Filters are a hugely important tool in the producer’s collection, whether mixing, sound designing or adding interest and variation in an arrangement. On this course from Producertech Senior Tutor Rob Jones, you’ll learn all of the basics, as well as a whole host of techniques for applying both static and dynamic filtering to all sorts of sounds in your mix.

The course begins with an overview of the different ways filters are used, followed by a guide to the main filter types and standard controls. Following this is a demonstration of numerous static filtering applied to all of the sounds in the course project, a laid-back Downtempo groove. Once the basics are covered, Rob progresses things into more advanced territory, introducing different types of filter modulation, with envelopes and LFOs. Again, after going through the theory, he switches back to the course project, to show how different dynamic, modulated filtering can be applied to various sounds, explaining the reasons for doing it in the process.

Other techniques covered include controlling filters with external signals using sidechaining, modulating 3rd party plugins with Max 4 Live tools, working with filter pattern software like Cableguys Shaperbox, and lots more. Examples are once again shown both in the course project, as well as a dedicated module on bass processing.

Enrolling on the course gets you immediate access to the streamed tutorials, plus all the downloadable materials, with accompanying written notes, software projects and samples. Additionally, there’s a course assessment, featuring both written questions and listening exercises, to ensure that the information is sinking in and the ears are being technically trained.

Course Breakdown

Module 1 - Filtering Basics
In this first module, Rob introduces the concept of filtering, by giving a quick overview and demonstration of the wide range of applications. He then takes a more detailed look at filter frequency, resonance and slope, and provides an explanation of the main types of filter, including low-pass, high-pass, band-pass and notch.
Lesson 1 - What are filters and how are they used? 3.46
Lesson 2 - Standard Filter Controls - 8.35
Lesson 3 - Filter Types - 6.12

Module 2 - Basic Filtering Practice
Rob applies filtering to all the individual sounds in the course project, to show the huge part filters play in shaping the frequencies of each instrument and so cleaning up the mix.
Lesson 1 - Project Intro - 3.00
Lesson 2 - Kick Drum Filtering - 8.29
Lesson 3 - Snare and Hat Filtering - 6.37
Lesson 4 - Snare and Hat Filtering - 8.23
Lesson 5 - Guitar, Organ, Marimba and Piano Filtering - 13.02
Lesson 6 - Pluck Arp and Bass Filtering - 4.43

Module 3 - Filter Modulation
A demonstration of how to modulate filters, using the two main modulator types, envelope and LFO. These techniques are shown with a sustained chords phrase, which is transformed into a classic lead and rhythmic pad sequence.

Module 4 - Applied Filtering Modulation Techniques
Rob continues to develop the Downtempo track, by applying a series of dynamic, modulated filtering techniques to the sounds within it, helping to tighten and shape sounds, as well as add extra movement and width.
Lesson 1 - Bass Envelope Modulation - 4.22
Lesson 2 - Percussion and Snare Envelope Mod - 7.39
Lesson 3 - Pluck Arp LFO Mod Stereo Notch Filter - 15.26

Module 5 - Filter Sidechain/External Triggering
A guide to using sidechaining to create filter modulation using external signals, such as drum loops, custom made patterns and even MIDI clips within the DAW. Rob also provides a demonstration of how to use filter sidechaining to create a ducking effect similar to a sidechained compressor.
Lesson 1 - Using External Signals to Trigger a Vocal Filter - 10.58
Lesson 2 - Creating ‘Ducking’ with a Filter - 3.23

Module 6 - Filter Sidechain and Automation Techniques
The final session with the Downtempo project sees Rob using sidechaining and automation to control filter parameters in the arrangement, creating rhythmic patterns and allowing parts to flow and play well with one another.
Lesson 1 - Sidechain Modulation on the Pluck Arp - 5.00
Lesson 2 - Downwards Sidechain Modulation on Organ and Guitar - 09.50
Lesson 3 - Organ and Pluck Arp Automation - 10.05

Module 7 - Bass Processing
A set of lessons dedicated to bass processing, showing 4 different techniques for creating rhythmic filter patterns in the DAW, working with a distorted bass sample accompanied by a Glitch Hop Beat.
Lesson 1 - Drawing Automation - 04.22
Lesson 2 - Recording Automation - 03.46
Lesson 3 - Applying LFO to 3rd Party Plugs - 03.20
Lesson 4 - Using Cableguys ShaperBox - 4.34

Module 8 - Outro
Some final comments from the tutor and advice about where to go next.


Rob Jones

Rob is a classically trained musician, with piano as his primary instrument, and obtained a degree in music and sound recording (the prestigious Tonmeister course) from the University of Surrey. Having honed his skills both at University and in the studios in London where he worked in a technical role, he began releasing music on labels like Lot49, Dead Famous and Erase, under the artist name Anarchy Rice. Rob has been at the forefront of music software training since the very beginning, having kicked things off at Focusrite back in 2006. With both classical music and technical sound qualifications, as well as a wealth of presenting experience, he is ideally suited to the role of an online music trainer, and is 100% dedicated to sharing his knowledge and assisting others with what he believes to be one of the most rewarding things in life - making music!
