With our latest software updates, we’ve further refined the second generation of our magnetic audio processing system, powered by the SMDS 2.0 algorithm. These improvements significantly enhance wow and flutter correction, resulting in more stable and natural playback. Some early feedback even suggests it can outperform the sound of a traditional projector. When combined with our low-flutter scanning mode, flutter artifacts can often be fully eliminated with minimal user adjustment.
You can see the results for yourself in our latest video: https://www.youtube.com/watch?v=t45T0mJoXQ8&t=521s
At the same time, we’ve also released the second generation of our optical soundtrack extraction engine in recent AxionFlow™ updates. This update is largely shaped by user feedback and introduces a range of new features, along with meaningful improvements in reconstruction quality. With sub-frame synchronization accuracy, the new engine delivers cleaner, more consistent audio output.
