 Yeah, let's see if we are live or not Check my sound first Game should be live. It's working. Okay So we have a thing working now But yeah, obviously it needs a lot more work. It's currently playing random musical notes finally we in the game of EG music generation Yeah, this quickly just in case someone wants to join in Yeah, let's see what we got This code seem to work now when you scroll through EG generates this musical notes, which is fine Accept it So it should be dynamically generated. Yeah, we need to modify the code How to modify the code to generate musical notes dynamically from EG data frequency components What we get we already have the mapping bit Oh, it's going places now Different to what we had Yeah, that sounds the cheer. We need to find closest musical note to EG frequency We already have this code Yeah, we do want to segment into smaller parts Yeah, we will do a linear interpolation That's probably It's not actually being used as a It's a GPT-4. Yeah Yeah, probably should start the new code. We just need to fix Should be a simple Turn the microphone off over there All right, so this convert EG It's not currently being used because it's commented out We have a bunch of tools And the note names. I don't know why I need the note names, but okay Let's just go with this Let's I know roughly what to do, but I want to know how to actually do it So get that as a K convert EG It's partially commented out The active part generator at least musical notes presumably based on the EG data and returns them as json The concept of purchasing Tenant more complex EG data processing. Yeah, that's right Well, if I commented out it doesn't work anymore data loading Guess this notes the problem is if the notes if I comment that Will stop working If I need that All EG data should be there Yeah, there's a problem here Converting the data. Yeah, this will show a different channel After a while, but converting EG data This argument requesting business This meant to be default because that's not the right number Quickly Sprinting the data. Okay Good I'm getting this here G loading check the channel And let's go one by one. Ensure that load underscore data function is correctly reading and processing the EG data If the file path or data format isn't correct, it might not load the data as expected Well, that's okay. A lot done is returning convert 20 G Make sure that the logic for converting EG data to frequencies and then to musical notes is correct The issue might be in the scaling or mapping of the EG frequencies to musical notes You are commented out several lines for returning data and convert underscore E Make sure the final return statement is correctly formatted and returning the expected data Currently it seems like you're returning a hard coded response with notes c4 d4 e4 If this is for testing purposes ensure that the actual data processing logic is correctly implemented and used Ensure the front end while the client receiving this data expects the data in the format you're sending The mismatch is expected and received data formats can cause issues Yeah, it must be mismatched So the code that did work This one And so I know this code worked Looks the same Everyone said there it is So we know This one worked Problem is the only difference It's how this code is structured It's all being been converted EG instead of converted EG It's This business is clearly this Yeah, it's the musical notes instead Yes, that's what the seizure Sounds like I think let's double check The code Save this quickly because it does work That's something useful Yeah, we can get rid of some of the commented out. That was just for testing You can print the musical notes And let's check this scale Need to stop playing some sort of button Actually not meant to be playing multiple times We can't really call it music but let's see If we can Improve it the mapping Can do some fancy neural network something for the mapping Instead of was currently linear A linear interpolation Yes, we don't actually need Hey, this is now happening twice Yeah, load data is in a separate function, but this one That is also a problem They have to fix the code couple of Issues one is crawling He's still late Sessions, but He is not working properly late Several times And the slider is moved That the new Being safe again Yeah, depends on throttle Good idea Yeah, we do want to do that One of things The difference Right stop me please play back. I haven't thought about it. What does that mean? Okay Yeah, that's actually what I want You'll need to implement a mechanism to control how often a particular function can be executed This is especially useful for events that provide very frequently like scrolling or moving a slider Debouncing is a technique that will delay the execution of a function until a certain amount of time has passed since the last time it was invoked This is useful for actions that should only happen after the user has stopped doing something like typing in a search field or adjusting a slider Frottling is a technique where regardless of how many times the user fires the event the attached function will only execute At most once every specified amount of time Yeah, thinking the Fixing it in the back end instead Use debouncing when you want the event handler to be executed after the event stops firing for a specified amount of time It's useful for events like window resizing scrolling or keepers is in a text input Use throttling when you want to limit the number of times a function can execute over time It's useful for events like mouse move or updating the position of a slider For your case where you have a slider to fetch and