## What it is
A robust Android audio encapsulation library wrapping MediaRecorder and MediaPlayer for recording and playing audio, with partial RxJava support. It simplifies recording to files and playing files or raw resources with configurable volume and looping.

## Use cases
- record audio from the microphone to a file on Android
- play an audio file with looping and volume control
- play a bundled raw audio resource
- record AAC/MPEG-4 audio with configurable sample rate and bitrate
- play audio asynchronously with RxJava observables

## When to choose
- you need a simple, battle-tested wrapper around Android's MediaRecorder/MediaPlayer APIs
- your Android app uses RxJava and you want reactive audio playback
- you want to avoid boilerplate for recording and playing audio files or resources

## When to avoid
- you need streaming audio, real-time processing, or advanced DSP features
- your project does not use RxJava and you prefer plain callbacks
- you need actively maintained support for the latest Android versions - the last release was 2021
- you need cross-platform (non-Android) audio support

## Facets
- artifact type: library
- maturity: maintenance
- function: audio-processing, sdk
- domain: mobile-development, android-tools
- platform: jvm
- tags: rxjava, audio-recording, audio-playback, mediarecorder, mediaplayer, wrapper-library, audio, android
