Overview
AMRAudioRecorder is an Android library that enables AMR audio recording with pause and resume functionality. Since Android’s native MediaRecorder doesn’t support pausing AMR recordings, this library implements a clever solution by managing multiple audio segments and merging them seamlessly.Key features
Pause and resume
Pause your recording at any time and resume without losing any audio data
AMR format support
Records audio in AMR-NB format, ideal for voice recordings with small file sizes
Automatic merging
Automatically merges multiple audio segments into a single file when stopped
Simple API
Clean, intuitive API with just a few methods to start, pause, resume, and stop recording
Why AMRAudioRecorder?
Android’s built-in MediaRecorder doesn’t support pause and resume functionality for AMR audio recordings. AMRAudioRecorder solves this by:- Creating separate audio files for each recording segment
- Managing the file headers correctly (skipping AMR’s 6-byte header on subsequent files)
- Merging all segments into a single playable AMR file when you stop recording
- Providing a simple, developer-friendly API that handles all the complexity for you

How it works
The library uses a smart approach to enable pause/resume functionality:- Start recording: Creates a new AMR file and begins recording
- Pause: Stops the current MediaRecorder and releases resources
- Resume: Creates a new MediaRecorder instance and starts a new file
- Stop: Merges all audio segments by:
- Keeping the first file’s 6-byte AMR header
- Skipping headers on subsequent files
- Combining all audio data into a single file
- Cleaning up temporary files
