Perceived warmth has two independent routes and boost near 3 kHz projects a voice
Evidence
It is curious to note that a sound can be made warmer by either increasing the energy between approximately 200 and 600 Hz or reducing the energy in the 3 to 7 kHz region. Increasing projection approximately in the 2.5 to 4 kHz region relates primarily to voice production and specifically to providing a hint of a singer’s formant (see Section 4.5.2), which has the effect of bringing a singer out toward the front of a mix. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1518
Categorization
- DEFINE: Clarifies ‘warmer’ and ‘projection’ as distinct spectral manipulations, with projection tied to the singer’s formant.
- XREF: connects to: A sound’s perceived warmth depends on specific frequency balance; Warmth in a sound can be produced by two opposite spectral manipulations; Writing and speaking to one imagined person yields conversational warmth — Freeman Tilden, Interpreting Our Heritage, 382 (+17 more)
