#### 4.5.4.4 Sound Configuration

The following options can be used to configure the sound modules. The default values are stored in `‘CS/data/config/sound.cfg’`.

#### General Sound Configuration

These options apply to all sound renderers:

`Sound.Volume = [0..1]`

  Set the global volume. A value of 0 means silence, 1 means as loud as possible. Default is 1.

#### Software Sound Configuration

These options only apply to the software sound renderer:

`Sound.Software.Frequency = <frequency>`

  This sets the output frequency. Possible values depend on your system and sound card, but divisors of 44100 (e.g. 22050 or 11025) usually work. Default is 44100 (optimal).

`Sound.Software.16Bits = <yes/no>`

  Enables 16 bit sound output. Default is yes.

`Sound.Software.Stereo = <yes/no>`

  Enables stereo sound output. Default is yes.

#### Wave-Out Configuration

These options only apply to the Wave-Out sound driver under Windows:

`Sound.WaveOut.Refresh = <rate>`

  Sets the refresh rate of the sound output as a per-second rate. The lower this rate, the more time passes between your application starting to play a sound and the sound actually being audible. Because the Wave-Out driver uses a triple buffering system, this delay is 2 to 3 seconds divided by the refresh rate. So you should set a rate of at least 10 to prevent serious delays. Default is 5.
