additive-synthesis

C Pixels-based graphical audio synthesizer implemented as a WebSocket server

Python music synthesizer scripts (input also via ABC or MIDI)

Extreme-fidelity synthesis of musical elements, based on the MASS framework

32-partial additive synthesizer laid out like a 32-channel mixer. Every channel is one sine oscillator locked to a harmonic of the played note, and every channel has its own tuning, envelope and modulation.

Csound Package Manager

verilog example to drive PCM5102 DAC with FPGA

kNN-SVC: Robust Zero-Shot Singing Voice Conversion with Additive Synthesis and Concatenation Smoothness Optimization

A standalone synthesizer that is controlled through text files in an extendable way.

An additive synthesiser that generates wavetable from an input sample by using linear regression to find weights of harmonics. Currently being developed in Python (Pyo, PyQt5, wxpython). Working to update this to a web-based sound synth! .

Jagex Synth Editor

C++ library for analysis, manipulation, and synthesis of sound using the Reassigned Bandwidth-Enhanced Additive Sound Model

A drone-ambient synthesizer for slowly breathing clusters: just intonation, a conductor that plays all night, distance as the one number that shapes every voice, 24 source types, three reverb tiers, and 14592 presets measured by rendering them. Framework-free C++20 core, JUCE shell. VST3 + standalone.

A tool set for translating between images and sound in the frequency domain

Custom oscillator for the Korg NTS-1 modelling Risset's Bell

An app that resynthesises musical instrument sounds based on the STFT analysis and additive synthesis based on a sinusoidal model.

Real-time Python MIDI synthesizers (additive/FM/wavetable synthesis)

Transduction

Helps to create experimental music from a file (or its part) and a Ukrainian text. It can also generate a timbre for the notes. Uses SoX inside.

modern additive synth engine in rust

Caecilia — an open-source hybrid pipe-organ virtual instrument (VST3/AU/Standalone, JUCE/C++20): per-rank additive voice engine, audio-rate wind model with tremulant, lock-free real-time core, queryable semantic registration.
