vst3sdk - VST 3 Plug-In SDK

•    CMake

---

A VST Plug-in is an audio processing component that is utilized within a host application. This host application provides the audio or/and event streams that are processed by the Plug-in's code. Generally speaking, a VST Plug-in can take a stream of audio data, apply a process to the audio, and return the result to the host application. A VST Plug-in performs its process normally using the processor of the computer. The audio stream is broken down into a series of blocks. The host supplies the blocks in sequence. The host and its current environment control the block-size. The VST Plug-in maintains the status of all its own parameters relating to the running process: The host does not maintain any information about what the Plug-in did with the last block of data it processed. From the host application's point of view, a VST Plug-in is a black box with an arbitrary number of inputs, outputs (Event (MIDI) or Audio), and associated parameters. The host needs no implicit knowledge of the Plug-in's process to be able to use it. The Plug-in process can use whatever parameters it wishes, internally to the process, but depending on the capabilities of the host, it can allow the changes to user parameters to be automated by the host.

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

•    Jupyter

---

Essentia is an open-source C++ library for audio analysis and audio-based music information retrieval released under the Affero GPL license. It contains an extensive collection of reusable algorithms which implement audio input/output functionality, standard digital signal processing blocks, statistical characterization of data, and a large set of spectral, temporal, tonal and high-level music descriptors. The library is also wrapped in Python and includes a number of predefined executable extractors for the available music descriptors, which facilitates its use for fast prototyping and allows setting up research experiments very rapidly. Furthermore, it includes a Vamp plugin to be used with Sonic Visualiser for visualization purposes. Essentia is designed with a focus on the robustness of the provided music descriptors and is optimized in terms of the computational cost of the algorithms. The provided functionality, specifically the music descriptors included in-the-box and signal processing algorithms, is easily expandable and allows for both research experiments and development of large-scale industrial applications. If you use example extractors (located in src/examples), or your own code employing Essentia algorithms to compute descriptors, you should be aware of possible incompatibilities when using different versions of Essentia.

patchfield - Audio infrastructure for Android

•    Java

---

Patchfield is an audio infrastructure for Android that provides a simple, callback-driven API for implementing audio modules (such as synthesizers and effects), a graph-based API for connecting audio modules, plus support for inter-app audio routing. It is inspired by JACK, the JACK audio connection kit.Patchfield consists of a remote or local service that acts as a virtual patchbay that audio apps can connect to, plus a number of sample apps that illustrate how to implement audio modules and how to manipulate the signal processing graph. The implementation resides entirely in userland and works on many stock consumer devices, such as Nexus 7 and 10.

Tone.js - A Web Audio framework for making interactive music in the browser

•    Javascript

---

Tone.js is a Web Audio framework for creating interactive music in the browser. The architecture of Tone.js aims to be familiar to both musicians and audio programmers creating web-based audio applications. On the high-level, Tone offers common DAW (digital audio workstation) features like a global transport for synchronizing and scheduling events as well as prebuilt synths and effects. Additionally, Tone provides high-performance building blocks to create your own synthesizers, effects, and complex control signals.

snapcast - Synchronous multiroom audio player

•    C++

---

Snapcast is a multiroom client-server audio player, where all clients are time synchronized with the server to play perfectly synced audio. It's not a standalone player, but an extension that turns your existing audio player into a Sonos-like multiroom solution. Audio is captured by the server and routed to the connected clients. Several players can feed audio to the server in parallel and clients can be grouped to play the same audio stream. One of the most generic ways to use Snapcast is in conjunction with the music player daemon (MPD) or Mopidy. The encoded chunks are sent via a TCP connection to the Snapclients. Each client does continuous time synchronization with the server, so that the client is always aware of the local server time. Every received chunk is first decoded and added to the client's chunk-buffer. Knowing the server's time, the chunk is played out using a system dependend low level audio API (e.g. ALSA) at the appropriate time. Time deviations are corrected by playing faster/slower, which is done by removing/duplicating single samples (a sample at 48kHz has a duration of ~0.02ms).
