Features

1. Authentication: Secure user authentication is facilitated through Amplify Auth Cognito, enabling users to sign up and sign in effortlessly.

2. Data Recording: Users can efficiently record dBA surround noise during real time. The app captures the stream of audio from the mic then using FFT to convert it into dBA values. After finish recording, user can upload or discard the recording.

3. Data Storage: The Data tab allows users to conveniently view and manage their recorded noise-related data, ensuring easy access and organization. User can upload the data to the AWS S3 buckets or delete it.

4. Settings: Customize your app experience with the Settings tab, providing users with options to modify their StudyID for the research.

Global Variables

The app employs well-organized global variables for efficient data management:

• cache: A map storing the current study ID and information about files already uploaded.
• studyId: A unique identifier for the current study, facilitating seamless data uploads.
• userId: The email address of the current user, ensuring personalized interactions.
• cacheFileName and cacheLastLoginFileName: Files for storing cache and user login timestamp, respectively.
• firstName and lastName: Strings representing the user's first and last names.
• data: A list of DataItem objects, providing a structured approach to managing all data entries.

AWS Amplify Integration

The app seamlessly integrates with AWS Amplify, leveraging powerful AWS services. The _configureAmplify function sets up the connection to AWS, configuring necessary plugins like Amplify Auth Cognito and Amplify Storage S3.
