This article presents a real-time software solution that allows musicians to visualise the timbre content of their musical tones. The timbre representation is based on the spectral estimates of the SnailAnalyser, for a high frequency precision, and on a harmonic-like representation. After a brief review on the derivation of these estimates, some second-stage estimates and the mapping used for the timbre representation are described. The visual representations in the application have been prototyped using the MAX software and developed with the Juce framework.
