ScopeFIR

ScopeFIR is a neat tool for sound editing pros and audiophiles who want to create their own digital filters. If you're looking to design Finite Impulse Response (FIR) filters, this app has got you covered! It’s built to help you come up with custom audio filters that fit your style, offering a solid range of predefined filters and coefficients to help you nail that perfect impulse response.

Easy-to-Use Interface

One cool thing about ScopeFIR is its simple interface packed with awesome frequency response adjustment tools. You can easily input the number of taps you want, set up the grid structure, and enter details like the passband upper frequency or stopband attenuation. It’s pretty straightforward!

Preview Your Designs

Once you've put in your preferred values, just hit the “Design” button. You’ll get a preview of the signal waveform based on your settings! The app even gives you a dual display so you can see both the inphase filter frequency response and the impulse response at once. A little background knowledge on FIR will help, but it’s not totally necessary.

User Controls

You also have control over sampling frequency and can set a specific minimum audio level. Most adjustments are done through input fields, which is nice but could be better with some sliders or knobs for easier handling.

Customization Galore

This app supports multiple coefficients, so you can tweak them however you like! Plus, exporting options are available too—you can save your coefficients in text, HTML, ASM, or binary formats. Although it has loads of signal adjustments available, keep in mind that its settings menu might feel a bit minimal if you're an experienced user.

The Perfect Tool for Custom Filters

If you love creating custom FIR filters, ScopeFIR could be just what you need! With its basic interface and numerous numerical entry tools for adjusting signal waveforms, it's designed to boost your editing flexibility. Plus, you'll have access to a library of sampling frequencies and useful filters.
