Hints and tips

Here are a few hints and tips for using REW

• REW's mdat files can be opened by double-clicking on them or by dragging them onto the REW window
• Impulse response files in .wav or .aiff format can be imported by dragging them onto the REW window
• The measurement list can be navigated by using Alt+UP and Alt+DOWN to go up and down the list, or any of the first 9 measurements can be selected directly using ALT+1 or 2 or 3…9
• A measurement can be moved up or down in the list by selecting it then pressing and holding the left mouse button and dragging the measurement up or down to where you want it
• The graphs can be navigated by using Ctrl+RIGHT and Ctrl+LEFT to go to the next or previous graph, or Ctrl+1 or 2 or 3…9 will go to the 1st, 2nd etc graph
• Moving the cursor over the name of a trace in the graph legend will highlight that trace in the graph
• If a measurement's name is shown in blue on the measurements panel it means it has been modified since it was loaded
• Use Ctrl+Shift+3 to apply 1/3rd octave smoothing, repeat to remove the smoothing. Ctrl+Shift+X applies variable smoothing
• If you accidentally delete a measurement use the Restore Last Removed entry in the file menu to recover it
• You can clear or select all traces in an overlay graph by right clicking in the legend area
• The graph can be moved by pressing the right mouse button and dragging
• The mouse wheel can be used to zoom in or out on a graph
• Variable zoom is available by pressing and holding the right mouse button, then while the right button is down pressing the left button, then drag the mouse
• You can measure between points on a graph by holding down the Ctrl key, pressing the right mouse button and dragging the mouse
• There are also keyboard graph controls: the cursor keys move the graph cursors; shift+cursor keys move the graph; x and shift+x zoom out/in on the x axis, y and shift+y zoom out/in on the y axis
• There are keyboard shortcuts for most actions, listed in the shortcuts section
• The space bar can be used to press the currently highlighted button instead of the mouse
• To make more space for the graph (e.g. at lower screen resolutions) use the expand/collapse button above the measurement panels to reduce the width they take up and turn off the graph scroll bars using the button above the graph. You can also remove the labels under the toolbar and graph buttons by unchecking boxes in the View preferences to make more vertical space. You can remove the toolbar by unchecking the Show toolbar box in the View preferences (everything in the toolbar has a corresponding menu entry and a keyboard shortcut).
