Non-destructive sample editing in REAPER

Step-by-step

1. Right-click the audio item and navigate to Take > Take envelope > Take sample edits
2. Zoom in until the mouse cursor changes to a pencil shape over sample points
3. Click and drag individual sample points to change their values
4. Hold Option (Mac) or Alt (Windows) while clicking a point to return it to its original position
5. Hold Alt + Shift to bring a sample point to the center line to mute it
6. Right-click a point or the line to access the context menu for batch actions like scaling or clearing edits

Options

• Delete sample edits in a specific time selection
• Set sample values to a straight line in a time selection
• Scale sample values in a time selection to expand or compress edits around the center point
• Clear edits for a single channel or all channels
• Customize mouse modifiers under the 'Sample edit' context in settings

Watch out for

• Sample points are only editable when you are zoomed in sufficiently
• Edits are independent for left and right channels in multi-channel files
• To open the short menu, you must right-click on the line or a point, not the empty space between them

Tips

• Use this feature to fix clicks and pops by evening out the very first sample of a recording
• Use it to take the 'spiky edge' off of harsh audio glitches
• Use the 'set to zero' function in a time selection to effectively mute a specific tiny area

“Pretty cool stuff.”
