The disclosure, again and always: The Compression Code is my course. Matthew Weiss doesn’t know I’m writing this. I think his course is good, I’ve recommended his teaching to students, and if this page convinces you his course fits you better, that’s the page working as intended. An informed buyer who picks the right course is worth more to everyone than a mismatched customer with a refund request.
At a glance
The Compression Code (mine): $49 one-time, lifetime access. Nine lessons plus a capstone, built around a by-ear decision framework: what attack and release actually do, how to hear gain reduction rather than watch the meter, when compression is the wrong tool, and the signature techniques I use on records. It’s designed to be worked alongside the free interactive tools on this site. 30-day money-back guarantee.
Mixing With Compression (Matthew Weiss): about $67, listed down from $97. Over four hours of HD video in which Weiss, a credited engineer across hip-hop, R&B and pop, applies compression to real drums, vocals and basslines. Includes bonus sample content and access to his community. Over 2,100 students enrolled. 30-day money-back guarantee.
Both are one-time purchases. Neither is a subscription. On price, guarantee and honesty of intent, they’re effectively tied. The real difference is philosophy.
The philosophical difference
Weiss’s course is fundamentally demonstration: watch an excellent engineer make real decisions on real multitracks, with commentary. The bet is that enough hours of over-the-shoulder observation transfers the instincts.
Mine is fundamentally training: a sequence that builds the listening skill directly, so the decisions become yours. The bet is that compression is like an instrument, and you learn instruments by playing, not by watching concerts.
Neither bet is wrong; they suit different learners and different stages. Watching demonstration content when you can’t yet hear what the demonstrator is responding to is how people end up copying settings that don’t work on their own mixes, which is the exact failure mode I built my course against. But once your ears work, watching a master apply the skill in your genre is rocket fuel. That’s the honest sequencing: train first, then study application.
Where Mixing With Compression wins
Genre application, especially rhythmic music. If you make hip-hop, R&B or pop, Weiss’s examples land directly on your material, and his treatment of punch, density and rhythm on those sources is the best part of the course. More raw video hours. A community, if that matters to you. And Weiss himself: he’s a clear, experienced teacher and you’re hearing judgement formed on credited records.
Where The Compression Code wins
Price, at $49 versus $67. Structure: nine lessons in a deliberate order, each building on the last, rather than a body of video to absorb. Ear training as the explicit goal: every lesson tells you exactly what to listen for, then has you prove it on your own sessions rather than watch someone else’s. Integration with free practice equipment: the Visualiser, Calculator and Troubleshooter are the lab bench for the course. And genre neutrality: the framework is the same whether you mix metal, folk or techno, which matters if you don’t make rhythmic urban music.
So which one?
If you can already hear compression working and want to sharpen application in hip-hop, R&B or pop: Weiss, without hesitation.
If you know the theory but still guess at the knobs, if you’ve watched plenty of tutorials and your mixes haven’t changed, or if budget matters: The Compression Code, because your bottleneck is the ear, not the examples.
If you’re serious enough to buy both, do them in that order: train the ear first, study application second. And if you’re not sure you need a course at all, start with the free compression tools and the wider course comparison, then come back when you know what’s missing.
