Musical Instrument Detection

Abstract

Traditionally, musical instruments are categorized into four main categories or families: string, brass,
woodwind, and per- cussion. For example, violin is a classic string instrument, and clarinet belong to the woodwind
category, horn and trumpet are brass tools, and piano is usually classified as a drumming instrument. Sounds produced by
these tools bear different acoustic qualities. A few features can be obtained from their sound envelopes, including attack
(the time from silence to amplitude peak), sustain (the time length in preserving level amplitude), decay (the time the
sound fades from sustain to silence), and issue (the time of the decay from the moment the device stops playing). To
reach accurate classification of instruments, more complex features need to be extracted.
