Audio Searching
Audio searching today is also based on the idea of appended text. Typically audio
clips or audio files are appended with a text description, so that the user can
query by the appended description. This enables one to search on the text
description of Mozart’s Symphonies and get back the music file, but does not able
one to search on all music dealing primarily pianos and/or violins.
The searching of audio is an interesting challenge for developers in the sense that
audio could be searched by having the user draw the corresponding sound wave,
but very few users can actually describe what a sound wave would look like.
Another approach might be to have the user hum a few notes of the music to the
computer via a microphone and have the search tool bring back the completed
piece of music based on the notes that were hummed. Regardless of the
approach, these are very interesting challenges for developers in term of
searching audio based on the content of the sound.
