DJ Compilation Remastering

Complete your DJ mix by having it remastered to meet professional standards. By having a commercially competitive DJ mix compilation there is no better way to secure pro performances. A few benefits of remastering include increased punch, clarity, and loudness over the entire mix while preserving proper dynamics to insure a pleasurable listening experience without fatigue. Any inconsistent levels during mixes and between tracks are corrected to insure optimal playback. Live DJ mix recordings especially benefit from the remastering process. When creating compressed audio files (mp3, etc.) for online distribution and promotion a remastered DJ mix set will stand out far above the rest.

Two packages are available for remastering your DJ compilation:

The first option is all digital processing and includes manual micro/macrodynamic correction, consistent levels across mix, digital EQ/compression (only if necessary; see philosophy below), and digital limiting.

The second option combines the digital processing package with high quality outboard analog EQ and compression through a pro A/D/A converter to achieve maximum fidelity.

Do you have an old mix on tape that you would like to preserve digitally? Do you have a live mix that suffered degradation during recording? Both of these situations can be addressed during the remastering process with no added cost. In most cases even a highly damaged recording can be brought back to life and preserved.

Philosophy
The goal of the remastering process is to represent the original tracks faithfully while fully preparing the compilation for the digital medium (CD/mp3/ogg, etc.). The best way to accomplish this task is manual micro/macrodynamic correction. Microdynamic correction refers to correcting a change in balance after a cut or a twist of an EQ knob that went too far among other issues. Macrodynamic correction refers to levels of an entire track or tracks in relation to the entire compilation. This process is time consuming and often takes over 4 hours for each compilation and is definitely artistic as if done correctly the listener will not realize any alterations are taking place at all. This process does not alter the EQ balance of the recording. I rarely utilize digital EQ or compression. These tools are reserved for major problems. Problems that can almost always be solved by recording the compilation a second time (unless it is a live set).

In regard to the analog processing package I first go through the whole compilation to correct micro/macrodynamics manually. I then pass the recording through an outboard analog signal chain starting with the Manley Massive Passive EQ essentially at a neutral EQ setting just to capture the character of the EQ and tube output stage. This creates a phase coherent image between tracks on the compilation; instead of sounding like a mix direct from turntables to source it creates an "air/depth" to the recording while minimally altering the EQ balance. Following the Massive Passive is the Cranesong STC-8 compressor. A subtle amount of compression is utilized at this stage to achieve the final dynamics of the compilation (constant average RMS located between -12db to -14db depending on the material).

All processing is conducted from/to 32bit float/96khz resolution files. Even if you recorded your set via a stock SoundBlaster audio interface after digital/analog processing you will recognize an enhanced image/warmth to the recording. I am using the LynxTwo A/D/A which is a pro converter with great specs.

    On receipt of the DJ mix compilation I will review it for any defects that could be solved with another take at recording (when the project permits). If I find any adverse problems I will inform the sender about possible solutions. Poor recordings certainly can be fixed, but following the recording tips below will insure I receive a well recorded mix that can be taken to a truly professional level.

    Questions:
    Q: How long does it take to remaster a DJ compilation?
    A: On average, it takes about four hours to digitally remaster a 74 minute DJ compilation. This depends on the amount of manual micro/macrodynamic correction necesary and can take much longer.

    Q: What formats do you accept for remastering?
    A: 16-bit DAT at 44.1khz or 48khz sampling rate; Red Book CD audio; CDR of wave (.wav) or AIFF at 16-bit, 24-bit, 32-bit float; cassette tape

    Recording tips (gain staging!):

  • If using a DJ mixer that has a limiter or attentuation control (ex. Pioneer DJM 500) set it as high as possible and avoid recording higher than 0db or "in the red" from the DJ mixer. If you slam or overload the limiter/attentuation control on the DJ mixer your recording will lose dynamics (punch & clarity). Note: When using DJ mixers that have a limiter/attenuation control it is ok to slightly go over 0db, but do watch the levels. IE don't sweat it if you have a few brief sections in an hour+ long mix that jump briefly into the red on the DJ mixer.

  • When creating a studio mix compilation try to pre plan levels between mixes and adjust individual channel gains on the DJ mixer as necessary to achieve a reasonably even mix and to avoid excessive attenuation as described above.

  • When recording to DAT or computer try to achieve a reasonable recording level with no clipping. Try to place the peak level at about -3.0 db on a DAT or 16bit on the computer. This will give you a slight amount of room before clipping. If you are recording on a computer at 24bits there is no need to record as loud as possible. A -5db to -10db peak is just fine and will result in a much better compilation after remastering than one recorded near full resolution (especially one with clips)! All too often I will receive mixes that are at full resolution and are clipped; definitely take the time to avoid this.

  • If you are recording a live mix set to DAT consider having your peak levels between -6db to -10db as you will be recording in less of a controlled environment and it is real easy to crank the levels on the DJ mixer while performing on a large system; especially one you are not familiar with.

  • If using a DAT and DJ mixer with limiter/attenuation control: set the limiter/attenuation control to no attenuation then set levels via the input gain on the DAT.

  • If using a computer with an A/D that has a software mixer control panel (ex. M-Audio Delta 44) try to set levels with the A/D software mixer at unity gain (0db); IE don't set it to boost the input signal. Set the A/D to unity gain then adjust the limiter/attenuation control level on your DJ mixer accordingly. Note: Also record your set at the highest bit depth/sampling rate that your A/D supports.

  • Remember that while mixing two tracks together the gain will increase as the audio is summed at the DJ mixer. Follow the tip above and set your peak recording level at the DJ mixer and at your final recording source (DAT or computer, etc.) when mixing two tracks together.

  • Make a few test runs and adjust the limiter/attenuation on the DJ mixer and recording level on your DAT or computer. Listen to the results and pick the settings that sound best; not the loudest ones, but the one that sounds the clearest. Loudness does not relate to the quality of the recording. Loudness/volume will be addressed in remastering through a very controlled process!

  • If in doubt about any of the above record a small snippet and send it to me via email. I will be glad to help you acheive a good initial recording that will result in a pro level DJ mix compilation after remastering.

  • Have fun!
