Beat Energizer | Sonic Revitalizer

Looking for that extra punch and energy to make your mark in the crowded music scene? Look no further – FAC Punchlab is your solution, an all-in-one super audio rack with 9 precision audio processors, ready to energize and revitalize your sound!

FAC Punchlab, your sonic atelier, empowers you to design and showcase the unique characteristics of your instruments:

The signal flow is not fixed; you can customize it as you wish by rearranging the positions of each audio processor, excluding clip and mix. Simply toggle the flow button and drag the FX to your desired position.

Whether you're a novice in music production or an avid amateur musician exploring various genres, this tool is sure to ignite your creative spark! Following the diagram below, the sound flows from the left to right, or from the input to the output.

Lookahead and Oversampling

FAC Punchlab reports to the host the (low) latency related to the audio processing. Check that your host provides "Latency Compensation"

Always check your audio levels

In general, use the gain in parsimony, to avoid any excessive levels that may damage your ears or your system. FAC Punchlab shall not be liable for any loss or damage of whatever nature (direct, indirect, consequential, or other) to your material (software, hardware, or other)

As with all FAC products, the interface has a unique sober look and provides a great user experience. The value of each knob can be monitored at any time. The knobs are very responsive, natural and follow a specific curve according to the parameter type

Preset Management

FAC Punchlab also comes with factory presets to provide you a source of inspiration to satisfy your needs in any situation you might require

The preset button provides common management features: loading, organization, saving, importing and exporting. The left and right arrows allow fast navigation shortcuts among all the presets (factory + user), a short press on the center label provides a detailed list of all the available presets, select the one you want to work with. On the other hand a long touch (hold) provides contextual operation

Review Fac Punchlab

This is marvelous! A timesaver, super intuitive, ready for modern-production-sounding producers and projects!


Tried it on a drum buss, super easy to dial in what I want! The GUI is also easier to see on an iPhone!


Punchlab is another instant winner from FAC. I love how you can stick it on anything and easily manipulate the sound with the chain of amazing effects. The fact that you can reorder the effects and turn stuff on and off, just adds to the flexibility. It’s also the best looking FAC app in my opinion


Great!! A one stop shop!! Gives me real impact on the Drum and Main Bus.
Great job on the presets too, they’re shaped really well


Yeah, it will be a ’no brainer’ for anyone wanting to process sounds, not only drums :)
I particularly love the gain on the input to really trash things up!


Heat with Oxygen Knob?! How cool is that 🫵🏼🤩 ! Sounds really good and offers a lot of sound design possibilities 🙌🏼
