The utility plugin to help all sound professionals

Say goodbye to complexity and experience a smoother, more efficient audio production process with AudioMatrix by your side. Your audio engineering tasks are now simplified, allowing you to focus on unleashing your creative potential with ease.

AudioMatrix is a channel routing plugin, allowing users to easily reroute any input to any output. Either using regular connections or special gain values (-3 dB, -6 dB, or custom values), with or without polarity changes, AudioMatrix offers you a flexible way to change connections. With support for up to 64 channels of audio, AudioMatrix is the tool that any sound professional should have in their toolset, either working in stereo, surround or immersive.

AudioMatrix GUI

Some use cases:

  • Speaker Array Management: create speaker arrays to reproduce 5.1 audio in a 7.1 studio, using all surround speakers and with the right levels.

  • Bring to Center: temporarily send any signal to the center channel, for easier fine tune when working with immersive sounds.

  • Middle-Side conversion: Convert stereo to Mid-Side (and back to stereo), for additional flexibility in terms of stereo FX processing.

  • Mirror: flip your sounds left ↔ right for a better fit with the image, from stereo to complex 7.1.2 soundscapes.

  • Big Mono: transform your immersive audio into a big mono sound in the blink of an eye, or create custom mono sounds controlling the contribution of each channel.

  • LFE Control: control LFE level independently of all remaining channels.

  • Send to the Sub-Woofer: gather audio from all channels into the sub-woofer, if you don’t have a bass management system.

  • Basic Upmixing/Downmixing: fast way to upmix or downmix something, controlling the contribution of each channel.

  • Format conversion: working with different 5.1 formats? Simply convert from 5.1 Film to 5.1 SMPTE by changing channel ordering.

Nuno Fonseca, founder and CEO of Sound Particles, says: “Audio tools come in all sizes and shapes. Some create beautiful sounds, others are simply useful, saving us time or opening the door to a new world of possibilities. AudioMatrix is one of such tools.”
