間違いだらけのスピーカーセッティング【第3回・応用編その1】周波数特性のデジタル補正 フィルター制作編 [REW/Roon]

In this advanced video, Part 1 of "Speaker Settings Full of Mistakes," we'll show you how to create an EQ (equalizer) filter to digitally correct the frequency characteristics measured last time. This video provides detailed instructions on how to automatically create a correction filter using "REW (Room EQ Wizard)," a standard free software for measuring frequency characteristics, to make the characteristics of your listening point closer to flat. It also explains how to export the created filter as an impulse response (WAV file) for use in the music playback software "Roon." We also touch on the limitations of digital correction: while it can suppress peaks in sound pressure, it is difficult to correct dips caused by reflected waves, a complex issue with frequency correction. [Preview of the next video] In the next video, we'll show you how to import the correction file created this time into Roon and actually listen to the corrected sound to verify its effectiveness. 00:00 Opening / This episode's theme: "Digital Frequency Response Correction: Filter Creation" 01:05 Introduction to the free software "REW (Room EQ Wizard)" used for frequency response correction 01:37 Overview of how to create a frequency response correction filter and export data for Roon 02:47 Frequency response of the listening point (3m) targeted for correction 03:44 Explanation of the REW EQ setting screen and basic settings (Target Level, Response Range, etc.) 06:53 Automatically create a correction filter with the Match Response to Target button 07:35 The effectiveness and limitations of digital correction (peaks are corrected, but valleys are difficult to correct due to the influence of reflected waves) 10:44 How to export a correction filter as a Roon file (impulse response/WAV file) 13:12 Summary of this episode and preview of the next one (Installing and listening to correction files) Reference website for creating correction filters https://blog.ipodlab.net/entry-1017/ #audio #audiodesign #speakers ------------------------------------------------------------------------------------------------------------- We've launched a membership program.
