Summary: “Next Level Creature Sound Design” (GDC 2017)

David Philipp (Noise Works) presents a practical framework for designing believable creature sound effects for games, focusing on how to create lifelike “one creature” vocal behavior without real-world references.

Speaker background / credibility

  • Co-founder of Noise Works Limited (audio outsourcing), London
  • Boom Library recorder and stem designer
  • Creature-sound experience in titles like:
    • Elder Scrolls Online
    • Blade & Soul
    • Arcania
    • Total War: Warhammer (led creature SFX production)

Core concept: “Believability” through character, variation, and perspective

Philipp frames great creature sound design as three “ingredients”:

  1. Character

    • How the creature acts/emotes: aggression, intelligence, stupidity, emotion
    • Vocal basis: attack, death, pain, idle behaviors

  2. Variation

    • Variation in articulations (attack/death/pain/idle)
    • Variation in sound sources and recording techniques

  3. Perspective

    • Spatial placement: indoor/outdoor, cave/close-up/far away
    • Drives how the sound “lives” in the game world

Goal: produce something that isn’t real, but is believable to the player—supporting immersion.

Pre-production: planning before recording

Philipp emphasizes pre-production as often neglected but crucial.

Key steps include:

  • Learn the creature’s origin, special skills, and characteristics
    • e.g., dragon fire breath, tail swing, “mega scream” buffs allies
  • Determine how the creature produces sound
    • whether it has a voice box / vocal mechanism / non-human anatomy
    • this affects vocal approach and what articulations are feasible
  • Confirm scale/size relationships
    • difficult to fix after recording full sets (small vs massive creatures)
  • Plan a sonic “map” (mind-map style) and timeline
    • example: planning a random dragon to a total of 42 sound effects
  • Decide on potential sources from:
    • humans
    • animals
    • non-literal recordings (objects/props)

Recording process: microphones and source strategies

Philipp argues that different microphones capture useful layers for pitching and blending.

Microphones highlighted

  1. Sanken C100K

    • Captures up to ~100 kHz (useful for pitching without losing detail)
    • Pitch-down trials: record raw then pitch down multiple octaves while retaining crispness
    • Notes:
      • omnidirectional → harder outdoors
      • stops working below ~10°C
      • workaround: wait for warmer weather / use pocket warmers + tape/rigging

  2. Sennheiser MKH series

    • Field-friendly; commonly used
    • ~half frequency response vs C100K (~50 kHz), still usable for pitching
    • Available in cardioid / supercardioid (e.g., MKH 8014), often used as MS setup

  3. Contact mics (Barcus Berry)

    • Captures dry, isolated signals (throat, objects, room elements)
    • Expensive; higher-end models provide higher fidelity vs cheaper options
    • Used as alternate “layers” that later become part of creature texture

Human recordings

  • Pros

    • Directional and can perform “on command”
    • Cheaper than animals (especially without actors)
    • Easier to record in controlled environments
    • Can request “weird” sounds from coworkers via email (example workflow)

  • Cons

    • After pitching down (2–3 octaves), humans can sound similar and messy
    • Sore throat/hoarseness limits how far performers can go

  • Best practice

    • Maintain variation through different recording techniques, not just pitch/speed changes.

Animal recordings

  • Pros

    • Some sounds are hard/impossible to reproduce convincingly with humans
    • Natural character (horses, bears, seals, vultures, etc.)

  • Cons

    • Animals often won’t vocalize on cue; field time is unpredictable
    • Uncontrolled environments create heavy cleaning/editing work
    • Costs can be high if agencies train animals for specific performances
    • Some setups can be dangerous (mating season, wildcats, stags, etc.)

  • Field tips

    • Choose quiet locations (example: UK near flight paths/motorways)
    • Record surrounding ambience first (build an archive)
    • Talk to animal handlers/trainers for “tricks” (e.g., vocalize when hungry)
    • Plan insurance / safety; boom setups accordingly

Non-literal recordings (props/objects)

Philipp calls this the most interesting and creatively challenging technique.

  • Examples

    • tire squeals, balloon scrapes, door creaks, metal scrapes, dryers on metal

  • Advice

    • “look for sounds, not props”
    • carry a recorder / notepad and capture unexpected everyday noises

  • Demonstration idea

    • Using balloon scrape layers plus a human scream can create a creature-like composite with new character.

Design phase: layering and the “homogenous creature” requirement

Creature sound design is fundamentally layer-based, but the craft is making layers behave like one creature.

Key design principles

  • Internal tonal relationship matters more than plugins

    • Pitch matching between layers is critical
    • EQ/volume offsets help balance harmonic/body resonance

  • Pitch matching example

    • Adding a new layer can disrupt tonal harmony → requires re-pitching other layers

  • Analogy

    • Like arranging music: a guitar riff and bass must be in tune.

Tooling notes: plugins used (processing support)

Examples mentioned for processing include:

  • iZotope RX / RX features
    • denoise, declip, cleaning
  • Synaptic Morph 2
    • morph spectral characteristics of one sound into another
  • Elastic Pitch
    • automating pitch over time (e.g., pitch shifts when a creature dies/falls)
  • Waves / (Magique Q mention)
    • uses EQ knobs to restore brilliance/highs after heavy pitching loss
  • Wave/other “bigness” shaping plugin
  • Dehumanizer 2
    • large parameter set, modular, automatable; integrated into Pro Tools via plugin format

Plugins support the work, but believability depends primarily on layer/source relationships.

Implementation: game integration is “50%” of success

Philipp emphasizes that even perfect audio can fail if integration is wrong.

Game audio system tips

  • Hierarchy/setup matters

    • Example: Total War: Warhammer used creature sizes: small/medium/large/extra large/huge
    • ensures big creatures stay big in-game mixing

  • Modular vs one-shot articulation

    • One-shot: attach a trigger to an animation event
    • Modular: split sounds (e.g., scream into start/middle/stop) for tighter animation synchronization

  • Perspective and distance workflow

    • Start with close-up sound layers
    • Also create distant versions (often derived from close layers by removing layers to simulate distance)
    • Blend by in-engine parameters

  • Cone attenuation / directional EQ

    • adjust lowpass/highpass based on creature facing angle and camera direction

  • Gain staging

    • large creatures should be louder than small ones
    • recommend setting initial gain offsets to make mixing easier

  • Sweetener/proximity layers

    • add extra stereo/quad “proximity” textures when creatures are very close

Takeaways / checklist style guidance

  • Pre-production is key
    • understand creature mechanics, skills, scale, and sound production method
  • Record as much source material as possible
    • build a library for variation and layering options
  • Design with the foundational trio
    • pitch matching, EQ, volume
  • Don’t rely on “the plugins”
    • they support the work, but source and layer relationships determine believability
  • Get involved in implementation
    • or coordinate tightly with implementation/engine/audio teams
  • Final goal
    • character + believability for immersion
