A modeling system for piano tones is presented. It fully automates the modeling process includes the following three mains stages: sound analysis, sound synthesis and sound quality assessment. High quality piano sounds are analysed in time and frequency domain. Analysis results are then used to design filter models matching the string resonance and create excitation signals using an inverse filtering technique for the excitation-filter synthesis model. The impact of each sound model parameter onto the perceived sound quality has been assessed using Perceptual Evaluation of Audio Quality (PEAQ) algorithm. This is helping to optimise the DSP resources requirements for real-time implementation onto multimedia PC and FPGA-based hardware.
