# Components - Math

> Mathematical components such as **addition, subtraction, multiplication, squaring,** and **square root** are fundamental operations used to manipulate audio signals and perform various processing tasks.

For example, when mixing different audio tracks (e.g., vocals and instruments), the individual signals are summed together to create a single output signal. |

| #### Substract | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image(107).png) | **Differencing Signals**: Subtraction is used to find the difference between two signals. This can be useful in noise reduction techniques where the unwanted noise is subtracted from the original audio signal. |
| #### Multiply | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image(108).png) | **Amplitude Scaling**: Multiplication is used to adjust the amplitude of a signal. For instance, multiplying a signal by a coefficient less than one reduces its volume, while a coefficient greater than one increases it. |
| #### Square | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image(109).png) | **Energy Calculation**: Squaring the amplitude of a signal is often used to calculate the signal's energy. This is particularly useful in applications like audio analysis and feature extraction. |
| #### Square Root | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image(110).png) | **Normalization**: It can also be used in normalization processes where the amplitude of a signal is adjusted based on its RMS value, ensuring that the audio levels are consistent. |
