Vibrato Dataset

Vibrato Dataset is the extended version of the previous dataset. It consists of vibrato sounds for five different instruments providing different pitch ranges of notes, melodies, articulations, scales and musical techniques as staccato and legato. It includes 295 note tracks with vibratos and corresponding non vibrato tones and 49 melody and articulation tracks. Data Collection It is organized according to the source of the recordings. Sounds with vibrato and no vibrato are presented within the folders with their annotations in cvs format. All annotations except than the alto saxophone recordings include derivative analysis of pitch parameters. The reason of choosing following subsets is that all subsets are created in MTG and they are open source. The MTG violin recordings includes single notes of two octaves and four different melodies starting from different pitch are recorded in wav format sampled at 44.1 kHz. Each sound separated by semitones is recorded four times for no vibrato,slow, standard and fast rates of vibrato. Melodies were played for no vibrato and vibrato at a standard rate to have the attenuation at the end of the note. Good-sounds alto-sax recordings main feature is that it offers the quality of the vibrato sound and provides vibrato tracks of articulation, scales and staccato, legato techniques. The remaining subset offers a good variety of instruments and mostly two octave range of vibrato-non vibrato pairs. Dataset Description The database is meant for organizing the sounds in a handy way. It is organized according to the creator. In each three datasets, annotations and analysis parameters are available within the csv files and each has 11 field descriptor. Carlos_Vaquero Transverse_flute Violin Violoncello Bassoon Good-sounds-Alto sax Alto-sax MTG - Violin Violin Except than alto-sax recordings, each annotation files contain following parameters: Peak_Percentage: Percent wise proportion of peaks in first derivation of the pitch trajectory. Mean_Difference: Mean value of the differences of two consecutive peaks. Max_Difference: Maximum separation of side by side peaks. Index_Max (first one): Index value of the maximum peak in the derivative array. Location_Max (%): Location of the maximum peak in the array, percent wise. Start_End_Time (seconds): Starting and ending time instants of vibrato in the recording. Duration: Duration of the vibrato part of the recording.
