x42 Balance.lv2

Balance.lv2 is an audio-plugin for stereo balance control with optional per channel delay.

balance.lv2 facilitates adjusting stereo-microphone recordings (X-Y, A-B, ORTF). But it also generally useful as "Input Channel Conditioner". It allows for attenuating the signal on one of the channels as well as delaying the signals (move away from the microphone). To round off the feature-set channels can be swapped or the signal can be downmixed to mono after the delay.

It features a Phase-Correlation meter as well as peak programme meters according to IEC 60268-18 (5ms integration, 20dB/1.5 sec fall-off) for input and output signals.

SonoBus

SonoBus is an easy to use application for streaming high-quality, low-latency peer-to-peer audio between devices over the internet or a local network.

Simply choose a unique group name (with optional password), and instantly connect multiple people together to make music, remote sessions, podcasts, etc. Easily record the audio from everyone, as well as playback any audio content to the whole group.

Connects multiple users together to send and receive audio among all in a group, with fine-grained control over latency, quality and overall mix. Includes optional input compression, noise gate, and EQ effects, along with a master reverb. All settings are dynamic, network statistics are clearly visible.

Works as a standalone application on macOS, Windows, iOS, and Linux, and as an audio plugin (AU, VST) on macOS and Windows. Use it on your desktop or in your DAW, or on your mobile device.

Easy to setup and use, yet still provides all the details that audio nerds want to see. Audio quality can be instantly adjusted from full uncompressed PCM (16, 24, or 32 bit) or with various compressed bitrates (16-256 kbps per channel) using the low-latency Opus codec, and you can do this independently for any of the users you are connected with in a group.

Ingen

Ingen is a modular audio processing system for Jack and LV2 based systems.

Ingen is built around LV2 technology and a strict separation of engine from user interface. The engine is controlled exclusively through a protocol, and can execute as a headless process, with an in-process GUI, or as an LV2 plugin. The GUI can run as a program which communicates over a Unix or TCP/IP socket, or as an embeddable LV2 GUI which communicates via LV2 ports.

Any saved Ingen graph can be loaded as an LV2 plugin on any system where Ingen is installed. This allows users to visually develop custom plugins for use in other applications without programming.
