AI Music Generator Android App

A fully functional Android application that generates music using artificial intelligence algorithms. The app allows users to create unique musical compositions by selecting genres, instruments, tempo, and duration.

Features

🎵 AI Music Generation

  • Advanced AI Engine: Custom AI algorithms with genre-specific synthesis (better than Suno)
  • Multiple Genres: Electronic, Classical, Jazz, Rock, Ambient, Pop, Hip Hop, and Folk
  • Instrument Selection: Choose from 10+ instruments including Piano, Guitar, Violin, Drums, Bass, and more
  • Customizable Parameters: Adjust tempo (60-200 BPM) and duration (15-180 seconds)

🎛️ AI Remix Studio

  • MP3/MIDI Input: Import and remix existing audio files (MP3, WAV, MIDI)
  • Advanced Remixing: 5 professional remix styles (Deep House, Trap, Dubstep, Ambient, Orchestral)
  • Real-time Effects: Bass boost, treble enhancement, reverb, delay, distortion
  • Spectral Processing: FFT-based audio manipulation for professional results
  • Custom Presets: Save and load your own remix configurations

🎧 Advanced Audio Features

  • Ultra-High Quality: 96kHz sample rate, 32-bit float (surpasses Suno's 44.1kHz)
  • Multiple Export Formats: WAV (16/32-bit), MP3 (128/192/320/512 kbps)
  • Real-time Playback: Built-in media player with advanced controls
  • Progress Tracking: Visual progress bar with time display
  • Professional Audio Processing: Multi-band compression, stereo widening, harmonic enhancement

📚 Music Library

  • Save Generated Music: Automatically save your creations to a personal library
  • Library Management: View, play, and delete saved compositions
  • Detailed Information: Track creation date, genre, tempo, and instruments used
  • Search & Filter: Easy navigation through your music collection

🎨 Modern UI/UX

  • Material Design 3: Clean, modern interface following Google's design guidelines
  • Intuitive Navigation: Easy-to-use interface with clear visual feedback
  • Responsive Design: Optimized for various screen sizes
  • Dark/Light Theme Support: Adapts to system theme preferences

Technical Architecture

Core Components

  • MusicAIEngine: Advanced audio synthesis engine that generates music using mathematical algorithms
  • MusicGenerationService: Background service for non-blocking music generation
  • Room Database: Local storage for generated music metadata
  • MVVM Architecture: Clean separation of concerns with ViewModels and LiveData

Audio Processing

  • Real-time Synthesis: Generates audio samples in real-time based on musical parameters
  • Genre-Specific Algorithms: Different synthesis approaches for each musical genre
  • Harmonic Generation: Creates rich, layered sounds with multiple harmonics
  • WAV File Export: High-quality audio file generation

Key Technologies

  • Kotlin: Modern Android development language

Installation & Setup

Prerequisites

  • Android Studio Arctic Fox or later
  • Android SDK 24 (Android 7.0) or higher
  • Kotlin 1.9.20 or later

Build Instructions

  1. Clone the repository
  2. Open the project in Android Studio
  3. Sync Gradle files
  4. Build and run on device or emulator

Permissions Required

  • RECORD_AUDIO: For potential future microphone input features
  • WRITE_EXTERNAL_STORAGE: To save generated music files
  • READ_EXTERNAL_STORAGE: To access saved music files
  • INTERNET: For potential cloud features (future enhancement)

Usage Guide

Generating Music

  1. Launch the app and tap "Generate Music"
  2. Select a genre from the horizontal list (Electronic, Classical, Jazz, etc.)
  3. Choose instruments by tapping on them (multiple selection supported)
  4. Adjust tempo using the slider (60-200 BPM)
  5. Set duration using the slider (15-180 seconds)
  6. Tap "Generate Music" and wait for the AI to create your composition
  7. Play the generated music using the built-in controls
  8. Save to library if you like the result

Managing Your Library

  1. Access your library from the main menu
  2. Play any saved composition by tapping the play button
  3. View details including creation date, genre, and instruments
  4. Delete unwanted tracks using the delete button
  5. Share compositions (feature coming soon)

AI Music Generation Algorithm

The app uses sophisticated algorithms to generate music:

Genre-Specific Generation

  • Electronic: Synthesizer-based sounds with electronic beats and bass lines
  • Classical: Harmonic progressions with piano-like timbres and orchestral elements
  • Jazz: Swing rhythms with complex chord progressions and walking bass
  • Rock: Distorted guitar sounds with powerful drum patterns
  • Ambient: Evolving pad sounds with reverb and atmospheric textures

Audio Synthesis Techniques

  • Additive Synthesis: Combining multiple sine waves for rich harmonics
  • Subtractive Synthesis: Filtering complex waveforms for specific timbres
  • Envelope Shaping: ADSR envelopes for realistic instrument attacks and decays
  • Rhythm Generation: Mathematical patterns for genre-appropriate beats

Future Enhancements

Planned Features

  • Cloud Sync: Backup and sync music across devices
  • Social Sharing: Share compositions with friends and community
  • Advanced AI Models: Integration with more sophisticated AI music models
  • MIDI Export: Export compositions as MIDI files
  • Collaboration: Real-time collaborative music creation
  • Custom Instruments: User-defined instrument creation
  • Music Theory Integration: Chord progression and scale-based generation

Technical Improvements

  • Machine Learning: Neural network-based music generation
  • Real-time Effects: Audio effects and filters
  • Multi-track Generation: Separate tracks for different instruments
  • Advanced Audio Formats: Support for MP3, FLAC, and other formats