play music the bouncing might be more suitable It will prevent the function from being called too many times in quick succession That will only fetch new data and play music once the user stops moving the slider To ensure that the back end sends only relevant data for the current slider position and doesn't trigger multiple playbacks If you implement several strategies in both your front end, javascript and back end path and flask go Here's a breakdown of what you can do Update only on slider stop modify your event listener to trigger data fetching in music conversion only when the user stops moving the slider This can be achieved by debouncing the event listener for the slider Yeah goodness It will have this dj feel to it when you actually move Move the sliders it will respond to it Cancel previous requests if a new request is made ensure that any ongoing fetch request is cancelled This prevents outdated data from being processed after a new request had been made Right, so i'm not sure if i should be doing it Front end on back end this one makes a lot of sense I can't think previous requests validate request parameters ensure that the parameters received like start count channel a valid and correspond to the current state of the slider If not respond with an appropriate error message or a status code Synchronized front end and back end ensure the front end and back end are synchronized in terms of what data is requested and received The front end should actually reflect the current state of the back end data Should it stop playing or play on top of it? Update only on slider stop modify your event listener to trigger data fetching in music conversion only when the user stops moving the slider This can be achieved by debouncing the event listener for the slider It's kind of tempting data slider thing You try it out So instead of that Let's try it out maybe Give it the bouncy It really worked it it's cleanest stop this for a sec Save the majors as well fill it Stuff things fix a few things Yeah, we don't use the web media anymore the way So if i click on it only once Okay Sorry for that Can reduce the window size To 10 it's not affected by the window size there's a problem The count is always 100 It's always 100 Okay, so get the Let's see if we're It'll fix good The issue you're encountering where the star parameter differs between the getEag data and convertEag to music endpoints seems to stem from the way the front end JavaScript is handling these requests They should be synchronized to use the same start count and channel parameters for both fetching the EEG data and converting it to music Yes, it should be default That's not just getting the value From the document from the front panel Different options Then let's go from the bottom Because i remember looking at this one before On the back end pass and fast ensure the convertEag to music endpoint correctly versus the start count and channel parameters just like the getEag data endpoint okay Made global isn't it? First you can store the current start count and channel parameters in global variables This will allow you to use the same parameters for both fetching EEG data and converting it to music Some will be dead default That's the whole update data function The application See what it says Then Window size Then window size Test this Okay, we're having a problem Channel zero Let's try get again Start is not defined JS JavaScript Deadline 81 Change convertEag to music Yes Okay, that should get rid of that error Yeah, let's make the window size Then Okay, so that's what the seizure sounds like Just a few more wondering At the end here, we should have a no seizure At the end of the second Okay, first of all It's playing the same Let's stop this. It's still playing the same thing over and over again Too many times Now it's changing with the slider. So that's good And let's see again Let's quickly just keep testing this for a sec Just try a different channel Different EEG channel And why is all this errors? They're not the errors they are I don't know what they are What are they? Welcome Just pop this in make sure it's nothing too critical The error message buffer 118 not found typically occurs in web development context often related to audio graphics processing It indicates that the program is trying to access a buffer A place in memory where data is stored temporary with the identifier 118 But this buffer does not exist or is not available This can happen in a variety of scenarios such as with web audio API, WebGL Or all the JavaScript based APAS that utilize buffer objects I mean, there's no problem. It's still working That's a good thing I have a window size So just to just need to make sure it's generating less nodes So even two nodes It's only played one Yeah, there's something funny with this buffer not found business and it's two Channel four added one node And three not found Okay, I think I know why Because we are not defining them in Python code To only have Hypothesis we only have one of those We actually don't have any of those Do we have a node? a No Do we have a F node? No E node This one That's all Okay, if we have Musical nodes as That actually played all of them not found It's really odd in context of audio Synchronized audio graphics and data processing If the error is occurring in the context of audio or graphics processing Ensure that your data processing like EEG data handling and audio graphics rendering are properly synchronized The error could be a result of attempting to process or visualize data that isn't yet available or has already been processed My hand those musical nodes and this Error, I'm not able to open a