Quantization
Definition
The process of aligning recorded audio or MIDI events to a defined rhythmic grid within a DAW. Used to correct timing inaccuracies in performances. The degree of quantization applied ranges from full (hard snap to grid) to partial (slight nudge toward the grid while preserving feel).
In Simple Terms
Snapping notes to a rhythmic grid in your DAW to fix timing. Full quantization makes it perfectly robotic; partial quantization tightens it up while keeping the human feel. Most modern music uses some amount of quantization.
In Practice
A drum machine MIDI pattern is fully quantized to a 16th-note grid for a mechanical, precise feel. A live jazz piano performance is left unquantized entirely to preserve the natural rhythmic expression of the player.
Common Confusion
Heavy quantization removes the subtle timing variations that give a performance its groove and humanity. Many engineers prefer partial quantization or swing quantization to preserve feel while correcting obvious errors.
