New 'FIR Designer M' Perpetual License Offers Alternative To Ongoing Subscription
June 17, 2025
FIR Designer M, Eclipse Audio’s multi-channel custom DSP design software, is now available to buy as a perpetual (one-time-payment) license. Previously, purchases of FIR Designer M were subscription-only, requiring an annual recurring payment to stay active.
“The single-channel version of the software (FIR Designer) has been available as either a subscription or perpetual license for a few years”, said Michael John, Lead Developer at Eclipse Audio. “We’re pleased FIR Designer M users now have the same choice of license options”.
A perpetual license of FIR Designer M allows the software to be used indefinitely with no additional payments beyond the initial one. The feature set is ‘frozen’ at the time of purchase, with no access to any updates or new features (except for bug fixes). Alternatively, a subscription license of FIR Designer M requires an annual recurring payment to stay active. The feature set expands over time, with license holders receiving ongoing free updates to the latest version, including all new features & improvements.
“Our development efforts continue to be focused on regularly updating FIR Designer M to expand & improve functionality”, said John. “So a subscription license is still the best option for users who want access to the latest features and guaranteed compatibility with future operating systems. But the perpetual license provides an option for users who just aren’t fans of having an ongoing subscription payment!”
