Flux have released their revised Studio Session Pack, which is available for a limited time at an introductory price of $149. More from the manufacturer:

Today it’s a common thing to record and produce music with a Project Studio setup, and as we think there should never have to be any compromise to the sound quality we introduce the Studio Session Pack, offering some of our finest recording and mixing tools, the Flux:: Essentials, in a comprehensive bundle for the Project Studio.

The Studio Session Pack was created specifically with music production and project studios in mind, and the Studio Session version of the software included in the bundle have been revised to meet these requirements and differs slightly from the standard versions.

Pure Compressor offers everything you would expect from a compressor, ranging from clean transparent subtle processing to classic heavy pumping.

In addition to the common standard compressor controls for attack, release, threshold and ratio, Pure Compressor gives you total control of the fundamental characteristics and essential dynamics profile used for the compression, with hands on controls for every parameter, all in order to achieve the ultimate dynamics processing in every situation.

Pure Expander is a powerful versatile processor capable of anything from mild expansion to hard noise gating, perfectly suited for soft downward expansion to clean up spillage on (live) recordings, remove noise, reverberation and leakage from drum sessions.
 
Pure Expander is designed to automatically reduce the gain below the threshold, providing full control over the general behavior, and of the performance characteristics and how it responds to the incoming audio signal.

Pure Limiter makes transparent limiting easy; a dramatic increase of the average audio level can now be accomplished without damaging the perceived audio quality, with the exquisite proprietary Flux:: technology generating a release envelope assuring that no artifacts on the processed sound are produced.
 
Unless you use it as a special effect, Pure Limiter v3 should always be in the very last stage of your audio processing chain.

Epure is a state-of-the-art five-band equalizer designed to provide the absolute finest audio quality within the domain of digital audio processing, carefully tuned with Flux:: proprietary State-Space technology, to preserve the optimal signal to noise ratio independent of the parameter settings, preventing the signal from deteriorating when the gain is reduced.
 
Epure is a powerful go-to processor for your day-to-day session work, as well as an efficient sharp-edged surgical precision tool for the most demanding equalizing and filtering tasks conceivable.

Syrah is a new generation dynamics processor using real-time dynamic detection and level dependent processing, to provide adaptive dynamic capabilities, which mean that Syrah is always trying to adapt its processing to the music and to the beat of the material.
 
Using parts of our exquisite ‘BitterSweet’ technology, our new adaptive-dynamics technology, and our well-recognized level independent dynamics processing, Syrah is well suited as a creative versatile processor for recording and mixing, as well as for delicate and demanding mastering tasks.

BitterSweet Pro is built around a new improved design of the algorithm found in our acclaimed freeware transient processor, BitterSweet, used by hundreds of thousands of users all over the world, and the approach we had when designing BitterSweet Pro was to make it just as easy and straightforward to use.
 
One of the main features of BitterSweet Pro is the Frequency Dependent Transient Processing, providing the ability to process only a certain part of the frequency spectrum making it act just like a dynamic equalizer driven by Transients and/or Sustain.

Verb Session based on the same supreme technology used in the acclaimed Ircam Verb, is tailored for simplicity with a fast paced workflow well-suited for situations where the perfect result has to be achieved within seconds.

Pure Analyzer is a stand-alone application providing a comprehensive range of analyzer options for any imaginable audio analysis and measurement applications.
 
A SampleGrabber plug-in available in all standard plug-in formats, inserted into the insert chain on any DAW or Digital Mixing Console supporting standard plug-ins, is used to grab the audio samples and send the signal through the network to the Pure Analyzer stand-alone app for instant real-time analysis.
 
The Studio Session version of Pure Analyzer has no hardware I/O support and can not be expanded with the Pure Analyzer add-on options.

*The Studio Session Pack AAX Native/AudioSuite plug-ins supports 32 bit in Pro Tools 10.3.5 and 64 bit in Pro Tools 11.
