Question 1

What are audio effects plugins and which types do I need?

Accepted Answer

Audio effects plugins (VST/VST3/AU) process audio signals to shape the sound at the mixing stage. The core types every producer needs are: EQ (equalization — cutting and boosting frequencies), compressor (controlling dynamics and transients), reverb (adding space and depth), delay (echo and timing effects), saturation (harmonic warmth and character), and limiter (preventing clipping at the master bus). Most DAWs ship with decent stock effects, but third-party free plugins like TDR Nova (EQ), Kilohearts Essentials, and Valhalla Supermassive (reverb/delay) significantly expand your toolkit.

Question 2

What is the difference between mixing effects and mastering effects?

Accepted Answer

Mixing effects are applied to individual tracks or busses within a session — EQ and compression on a drum bus, reverb on a vocal send, saturation on a bass track. Mastering effects are applied to the full stereo mix at the final stage: a mastering EQ for tonal balance, multiband compression for density, stereo widening, and a transparent limiter to achieve commercial loudness. Some plugins serve both roles, but mastering-specific tools (like iZotope Ozone, Voxengo Elephant, or TDR Limiter 6) are optimized for transparency and precision on full-mix material.

Question 3

Do free effects plugins use a lot of CPU?

Accepted Answer

CPU usage varies significantly between plugins. Simple EQs and compressors are typically lightweight (1–3% CPU per instance). Convolution reverbs, physical modelling effects, and complex spectral processors can use 5–15% per instance. To keep CPU usage manageable: use sends and returns for reverb and delay (one shared instance rather than one per track), freeze CPU-heavy tracks when not editing, and increase your audio buffer size if you experience dropouts during mixing. Most free effects plugins on Plugg Supply are well-optimized and perform efficiently even on mid-range hardware.
