About:
Libsoxr is a high-quality, one-dimensional sample-rate conversion library that provides efficient resampling algorithms. It offers a trade-off between performance and audio quality, making it suitable for both real-time and offline processing. The library is designed to be lightweight and easily integrated into various multimedia applications.

Key Features:

High-quality linear-phase FIR filters
Variable-rate conversion support
Low CPU overhead and efficient processing
Simple C API for easy integration

Use Cases:

Real-time audio resampling in digital audio workstations
Converting audio files to different sample rates during transcoding
Upsampling or downsampling in embedded audio systems

Alternatives:

libsamplerate – Libsoxr is often faster and more lightweight, while libsamplerate offers ultra-high quality modes at the cost of performance.
FFmpeg (aresample filter) – FFmpeg provides a comprehensive suite of audio filters including resampling, but is a much larger dependency than libsoxr.
