• Layering multiple sounds to create complex, rich effects
• Applying effects processors (reverb, delay, distortion) to enhance or alter the original sound

Timing and synchronization

• Using SMPTE timecode to lock effects to video playback or automated set pieces
• Programming precise delay times to account for sound travel in large theater spaces
• Implementing follow cues in digital playback systems for seamless sequencing of effects
• Rehearsing with actors to fine-tune the timing of manually triggered effects

Placement and directionality

• Strategic placement and directionality of spot effects significantly impact the audience's perception and immersion in the theatrical experience
• Sound designers must consider the acoustic properties of the theater space when determining effect placement
• Proper placement enhances the illusion of sound sources originating from specific locations on stage

Speaker positioning

• Proscenium speakers for general effect reinforcement
• On-stage speakers hidden within set pieces for localized effects
• Surround speakers for ambient effects or to create a sense of movement
• Subwoofers for low-frequency enhancement of effects (explosions, thunder)

Sound localization techniques

• Amplitude panning between multiple speakers to create phantom sound sources
• Time-delay techniques to simulate distance and depth on stage
• Frequency-dependent routing to enhance the realism of effect placement
• Use of directional speakers (parabolic, column arrays) for precise sound focusing

Integration with other sound elements

• Spot effects must be carefully integrated with other audio components to create a cohesive soundscape for the production
• Sound designers work closely with composers and dialogue coaches to ensure all audio elements support the overall narrative
• Proper integration enhances the audience's understanding and emotional connection to the story

Balancing with background audio

• Adjusting effect levels to sit appropriately within the overall mix
• Using sidechain compression to duck background music during important spot effects
• Applying frequency-specific EQ to carve out space for effects within dense soundscapes
• Implementing dynamic range control to maintain clarity of effects in varying acoustic environments

Coordination with dialogue

• Timing effects to enhance rather than obscure important lines
• Using spot effects to punctuate or emphasize specific words or phrases
• Adjusting the frequency content of effects to avoid masking speech intelligibility
• Implementing ducking or gating techniques to automatically lower effect volume during dialogue

Cueing and playback

• Effective cueing and playback of spot effects are crucial for maintaining the flow and timing of a theatrical performance
• Sound designers must choose appropriate triggering methods based on the complexity of the show and available resources
• Reliable playback systems ensure consistent delivery of effects across multiple performances
