Cythara

A musical instrument tuner for Android.

It's a fork from Cythara with same changes:

Converted the code to Kotlin
Organized the layers using Clean Architecture
New layouts
Removed third-party components

Functionality

Provides tunings for various instruments and supports chromatic tuning.
Displays deviations between -30 and 30 cents.
Supports scientific pitch notation and Solfège.

Tests

Run ./gradlew test to run all unit tests. In addition, there are UI tests based on image comparisons which can be run using ./gradlew connectedCheck. The reference images are generated using a Nexus 5X emulator (resolution: 1080 x 1920, 420 dpi) with API level 26.

Libraries

The Tarsos DSP library (https://github.com/JorenSix/TarsosDSP) is used for pitch detection.
