# Mixer Toolbar

### From Audacity Manual

The Mixer Toolbar is where you control the playback and recording volumes in conjunction with the Meter Toolbar.

  Output Volume Slider: Sets the playback volume.

  Input Volume Slider: Sets the recording volume.

## Output Slider

This is the left-hand slider that lets you control the volume at which you listen to the mix of your project. This is a "monitor" control, and does not affect the level of your mix, so will not help if your mix is clipped. It does not affect the levels indicated by the playback meters which do reflect the level of the mix.

Should your output 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 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.

## Input Slider

If the Input 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 sound card control panel. To locate the system mixer see the help on our Wiki for Windows, Mac OS X or Linux.

This right-hand slider controls the level of the currently selected "Input 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 sound card may have. The Input Slider should then control that input.

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

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

## Precise Volume Adjustment

Double-clicking on the input or output volume slider will bring up the Input Volume or Output 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.
