., powerful, clean) and the selection of appropriate processing tools.
  • Mixing techniques should enhance rather than ignore the intended auditory experience, balancing artistry with technical skill.
