Sofar
Sofa Reader and Renderer
Features
This crate provides high level bindings to libmysofa
API allows to read
HRTF
filters from SOFA
files (Spatially Oriented Format for Acoustics).
The render
module implements uniformly partitioned convolution algorithm
for rendering HRTF filters.
Example
use sofar::reader::{OpenOptions, Filter};
use sofar::render::Renderer;
// Open sofa file, resample HRTF data if needed to 44_100
let sofa = OpenOptions::new()
.sample_rate(44100.0)
.open("my/sofa/file.sofa")
.unwrap();
let filt_len = sofa.filter_len();
let mut filter = Filter::new(filt_len);
// Get filter at poistion
sofa.filter(0.0, 1.0, 0.0, &mut filter);
let mut render = Renderer::builder(filt_len)
.with_sample_rate(44100.0)
.with_partition_len(64)
.build()
.unwrap();
render.set_filter(&filter);
let input = vec![0.0; 256];
let mut left = vec![0.0; 256];
let mut right = vec![0.0; 256];
// read_input()
render.process_block(&input, &mut left, &mut right).unwrap();
You can run cpal
renderer example like this:
cargo run --example renderer -- <FILENAME-MONO.wav> libmysofa-sys/libmysofa/share/default.sofa
