RP = ctypes.windll.LoadLibrary(r"C:\REFPROP\refprop.dll")

: It can be accessed through a graphical user interface (GUI), linked to Excel via an Add-In , or called from custom applications via FORTRAN subroutines and a DLL. Core Features of Version 9.1 REFPROP Documentation - Thermodynamics Research Center

NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP): Version 9.0 Authors: Lemmon, E.W., Huber, M.L., McLinden, M.O.

One of the most requested features in earlier versions was better transport property predictions. REFPROP 9 incorporated the latest correlation models for the viscosity and thermal conductivity of refrigerant mixtures, including the effect of critical enhancement (the anomalous increase in properties near the critical point).

DAW Plugin & iOS App

SpectroDraw started as a web app, but soon, you’ll be able to use it anywhere. I am currently developing a VST Plugin of SpectroDraw, projected to be finished by the end of April. I also plan to create an iOS app in the future.

Our Mission

Our mission is to make sound design as natural and creative as drawing on a canvas, turning audio editing into an intuitive, visual experience accessible to everyone. Paint frequencies, sculpt harmonics, and transform audio into creative ideas fast.

We believe audio editing should be visual and playful for students learning audio concepts and sound designers creating effects. Our goal is to allow any sound imaginable to be drawn on the spectrogram.
