Top 7 C++ Fft Projects

  • GitHub repo VkFFT

    Vulkan/CUDA/HIP/OpenCL Fast Fourier Transform library

    Project mention: The AMD “Aldebaran” GPU That Won Exascale | news.ycombinator.com | 2021-11-15

    Incorrect. Vulkan has compute shaders[1], which are generally usable. Libraries like VkFFT[2] demonstrate basic signal processing in Vulkan. This can certainly be expanded upon, & there are numerous other non-graphical uses.

    There is a Vulkan ML TSG (Technical Subgroup), which is supposed to be working on ML. Even Nvidia is participating, with extensions like VK_NV_cooperative_matrix, which specifically target the ml tensor cores.

    There's people could probably say this better/more specifically, but I'll give it a try: Vulkan is, above all, an general standard for dispatching & orchestrating work usually on a GPU. Right now that work is most of often graphics, but that is far from a limit.

    SYCL is, imo, the opposite of where we need to go. It's the old historical legacy that CUDA has, of writing really dumb ignorant code & hoping the tools can make it run well on a GPU. Vulkan, on the other hand, asks us to consider deeply what near-to-the-metal resources we are going to need, and demands that we define, dispatch, & complete the actual processing engines on the GPU that will do the work. It's a much much much harder task, but it invites in fantastic levels of close optimization & tuning, allows for far more advanced pipelining & possibilities. If the future is good, it should abandon SYCL and CUDA, and bother to get good at Vulkan.

  • GitHub repo rocFFT

    Next generation FFT implementation for ROCm

    Project mention: "error making: rocfft" when installing rocm-tensorflow | reddit.com/r/ROCm | 2021-06-29

    Might make sense to raise an issue at https://github.com/ROCmSoftwarePlatform/rocFFT ?

  • Scout APM

    Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

  • GitHub repo audiowmark

    Audio Watermarking

    Project mention: How to create 40Khz+ sound waves? | reddit.com/r/livesound | 2021-01-03
  • GitHub repo OceanFFT

    OpenGL Demo: Simulating Ocean Waves with FFT

    Project mention: Tessendorf-style ocean waves simulation in OpenGL compute shaders. Link to the source code in comments, which in turn links to all the resources I used, so you can make your own! | reddit.com/r/GraphicsProgramming | 2021-02-22
  • GitHub repo tinyspec-cling

    tiny spectral synthesizer with livecoding support

    Project mention: Interactive C++ for Data Science | news.ycombinator.com | 2020-12-23

    Here's a live coding music synth based on Cling https://github.com/nwoeanhinnogaehr/tinyspec-cling

  • GitHub repo HubAlyzer

    A spectrum analyzer display for HUB75 RGB LED panels and I2S microphones

    Project mention: Simples Audio Spectrum Analyser Project with HUB75E LED Matrix | reddit.com/r/esp32 | 2021-10-01

    Very cool! I'm currently doing something similar, but with an I2S mic and processing on the ESP https://github.com/HorstBaerbel/HubAlyzer Might add streaming to the ESP too for more processing power. Having a standalone mode is nice though...

  • GitHub repo audio-thingies

    Playground for experimenting with audio processing

    Project mention: audio processing fundamentals with C++ | reddit.com/r/cpp | 2021-10-11

    I played around with capturing/playing/processing audio with SDL2. It aint much, but you can use the capture/playback classes as a starting point. Works on Windows and Linux alike.

  • Nanos

    Run Linux Software Faster and Safer than Linux with Unikernels.
