Blue Cat’s Freeware Plug-ins Pack II gathers eight of the company’s free audio tools into one streamlined bundle, offering a broad mix of creative effects, mixing utilities, guitar amp simulation and real-time analysis.
Designed for macOS and Windows systems, the pack supports VST, VST3, AU and AAX formats, making it compatible with virtually every modern DAW.
There’s no dongle, no mandatory registration and no hidden paywalls. These are fully functional freeware plugins built on the same engine and interface philosophy as Blue Cat Audio’s commercial releases.
Whether you’re starting out or adding lightweight tools to an existing setup, this pack provides a solid and reliable foundation.
The bundle contains eight plugins that span both creative processing and essential studio functions:
Each plugin addresses a different part of the production chain, from tone shaping and stereo movement to spectrum monitoring and network routing.
The modulation section of the pack delivers three vintage-inspired processors: Chorus, Flanger and Phaser.
Blue Cat’s Chorus offers smooth ensemble-style thickening and deeper modulation textures. It can add width to guitars, synth pads and vocals or push into more dramatic, swirling territory.
Blue Cat’s Flanger recreates the classic jet-style sweep popular in the 70s and 80s. From subtle movement on drums to aggressive, alien-style effects on vocals and synths, it provides a broad modulation range.
Blue Cat’s Phaser is modeled after vintage analog circuits while benefiting from modern digital precision. It works particularly well on guitars, electric pianos and rhythmic elements that benefit from phase-based movement.
Together, these three effects cover most traditional modulation needs without introducing unnecessary complexity.
For mixing and tone shaping, the bundle includes Blue Cat’s Triple EQ, a semi-parametric 3-band equalizer that can behave like a single customizable filter. It’s lightweight and responsive, making it ideal for quick corrective adjustments or subtle tonal shaping.
The Blue Cat’s Gain Suite expands on simple gain control by offering mono, stereo and mid/side versions. One of its standout features is instance linking, allowing multiple instances across different tracks to be controlled from a single interface.
This is particularly useful when balancing layered instruments, managing bus levels or performing coordinated adjustments across grouped tracks.
The Gain Suite also supports full MIDI control and automation, making it adaptable for live performance or complex DAW routing setups.
Accurate visual feedback is essential in mixing and mastering, and Blue Cat’s FreqAnalyst provides real-time spectrum analysis. It allows users to monitor frequency distribution across the audio spectrum, helping identify masking issues, harsh peaks or low-end buildup.
FreqAnalyst is especially useful when paired with Triple EQ or Gain Suite, giving engineers both visual and audible feedback during decision-making.
Blue Cat’s Free Amp delivers three amp models created using the company’s Destructor amp modeling engine. While streamlined compared to premium amp suites, it provides usable clean, crunch and driven tones suitable for demos, tracking sessions and lightweight productions.
For guitarists who need a fast, no-frills solution inside their DAW, Free Amp offers solid tonal flexibility without taxing system resources.
One of the more unique tools in the pack is Blue Cat’s Freeceiver. This plugin and standalone application can receive audio or MIDI streams sent over a network from Blue Cat’s Connector and Fader Hub.
In multi-computer setups or collaborative environments, Freeceiver allows real-time audio and MIDI transfer between systems. For producers running separate machines for processing or live setups, this functionality adds a layer of flexibility rarely seen in freeware bundles.
Blue Cat has updated the pack to support modern systems, including:
The plugins run on macOS (Intel or Apple Silicon, OS X 10.9 or newer) and Windows (Vista or newer, SSE2-enabled processors). Formats include VST, VST3, AU and AAX, covering nearly all professional DAWs.
Yes. All eight plugins are completely free with no hardware dongle, subscription or forced newsletter signup required.
Yes. While streamlined, these tools are stable and reliable enough for professional mixing and tracking tasks.
It’s a simplified solution rather than a full modeling suite, but it provides practical tones for everyday use.
Yes. Its mid/side processing and instance linking make it suitable for stereo balancing and precise level control.
Freeceiver enables real-time audio and MIDI transfer across networked systems, useful in advanced or multi-machine setups.
