Audio Filter Design Software
Since 2016, Eclipse Audio has been offering a range of software products for equalizing audio systems and creating custom finite impulse response (FIR) filters & complete mixed FIR + IIR filter loudspeaker presets for single and multi-way loudspeakers.
All products share an intuitive workflow that uses imported loudspeaker measurements (from any measurement tool, such as Smaart, Systune, Easera, Klippel & more) as the starting point for filter design.
We offer macOS and Windows versions of all our products, and free demos.
Background
Our founder, Michael John, developed the first product in the range – FIR Designer – after 25+ years experience in loudspeaker and DSP development. It started as a tool for personal use but quickly gained support from loudspeaker designers & installers.
With an increasing number of amplifier & processor brands adding user-accessible FIR functionality to their products, the software makes it easy for users to create their own FIR filters & load them into any FIR-supported product (see a list of FIR-capable brands). Additionally, many loudspeaker manufacturers now use Eclipse Audio software to create & apply proprietary built-in FIR filters in the products they sell.
The original FIR Designer has grown into a range of software options, to cater to the varying requirements of different users.
Ongoing Development
FIR filtering in DSP-driven loudspeakers provides incredible flexibility in loudspeaker design and tuning, and system integration. We’re committed to providing audio professionals with the tools they need.
Creative problem-solving, customer responsiveness & cross-brand collaboration are crucial to the way we develop products.
Feedback informs decisions from product features to pricing. We love to surprise our licensees with a quick turn-around when they tell us about problems that need fixing or have ideas for new features. As a small & flexible business, we consider responsiveness to be one of our strengths.
Collaboration with several leading audio brands is a key part of our development process. We’ve worked with Lake Processing, Powersoft, Linea Research & Rational Acoustics to include time-saving compatibility features, making it even easier for customers who use these brands to develop loudspeaker processing solutions.
Education
We’re committed to sharing our FIR filtering knowledge & helping audio professionals expand their understanding of the applications & benefits of FIR filtering for loudspeakers. Michael John’s Guide to FIR Filtering is a perfect introduction for anyone new to the topic. We’re planning to produce more of our own educational articles in the future, as well as continuing to support other loudspeaker DSP educators (several of whom are using Eclipse Audio software in their training courses & materials).
