# SamplesBuffer

# Class: SamplesBuffer

Defined in: [index.d.ts:837](https://github.com/simular-ai/simulang-js-internal/blob/d2b85c3277cbb16ce50c0781e1db8ad2c8a5690e/index.d.ts#L837)

A buffer of samples treated as a source.

## Constructors

### Constructor

> **new SamplesBuffer**(`channels`, `sampleRate`, `samples`): `SamplesBuffer`

Defined in: [index.d.ts:846](https://github.com/simular-ai/simulang-js-internal/blob/d2b85c3277cbb16ce50c0781e1db8ad2c8a5690e/index.d.ts#L846)

Creates a new buffer from raw PCM samples.

`channels` is the number of interleaved channels (1 = mono,
2 = stereo). `sample_rate` is samples per second per channel
(e.g. 16000, 44100).  `samples` is an array of f32 audio
samples in `[-1.0, 1.0]`.

#### Parameters

##### channels

`number`

##### sampleRate

`number`

##### samples

`number`\[]

#### Returns

`SamplesBuffer`
