01Overview

Tube Bell focuses on the mid-frequencies, the range where much of a mix's body and presence sit. It is built on APNN 2.0, a neural network that Three-Body Technology trained on analog hardware to capture both tonal and dynamic behavior. The plugin includes a drive control for added warmth and is part of the Deep Vintage Suite, a set of hardware simulations the developer describes as offering vintage character with low CPU impact.

Sound and Character of the Tube Bell EQ

Three-Body Technology describes Tube Bell as delivering a smooth and natural sound. The plugin uses APNN 2.0 neural modeling, which the developer says learns from the way hardware changes audio in both waveform and spectrum. Beyond frequency response, the model is intended to reproduce dynamics and the drive behavior of the original hardware.

A drive control adds warmth, so you can push the mid range toward a fuller, more saturated tone or keep it cleaner. The processing sits in the 200 Hz to 5 kHz band, which covers the frequencies most often associated with body and presence in vocals, guitars and synths.

Workflow, Controls and Monitoring Options

Tube Bell includes undo/redo and A/B switching, so you can compare a processed signal against the original without losing your settings. An input/output level meter helps you keep track of gain staging as you work.

For stereo material, LR and MS processing options are available, along with mono mode and phase invert. A GUI re-scaling option lets you adjust the interface size to your screen.
