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.

Pion is the Modern Stack for Web Real-Time Communication. It implements the WebRTC API. Spend more time building and less time learning a new API. Its feature include PeerConnection API support for DataChannels, Send/Receive audio and video, Renegotiation. It provides API with direct RTP/RTCP access, API also allows developer to pass their own packetizer, Opus, PCM, H264, VP8 and VP9 packetizer, Sender/Receiver Reports, Easy integration with x264, libvpx, GStreamer and ffmpeg and lot more.

PortAudio is a free, cross-platform, open-source, audio I/O library.  It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms. It provides a very simple API for recording and/or playing sound using a simple callback function or a blocking read/write interface. Example programs are included that play sine waves, process audio input (guitar fuzz), record and playback audio, list available audio devices, etc.

rtsp-simple-server is a ready-to-use and zero-dependency server and proxy that allows users to publish, read and proxy live video and audio streams through various protocols like RTSP, RTMP, HLS. It publish and read live streams to the server. It acts as a proxy and serve streams from other servers or cameras, always or on-demand. 
<BR><BR>
Streams are automatically converted from a protocol to another. For instance, it's possible to publish a stream with RTSP and read it with HLS. Each stream can have multiple video and audio tracks, encoded with any codec, including H264, H265, VP8, VP9, MPEG2, MP3, AAC, Opus, PCM, JPEG. It can serve multiple streams at once in separate paths.

A cross-browser implementation of the AudioContext which aims to closely follow the standard. This package provides a subset of the Web Audio API which works in a reliable and consistent way in every supported browser. In contrast to other popular polyfills standardized-audio-context does not patch or modify anything on the global scope. In other words, it does not cause any side effects. It can therefore be used safely inside of libraries.

 p5.speech is a JavaScript library that provides simple, clear access to the Web Speech and Speech Recognition APIs, allowing for the easy creation of sketches that can talk and listen. It consists of two object classes (p5.Speech and p5.SpeechRec) along with accessor functions to speak and listen for text, change parameters (synthesis voices, recognition models, etc.), and retrieve callbacks from the system. Speech recognition requires launching from a server (e.g. a python simpleserver on a local machine).
