VINYL MASTERING
(For Vinyl prices, templates and quotes, click here)

For best results, please submit the highest resolution audio master files possible—
as high as 24 bit/192 kHz but at least 16 bit/44.1 kHz.

Please upload WAV or AIFF files only (no MP3 files).

Once you place your order, ask your account rep for our upload instructions,
or you can send the files in on disc.

MAXIMUM TIMES PER SIDE

If you exceed the maximum time suggested for a record side, it can affect the quality of the audio. This is because distortion and high frequency loss become an issue as you near the center of the record. The longer the record, the more program is packed into the inner dimensions of the record. Also, longer running times will result in a quieter record, which will make the noise floor of the vinyl more apparent.

SIZE SPEED OPTIMUM TIME MAXIMUM TIME*
12" 45 rpm 12 minutes 15 minutes
12" 33 rpm 17 minutes 22 minutes
       
10" 45 rpm 7 minutes 9 minutes
10" 33 rpm 11 minutes 15 minutes
       
7" 45 rpm 3 minutes 4 minutes
7" 33 rpm 5 minutes 6 minutes

*Longer times may compromise levels and/or EQ.


MASTERING TIPS

Please follow these mastering guidelines for best results:

• All bass frequencies should be centered (below 150 Hz). 
Phase issues in the bass frequencies can cause a collapse of the groove, causing a skip.

• Tame sibilance. Too much sibilance will cause distortion on playback. This should be addressed 
at the mix level for best results. Additional de‐essing during the pre‐mastering stage and cutting process may be possible.  

• Avoid excessive high frequencies. Excessive frequencies above 10 kHz can cause distortion. 

• Try to avoid using psycho acoustic processors to an excessive degree.  

• Do not "clip" waveforms. This technique is often used in cd mastering to achieve a hot level, 
and usually causes distortion when cut. If a re‐cut is requested on a record cut with clipped 
audio, it will be fully billable. 

• Avoid too much limiting. Too much brick wall limiting can cause distortion in the cut. Re‐cuts 
requested due to distortion on material that has been excessively brick walled will incur 
additional costs if not resolved before manufacturing. 

• A distorted master will likely sound more distorted when transferred to vinyl. Watch the distortion on the mix. 
 
• Keep in mind that due to the limitations of vinyl, high frequencies are reduced the further you get towards the center of the record, and the potential for distortion increases. Sequence your master accordingly. It is best to put quiet songs or ballads on the inside. Try to avoid sequencing the loudest song as the last track. 

• Try not to exceed the maximum recommended playing lengths per side, as longer playing times will lead to a dramatic decrease in recording level and dynamics.  On the other hand, the requirements of extremely high recording levels decrease the possible playing time.
• Try to avoid 7" vinyl formats at 33 1/3 rpm as the possibilities of the recording and reproduction are most limited at this format. If there is no other solution you have to take into account that the final product will be in some way compromised. Low groove speed limits the recording level and causes a higher decrease of the high frequencies into the middle of the record and can also cause higher distortion levels. Due to these limitations we cannot guarantee eq and level. We recommend using 45rpm up to 5:00/side, and in some cases even longer sides (5:30) can be cut at 45 with better results.
