VoiceDistanceTracker

VoiceDistanceTracker is an Android application that calculates the distance of speaking using sound propagation principles. This project is primarily written in Java with some shell scripts.

Architecture Design

Overview

The VoiceDistanceTracker is an Android application that calculates the speaking distance using sound propagation. The application primarily consists of the following components:

1. UI Layer: Handles the user interface and user interactions.
2. Business Logic Layer: Contains the logic for calculating the distance based on sound propagation.
3. Data Layer: Manages the data input and output, including sound data acquisition.

Components

1. UI Layer

   • Activities: MainActivity, SettingsActivity
   • Fragments: DistanceFragment, SettingsFragment
   • Views: Custom views for displaying distance and settings

2. Business Logic Layer

   • DistanceCalculator: Core logic for calculating the distance based on sound propagation.
   • SoundProcessor: Processes the sound input to extract relevant data for distance calculation.

3. Data Layer

   • SoundRecorder: Manages the recording of sound input.
   • PreferencesManager: Handles saving and retrieving user preferences.

Data Flow

1. Sound Recording:

   • The SoundRecorder component captures sound input from the microphone.
   • The recorded sound data is passed to the SoundProcessor.

2. Sound Processing:

   • The SoundProcessor analyzes the sound data to extract relevant metrics.
   • The processed data is sent to the DistanceCalculator.

3. Distance Calculation:

   • The DistanceCalculator uses the sound propagation formula to calculate the distance.
   • The calculated distance is then updated in the UI.

4. User Interface Update:

   • The UI components (Activities, Fragments, Views) display the calculated distance to the user.
   • User preferences are managed by the PreferencesManager and can be adjusted in the Settings section.
