Old School: Free Analog-Modeled Processor Collection by iDigLabs (macOS)
iDigLabs has released Old School, a free collection of ten analog-modeled processors for macOS that models not just individual units but the interaction between them when chained in series. The suite is available as a direct download from the developer's website with no sign-up required.
What Old School Includes
The collection contains ten processors designed to work together as a hardware-style signal chain:
- Preamp with transformer saturation
- Equalizer with passive-style curves
- Compressor with program-dependent behavior
- Limiter with soft-knee characteristics
- Gate with lookahead detection
- De-esser with frequency-selective reduction
- Exciter adding harmonic content
- Stereo widener with mono compatibility
- Tape saturation emulation
- Output transformer emulation
How the Chain Modeling Works
Old School accounts for transformer loading effects, cable capacitance between stages, and stage-to-stage drive levels so the chain behaves like physical hardware run in series. Each processor reacts to the signal level and impedance presented by the previous stage, creating cumulative coloration that single plugins cannot replicate.
System Requirements & Download
Old School runs on macOS 11 (Big Sur) or later in VST3, AU, and CLAP formats. The download is a single installer package (~180 MB) from the iDigLabs website. All processors are royalty-free for commercial use with no attribution required.
Quick Facts: Old School by iDigLabs is a free macOS-only plugin suite of ten analog-modeled processors with hardware-style chain interaction modeling. Download directly from idiglabs.com in VST3, AU, and CLAP formats.
