//! # 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.
//!
//! [`libmysofa`]: https://github.com/hoene/libmysofa
//! [`render`]: `crate::render`
//!
//! # Example
//!
//! ```no_run
//!
//! 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();
//! ```
