# sound

Convert matrix of signal data to sound and play it.

## 📝 Syntax

* sound(y)
* sound(y, Fs)
* sound(y, Fs, nBits)
* sound(y, Fs, nBits)

## 📥 Input argument

* y - column vector or m-by-2 matrix.
* Fs - sample rate, a positive number, 8192 by default.
* nBits - bit depth of sample values: 8, 16 (default), 24.

## 📄 Description

sound plays audio signal y to the speaker at sample rate of Fs hertz and uses nBits bits per sample.

## 💡 Example

```matlab
signal = rand(2, 44100) - 0.5;
sound(signal, 44110, 16)

```
