Calling a sound warm does not mean ya feel physically warm no matter how many times ya repeat it.Your own remark demonstrate easily that you have no clue about this phenomenon...
Synesthesia can refer to an association between touch and sound like between letter and color... What trigger this association is not necessarily a perceptive spatial cues in the case of letters and colors, but perhaps a translation of the body sensation from a cognitive pathway in the case of the touch and hearing in the audio phenomena for example... This is certainly a possibility....
Then insulting people AFTER 8 posts, demonstrating by this sentence that you have no understanding at All of what is synaesthesia, what do you think we think you are?
Synesthesia:
« One third piece of evidence that perceptual/sensory factors may subtly influence otherwise conceptually triggered synaesthesiae comes from Eagleman (2010). Eagleman has recently shown that the visual form of letters may have an impact on their colouring.His data suggest that letters that are similar in shape (e.g., E, 3) may be closer in colourthan those that differ in shape (e.g., E, X). In a similar way, Millset al.(2002; also Witthoft & Winawer, 2006) have shown that visual similarities in letters can dictate how colours are transferred across alphabets in bilingual synaesthetes (e.g., the Cyrillic letterIand the Arabic letter N tend to be coloured similarity for English-Russian bilingualsynaesthetes, as do�and R). In other words, synaesthetic systems appear to be built around perceptual features at least to some degree. However, the exact nature of this visual influence remains unclear. It is possible that perceptual/visual influences may play absolutely no role whatsoever in the actual triggering of the synaesthetic experience.»

This definition will help you and make you able to think WITHOUT insulting:
«According to Day (2005), there are two major
categories of synaesthesia:
1. Cognitive synaesthesia: Photisms or other
synaesthetic perceptions are induced by stimuli associated to symbolic meanings, transmitted within specific culture (graphemes, phonemes, people’s names, week days, etc.).
2. Synaesthesia “proper”: Stimuli of one sensory
modality are perceived simultaneously and
involuntarily through an additional sensory
channel (e.g., seeing music)»

And perhaps a last clue to help you from the same areticle i can send to you free of charge:
«It is not an accident that various authors defend that
synaesthesia research can bring new insights into
our understanding of the neurological bases of
metaphor and language (Cytowic, 2002; Marks,
1978; Maurer, Pathman, & Mondloch, 2006;
Ramachandran & Hubbard, 2001b). Subjective
reports reveal striking parallels between the
synaesthesia and cross-modal associations reported
by nonsynaesthetes. For instance, Ward,
Huckstep, and Tsakanikos (2006) demonstrated
that the associations of sounds to colours in
synaesthesia showed the same pattern of correspondence between luminosity and tone pitch as
in cross-modal associations of normal persons.»
Dont apologize.... But stop insulting anybody in your first posts.... Especially if your I.Q. is not what you think it is....
If you are unable to understand these articles because of your attention span limitation, which your insults demonstrate is perhaps a problem with you, i suggested a 4 minutes video which will not induce your anger against audiophiles:
