 Good morning everyone, I am Prashant Kumar and I will be giving a presentation on sound assessment tool set piano so First I would like to show you the demo. I created a course on each e3 store edX. I have given some assignments so you can take test here and This will open the website here. You can listen to the music which teacher Recorded and I have given to the student now you can choose a file Who is choosing the file so student will choose now when you upload you will get a graph of like The first graph is for teacher like when he played the specific notes and the second one is for the student when the student played those the notes and if he missed something then it will be of different color like that and At the end we have Note missed then notes extra and score so like now you have got score four so it will be Score I have used Smith waterman algorithm and that's evaluate the score Using some attributes which I've used for sound processing and in edX you can see Like now when I refresh it so you have you have got four out of ten. So this will be stored on edX I will continue now Work done by me is the sound processing for musical information retrieval then I did some extraction of different attributes of music such as onset detection and Which time of occurrence effective duration loudness etc Then the matching of two files was done Based on the attributes which were extracted and then the thorough testing was done So some challenges which I faced first of all finding and setting up the open source libraries for my hour was difficult and noise reduction which comes in preprocessing For proper extraction of the attributes was done itself was challenging Then converting mp3 to midi for visualization of musical notes into musical sheet the midi is a file format which helps you generate digital sounds and it can be used to Generate make a musical sheet out of the musical notes. So and I have created test files more than 100 test files So some limitations are testing for large audio file has not been done I have I have tested some files, but thorough testing had have not been done So I cannot say that 90% it will work But yeah, it works extraction of attributes from audio file conducting multiple instrument now I have done testing for a single instrument So in future future scopes are like representation of musical note into musical sheet as I told that we can use midi To manipulate those things and make musical sheet and then taking the course to advanced level the course Which I have in edX is a very basic level course But it can be extended to advanced level after thorough testing of larger files and more notes and more keys Temples etc. So thank you and panigraha will continue
