Sofar

Pure Rust SOFA Reader and HRTF Renderer

This crate provides a pure Rust implementation for reading HRTF filters from SOFA files (Spatially Oriented Format for Acoustics).

The render module implements uniformly partitioned convolution algorithm for rendering HRTF filters.

Based on the libmysofa C library by Christian Hoene / Symonics GmbH.

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();
