sound_analyzer

A simple Flutter application that measures the current amplitude of the microphone in dB and can save recordings as .wav files

Sound Anaylyzer

There is only one file of code in this demo project - lib/main.dart

I used two different libraries

• flutter_sound to measure the amplitude in dB
• recorder_wav to save a wav file

Note: There is a possibility that we could get the raw amplitude of the microphone

Building the Project

1. Download and install flutter by following the online instructions
2. Clone this repo
3. Open terminal and type flutter doctor to make sure everything is set up correctly.
4. Connect a device to your computer (or run an emulator)
5. Type flutter run in terminal to build and run the project on your device
6. Feel free to mess around with the code and press r in the terminal to hot reload
