Software to measure the acoustics and make better mixing decisions:
Developing an acoustically enhanced recording studio has come a long way in the past 20 years. With the introduction of room acoustics software the user now has identifiable aspects for the rooms acoustics that were never available before, short of hiring an acoustics engineer to aid in the development of the room in question.
The first thing you have to have is a room, a real room. One of the things I see folks do is to get into an area of a basement or the home, often an irregular area with no symmetry at all, and then they attempt to take readings with the room acoustics software. This will never work, not like you require it. You have to have an already established room with hard boundaries to set monitors in, place the microphone and take readings with the room acoustics software. Naturally interpreting the data can be a challenge, so you may want to read this page, in addition to the help files and manuals that comes with your software.
RT60 calculation Wallace C. Sabine reverb time reverberation Sabin … to the time required for the level of a steady sound to decay by 60 dB after the sound has “In 1898, Wallace C. Sabine (Sabin) (1868 – 1919) came up with the reverb time formula, but the article “Collected Papers on Acoustics” appeared in print 1922.
Even today his ingenious formula is unchanged in constant use.”

DIRAC Room Acoustics Software Type 7841 Evaluation Copy
“DIRAC PC software is used for measuring a wide range of room acoustical parameters. Based on the measurement and analysis of impulse responses, DIRAC supports a variety of measurement configurations. For accurate measurements according to the ISO 3382 standard, you can use the internally generated MLS or sweep signals through a loudspeaker sound source. “
C.A.R.A. – Computer Aided Room Acoustics
“The surfaces of room walls and furnishings (in CARA modelled by “3D Objects”) may consist of different materials with different acoustic properties (sound absorption coefficients)”
Room Mode Calculator
EASERA is an all-in-one software package for acoustic and electronic measurements.
“EASERA stands for Electronic and Acoustic System Evaluation and Response Analysis. Basically it is a PC/Windows based software for acoustic and electronic measurements utilizing any built-in or external soundcard.”
Room EQ Wizard 4.11 (REW)
“Room EQ Wizard is a Java application for measuring and correcting room resonances. It includes tools for generating test signals, measuring SPL and frequency responses and automatically adjusting the settings of parametric equalizers to cancel the effects of room modes.”
