Pitch Perfect

Pitch Perfect is a Flutter application that can detect a user's voice or instruments and return the corresponding musical notes (C, D, E, F, G, A, B). This app provides real-time pitch detection and is designed to help users improve their singing or instrument playing skills.

Features

• Real-time pitch detection: The app captures audio samples from the device's microphone and uses the pitch_detector_dart library to analyze the pitch frequency.
• Note identification: The pitchupdart library is used to map the detected pitch to the closest musical note.
• Start/Stop functionality: Users can start and stop the pitch detection process by tapping the image on the screen.
• User-friendly interface: The app displays the detected note in a large font, providing immediate feedback to the user. It also shows a status message to guide the user on when to start or stop singing/playing.

Frameworks and Libraries Used

The Pitch Perfect app is built using the Flutter framework. The following frameworks and libraries were used to implement specific features:

• permission_handler: Used to handle permission requests for microphone access.
• flutter_audio_capture: Provides audio capture functionality for accessing audio samples from the device's microphone.
• google_mobile_ads: Used to display banner ads within the app.
• pitch_detector_dart: Library for pitch detection from audio samples.
• pitchupdart: Library for note identification based on pitch frequency.
