Pros & Cons
Pros
Applies equalization and volume boosting across all macOS applications, as highlighted in the key features, allowing users to enhance audio from any source.
Uses a user-space driver based on Apple's framework, making it more stable and secure than kernel-level alternatives like SoundFlower, as noted in the Technology section.
Automatically equalizes headphones using frequency response data from the AutoEQ project, improving audio quality for specific models without manual tuning.
Offers multiple EQ modes from basic 3-band to unlimited customizable bands, catering to both casual listeners and audio enthusiasts with varying needs.
Cons
The public repository only contains v1.3.2 without Pro features, with newer releases kept private, limiting transparency and community development, as stated in the README notice.
Advanced capabilities like per-app volume mixing, spatial audio, and AudioUnit hosting require a Pro subscription, restricting free users from essential tools.
The web-based UI is hosted remotely, which can introduce latency, offline usability issues, or privacy concerns, as mentioned in the Technology section.
