## Abstract : Tone

This class is included as part of the file Tone.tz.
To use this class in a simulation, include the line "@use Tone."

### Class description:

> A Tone is an object which plays a constant tone. You can set the volume, frequency and left-right balance of the tone. Creating the object will automatically start playing the tone. Deleting the object will cause the tone to stop playing.

> A tone can also be effectively stopped by setting its volume to 0.

### Class methods:

> - set-balance
> - set-frequency
> - set-volume

`set-balance to newBalance (double)`

> Sets the left/right balance of the sinewave to newBalance, a value between 0 and 1. .5 is perfectly balanced, while 1.0 plays the tone completely on the right channel and 0.0 plays the tone entirely on the left channel.

`set-frequency to newFrequency (double)`

> Sets the frequency of the tone to newFrequency.

`set-volume to newVolume (double)`

> Sets the volume of the tone to newVolume. Volume is specified on a scale from 0.0 to 1.0.
