Sound examples of percussion detection
These are examples of applying a probabilistic model-based method
for detection and labeling of percussion instrument sounds. Examples
include samples from two Turkish percussion instruments, the Darbuka
and the Bendir. Isolated strokes of both instruments were recorded in
anechoic and normal
room conditions with two different strokes, düm (middle shot) and
tek (rim shot). The recorded isolated sounds were used to train the
model. Then, the algorithm was applied for detection and labeling of
simple rhythmic patterns.
These examples have been constructed so that there is the original
recording
for reference and then a MIDI synthesis version of the same pattern, for
which the onset times
and instrument types were extracted from the detection data. These
examples can be used as auditory evaluation of algorithm performance with
different instruments in different conditions.
While comparing the original recording and the resynthesis version it
should be noted that imperfect playing affects class labeling and that the
original temporal structure is well preserved.
