# OpenTone

DTMF encoding/decoding

## Install

```bash

pip install opentone

```

## Usage

Here is a clone of [GoogleTone](https://chrome.google.com/webstore/detail/google-tone/nnckehldicaciogcbchegobnafnjkcne?hl=en)

```python

from opentone import ToneGenerator, ToneDecoder

import pyshorteners as pyshort

def tiny_link(url):

    tinyurl = pyshort.Shortener().tinyurl.short(url)

    # The consant prefix in the TinyURL is standard and can be

    # removed altogether, and added in the receiving station

    URL = "http://tinyurl.com/"

    url = tinyurl[len(URL):]

    return url

url = "https://hellochatterbox.com"

url = tiny_link(url)

wave_file = "chatterbox_encoded.wav"

tone_gen = ToneGenerator()

tone_gen.encode_to_wave(url, wave_file)

decoder = ToneDecoder()

decoded_url = decoder.decode_wave(wave_file)

assert decoded_url == url

print("http://tinyurl.com/" + decoded_url)

```

NOTE: Input wave files should be 8khz mono

convert files with

```bash

ffmpeg -i some_file.mp3 -acodec pcm_s16le -ac 1 -ar 8000 out.wav

```
