10 things you must do to finish your track

Get over the line

How do you know when a track is finished? It's a tricky question, and one that we all wrestle with. It's all too easy to spend hours tinkering with a mix and putting off the moment when you hit the mixdown button.

However, at some point, for the sake of both your productivity and sanity, you've got to stop. To help you get over the line, we've put together a 10-point checklist of things that you need to do before you say 'I'm done'. Hopefully, this will help you to stop worrying about the minor details and focus on the things that matter.

1. Clear out the clutter

It’s easy to get used to a mix with layer upon layer of sound, but unnecessarily busy tracks can be unlistenable.

Often, this clutter exists in the low-mid or high frequencies and is caused by multiple instrument layers. Use or adjust high- and low-pass filters on individual tracks to create more space, or revisit your arrangement, removing elements one by one to re-assess their impact on the overall mix. Less is often more!

2. Assess the kick/bass relationship

This vital aspect usually needs a final check. Listen to the balance between the two to assess whether either is too dominant and, if necessary, notch a space in your bass sound for the kick, using an EQ and/or a spectrum analyser to hunt the precise kick frequencies.

Try putting a 100Hz low-pass filter on your master bus to monitor bass levels and spot low-end clashes.

3. Check the sub level

Following on from the previous point, excess sub bass can be problematic on big systems, and it’s easy to unwittingly accrue when mixing on smaller nearfield monitors.

If you’re mastering your own mixes, use all available tools to check this - including headphones, bass heavy systems such as car stereos - and do some spectrum analysis, comparing your mix to similar tracks. The low-pass filter trick in the previous step can help.

4. Check overall vocal levels

If your track has vocals as a focal point, their level has to be right. Take time to get the levels right in specific sections using automation, riding phrases and words if necessary.

As a final test, listen at different levels, on different systems and in mono to make sure the vocals are neither smothered nor too prominent.

If you’re still unsure, opt for the slightly higher vocal balance, or run off an alternative ‘vocals up’ mix.

5. Listen to transitions

These are usually delivered naturally by live players but can require more thought for programmed tracks. If you’re lurching from section to section and lacking an overall ‘flow’, transitions may be badly balanced or just missing. Remedies include sweeps, crashes, stops/silences, impacts, bends and slides.

If a transition still sounds too abrupt, adding a touch of long reverb helps smear transitions without dominating the mix balance.

6. Check it in mono

If the mix balance changes a lot when played in mono, “phasey” stereo sounds/effects (such as) reverbs may be too dominant. Narrow or rebalance them so the mono and stereo mixes are consistent, ensuring a solid mix that’s compatible with mono playback systems.

7. Listen on different systems

Monitoring on multiple alternative listening systems can be confusing, so it’s best done to highlight significant problems rather than as an additional monitoring setup. Car stereos, in-ear headphones and consumer devices such as laptops, tablets and smartphones are all useful, particularly when judging lead instrument balance.

Make notes on anything you think needs attention, then return to the studio and work through each point.

8. Get on top of the pops, clicks and artifacts

Clicks and pops sound like digital errors and have no place in your final mixdown. They can be caused by poor or missing crossfades, level overloads, audio file errors or badly edited audio comps.

Listen for any strangeness, zoning in on problem areas and resolving these issues at source. Often, the best tool for this task is a pair of headphones.

9. Keep your mixing hat off

Be as objective as possible, ‘hearing’ the track as would a first-time listener.

Techniques include coming back to the track after a break (be it minutes, hours, days, weeks... or more!); listening from a different position or outside your room with the door open; A/B-ing with commercial tracks you rate; listening to the track as background music while doing other tasks; and sticking your mix in a shuffled playlist.

10. Push it into a limiter

Output limiters are a key aspect of mastering and can highlight balance issues, particularly excess low and high frequencies. Insert this last on your master output and see how loud you can make your mix before distortion gets too audible. A good, balanced mix will “go loud” quite easily; if yours doesn’t, it likely needs more work.

Study an RMS meter - an RMS peak of -10dB is plenty, though higher is possible by tailoring low frequencies.
