Hello JRiver forum, I wrote a book with the above title using JRiver, Acourate, and REW: https://www.amazon.com/dp/B01FURPS40

To view the Table of Contents and read the first few chapters, simply click on the cover image "Look inside."

It is also available worldwide at the corresponding country's Amazon site.

Archimago wrote a thought provoking article on the Importance of Sonic Accuracy and the Audiophile which includes a “hands-on” review of my book:  http://archimago.blogspot.ca/2016/05/updated-room-measurements-musings-on.html

I have included the book description below.

Regards, Mitch


This eBook provides the audio enthusiast with an easy-to-follow step-by-step guide for designing a custom digital filter that corrects the frequency and timing response of your loudspeakers in your listening environment so that the music arriving at your ears matches as closely as possible to the content on the recording.

Industry guidelines, spanning over 40 years of evolution, are referenced throughout the eBook, providing the recommended target responses for accurate sound reproduction. Correcting the measured response to known target responses is, in effect, matching the acoustic output signal arriving at your ears to the digital audio stored in a media file. The target responses can also be tailored to your own preferences.

The chapter on the acoustics and psychoacoustics of room correction explains why we hear what we hear in small-room acoustics and what our ears care about most when it comes to accurate sound reproduction. There are individual chapters on industry target responses for frequency and step response, group delay, energy time curve, reverb time, polar response and interaural coherence coefficient (i.e., imaging).

Advanced sections of the eBook show you how to design and implement digital crossovers, driver linearization, and driver time alignment; how to compensate for brickwall antialiasing filters; and how to use the Beamforming quasi-anechoic measurement technique. All of these sections are designed to incrementally improve your sound reproduction system’s accuracy.

The last section of the eBook shows you how to perform loopback measurements to verify the design and operation of your digital correction filter, not only at the listening position, but across a wide listening area as well.

Whether your sound reproduction system is a computer desktop speaker system, stereo audiophile system, home theater multi-channel system, mains and sub-woofer system, DIY audio system, or car sound system, the results are audible, measurable, and repeatable.

To benefit the most from this step-by-step guide, you will require a computer, a calibrated measurement microphone, an Analog to Digital (ADC)/Digital to Analog (DAC) converter, and two commercial software packages: Acourate DSP Audio Toolbox and JRiver Media Center. This eBook contains several color-coded images, so viewing on a color screen is required.

With over 260 color screen captures of the software in action, plus 200 links to industry reference material and knowledge, this eBook is the definitive guide to Accurate Sound Reproduction Using Digital Signal Processing (DSP).

Neat, I just grabbed a copy.  I look forward to working through it

For those that don't know, Mitchco has posted several very informative articles on the subject on sites like Computer Audiophile, and seems to know this stuff inside-and-out.
It's sure to be a very detailed and well-researched book.
Just grabbed a copy myself too.

I hope folks don't mind me posting a link to another site. I used Audiolense to optimise my speakers by
- develop a linear phase digital XO for biamping.
- time align the drivers.
- smooth the frequency response using a linear phase target.
- use "room correction" to reduce non-minimum phase low frequency room reflections (i.e. reduce group delay).
- use "partial correction" for constant directivity waveguide equalization, but partial time domain correction.

JRiver features used: convolution engine, internal digital volume control, loudness control and volume protection. Really happy with the resulting sound quality.
