# AudioMorseDecoder
> Dot dot hash!

A C# program that uses NAudio to analyze an audio file and decode the detected morse signal. Currently not particularly tolerant of noise.

Features:

 - A two-tiered buffer system to reduce memory usage when reading long files
 - A multi-step tokeniser
 	 - Extracts context-free tokens from the rolling buffer first
 	 - Converts context-free tokens into contextual tokens second
 - Noise gate to extract first-level tokens
 - AI-like logic to identify the speed of the morse code detected

## Getting Started

### Compiling
Open the solution in Visual Studio / MonoDevelop / Xamarin and hit build. Alternatively, linux users can run `nuget restore && msbuild` in the root of this repository.

### Usage
Use the program like this:

```bash
./MorseDecoder.exe "/path/to/audio/file.wav"
```

In theory, it should support multiple audio file formats as it uses an NAudio `AudioFileReader` to read the samples from the source file.

The output will show the detected morse code, and the deciphered text.
