The TDR Prism frequency analyzer is free to download at the Tokyo Dawn Records website. The plugin is available for Windows and macOS, and the company describes it as a “modern frequency analyzer with a focus on human audio perception.”
Tokyo Dawn Records has provided a very easy install process, as you can just click download and get the plugin without needing to provide an email address.
The TDR Prism is designed to be easy to use and configurable, as well as to provide “precise insight into the spectral properties of a signal.”
The analyzer has a range of spectral weighting/tilting methods as well as a real-time indication of auditory masking and peak/RMS smoothing options.
The plugin is able to visualize and compare the spectrums of different sources. This is possible not only for audio files but also for regular and sidechain inputs, as well as other instances of Prism.
Tokyo Dawn Records has also included automatic marker lines, screen magnification, and tone generator options to assist with inspecting audio signals.
The plugin is designed to be visually appealing and to provide high-precision plotting, and looking at the interface, it appears the company has achieved these goals.
The user interface is also fully resizable and includes fullscreen support.
The TDR Prism is fully featured and Tokyo Dawn Records doesn’t provide a bigger, paid version – this is the only dedicated spectrum analyzer in their lineup of plugins.
Tokyo Dawn Records has made the plugin available for Windows Vista or above and Mac OS X 10.9 or above.
The TDR Prism is a new release from the company, which at the same time released the TDR Special Filters Bundle. The four-plugin bundle retails for €80.00/$80.00.
Currently, you can get the bundle cheaper, though, as Tokyo Dawn Records is currently running the No Brainer sale, which offers 40% off all plugins in their range. The sale ends in six days.
As you can see on the Tokyo Dawn Records product page, in addition to their paid lineup, the company also provides a total of five free plugins.
Apart from the TDR Prism, the other free plugins from the company are the TDR Molotok (compressor), TDR Nova (dynamic parallel equalizer), TDR Kotelnikov (wideband dynamic range controller), and TDR Vos SlickEQ (mixing/mastering equalizer).
