Both also come as <strong>standalone apps</strong>, so no DAW is needed. Low latency, automatic discovery, optional password protection.</p> <p>The goal: set up in seconds, no frills, it just works.</p> <div class="gallery gallery--2"> <figure><a href="https://www.matthiaskronlachner.com/media/2026/mcfx-send-receive/mcfx_send.png"><img class="diagram" src="https://www.matthiaskronlachner.com/media/2026/mcfx-send-receive/mcfx_send.png" alt="mcfx_send plug-in window" loading="lazy"></a><figcaption>mcfx_send</figcaption></figure> <figure><a href="https://www.matthiaskronlachner.com/media/2026/mcfx-send-receive/mcfx_receive.png"><img class="diagram" src="https://www.matthiaskronlachner.com/media/2026/mcfx-send-receive/mcfx_receive.png" alt="mcfx_receive plug-in window" loading="lazy"></a><figcaption>mcfx_receive</figcaption></figure> </div> <h2 id="why">Why</h2> <p>They were made for spatial audio jam sessions and concerts, where several people bring their laptops and everything has to end up on one loudspeaker system. Proprietary audio-over-network solutions caused a fair share of problems there: license trouble even after buying one, drivers that stop working after an OS update, endpoints that aren&rsquo;t discovered. They are built for hardware units, not for laptops. JackTrip needs JACK; SonoBus does much more than needed and costs a lot of CPU.</p>
