I've been looking at a lot of different people's takes on iems and comparing them to mine from crinacle to you and animus. I have been seeing tonality thrown around a lot and im curious how you (and others) measure tonality. Is it by a pitch perfect ear, matching keys on a keyboard or just personal preference with possibly no true understanding of how scales work/sound? How do you come to ahh yes this is tonally accurate?
I mainly listen to drums when i listen to music. So for instance, i own an Anole VX and ive read some reviews that say it has an odd tonality. Woudl it be the BA bass becuase i do find it off at times not necessarily in sound but where it should be.
I think the Anole is one of the most natural sounding iems out there and if im only listening to drums it can't just be drum acurate considering how vast a frequency range they cover. Of course the Anole has its faults but on iems such as the Anole and others i sometimes wonder how people come to such conclusions.
Tone has nothing to do with pitch. A guitar playing a C maj chord will still sound like a C maj chord on any transducer, no matter what since the recorded pitch (frequency) does not change.
Tone represents the harmonic ratio of the instrument/recording. For example, 2 acoustic guitars of different makes can play A440 and they would sound different despite playing in the same pitch due to their harmonic ratio having differences.
The acoustic guitar that has more lower mids (more lower level harmonics) will sound warmer, thicker and richer than an acoustic guitar with more upper mid harmonic content (bright, thinner, sharper attack).
Re: tonal accuracy, it simply does not exist even though I use the term a lot. It is impossible to achieve a 1:1 tonal accurate reproduction. The microphones capturing the musician's instruments are already colored in their frequency response with the room affecting the overall sound. Then it goes through again the sound engineer's speaker for mixing. Mixing involves a lot of EQ and the sound engineer/artist will work together to create a specific type of sound the client wants. Not every client looks for a natural sound, bodied sound. Some intentionally want their instrument and voices to be very colored.
The engineer does not also account for that the recording needs to be played in their exact studio and with their specific speakers to sound good. The mark of an excellent recording is when they work with any sort of transducer - from cheap earbuds to car speakers.
Speakers from the 80s, 90s and modern day all sound different as well as their "ideal sound" of the time when played with their respective speakers. Thus tone will continuously change and progress over time as speakers are changed and how clients want their mix/masters to sound like.
Thus when I refer to "tonal accuracy", it's a mix of both how I expect modern speakers to sound while mixed with my tonal preferences (my target curve).
