Condition A: Full overlap
The bass remains at full level while the kick arrives. Focus on how easily you can locate each kick hit.

Why Does a Kick Disappear Behind the Bass? A Listening Test
Hear the same kick with full bass overlap and with a short level opening around the kick onset. Learn why timing separation can restore clarity without more kick level.
Why does a kick disappear behind the bass?
The kick becomes difficult to follow when the bass is loud during the same onset and occupies the same low frequency region. A short, smooth level opening around the kick can restore separation without making the kick louder.
Keep the volume fixed. Change one variable.
Play Condition A, then Condition B. The files are matched to the same full file RMS. Only the stated variable changes.
Condition B: Short opening
The bass level falls smoothly around the kick onset, then recovers. The kick itself is unchanged.
One controlled variable
Only the bass level around each kick onset changes. The kick source, pattern, bass pitch, file duration and full file RMS are controlled.
What the comparison demonstrates
The short opening makes the kick easier to locate because its onset is no longer covered by the bass. The improvement comes from separation, not extra kick level.
Listen for
- Whether every kick arrival is easy to locate at a quiet playback level.
- Whether the body of the kick remains identifiable after the initial hit.
- Whether the bass returns smoothly rather than leaving an obvious hole.
Why it works
- Kick and bass are relationship sounds. Either one can work alone while the combination fails.
- Time separation can reveal the kick without requiring a large EQ cut.
- A useful opening is only as deep and as long as the groove requires.
Common mistakes
- Turning up both sounds and increasing the total low frequency level.
- Cutting a large permanent EQ hole before testing timing and duration.
- Ducking for so long that the bass recovery becomes the main audible effect.
Repeat the decision in KX1000
Build a readable kick before processing the bass. Use Transient and Body for identity, then keep Sub and Length controlled. Perform the bass ducking or timing change in the DAW.
Original sources, disclosed processing
The comparison uses one KX1000 source kick and an original harmonic bass test tone. Condition B applies a smooth 220 ms recovery window at each kick onset. Both files are matched to the same full file RMS.
- Source material
- Original KX1000 Transient, Body and Sub audio supplied by Dystant Sounds. Any reference tones were generated specifically for this experiment.
- Third party samples
- None.
- Master format
- Mono PCM WAV, 16 bit, 44.1 kHz. This preserves the native format of the KX1000 source files.
- Artifact checks
- Peak safety, DC offset, file boundaries and paired RMS matching passed before publication.
