This article aims to be a beginner level explanation for how digital audio filters work. Most discussion about filtering involves university-level math, making it inaccessible to most learners. I will explain everything from first principles and also include lots of good links for further reading. If all goes well, this should be accessible to anyone with some high school Algebra knowledge. Here is a roadmap of the article. The first section talks about how we can make a low-pass filter by taking a […] - [Add Depth to your Tracks with Vocal Pads](https://www.davisynth.com/add-depth-to-your-tracks-with-vocal-pads/): Vocals fill an important gap in the mid-range of the audio spectrum that is often unoccupied by other instruments in the mix. This is amazing for artists that can sing, but it leaves the rest of us struggling to fill the missing piece in our tracks. Platforms like Splice are full of short vocal samples that sound great but are not long enough to fill an entire song alone. Luckily we can stretch the use of these vocals through clever sampling and remixing. One of my favorite methods of vocal editing is to turn them into pads that sit in […] - [Register Your Product](https://www.davisynth.com/register-your-product/): To register, follow the steps below: ## Pages - [New Customer Service Policy](https://www.davisynth.com/new-customer-service-policy/): Hello Davisynth community, I work on Davisynth as a weekend project while pursuing my PhD in Electrical Engineering.  Making plugins is extremely rewarding, but as the number of customers has grown, most of my time has been spent on customer service and I am now spread too thin. This has significantly slowed down development for new features. It has also led to me not being able to run promotional discounts due to the huge volume of customer service work that comes with them. As a result: Today I am taking Davisynth in a new direction. All Davisynth software is now […] - [Terms of Service](https://www.davisynth.com/terms-of-service/): *Last Updated: 9/18/2025* Terms of Service for Davisynth Audio Software Legal Disclaimer These Terms of Service (“Terms”) govern your access to and use of Davisynth software (the “Software”), website, and related services.
