# bwavfile
|
|
Rust Wave File Reader/Writer with Broadcast-WAV, MBWF and RF64 Support
|
|
|
|
### Features
|
|
|
|
This is currently a work-in-progress! However many features presently work:
|
|
|
|
- [x] Read standard WAV, Broadcast-Wave, and 64-bit RF64 and BW64 wave files with one interface for
|
|
all types with transparent format detection.
|
|
- [ ] Wave/RF64 file writing with transparent promotion from WAV to RF64.
|
|
- [x] Unified format definition interface for standard and extended-format wave files.
|
|
- [x] Read channel/speaker map metadata.
|
|
- [x] Read standard EBU Broadcast-Wave metadata and decode to fields, including timestamp and SMPTE UMID.
|
|
- [x] iXML and ADM XML metadata.
|
|
- [ ] Broadcast-WAV Level and Quality metadata.
|
|
- [ ] Cue list, label, and labeled text metadata.
|
|
- [ ] Sampler and instrument metadata.
|
|
- [x] Validate the compatibility of a given wave file for certain regimes.
|
|
- [x] Metadata support for ambisonic B-format.
|
|
|
|
|
|
## Use Examples
|
|
|
|
### Reading Audio Frames From a File
|
|
|
|
```rust
|
|
|
|
use bwavfile::WaveReader;
|
|
let mut r = WaveReader::open("tests/media/ff_silence.wav").unwrap();
|
|
|
|
let format = r.format().unwrap();
|
|
assert_eq!(format.sample_rate, 44100);
|
|
assert_eq!(format.channel_count, 1);
|
|
|
|
let mut frame_reader = r.audio_frame_reader().unwrap();
|
|
let mut buffer = frame_reader.create_frame_buffer();
|
|
|
|
let read = frame_reader.read_integer_frame(&mut buffer).unwrap();
|
|
|
|
assert_eq!(buffer, [0i32]);
|
|
assert_eq!(read, 1);
|
|
```
|
|
|
|
## Note on Testing
|
|
|
|
All of the media for the integration tests is committed to the respository
|
|
in zipped form. Before you can run tests, you need to `cd` into the `tests`
|
|
directory and run the `create_test_media.sh` script. Note that one of the
|
|
test files (the RF64 test case) is over four gigs in size.
