## A/C and C/A processing

Simplifying the analog signal to a quantized form, i.e. replacing values that change smoothly to values that change by leaps and bounds.

A/C processing consists of 3 stages:

* Sampling

* Quantization

* Coding

C/A processing consists of 3 stages:

* Coding

* Quantization

* Sampling

#### Instalation

```text

pip install Pyaudio wave soundfile

```

#### Usage

* Run [Sound.py](https://github.com/JuliaSzymanska/Sound/blob/master/Sound.py)

#### Output

For [Beethoven.wav]() file programme will generate to wav files:

* [Rate_8_Beethoven.wav](https://raw.githubusercontent.com/JuliaSzymanska/Sound/master/Rate_8_Beethoven.wav) with 8  bit depth

* [Rate_16_Beethoven.wav](https://raw.githubusercontent.com/JuliaSzymanska/Sound/master/Rate_16_Beethoven.wav) with 16  bit depth
