Instructions for tweaking the Japanese Disc 4
Posted: Tue Oct 26, 2021 1:30 am
Let me start by saying that the rogue Japanese disc 4 with the unadulterated 1969 Get Back is still very much an official release so cannot be uploaded here. But for those of you who have bought the set in question, powerPC has asked me to post this tutorial.
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
- With all tracks still highlighted use "amplify" from EFFECTS and check there is a negative value displayed, then OK. If there is a zero displayed you are not in 32 bit mode so go back to the start.
- after that go through each song in turn and double click on the silent section at the end and delete it
- then under FILE choose "export multiple" and export the tracks in your preferred fdormat and location.