whole thing The baffled 20 node found here this one The error baffled 20 node found in the context of using soundfontplayer.min JS suggests that the soundfont player is trying to play a node for which it doesn't have the audio sample loaded This can happen for various reasons such as Specific nodes not available the soundfont you're using might not have samples for certain nodes Especially if they're very high or very low like gsharp 0 or AO in your list This is a common issue with free or limited soundfonts Asynchronous loading the soundfont might not have fully loaded all the samples when you try to play them This can happen if play sequence is called before the soundfont is fully loaded Incorrect node names if the node names are not formatted correctly Or if there's a typo the soundfont player won't be able to find the corresponding sample To troubleshoot and fix this issue consider the following steps Ensure that the soundfont you're using has samples for all the nodes you're trying to play You may need to choose a more comprehensive soundfont or a limited range of notes You generate based on the capabilities of the soundfont Make sure that the node names are correctly formatted according to what the soundfont player expects The node names should match the midi standard node names Modify play next node to skip nodes that are not found instead of throwing an error For example Test your application with a range of nodes to identify which ones are causing issues And address your node generation logic accordingly The issue you're facing with buffer not found Errors in your JavaScript code is likely due to the soundfont player not having samples for certain nodes Especially for those outside the standard piano range The nodes causing errors csharp1, g1, dsharp1, vo, a0 are generally within the range of a standard piano Most possible that a specific soundfont you're using does not include samples for these nodes 1. Use a comprehensive soundfont Ensure that the soundfont you're using includes a full range of samples for all the nodes you need Some soundfonts might only include samples for a limited range of nodes 2. Adjust the node generation range Modify the range of nodes you generate from the EEG data to ensure they fall within the range covered by your soundfont For example, you might limit the nodes to a range more likely to be covered, such as c3 to c6 In your Python code, you can adjust the node generation to ensure that the nodes fall within a more standard range For example Modify the playnext node function in your JavaScript to check if the soundfont player has a buffer for read node before trying to play it You've already implemented a check, but you might need to verify that the check is functioning correctly with your specific soundfont player 4. Error handling in JavaScript Enhance your error handling in the JavaScript code to gracefully skip nodes that cannot be played, as you've already started doing 5. Debugging You might want to add more detailed logging both in your Python code and JavaScript code to understand exactly which nodes are being generated and which ones are causing issues This can help in narrowing down the problem By implementing these solutions, you should be able to reduce or eliminate buffer not found errors in your application Your adjustment to generate frequencies for nodes within a specific range c3 to c6 is a good step However, there seems to be a mismatch in the way you're generating node underscore frequencies and node underscore labels You're generating frequencies for a limited range c3 to c6, but your node underscore labels still span from a 0 to c8 This mismatch might cause issues in mapping frequencies to correct node labels To line these, you should adjust the node underscore labels generation to match the range of node underscore frequencies Here's how you can modify the code With this adjustment, both your frequencies and labels will correspond to the range from c3 to c6 Ensuring that when you map frequencies to node names, they accurately represent it within the desired range This should help in reducing the likelihood of encountering the buffer not found errors As now you're only working within a standard piano range that is more likely to be fully covered by most soundfonds Buffer not found error for nodes like b5 and c6, which are within the range you're generating c3 to c6 So that's a different issue than previously thought Since these nodes are standard and should be available in most soundfond libraries, the problem might be elsewhere Soundfond loading issue Ensure that the soundfond library you're using has indeed loaded fully before attempting to play any nodes There can be a timing issue where the nodes are being played before the soundfond is fully loaded Check if the soundfond player library requires any specific format or initialization process that might not have been completed Soundfond compatibility Confirm that the soundfond player you're using is fully compatible with the soundfond file Some soundfond players might have limitations or specific requirements Try using a different soundfond file known to have a complete range of nodes or try a different soundfond player library In some browsers, the web audio API requires user interaction to start audio playback Make sure that your code isn't attempting to play sounds before any user interaction has occurred Check the state of the audio context and ensure it's not in a suspended state when trying to play notes Double-check the format of the node names Ensure they match exactly what the soundfond player expects, including capitalization and notation like csharp4feedvscsharp4 or db4
