Redmine Ideas for Projects: Make a HQ audio from many low quality recordingshttps://code.soundsoftware.ac.uk/boards/4/topics/2012012-07-08T14:09:05ZMatthias Mauch
<p>Many people record concerts of their favourite artists on their mobiles or video cameras.<br />Can we make a great sounding combination from them?</p> Ideas for Projects: "Stay, my love" effecthttps://code.soundsoftware.ac.uk/boards/4/topics/2002012-07-07T13:03:08ZMatthias Mauch
<p>Check out the singing the effect used here: <a class="external" href="http://www.youtube.com/watch?v=xb4M6PoI5zs&hd=1&t=112">http://www.youtube.com/watch?v=xb4M6PoI5zs&hd=1&t=112</a><br />It's an old rather obscure Queen song from a time before digital effects made spectral processing easy... Would be great to find out how they did it, and replicate the effect using music signal processing. -- I think it must be an adaptive effect.</p> Ideas for Projects: Singing Sirihttps://code.soundsoftware.ac.uk/boards/4/topics/1992012-07-07T12:59:28ZMatthias Mauch
<p>Control you mobile phone via singing. -- I think we have most of the technology for this at Queen Mary, so it would be a great arty kinda project to trigger calls to your mom by singing "Mamma Mia" -- for example. Sounds too crazy? Nah.</p> Ideas for Projects: some funky Mechanical-Turk-Based projecthttps://code.soundsoftware.ac.uk/boards/4/topics/1982012-07-03T23:07:57ZMatthias Mauch
<p><a href="https://www.mturk.com/mturk/welcome" class="external">Mechanical Turk</a> is Amazons digital labour marketplace. This is ideal for work that needs humans to do be done right, but which essentially any human can do in front of their computers. Best if the work can be broken down, so that many people can contribute in parallel to get it done fast.</p>
<p>The "cool" thing offering money to these people for their work is that it's usually quite cheap.</p>
<p>I would love to learn how to use Mechanical Turk - it has immense potential for validation of Music Informatics algorithms and lots more, so if you're enthusiastic about that and don't know what to do with it yet, let's talk. I'm happy to "invest" a few tens or hundreds of quid in MTurk work — if we can answer exciting research questions with it.</p> Ideas for Projects: make Yanno (YouTube chord extractor) a joy to usehttps://code.soundsoftware.ac.uk/boards/4/topics/1972012-07-03T23:00:11ZMatthias Mauch
<p>Dan Stowell's excellent work <a href="http://yanno.eecs.qmul.ac.uk/" class="external">Yanno</a> is being used by a few people, but not very many, because Dan just made it a prototype implementation.</p>
<p>It would be very easy to change a few things to make it more accessible:</p>
<ul>
<li>Browse songs
<ul>
<li>by title (at least video title, or, if you want to be clever and extract artist and song title, then that's cool, too!)</li>
<li>chord sequence similarity</li>
<li>popularity</li>
</ul>
</li>
<li>allow users to make corrections a la <a href="http://songle.jp" class="external">Songle</a></li>
</ul>
<p>-- the cool thing is that it's a running system and any little improvement will immediately show! So this project is quite scalable to the time and expertise of whoever works on it.</p> Ideas for Projects: Statistical version of Foote's "checkerboard" novelty and structure detectorhttps://code.soundsoftware.ac.uk/boards/4/topics/1962012-07-03T22:50:15ZMatthias Mauch
<p>Foote's novelty detector is a clever little piece of engineering. A high novelty detection function indicates a significant change.</p>
<p>It's so clever because it actually doesn't just measure differences between to adjacent stretches of audio (as my Structural Change feature in its simplest form), but it also takes into account the homogeneity of the parts to the left and the right.</p>
<p>However, as far as I know, it does so using a simple DSP convolutive approach.</p>
<p>A person with a good understanding of statistics could revisit the checkerboard function, and</p>
<ul>
<li>try to understand the statistical patterns behind it</li>
<li>develop a new version based on mathematical statistics that measures how "significantly" two adjacent parts of audio (or other timeseries differ from each other.</li>
</ul>
<p>If more time and enthusiasm remains:</p>
<ul>
<li>Vamp implementation (Vamp plugins run in Sonic Visualiser, which is awesome, and they run fast)</li>
<li>interpretation of the significant difference between two adjacent parts as complexity -- "does that make sense?" would be a question to answer.</li>
</ul> Ideas for Projects: Singing ontologyhttps://code.soundsoftware.ac.uk/boards/4/topics/1952012-07-03T19:02:24ZMatthias Mauch
<p>Klaus Frieler and I have been working a bit on singing intonation, and it's super interesting.</p>
<p>Even solo singing is massively expressive, singers can use pitch (detune, slur, vibrato, ...), intensity (tremolo, crescendo/decrescendo, ...), and timbre (husky vs. clear vs. breathy) to make a melody their own.</p>
<p>I'm currently working on a system that lets musicologists annotate these things more easily than has been possible, but I'm using very simple data structures.</p>
<p>Wouldn't it be great to have an ontology to describe that? If you're into ontologies, I'm certain that you'd say yes! So give me a shout if you'd like to collaborate!</p> Ideas for Projects: Web app to sonify "ndrum" patternshttps://code.soundsoftware.ac.uk/boards/4/topics/1942012-07-03T17:41:22ZMatthias Mauch
<p>There is a little <a href="http://www.eecs.qmul.ac.uk/~matthiasm/ndrum/" class="external">web page accompanying my ISMIR publication on drum patterns</a></p>
<p>It's already got quite a bit of data, and I assume that drummers and other interested folks will enjoy browsing <a href="http://www.eecs.qmul.ac.uk/~matthiasm/ndrum/patternstats/full/patternvisual_reduced" class="external">this kind of ranking</a> <br />but it would be fantastic to be able to play the drum patterns in the pages.</p>
<p>This shouldn't be too hard, because Google have already written <a href="http://chromium.googlecode.com/svn/trunk/samples/audio/drum-machine.html" class="external">a very similar JavaScript script</a></p>
<p>I would love for the ndrum website to remain very basic, non-fancy, and then the drum pattern visualisation/sonification could come as a great little surprise.</p>
<p>This would be great as a ISMIR late-breaking demo.</p>
