About

Audio quantization is aligning the beats in an audio-item to a grid or to a predefined groove.
In Reaper this is actually item-quantization, as you can apply it to midi or audio-items. Note however, regarding midi you'd normally use midi notes quantization.
In other DAWs audio quantization are named e.g. Elastic Audio, Audio Quantize, Beat Detective and Time Warp.

Native solution

Natively Reaper has rather poorly implemented audio quantization functionality. However when used in conjunction with the recommended tools below, you'll get a fully functional way of doing this.

Dynamic Split

How to use? See: Dynamic split

Quantize

You can quantize items with the action:
"Item: Quantize item positions to grid..."

Recommended tools

Fingers Groove Tool

See: Fingers Groove Tool

AW - Fill gaps between selected items

See: AW - Fill gaps

Recommended workflow

  1. Select the audio-clip you wan't to apply changes to
  2. Use Dynamic split to split the clip at the beats.
  3. Quantize, either..
    1. Use Quantize items to grid, or
    2. Use Fingers Groove Tool
  4. Use AW - Fill gaps to stretch and smooth out crossovers
