The Japanese D4 has a number of sonic advantages, namely no use of noise reduction and a more stable stereo image. On the other hand, it doesn't sound as crisp as the regular disc and has the peaks clipped more severely. This tutorial will fix that.
- open Audacity in 32 bit mode (default but check in the "quality" settings in preferences)
- import all the songs from the Jap cd and wait for them to parse
- highlight them all
- from EFFECTS, choose "high pass filter" and set the frequency to 20 and the rolloff to 48db then click OK and wait for it to finish
- download this zip file: https://tinyurl.com/expires-Nov-4
- in EFFECTS go to "Equalization" or "Graphic EQ" (depending on which version of Audacity you are using) then "save/manage curves" and choose "import"
- depending on which version of audacity you have, select either the XML (older vsn) or TXT (newer vsn) file you just downloaded "1970 eq" and "open"
- still in the "manage curves" window, scroll down the list of curves and highlight "1970 eq" and then click "OK"
- the audacity equalizer should configure automatically. If it hasn't then select "1970 eq" from the "select curve" dropdown box.
- IN THE LATEST VERSION OF AUDACITY, YOU CAN ALSO APPLY THE ABOVE "1970 eq.txt" USING "Filter Curve EQ" in "EFFECTS"
- Once it has loaded and you've checked it looks like the image below, click OK to apply the eq to all highlighted songs and wait
