ReverSing – zmagovalni študentski projekt – Dnevi Slovenske Informatike 2016

Na Dnevih Slovenske Informatike sva z Luko Zakrajškom predstavljala študentski projekt ReverSing, ki je spletna rešitev za transkripcijo glasbe.

Z veseljem sporočava, da bo ReverSing v naslednjih tednih prešel v javno beta fazo. Za tiste, ki vas rešitev zanima, sledi daljši opis projekta, ki je v obliki letaka na voljo tudi tukaj: ReverSing opis projekta.

 

Problem
Glasbeniki, učitelji glasbe in glasbeni navdušenci se dnevno srečujejo s problemom pomanjkanja notnih zapisov, ki jih potrebujejo za izvajanje skladb. Zaradi splošne dostopnosti storitev kot sta YouTube in SoundCloud je za večino skladb na voljo javno dostopen zvočni posnetek.

Zvočni posnetek lahko s pomočjo transkripcije pretvorimo v simbolno (notno) obliko, vendar proces pretvorbe zahteva tako ekspertno znanje kot veliko časa.

Motivacija
Z združitvijo računalniške znanosti in ljubezni do glasbe smo izdelali spletno rešitev ReverSing. ReverSing je ekspertni sistem za hitrejšo transkripcijo glasbe, v katerem zaradi pomanjkanja primerljivih transkripcijskih orodij na trgu vidimo tudi podjetniški izziv. Rešitev ReverSing ponuja pomoč pri transkripciji glasbe tako posameznikom in organizacijam s področja glasbe, kulture, etnomuzikologije, tehnologije ali obdelave zbirk masovnih podatkov.

Rešitev – ReverSing.si
Spletna rešitev ReverSing rešuje tako ekspertni problem transkripcije glasbe kot tudi podjetniški izziv pomanjkanja primerljivih transkripcijskih orodij na trgu. Na podlagi večletnih raziskav smo razvili metodo transkripcije, ki učinkovito in v realnem času pretvarja zvočne posnetke v simbolni (notni) zapis. Metodo smo prilagodili in jo uporabili kot jedro spletne rešitve za transkripcijo, namenjene glasbenikom, učiteljem glasbe in posameznikom, ki trenutno transkripcijo izdelujejo ročno. Z rešitvijo ocenjujemo, da se čas, porabljen za transkripcijo, občutno zmanjša. Zaradi narave glasbenikovega dela, ki transkripcije izdeluje ročno ali ob pomoči trenutnih manj učinkovitih rešitev, predstavljena spletna rešitev ReverSing, v obliki oblačne storitve, predstavlja edinstveno podjetniško priložnost.
IT izziv
Spletna rešitev predstavlja novost na področju aplikacij za transkripcijo glasbe, saj za razliko od obstoječih rešitev za delovanje ne potrebuje namenske strojne ali programske opreme in je zaradi delovanja v brskalniku dostopna na vseh platformah (računalniki, tablice, telefoni). Uporabljene tehnologije nam omogočajo horizontalno skalabilnost in umeščenost rešitve v oblak.

ISMIR 2015 – Malaga – Day 0 & 1

Another year, another ISMIR. This time, we have submitted 3 posters – two for the Mirex evaluation – Urša and I adjusted the Compositional Hierarchical Model (CHM) to find re-occurring patterns in symbolic data (MIDI), Matija submitted a classifier for Music/speech discrimination; and a Late Breaking Demo poster for WebCHM – a web-based version of the CHM which is becoming the ultimate tool for transcription and evaluation.

As always, I will post few pics and tricks about the conference.

After we landed, we went around the town to familiarize ourselves with all the local places.

We stopped for a research meeting. The food here is interesting, the beer … not so much.

On the other hand, we found the troll :)

During the first day, we visited the technical department of the local university. It was raining and since the roads have no drain shafts, there was a significant amount of water on the road. Trick question: which registration plate is in the following picture?

The university building is HUGE, here is a picture of one of the stairway, easily accommodating  hundreds of students.

MusicTechFest – Friction Drum

On Saturday Karmen and Miha presented the electric version of the Friction Drum instrument (a folk instrument well known in Slovenija, as well as other parts of the world) at Music Tech Fest in Ljubljana. The presentation was awesome, as well as the demo of them playing. I managed to make a few pics with my mobile phone (thus, the quality) and a short video (see below).
