Introduction

This page is for discussion concerning the details of the QBSH: Query-by-Singing/Humming task. The final outcomes of our discussions will be posted to the QBSH:_Query-by-Singing/Humming page.

Hi Stephen, all

in my opinion, a qbh/qbs system is a system that somehow indexes a melody data base, and then takes singing/humming, i.e. monophonic wav input to search in this database.

A closely related problem is the query by playing, where, if the input is performed on a midi capable instrument, the input to the query system is a midi file.

So now we have two (or if we also allow pv, which we should as we have them, don't we, as input, three) sensible tasks that may be compared. They are namely: 1.) Searching a melody by wav input 2.) Searching a melody by midi input 3.) Searching a melody by pv input.

Now the question of the database/indexing. We have never used anything else than monophonic midis, so I just now realised other folks would maybe like to index from other sources...

For my part, I'm mostly interested in 1.), but would also take part in 2.)

Maybe we should just compile quickly what everybody is expecting of this contest, so may be just fill that form:

--------------------------------------------------------------
|      I will take part in query by  | midi for indexing is  |
--------------------------------------------------------------
| name            | wav | midi | pv  |   ok  |  not ok       |
--------------------------------------------------------------

--------------------------------------------------------------
|                 |     |      |     |       |               |
--------------------------------------------------------------
|                 |     |      |     |       |               |
--------------------------------------------------------------

So, I hope this was not plain stupid and may help clarify issues...

Cheers, Christian
