Bass boost adds weight to the low end using a low-shelf filter. A shelf raises a broad region below its transition frequency rather than isolating one narrow note. It changes the balance between bass and the rest of the recording.
Bass gain sets the low-frequency boost from 0 to +30 dB. Zero is neutral. The default +27 dB is a very strong boost, so smaller values can be more natural.
Frequency sets the shelf transition from 40 to 400 Hz. Around 80 Hz emphasizes deep bass; 140 Hz reaches bass body; higher settings also affect low vocal and instrument warmth. It is not a hard cutoff.
Try +6 dB at 100–140 Hz for gentle weight, +12 dB for a pronounced low end, or the default +27 dB for an extreme effect. Listen on headphones or speakers that can reproduce low frequencies.
Boosting cannot recreate bass missing from the source. Strong boosts can mask vocals and exceed available headroom. Sonic reduces overall output when needed to keep peaks bounded, so bass may become stronger relative to the rest while the whole track does not become louder.
Small speakers may not reproduce deep bass well. Try headphones and compare the balance of bass against vocals rather than only overall volume.
