Frequently Asked Questions

Getting Started

Will Hush / Hush Pro work on my machine?

All Hush products require macOS 12 (Monterey) or later and are heavily optimized for Apple Silicon. Hush Pro, in particular, officially requires an Apple Silicon Mac, and may not run properly on Intel machines. Before making a purchase, I strongly recommend taking the free trial for a spin, to make sure everything works as expected. For detailed specifications, please refer to the Requirements section of the relevant product page.

How do I activate my license?

Hush Pro is currently DRM-free and doesn’t require activation (iLok or otherwise). After purchasing a license, you’ll receive a download link to a file called HushPro.dmg. Download the package, run the installer, and you’re all set. If you have the free trial installed, Hush Pro will replace it, retaining all of your presets and settings.

If you can’t find the download link, search for an email from Lemon Squeezy, the official payment processor for Hush products. Click the View Order button in the email to find your download link. You can also log in here to access your past orders.

After installation, you can find Hush Pro (both the Mix and Split versions) under the AudioSuite menu in Pro Tools, in either the Noise Reduction or Ian Sampson categories.

Can I install the software on more than one computer?

With a single-user license, you can install Hush and/or Hush Pro on more than one machine, as long as you’re the only person using the plugin. If you need to use it on a shared workstation (e.g. when visiting a mixing stage), that’s fine too — just delete the plugin again when you’re finished, following the uninstallation instructions in the manual. If other people want to use the plugin, they’ll need their own licenses, or seats on a multi-seat license.

How do I get software updates?

Whenever I release an update, you’ll receive an email notification with download instructions. If you completed your purchase via the standard checkout, you can also log in here to download the latest version.

If you purchased Hush on the Mac App Store, you can find updates under the Updates tab in the App Store app, or by following this guide from Apple.


Do you offer educational pricing?

Yes, students and teachers in the field of professional audio are eligible for a 30% discount on all Hush products. Just send me some proof of enrollment (such as a student or faculty ID card) and I’ll respond with a discount code you can use at checkout.

Do you offer upgrade pricing from Hush to Hush Pro?

Yes — if you have the original Hush app, you’re eligible for a $70 discount when purchasing Hush Pro, making the upgrade price $179 rather than $249.

To upgrade, first make sure you have version 1.2 or later of the Hush app. (You can update for free via the Mac App Store.) Launch the app, open the Hush menu, and choose About Hush. You’ll see an 8-letter code beside the copyright notice. To redeem it, enter your code into the “Discount code” field on the Hush Pro checkout page.

How do multi-seat licenses work?

Multi-seat licenses allow you to purchase several licenses for a single organization (such as a studio, mixing stage, or university program). Seats may be allocated to individual users or to shared workstations, whichever makes more sense for your use case. For example, at a university, you might want to install Hush Pro on a dozen machines, shared among multiple students.

If you purchase 5 seats or more, you may also be eligible for volume pricing. For more details, please reach out with a few details about your setup, such as the number of seats you’re interested in purchasing.


Why is Hush Pro rendering silence?

Silent or truncated clips typically mean the plugin has encountered an error. First, make sure you have the latest version installed (1.0.1 or later) and that your system meets the minimum requirements. If Hush Pro displays an error message, follow any trouble-shooting steps, close the plugin, then open it again. If the problem persists, please send me a screenshot of the error, along with your Mac model, macOS version, Pro Tools, and Hush Pro version.


Will you make an AU/VST version?

Likely yes, but it’s easier said than done.

At the moment, Hush Pro includes two AudioSuite plugins (Hush Mix and Hush Split), which run inside Pro Tools. The plugins use random access — they look at the entire audio clip before processing — in order to isolate dialogue as transparently as possible. AudioSuite supports random access out of the box, while real-time formats like AU and VST do not.

With a few modifications, though, I hope to port Hush Pro to these formats in the not-too-distant future, and will make them available as free updates for Hush Pro users, whenever they’re ready.

Will you make a Windows version?

Not anytime soon. Both Hush and Hush Pro are heavily optimized for Apple Silicon Macs, and rely on several Apple technologies (CoreML, Accelerate, and SwiftUI, among others). Porting my software to Windows would require a complete rewrite, including optimization for a variety of PC and GPU hardware. As a solo developer, I don’t have the resources to pull this off just yet, though I haven’t ruled it out.
