Light Bass Boost
Apply a 4 dB low-shelf bass preset, then fine-tune the frequency and intensity. The light preset starts at 4 dB around 80 Hz. Compare at similar listening levels; additional bass needs output headroom and cannot restore missing low frequencies.

Warm up a lean recording
A 4 dB starting boost provides audible low-end warmth while keeping the intervention modest. Acoustic music and thin stereo captures can benefit when the missing impression lies near the shelf region.
Locate the useful cutoff
Move the frequency between 40 and 160 Hz. Lower choices focus deeper weight; higher choices extend the lift toward lower instrument fundamentals and can make voices sound heavier.
Listen for muddiness
A low shelf raises a broad region rather than one isolated note. If bass guitar and kick become difficult to distinguish, back off the gain instead of compensating with louder playback.
Save an alternate version
Keep this treatment as a separate listening copy. Its uncompressed WAV can be used in an editor, or converted to MP3 afterward if a smaller sharing file is needed.
