Top 23 Dsp Open-Source Projects

  • librosa

    Python library for audio and music analysis

    Project mention: Open Source Libraries | /r/AudioAI | 2023-10-02

    librosa/librosa: Python library for audio and music analysis

  • gnuradio

    GNU Radio – the Free and Open Software Radio Ecosystem

    Project mention: Upsampling in Gnuradio is necessary? | /r/sdr | 2023-08-11

    In gr-dtv transmitter examples for Gnuradio, I see some times people use a resampler block before the RF hardware sink. Say our sampling rate is ~9.14Msps which satisfies the Nyquist criterion because our samples are complex numbers.

  • 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.

  • essentia

    C++ library for audio and music analysis, description and synthesis, including Python bindings

  • faust

    Functional programming language for signal processing and sound synthesis (by grame-cncm)

    Project mention: My Sixth Year as a Bootstrapped Founder | news.ycombinator.com | 2024-02-16

    Glicol looks very cool! Also check out Faust if you haven't (https://faust.grame.fr), another FP sound programming language.

  • awesome-musicdsp

    A curated list of my favourite music DSP and audio programming resources

  • inspectrum

    Radio signal analyser

  • glicol

    Graph-oriented live coding language and music/audio DSP library written in Rust

    Project mention: Velato: A programming language where source code must be a valid MIDI music file | news.ycombinator.com | 2024-03-04

    Interesting!

    Similar note-based expression can be found on TidalCycles/Strudel. although it's not valid MIDI format anymore, you can use notation like c4, f3, and make them as "pattern". Samples are also supported in the same manner:

    https://strudel.cc/

    And in my project Glicol, I use only numbers in the seq node. So 60 means middle C. Underscore means rest.

  • 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.

    Project mention: Numerical Computing in C++ Discussion | /r/cpp | 2023-04-01

    Looking around for a bit, some suggestions are GNURadio, ROOT, Armadillo and KFR.

  • pyo

    Python DSP module

  • matchering

    🎚️ Open Source Audio Matching and Mastering

    Project mention: Top 10 AI Mixing and Mastering Tools for Musicians | /r/LALALAI | 2023-06-01

    Songmastr is a web-based AI mastering tool. Utilizing the power of the open-source Python library called Matchering, Songmastr is able to create a masterful audio track that matches a reference song of your choosing. The algorithm studies the RMS, FR, peak amplitude and stereo width of your reference track before applying it to the target audio file.

    A Powerful DSP Library in C++

    Project mention: Ask HN: Manufacturing somewhat novel MIDI controller | news.ycombinator.com | 2023-11-10

    You are about to bite off a lot. Ignore all the other advice in this thread, I do this for a living.

    You have some software experience, this is good. Assuming you have embedded software experience (which is essential for what you are doing and not at all like web programming) you have a foothold to finish this project without going completely insane.

    Hardware is a completely different beast. With software everything happens in your head and when you get stuck you can usually think your way out of it. With hardware, you really do need to learn to do things meticulously and step by step. There are many things that can go wrong. You will learn a lot on this journey.

    Don't be afraid to ask for help. Finding a hardware community will be essential to do this as you learn the skills you need. You're going to make a lot of mistakes, best to go in embracing it

    A good place to start is to join an open source community for MIDI. Two off the top of my head is http://www.ucapps.de/ for MIDI specific hardware and https://www.electro-smith.com/daisy

    A large amount of the work you will find yourself doing at the beginning is just figuring out where and who to ask questions about things like the keybed and other hardware issues. None of this is terribly 'hard' but none of it is easy. Most of it comes from experience.

    It is almost always best to use someone else's product when you are designing your first. Roger Linn (https://www.rogerlinndesign.com/) gave me some fantastic advice a couple years ago when I was trying to design switch caps: "Do you want to be a company that designs switch caps or one that designs synthesizers?" and that stuck. I don't want to design switch caps, so I bought them off the shelf, contracted someone to design my own, and moved on.

    So to that end... just buy a couple keybeds from Fatar or someone else, or just grab a synth you already have or buy one off ebay and harvest the keybed from that (often times much cheaper than buying direct!)

    Don't be afraid to spend money on tools. If you find something difficult, like soldering, I have not once regretted spending money on better tools. They grow with you and save you hundreds if not thousands of hours of unnecessary frustration. When you know you need a tool, find a way to get it.

    Maybe I should make a blog post about this... hmm

    Hope that helps!
