IOWA music samples - processing required?
Hi,
Just wondering is anybody on the list familiar with the IOWA music
samples? And if you are, do you know how it is best to process the
samples for the purpose of classification?
This is what I'm trying to do - I'm currently developing a musical
instrument ID system. After an extended literature review for my
research, the IOWA samples have proved a popular DB for musical
instrument ID research.However, I haven't come across any literature
which details how the IOWA samples have been processed. For example the
file "AltoFlute.ff.C4B4.aiff" contains Alto Flute note samples played in
sequence across the frequency note range C4 to B4. Unlike the RWC
database there is no mute (silence) gap inserted between the notes in
the IOWA samples.
I'm wondering how do I continue? In order to train and test classifiers,
I'm assuming it is best to separate each note from the IOWA sample and
then train using the individual notes. Is this correct? But how does one
separate the notes? Is there an efficient process, manual or automated.
As the onsets, decays (and other dynamics) are of importance, how does
one decide where to make the cut?
Maybe I'm over complicating this issue, but if there is somebody out
there who has preprocessed the IOWA samples and has thought this task
through, then maybe they can assist?
Thank you,
Joey.
