Thank you for the input folks.
The soundictionary it's not something easy, or that someone would take the work. It's a idea of a collaborative effort For each term everyone would opine and maybe send few records of what he understands by that term.
Let'ws give a very simple example to start. A honk tonk piano. Everyone who listen to one knows that the unison typical adjust creates that particular sound.
For some complex sounds, difficult to describe in words, each one would opine and maybe record his own sound clip to describe the sound. Not just a record of a note, but if necessary a short performance, like chords, or a very short melody, to try to describe better.
Also sound examples of the intented description, followed by the oposed description would help. Give a piano (or sampled one) in the key range that have the effect you refer about, describe it, and get a piano or software with the opposed sound quality for that range.
If we take pianoteq v1 and v4, we can do many interesting comparisons , to describe the metallic and thin of V1, and compare with the present warmer sound of V4. Also using many of the historic pianos, and even the harpsichord, cause such instrument maybe have a tonal quality that help describe some aspect.
I'm not saying the soundictionary will be perfect, but certainly it will help to reduce the misinterpretation when someone says: "This sounds this or sounds that.
Come on, lets put in practice. Specially you who have many piano samplers, many VSTs, or two or three different real pianos on home.
We can start with only the words each one use to describe piano quality, and select the ones that are more difficult to guess in terms of "what sound that means ?"
