Piano Room Recording (both piano and flute)
Description: Piano recordings were captured in the Hervanta Library's piano room, a quiet, echo-prone space ideal for high-quality audio. Professional pianos provided clear and natural timbre, while the room's acoustic design minimized noise interference and enhanced sound distribution. Recordings were made using a mobile phone audio recorder to balance performance detail with environmental variability, providing realistic training data.

Recording Details: Instruments were played in diverse styles—single-tone for capturing fundamental timbre characteristics like pitch and intensity; multi-tone for harmonic analysis; and ensemble for studying instrument coordination and reverberation. Techniques like legato, staccato, and arpeggio covered a range of dynamics, tonal variations, and rhythmic patterns to enrich the dataset.

Purpose: The dataset supports audio signal processing tasks like timbre analysis, spectrum decomposition, and instrument recognition, providing a versatile foundation for model training and further musical signal processing research.
