We provide a simple Windows UHJ stereo to Ambisonic B-Format conversion tool for Windows. It converts stereo material that is in the UHJ format (typically from Nimbus Records) into Ambisonic B-Format .AMB files (using FuMa encoding and just the WXY channels). It uses the “naive” speaker-agnostic approach to this.
Autometa is a minimalist, customizable JScript Panel script designed to quickly create autoplaylists based on the current track’s tags with a single click (similar to the quick search function).

AudioGridder is a network bridge for audio and MIDI that allows for offloading the DSP processing of audio plugins to remote computers. This can come in handy when mixing complex projects or running CPU intensive instruments.
AudioGridder Server runs on a computer hosting your effect and instrument plugins. On your workstation, on which you run your DAW, you use the AudioGridder FX or instrument plugin to access your plugin library over the network. The plugin is looking for available servers on your network and once connected allows you to create insert chains or load instruments. Midi and audio data from your DAW will be streamed over the network, processed on the server and streamed back.
