Blue Cat's FreqAnalyst Multi is a unique multiple tracks real time spectrum analyzer: it lets you visualize the spectral content of several audio tracks on the same screen with extreme smoothness and high resolution for both time and frequency. It is the ideal solution for mixing: you can use it as a frequency overlap detector and actually see which part of the spectrum every single instrument uses. It is now also possible to easily compare the spectrum of several instances (for EQ matching or response curve measurement) thanks to the new 'Diff' view which displays the difference between several curves.

  • Mono, stereo or mid/side multiple tracks real time spectrum analyzer
  • Unique data sharing technology with multi-core processors support
  • Compute and display the difference between spectra

Blue Cat's FreqAnalyst Pro

Blue Cat's FreqAnalyst Pro is a real time spectrum analyzer with advanced functionalities. It uses the same smooth algorithms as its little brother (Blue Cat's FreqAnalyst free plug-in):
it has been designed to provide extreme smoothness and high resolution for both time and frequency. The frequency analysis can be fine-tuned in details: manage its precision and rate, apply an offset or slope to the measured spectrum. Two thresholding systems are available, and the time response can be changed thanks to the attack and release parameters. Three modes are offered for each channel.

  • Mono, stereo or mid/side real time spectrum analyzer
  • Total control over the analysis parameters, with slope and offset correction
  • Smart interpolation algorithm for extreme display smoothness
  • Spectrum and spectrogram views
  • Animated zoom for all displays

Blue Cat's Liny EQ

Blue Cat's Liny EQ is a 9-band linear phase equalizer. It processes the signal without the usual phase distortion most classical digital EQs produce. Its customizable and wide range of gain (+/- 40 dB per band) makes it suitable for any sound sculpting to subtle final mix equalization task. Additionally, two shapes are available for the filters ("Notch" or "Symmetric"). The Smooth Update mechanism has been included in this plug-in so that you can automate the equalizer in your favorite sequencer or use the MIDI capabilities of your sequencer to control it in real time.

  • Linear phase equalizer
  • Customizable +/- 40 dB range
  • Two different EQ shapes available
  • Automatic gain compensation
  • Very short latency: 2.9ms (128 samples at 44,1 kHz)

Blue Cat's MB-5 Dynamix

Blue Cat's MB-5 Dynamix is an extremely powerful all-in-one multiband dynamics processor: it can be used as a multiband compressor, limiter, gate, expander, wave shaper or all combined at once, on any part of the spectrum. The unique dynamics processing section of the Blue Cat's Dynamix plug-in has been streamlined and integrated in this plug-in to process each one of the 5 bands separately. The plug-in provides unique envelope detection capabilities that let one band trigger the dynamics response on others (internal side-chain).

  • Multiband dynamics processor: compressor, gate, limiter, expander, wave shaper
  • Up to 5 bands, with crossover filters from 6 to 60 dB/Oct for optimal separation
  • Unique envelope routing capability for cross-band dynamics effects
  • Dry/wet control for parallel processing

Blue Cat's MB-7 Mixer

Blue Cat's MB-7 Mixer is a unique plug-in that splits the signal into several frequency bands and lets you mix them as if they were separate tracks. Each band proposes controls that you can find on a mixing console, and more: bypass, mute or solo each band separately to isolate frequencies you want to work on, adjust the gain, the "stereoness" and the position in the stereo field. When manipulating the stereo image, a master mono switch also lets you check mono compatibility. The plug-in also proposes unique linking and grouping options thanks to our multi-instances technology.

  • Multiband mixing console: adjust the levels, panning and "stereoness" of each band
  • Dual Mode: independent left and right or mid and side channels control
  • Multiple instances linking

Blue Cat's Oscilloscope Multi

Blue Cat's Oscilloscope Multi is a unique multiple tracks real time waveform renderer and comparator: it lets you visualize the content of several audio tracks on the same screen and compare them thanks to its X-Y view. The plug-in offers stereo or mid-side channels waveform extraction as well as several synchronization modes. The zooming and precise measurement capabilities let you analyze the waveforms in details, and the XY phase scope view will help you track phase issues within an effect chain or while recording with multiple microphones.

  • Multiple tracks real time oscilloscope
  • Waveform display with loop and flow modes
  • Histogram display
