Jazz recordings were never quantized, but with today's technology you can do much more with quantized music.
Quantization started with the invention of
MIDI, an electronic music protocol invented in the 80's.
MIDI have evolved to a point where it's possible to
- Change audio peaks to midi notes (via setting a waveform peak threshold)
- Quantize audio/midi to any note rate (1/2 to 1/128th...etc)
- Reference predefined grooves that have a
customized quantization(as seen in Ableton's Groove feature https://www.ableton.com/en/manual/using-grooves/
- Changing each pitch of a sung vocal (Auto-tune)
- Set the amount of quantization applied (Between 100% "wet" and 100% "dry")
"Modern" Jazz Recordings to have quantized drums, I highly doubt it as that goes against the art form, which is based on human expression. You mostly find quantization in popular music, although it could be possible to find it in Jazz, especially with creative use. As a drummer myself,
Jazz Drummers strive to be human metronomes. When playing to a
"Click Track" they practice every rhythm against these three basic "feels". You might also hear this referred to as
"Playing in the Pocket"...
Playing "on the beat" where the "click" is masked by a rhythmic note to where you can't even hear a click! This is usually what is meant by "playing on the grid"
Playing behind the beat where you play a groove slightly behind the click consistently to achieve a laid back feel
Playing ahead of the beat where you play a groove ahead of the beat, mostly in dance or upbeat feels
Every good Jazz drummer is a master of these concepts and takes pride in developing their own feel behind the drums...
A Modern Jazz Drummer I'd recommend checking out is
Chris "Daddy" Dave. He's recorded a lot of
Robert Glasper's records, and also recorded a few songs on
Adele's album. Watching him play live, you become captivated at his ability to play ultra fast, complex rhythms and then come back in on one into a simple groove, still keeping the same tempo and feel or
smoothly changing the tempo into something else. This type of human control with varying tempo is something that is not as easily achieved with quantization, although the article
Torley pointed out is interesting...
Overall, even though you could easily apply any number of quantize techniques on a recorded track, I don't really see it happening to Jazz, although it could be possible if done creatively. It also depends on the producer, label, and engineer. However, you will find
Quantization mostly on popular songs.
