Tape Pro – Caelum Audio

Tape Pro is a multi-fx tape emulation AUv3 plugin and app that introduces warmth, frequency shaping, modulation, noise and delay. Whether you want to accurately replicate a microcassette tape running at 1.2cm/s, or you want to drive a mastering grade tape machine with strange distortion shapes into a high feedback delay engine, Tape Pro is the plugin for the job.

Saturation
The saturation module is the first part of the signal chain within Tape Pro. It’s very flexible as it isn’t restricted to the traditional sound of tape and can be used to tune into your desired distortion sound. The module has 5 user parameters: Type, Drive, Asymmetry, Hysteresis and Remanence. The types of saturation on offer are: Tape, Digital, Rectify, Half-Rectify, Sine & Smooth.

Response
The response module within Tape Pro models the dynamic frequency response of tape. This can bring warmth, presence, or even jarring qualities to your audio – this is entirely subjective of course! The module has 3 user parameters: Type, Low Pass & High Loss. Tape Pro includes the following impulse responses:
Cassette Type 1, Cassette Type 2, Cassette Type 4, Worn Copi-Delay, New Copi-Delay, Mod Copi-Delay, Master SA812, Master TM15, Microcassette 1.2cm/s, Microcassette 2.4cm/s, Semi-Pro RB77 7.5ips & Semi-Pro RB77 15ips. Tape Pro also includes Minimum Phase (MP) versions of the IRs listed above (not including the copi-delay versions). If you are using Tape Pro in parallel, on a bus or on a send, we recommend that a minimum phase IR is used. (For more information on this please see the explanation in the manual available from our website).

Noise
The Noise module applies real, sampled tape noises to the signal chain. The module has 4 user parameters: Type, Pre/Post Delay, Gain & Crosstalk. The noises included are the same as listed above in the response module.

Wow & Flutter
The Wow and Flutter module emulates the natural irregularities in the physical medium of tape. Wow recreates the low speed fluctuations of tape speed, while Flutter recreates the high speed fluctuations. The modules have 10 parameters in total. Wow: Depth, Sync, Rate, Mod, Sync x2 and Mod Rate. Flutter: Depth, Rate, Mod, Mod Rate.

Delay
The Delay module is an emulation of an analogue tape delay machine. The module has 11 user parameters: Dry, Wet, Time L, Time R, Feedback L, Feedback R, Portamento, Enable, Initial, Sync and Link.

Tape Pro is both a stand-alone application as well as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as GarageBand.
