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
