PCDJ DEX 3 - Quick Demonstration of AIUnmixEQ™

Coming in DEX 3.19: Introducing brand-new DEX 3 feature called AIUnmixEQ™! As the name implies, DEX 3.19 (and up) is using machine learning (deep neural networks, a flavor of AI) to add Real-Time Unmixing/Stem Separation (Music Source Separation). Use DEX 3's Equalizer knobs or kill pads to smoothly separate songs into 3 stems:

• Vocals (High eq knob)
• Instruments (Mid eq knob)
• Drums (Low eq knob)

Our new AIUnmixEQ™ feature brings up new opportunities for DJs and KJs:

• Live mashups and seamless advanced remixing
• On-the-fly acapella or instrumental
• Instant karaoke tracks from regular tracks (with or without
guided vocals)

You can activate this feature from Preferences/Options - General tab: "AIUnmixEQ™ - use the eq knobs as stems: Vocals, Instruments, Drums".

IMPORTANT NOTE: AIUnmixEQ™ is only available on modern Macs/PCs with 8 GB of RAM or more. For performance reasons it is recommended that you also have a dedicated GPU/video card (eg. NVidia, AMD, Apple M1/M2). Works for songs and videos under 15 minutes long. On modern powerful laptops it usually takes 2-3 seconds for AIUnmixEQ™ to analyze and split the audio into stems, but it may take up to 15-20 seconds if you have an older computer - during this time you can still play the track.

Some other important additions and changes we've made in DEX 3.19 (and up):

• The DEX 3 audio engine is now fully 32-bit audio (for comparison, streaming services and CD quality tracks are usually only 16-bit)
• Added support for industry-standard STEM files (files with a
".stem.mp4" extension that contain pre-separated stems: drums, bass, sounds/melody, voice/lead)
• Various performance optimizations

A Few other important notes:

1. Since it's AI based most of the times it works 100% but sometimes it misses. However, even when it doesn't, if you keep the EQs in the reset position, the audio is _exactly_ the same as the original one, nothing at all is lost (quality wise).

2. For Intel-based systems (PCs or Macs) a minimum of Core generation 8 (eg. Core i3 8xxx) is recommended if you don't have a dedicated GPU since before that generation the integrated GPUs are really slow and our AI uses the video card to do it's thing.

3. On lower-end machines that option will be grayed-out and can't be enabled and the software will work just as fast as the previous 3.18 version.

4. On the very first song load, the audio splitting will work a bit slower because the GPU needs to load the AI models and needs to "warm up" - it will usually add another 1-2 seconds extra.
