Persistent Series

Persistent Series is a free plugin bundle designed to help all artists create music and lessen their financial burden. 

Whether you are a beginner or a professional, this project aims to lower cost barriers, support creative freedom, and allow everyone to focus solely on making music in a professional audio production environment.

Persistent Q

Persistent Q is a precision equalizer designed for both mixing and mastering applications. It can handle a wide range of tasks, from basic tonal balancing and problem-frequency removal to creating space between vocals and instruments, as well as making subtle corrections on the master bus.


Core filter types such as Peaking, Shelf, and Pass filters operate in an intuitive manner, prioritizing natural and dependable frequency responses that professionals can trust in real-world production environments. With a wide Q setting, overall tonal shaping can be performed smoothly and musically, while narrow Q values enable precise control of resonances and problematic frequencies. The Gain, Frequency, and Q parameters are designed for fast and efficient adjustment while maintaining a stable and consistent sound.

Persistent C

Persistent C is a versatile compressor designed for use on individual tracks, buses, and master channels alike.


With controls for Input, Output, MakeUp, Mix, and Range, it allows for precise adjustment of compression intensity and final output level. Processing modes including Stereo, Left, Right, Mid, and Side support, not only conventional stereo compression, but also advanced mid/side-based spatial shaping and control.


From transparent level stabilization in mastering applications to adding punch, energy, and consistency to drums and bass in a mix. Persistent C adapts naturally to a wide variety of production tasks while maintaining musical balance and clarity.

Persistent R

Persistent R is designed to handle everything from individual track processing to the subtle spatial enhancement often required on buses and near-master applications.


With dedicated controls for Dry/Wet balance, Input/Output Gain, Width, Damp, Ducking, and Post EQ, it allows reverb to sit naturally within a mix without introducing excessive muddiness or masking important foreground elements.


Persistent R can add natural depth and dimension to vocals, enhance the sense of space and post-transient ambience on drums, and create a wide, musical atmosphere for synths and pads, making it a flexible tool for both mixing and finishing stages of production.

Persistent Saturator

The Persistent Saturator is designed for both mixing and mastering applications.


In mixing, it allows for precise enhancement of an individual source’s character, whether adding presence to vocals, density to bass, attack to drums, or texture to guitars. In mastering, it can introduce subtle harmonic richness and energy to selected frequency ranges without dramatically altering the overall tonal balance, helping improve the polish, impact, and translation of a track.


Rather than simply adding coloration, Persistent Saturator is built to apply the right amount of drive exactly where it is needed within the mix, providing controlled harmonic enhancement while preserving musical balance and clarity.

Persistent SI

Persistent SI is a stereo imager designed for both mixing and mastering applications.


It can be used on individual tracks or buses to refine the spatial balance of specific frequency ranges, while also serving as a powerful tool in the master chain for achieving a more controlled and cohesive Mid/Side image across an entire mix.


By keeping low frequencies firmly centered, managing the density of the midrange, and naturally expanding the openness of the high frequencies, Persistent SI enhances the depth, width, and translation of the final mix, helping it remain balanced and consistent across a wide range of playback systems.

Persistent L

Persistent L is designed for both mixing and mastering applications. During mixing, it can be used to control transient peaks on vocals, drum buses, synths, and subgroups. In mastering, it provides reliable management of final loudness and True Peak Ceiling, ensuring consistent and controlled output for modern distribution platforms.


The combination of Style, Look Ahead, Attack, and Release controls allows it to handle everything from fast and aggressive peak catching to smooth and transparent master limiting, making it suitable for a wide range of production workflows.


The Transient Link and the Release Link offer additional controls over the stereo image behavior and dynamic movement, helping preserve focus, balance, and musical integrity even during heavy limiting. The result is a limiter capable of delivering competitive loudness while maintaining clarity, stability, and the core character of the mix.
