Mixer Toolbar - Audacity Manual

# Mixer Toolbar

### From Audacity Manual

Mixer Toolbar is where you adjust Recording Volume (the amplitude at which recordings will be made) and Playback Volume (how loud the project's audio sounds, not affecting the volume of exported audio).

  Click on the toolbar image below to see this toolbar displayed in context of the default upper tooldock layout.

  Recording Volume Slider: Sets the recording volume.

  Playback Volume Slider: Sets the playback volume.

## Recording Slider

If the recording slider does not have direct control of your sound device's input level, it will be disabled and set to maximum. You will need to set the recording levels using the input slider in the operating system mixer or in the soundcard control panel. To locate the system mixer see the help on our Wiki for Windows, Mac OS X or Linux.

This is slider with the microphone icon. It controls the level of the currently selected "Recording Device" in Device Toolbar. Inputs can also be chosen at "Recording Device" in Devices Preferences, in the operating system mixer or in any control panel that the soundcard may have. The Recording Slider should then control that input.

After selecting the required recording source, use the recording slider in conjunction with the recording level meters on the Meter Toolbars to set the correct recording level before starting to record for real.

If your input sounds distorted, lower the recording slider until no distortion can be heard, also making sure the clipping indicators on the recording meter do not light up.

## Playback Slider

This is the slider with the loudspeaker icon. It enables you control the volume at which you listen to the mix of your project. This is a purely a "monitor" control. It does not affect the level of your mix and hence does not affect the level that audio is exported at. Adjusting the playback slider will not help if your mix is clipped. The playback slider does not affect the levels indicated by the playback meters which do reflect the level of the mix.

Should your playback sound distorted, the distortion usually comes from clipping of your project's mix. You actually need to reduce the level of your tracks. It is suggested you reduce every track by the same amount using the gain sliders in the Track Control Panel.

If Windows WASAPI audio host is chosen in Device Toolbar, output is emulated (as shown in the hover tooltip for this slider). As a result, this slider will only scale the system output slider's current level up or down rather than directly manipulating that system slider.

## Precise Volume Adjustment

Double-clicking on the recording or playback volume slider will bring up the Recording Volume or Playback Volume window. Here you can make much more precise adjustments with the slider or enter a value in the text field. You can also set a keyboard shortcut to bring up either of these windows.
