A track to be released on vinyl should have a certain dynamic in order to sound good and clean on a record. Again, it always depends on the genre and the song itself. Processors that add overtones, such as an exciter that can later make the record sound “shrill”, should also be avoided. Overall, you have to be careful with the high frequencies (S-sounds) of a vinyl master. If no precautions are taken, they can be either “mushy” or too “hot”. These procedures can be identified on the basis of the production of a vinyl. EQ'ING For eq'ing I use a low-cut filter at around 40Hz to minimize possible rumble on the record. The upper frequencies are limited with a Hicut filter. For a vinyl master, 17kHz is a good approach here, as a record cannot always reproduce it true to the original. Try to achieve a very smooth roll-off with different slopes. S-LUTES As already mentioned, S-sounds can be "shrill" noticeable on a record. In order to avoid this, I will describe two approaches: With the help of the bandpass filter of a De-esser, we look for the "sharp" frequency, which can be between 3-10 kHz (depends on the song). Then carefully adjust the de-esser. This should be done with feeling so as not to weaken too much of the particular frequency. It always depends on the song, so it is difficult to give exact values ​​here. This is not only done with Vinylmaster, but it can be particularly important here to ensure a clean sound of the record. For the pros: pulling Okatve over the core frequency at the same time An alternative approach is to use an EQ. We also use it to find the specific frequency and extract it in a narrow band (high Q value), with -1 to 5 dB. The timbre of the entire track is influenced here, but this can be wanted. There is NEVER a perfect solution. MID-SIDE EQ'ING Stereo information in the bass range is not only removed for vinyl masters, but is essential here in order to avoid the needle jumping. It sounds better overall when the bass is more central. For this purpose, the low frequencies are removed from the side signal with a hipass filter. In theory, this can be done with any audio processor that has a mono bass control.
