Treble changes brightness using a high-shelf filter. It raises or lowers a broad region above a transition frequency, affecting cymbals, vocal detail and hiss. A negative gain softens the recording; a positive gain brightens it.
Treble gain ranges from −18 to +24 dB. The default −18 dB is a strong cut, not a boost. Use 0 dB for a neutral comparison or raise above zero to add brightness.
Frequency sets the shelf transition between 1 kHz and 10 kHz. At the default 1 kHz, the change reaches upper mids as well as highs. At 6–10 kHz it focuses more on sparkle and hiss.
Try −6 dB at 6 kHz to soften an edgy mix, or +3 dB at 6 kHz for a little extra detail. The default −18 dB at 1 kHz deliberately produces a much darker result.
Boosting can make hiss and harsh vocal consonants more obvious. Cutting too low can dull intelligibility. Overall peak protection can lower output after a strong boost, so compare tonal balance rather than assuming higher gain means higher total loudness.
No. A treble cut also reduces wanted high-frequency detail. It does not distinguish noise from instruments or voice.
