Top 23 Fft Open-Source Projects

  • FFmpeg

    Mirror of https://git.ffmpeg.org/ffmpeg.git

    • Project mention: Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months | news.ycombinator.com | 2024-04-10

    GPL2

    Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?

    IANAL, apologies if I miss understand license requirements.

  • ffsubsync

    Automagically synchronize subtitles with video.

    • Project mention: The GitHub Black Market That Helps Coders Cheat the Popularity Contest | news.ycombinator.com | 2023-10-23

    > Another giveaway is the ratio of stars to watchers / forks. I remember one project with thousands of stars but only 10 users "watching" it. They went on to raise a sizable seed round too.

    Not necessarily indicative of foul play. I have two projects like this (https://github.com/smacke/ffsubsync and https://github.com/ipyflow/ipyflow) and I attribute it to not having great developer documentation.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • MathNet

    Math.NET Numerics

  • gqrx

    Software defined radio receiver powered by GNU Radio and Qt.

    • Project mention: Listen to HD radio with a $30 RTL SDR dongle | news.ycombinator.com | 2023-11-05

    There's an issue open for this: https://github.com/gqrx-sdr/gqrx/issues/1104

    I could really use some help from a software build expert. Gqrx and all its dependencies would need to be built in CI with Apple silicon support, and I don't know how to do that.

  • kfr

    Fast, modern C++ DSP framework, FFT, Sample Rate Conversion, FIR/IIR/Biquad Filters (SSE, AVX, AVX-512, ARM NEON)

  • VkFFT

    Vulkan/CUDA/HIP/OpenCL/Level Zero/Metal Fast Fourier Transform library

    • Project mention: [P] - VkFFT now supports quad precision (double-double) FFT computation on GPU | /r/MachineLearning | 2023-09-27

    Hello, I am the creator of the VkFFT - GPU Fast Fourier Transform library for Vulkan/CUDA/HIP/OpenCL/Level Zero and Metal. In the latest update, I have added support for quad-precision double-double emulation for FFT calculation on most modern GPUs. I understand that modern ML is going in the opposite low-precision direction, but I still think that it may be useful to have this functionality at least for some prototyping and development of concepts.

  • qspectrumanalyzer

    Spectrum analyzer for multiple SDR platforms (PyQtGraph based GUI for soapy_power, hackrf_sweep, rtl_power, rx_power and other backends)

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • DSWaveformImage

    Generate waveform images from audio files on iOS, macOS & visionOS in Swift. Native SwiftUI & UIKit views.

    • Project mention: Are there any libraries that I can use or any way to make such audio waveforms? I looked into a library called "react-native-audiowaveform" but it's not being maintained anymore and doesn't work for newer versions of RN | /r/reactnative | 2023-05-21

  • Realtime_PyAudio_FFT

    Realtime audio analysis in Python, using PyAudio and Numpy to extract and visualize FFT features from streaming audio.

  • 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

    • Project mention: Tips for DSP | /r/embedded | 2023-05-08

    Since you're using an ARM, you've also got access to CMSIS-DSP, which has most basic DSP functions you'll need already hand optimized for whichever ARM core you have: https://github.com/ARM-software/CMSIS-DSP

  • ministark

    🏃‍♂️💨 GPU accelerated STARK prover built on @arkworks-rs

  • audiowmark

    Audio Watermarking

  • eulerian-remote-heartrate-detection

    Remote heart rate detection through Eulerian magnification of face videos

  • Spectrogram

    .NET library for creating spectrograms (visual representations of frequency spectrum over time) (by swharden)

  • FftSharp

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

  • FFTW.jl

    Julia bindings to the FFTW library for fast Fourier transforms

  • fourier

    Fast Fourier transforms (FFTs) in Rust

  • dblclockfft

    A configurable C++ generator of pipelined Verilog FFT cores

  • RustFFT

    A mixed-radix FFT library written in pure Rust (by awelkie)

  • IQEngine

    A web-based SDR toolkit for analyzing, processing, and sharing RF recordings

    • Project mention: IQEngine: A React-based FOSS project for sharing and analyzing recordings of wireless signals | /r/webdev | 2023-12-04

    One thing we have struggled with is the relatively small intersection between wireless engineers/researchers, and web developers. We are definitely looking for more folks with web dev xp to get involved, and in return you can build expertise within a specific and "hot" field, ie wireless =).
