I would like to share two articles about reading phase response and FIR filter correction.
Understanding Different Views and Thoughts of Phase Response Curves.
I am in the final stages of producing a 3-way pair of stereo loudspeakers which have a flat baffle. I want to try and use the new acoustic reference feature in REW to allow me to accurately measure the impulse response and phase of each driver at the microphone reference point (1m...
A lot of people are using MiniDSP as a cost effective method to create EQ. They can compensate room effect or loudspeaker's linearities. I have been answering a lot of questions about the process of creating FIR filters and I'd like to share two articles about FIR filters...
This is a tutorial explaining how to configure a Windows PC to do all filtering, equalization and phase linearization:
Windows PC as a FIR Audio Processor
Slightly simplified workflow:
Media player --> WDM Audio --> Hi-Fi Cable & ASIO Bridge --> ASIO4ALL --> VSTHost & ConvolverVST --> USB audio...
Web based audio tools: Brutefir online (router), Convolver
Hi, I've just coded a simple page to make real time audio convolution and also offline convolution to download the files (working with chrome and firefox not tested in others). I hope it will be usefull:
Recently I tried the demo of Dirac live and got really good results. The Dirac filter didn't affect the overall sound of the speakers, but the imaging improved quite a bit. The stage was more clearly defined, and instruments better separated.
So I thought I'd try and see whether...
I want to introduce you to my recent development - software crossover for offline processing of the SACD DSD streams.
Its core based on a FIR filter and provides direct filtering for delta-sigma streams, without any intermediate conversion into the PCM.
Stereo DSD stream (inside a...
After obtaining the following EQ filters with REW
Filter 1: ON PK Fc 41.5 Hz Gain -5.8 dB Q 12.22
Filter 2: ON PK Fc 47.2 Hz Gain 1.3 dB Q 7.63
Filter 3: ON PK Fc 57.0 Hz Gain -5.7 dB Q 10.31
Filter 4: ON PK Fc 63.9 Hz Gain -3.1 dB Q...
As the title suggest i would like to use REW to make a few measurements of my room and make a few corrections. These corrections should then end up as a FIR that I can use with a convolver like jconvolver.
I'm pretty much stuck at the last part - getting the nice filter out of...
is there any possibility to create a compensating FIR filter with a predefined lenght (nr of taps or max latency, or lowest frequency corner for linear phase) with REW?
I mean a plain wav for convolver and/or a list of coefficients for DSP programing...
If not, is it than planed? or...
