Music on the net: Groundbreaking software developed
New York (PTI): You like a certain song and want to hear other tracks like it,
but don't know how to find them? Well, don't fret. Ending the
needle-in-a-haystack
problem of searching for music on the Internet is a new audio software.
A team of international researchers developed the groundbreaking audio software
that could help music lovers jump to the hidden beats the new Mpeg-7
specification
will automatically extract and classify audio signals.
According to the researchers, such metadata, as it is called, can be used to
tag audio files so they can be more accurately picked up by search engines
equipped to handle this kind of information.
"Such software would be useful not only for delivering a new generation of
musical instruments, but also for designing special effects for cinema and TV,
or for the management of databases in specific applications, such as sounds of
animals, engines and boats," lead researcher Vinet said.
Vinet, who is scientific director at the Paris-based Institute for
Music/Acoustic Research and Coordination (IRCAM), was part of the team that
included
researchers from universities in Spain and Israel, along with companies such as
Oracle and Sony. The EU-funded project was called Cuidado.
The packages they developed consisting of a music browser, an online sound
palette and sound authoring software can analyse and index sound according to
the digital patterns displayed by each particular song.
To do this, the researchers developed a number of techniques for capturing
specific qualities from audio files, such as timbre, energy and rhythm. This
system goes far beyond the methods used online by the music industry.
