FastLEDHub-AudioViz is a command line tool that can be used to send spectrum data from a Windows audio device to an ESP32 or ESP8266 running [FastLEDHub](https://github.com/srwi/FastLEDHub). The transmitted data consists of 16 bins corresponding to different frequency ranges in the audio spectrum. It can send data to multiple devices via a websocket connection. More information can be found in the [FastLEDHub](https://github.com/srwi/FastLEDHub) documentation.

## Example usage

Transmit spectrum to a single device:

```console

$ FastLEDHubAudioViz 192.168.0.42

```

Transmit spectrum to multiple devices and visualize in the terminal window:

```console

$ FastLEDHubAudioViz 192.168.4.2 192.168.13.37 --visualize

```

## Help

```console

$ FastLEDHubAudioViz --help

Options:

  -h,--help                         Print this help message and exit

  -v,--visualize                    Visualize spectrum in terminal

  -m,--microphone                   Use microphone to capture audio (default: system audio)

  -p,--period FLOAT:POSITIVE        Data transmission period (default: 10 [ms])
