REW Measurement Guide for Home Theaters252

Room EQ Wizard (REW) is a free software program that allows you to measure and analyze the acoustic response of your home theater system. This information can be used to improve the sound quality of your system by identifying and correcting problems such as room modes, speaker placement issues, and other acoustic anomalies.

Getting Started

To use REW, you will need the following equipment:* A computer with a sound card
* A microphone
* A set of speakers
* A subwoofer (optional)

Once you have gathered your equipment, you can download REW from the following website:

Once you have downloaded and installed REW, you can launch the program and begin setting it up. The first step is to select your sound card from the "Device" dropdown menu. Next, you need to select the input channel that your microphone is connected to. Finally, you need to set the sample rate and bit depth. The default settings are usually fine, but you can experiment with different settings to see what works best for your system.

Measuring Your Room

Once you have set up REW, you can begin measuring your room. The first step is to place your microphone in the listening position. You should sit in your chair and place the microphone at ear level, pointing towards the speakers. Once you have placed the microphone, you can click on the "Measure" button in REW. REW will then play a series of test tones and measure the response of your room.

REW will display the results of your measurement in a graph. The graph will show the frequency response of your room, as well as the phase response. The frequency response will tell you how loud your speakers are at different frequencies. The phase response will tell you how in-phase your speakers are at different frequencies. Ideally, your speakers should be in-phase at all frequencies.

Analyzing Your Measurements

Once you have measured your room, you can begin analyzing the results. The first thing you should look for is any major peaks or dips in the frequency response. These peaks and dips can be caused by room modes or other acoustic problems. You can use REW to identify the source of these problems and then take steps to correct them.

In addition to the frequency response, you should also look at the phase response. The phase response can tell you how in-phase your speakers are at different frequencies. Ideally, your speakers should be in-phase at all frequencies. If your speakers are out of phase, you can use REW to adjust the phase of your speakers so that they are in-phase.

Improving Your Sound Quality

Once you have analyzed your measurements, you can begin making changes to your system to improve the sound quality. There are a number of things you can do to improve the sound quality of your system, such as:* Adjusting the placement of your speakers
* Adjusting the level of your subwoofer
* Adding acoustic treatment to your room

REW can help you to make all of these changes. REW can help you to identify the source of acoustic problems in your room and then make recommendations on how to correct them. REW can also help you to adjust the level of your subwoofer and to add acoustic treatment to your room.

Conclusion

REW is a powerful tool that can help you to improve the sound quality of your home theater system. REW can help you to identify and correct acoustic problems in your room, and it can also help you to make adjustments to your system to improve the sound quality. If you are serious about improving the sound quality of your home theater system, then I highly recommend that you use REW.
