Java WFDB Library

This library is a pure Java implementation of the Waveform Database(WFDB) specifications.

What is WFDB?

Waveform Database (WFDB) is a set of file standards designed for reading and storing physiologic signal data, and associated annotations backed by MIT-LCP members.

Features:

• Parse single-segment and multi-segment records
• Support for signal format: 8, 16, 24, 32, 61, 80, 160, 212, 310, 311
• Support for different signal formats and files
• Filter by a range of time
• Filter by signals indices
• Export single-segment and multi-segment records

Usage

Parse a single-segment record:

Path path = Path.of(...);
SingleSegementRecord record = SingleSegmentRecord.parse(path);

Parse and filter a single-segment record by time:

Path path = Path.of(...);
long start = 0; // 0 millisecond
long end = 1000; // first second 
Filter filter = new Filter.Builder().startTime(start).endTime(end).build();
SingleSegementRecord record = SingleSegmentRecord.parse(path, filter);

Parse and filter a single-segment record by signal indices:

Path path = Path.of(...);
Filter filter = new Filter.Builder().signals(new int[]{0, 1, 2}).build();
SingleSegementRecord record = SingleSegmentRecord.parse(path, filter);

Parse a multi-segment record:

Path path = Path.of(...);
MultiSegmentRecord record = MultiSegmentRecord.parse(path);

Export a single-segment record:

...
SingleSegmentRecord record = SingleSegmentRecord.parse(path, filter);
Path exportPath = Path.of(...);
record.export(exportPath);
