Vinyl can be cut at a higher digital sampling rates than finished cd’s can provide. If the project was originally recorded at, for example, a 96K sampling rate with 24 Bit depth, the cutting engineer can use those higher resolution digital files to cut the vinyl master. If you’re planning on making a record, it’s worth mentioning to your mastering engineer and getting his or her take on the best way to prepare masters. Please have your engineer get in touch if there are any questions.

High resolution uncompressed audio files such as .WAV or .AIFF files are recommended.
We can use CD digital masters to cut records without any issues in most cases, although heavy limiting can affect the ability to produce a loud vinyl master. 

It’s generally a good idea to create a separate master explicitly for vinyl as the hard final limiting that CD and digital masters go through is not ideal for vinyl mastering and can affect how the project is cut.

It is normal for the vinyl version to have less hard limiting and perhaps a slightly different EQ curve. Please discuss with your mastering engineer our give us a call to discuss in greater detail.
