 Respect to dignitaries and my dear friends. I'm Panik Rai from NID3C and I would like to brief you on my project and sound assessment tool set on Tabla. I'll start my presentation with a demonstration of my course, which is Tabla 1.x, which is an edX. This course basically consists of all the video lectures, which includes all the basics of Tabla. You can see that, which basically includes the postures, the phonetic systems of Tabla, and all the bowls, bio, dyup, all the information about it. It basically aims at training a beginner. Apart from that, we have a set of assignment, which teaches our software as its evaluation. Sir, the UI is entirely the same, but I have a course on Tabla. That's Tabla. Look at the example course. No, ma'am. I made my own course with all the video lectures. Sir, basically, it is a normalist version of this course, which uses the tempo, the matching of the bowls, played by the teacher and the student, and you're not using the same algorithm. Sir, I'm using that algorithm along with that. I'm using one more algorithm. That's KMP Algorithm for string matching. That's a modified version of KMP Algorithm for string matching. In the KMP Algorithm of string matching, we have two strings, which matches, but here it is a string with least of strings. So, we use that and get the score. It is actually a normalist version of the score. I don't agree with your score, man. Oh, it's a big Tabla. Sir, that's why only that's the wrong point. It should play those four only, but it has been playing a lot. That's why it's wrong. So, that's why it's getting lower scores, sir. What is wrong? I'm not able to detect it? No, strings are exactly the bowls played by the teacher and the students. So, we'll get, sir, see, basically, Tabla is a percussion type of instrument as said by sir. So, we don't have an exact function or library, which could say you that this segment of part is this bowl. Sir, this is string at the notes combination. Ma'am, kind of. See, the teacher file is having these strings, which the student need to replicate. But the student played these things, and he's like, he didn't play it exactly. He should play it exactly, but it's not that ideal. We are considering student as not ideal file. So, that file, it is like in between something. Ma'am, in Tabla, you can have all ranges of values because what we are using is basically the value chosen by testing on 200 audio sample test files made by the teachers, the students, and the... Time sample, that is this time... Can you give a mathematical equation which we can understand? Sir... Talking in words is very difficult. You give a mathematical equation for the sound. Sir, the mathematical equation goes like this. You will first get the matching of the string. That's most important. That's 50. The 50% of the score is based on that. No, no, no. I'm not talking about that. Ma'am, how are you making the strings? What are the strings' definitions? Ma'am, strings are basically the detected bowls. The detected keys, which you can say. What are the components? See, in piano, OK, sa will be 241, re will be this frequency. It will be that frequency, correct? And the only time there will be a frequency difference, OK, will be that instrument is untuned, OK? But if you play the keyboard that you are playing, sa will always be 241. You can detect a note perfectly, OK? Tabla is where you hit, OK? So, there is not going to be an exact bowl match. So, you are going to... Am I right? Yes, sir. So, that is where the difference between percussion and non-percussion. Non-percussion, there is some exactness of a note. Is there a change in the frequency at that point? Might be. No, but it is, as he said, it is not digital. It is universal. Sir, the same bowl played in two tablas can be different, even if the tabla is tuned. Can you show the diagram of something? Sir, that is basically the loudness diagram. That is basically the loudness diagram on timestamp. See, I am not able to understand, first of all. That is why I am asking you. You show me. So, show me some variation, that there is a variation somewhere. Sir, basically what thing which we have used? Sir, just use the algorithm which is generated. Sir, the integrated thing which we are using, that is not a one-liner thing. So, that is the basic difference. Sir, we have to get a gist of it. Sir, see this. If you observe the mod send, there are some varieties in it. This is the... Some graph. Sir, this is what? You can plot a graph. You should have plotted, no? Sir, I should have plotted on everything. I mean some. Sir, some part we plotted over there. Who can understand this? Sir, from here only... For your analysis, actually you should have done it. Sir, we use this as our reference. These type of seats as our reference. Oh, this is a standard thing. This is a standard. Available. See, generated by one of the... Test rights. One of the library elements that is using in generating these numbers. Basically, tabla is a percussion type of instrument. So, not any libraries or functions or any research work is there for us to follow up and then find out any direct functions which distinguishingly determines all the balls. So, we have to go through the testing and then I'll go for the challenges. Apart from the unavailability thing, we're even giving the noise reduction thing to the sound file. And we're also allowing the student to upload the music file in any of the format. Maybe WAB, maybe MP3. Doesn't matter. Our software will work on that. Apart from that, ma'am, there are some similarities in the balls which even an expert's ear can say. So, we need extensive testing on that. So, fixing the parameters for that and the values for the parameters was a tough job. That's one of our biggest challenge in that. There are actually a lot of future scopes in this which includes the detection of balls which uses both the hands simultaneously. There are balls which needs both the hands to be played in sync and simultaneously. So, those type of balls detection hasn't been done in this. This is one of the best future scopes. Apart from that, the extraction of tabla sound from file containing multiple instruments. That can be one of the future scopes. Then, there could be a course with intermediate level of tabla teaching. So, these are a few of the future scopes of my sound assessment toolset. That's all from my presentation. Thank you.
