kfr

2 1,582 9.2 C++

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

9 1,138 9.9 C++

A generic satellite data processing software.

Project mention: My Shortwave Dipole Antenna | /r/RTLSDR | 2023-05-25

A note on using GLRPT - currently there aren't any satellites up with functioning LRPT transmissions. Hopefully this year Russia will get another Meteor satellite up and we can start receiving LRPT signals again. Also you may find it more convenient to use SatDump for working some satellites as it connects directly to the SDR without needing GQRX and a virtual audio cable.

- Ladder Filter: ported from an implementation of the improved Moog Ladder Filter - Dual State Variable Filter: implemented a dual filter based on Emillie's State Variable Filter - Reverbs: added 4 reverbs based on the implementations found in Rings, Clouds and Elements.

phantom

3 14 1.8 C++

[BETA] Modern phase distortion synthesizer plugin (targeting VST3 and AU) :musical_keyboard: (by blackboxdsp)
web-logic-analyzer

1 14 2.7 C++

Web-based Logic Analyzer for ESP8266 and ESP32 that can be controlled and viewed via web browser also supports button controls and can produce output for PulseView.
Band-Split-Delay

1 1 0.0 C++

Band Split Delay plugin which will hopefully be released to the public one day. The aim of this plugin is to offer 3 bands each with their own reverb and delay settings. The inspiration for this came from FL Studio's Patcher, in which I've made this exact thing and it sounds awesome when paired with the right instruments.
