  • sleef

    SIMD Library for Evaluating Elementary Functions, vectorized libm and DFT

    • Project mention: The Case of the Missing SIMD Code | news.ycombinator.com | 2023-06-08

    I'm the main author of Highway, so I have some opinions :D Number of operations/platforms supported are important criteria.

    A hopefully unbiased commentary:

    Simde allows you to take existing nonportable intrinsics and get them to run on another platform. This is useful when you have a bunch of existing code and tight deadlines. The downside is less than optimal performance - a portable abstraction can be more efficient than forcing one platform to exactly match the semantics of another. Although a ton of effort has gone into Simde, sometimes it also resorts to autovectorization which may or may not work.

    Eigen and SLEEF are mostly math-focused projects that also have a portability layer. SLEEF is designed for C and thus has type suffixes which are rather verbose, see https://github.com/shibatch/sleef/blob/master/src/libm/sleef... But it offers a complete (more so than Highway's) libm.

  • CMSIS-DSP

    CMSIS-DSP embedded compute library for Cortex-M and Cortex-A

  • FftSharp

    A .NET Standard library for computing the Fast Fourier Transform (FFT) of real or complex data

  • CCWT

    Complex Continuous Wavelet Transform

  • libmpegh

    MPEG-H 3D Audio Low Complexity Profile Decoder. Encoder: https://github.com/ittiam-systems/libmpeghe

    • Project mention: Best solution for decoding mpeg-h 3d Audio. | /r/audiophile | 2023-05-29

  • libspecbleach

    C library for audio noise reduction and other spectral effects

    • Project mention: SoX noise reduction | /r/linuxaudio | 2023-07-12

    https://github.com/lucianodato/libspecbleach is a marvelous denoiser. This library includes two example programs (with hardcoded parameters) that you can try as is or customize to your liking. adenoise_demo works without you specifying the section of noise, but the first half a second of recorded audio will be gradually less noisy while it adapts. denoise_demo learns the noise profile on the first 4096 samples and denoises the rest (so the output is 4096 samples short).
