Dynamic processing is a crucial aspect of electronic music production. It involves manipulating the volume levels of audio signals to achieve desired effects. and limiting are key tools used to control , enhance punch, and tame peaks in a mix.
Advanced techniques like , , and multi-band compression offer more nuanced control over dynamics. These methods allow producers to create balanced mixes, maintain energy levels, and achieve cohesion across different elements in a track.

Digital Audio Dynamic Range - PEDAL POINT SOUND View original
Compression reduces dynamic range by attenuating signals above a set level at which compression begins
determines the amount of compression applied once the signal exceeds the threshold, with higher ratios resulting in more aggressive compression (4:1, 8:1)
time specifies how quickly the reacts to the signal exceeding the threshold (1 ms, 50 ms)
time defines how long the compressor takes to return to normal gain after the signal falls below the threshold (100 ms, 500 ms)
Makeup gain amplifies the compressed signal to compensate for the overall volume reduction caused by compression
Limiting is a form of compression with a high ratio (typically 10:1 or higher) that prevents the signal from exceeding a set ceiling or maximum output level
Brick-wall limiting employs an extreme ratio (20:1 or higher) to strictly enforce the ceiling and prevent any peaks from passing through
Dynamic range control in electronic music
Controlling dynamic range involves reducing volume differences between loud and quiet parts of a signal to maintain consistent perceived loudness throughout a track or mix
Enhancing punch is achieved by using compression with fast attack and release times to emphasize transients, particularly on individual drum elements like kick and snare
Taming peaks employs limiting to prevent clipping and maintain , while moderate compression with a higher threshold can control occasional peaks without over-compressing the entire signal
Advanced Dynamic Processing Techniques
Compression for balanced mixes
Parallel compression blends a compressed signal with the original uncompressed signal, maintaining dynamic range while adding body and density to the mix
Sidechain compression uses an external signal (kick drum) to trigger compression on another element (bass), creating space for the triggering element by ducking the compressed signal when the trigger is present
Multi-band compression splits the signal into multiple frequency bands (low, mid, high) and compresses each band independently, allowing for targeted dynamic control in specific frequency ranges
Master and limiting apply gentle processing to the entire mix, gluing elements together and increasing overall perceived loudness without sacrificing dynamics
Impact of dynamic processing
Evaluating compression effects involves assessing how compression settings influence the character and timbre of individual elements while considering the trade-off between dynamic control and preserving the natural sound
Balancing dynamics and energy requires using compression and limiting to maintain consistent energy levels throughout the arrangement while avoiding over-compression, which can lead to a lifeless and fatiguing sound
Monitoring and adjusting involve regularly comparing processed and unprocessed signals to gauge the impact of dynamic processing and making iterative adjustments to achieve the desired balance and cohesion in the mix
