QUESTION
This is the goal that I am trying to achieve:
I would like to be able to take the audio recorded from the phones microphone and process the levels at given frequencies into an array that I could use to create a sort of "Bar graph" visualizer. I also need to calculate the BPM of the song playing to know the cadence at which to update the visualizer at.
What I am really looking for is just getting the frequency array and BPM calculations. I can deal with the actual visualization part if I can just figure out how to process the audio.
This is pretty much what I'm looking to make:
From the research I have done, it looks like a possible solution is using FFT (Fast Fourier Transform). For that I found this: stackoverflow. But that stackoverflow thread is for Java, and my app is currently written in Kotlin. I have read that it is possible to import Java into Kotlin, but I haven't been able to make it work in the couple of attempts I made. So maybe some advice on that would help.
Anyways though, I did end up finding a library that was written for Kotlin Nier Vizualizer. It does have a vizualization similar to one I'd like to reproduce, but for the life of me I cannot figure out where I would pull the frequency array from. I tried reading the buffers before they were passed into the visualizer, but it's just an insanely long string that I'm recieving. I mean, I'm not sure what I was expecting, but I could definitely use some help understanding how I would translate that into a data format that I can actually use.
Here's an example of where I'm at: KeyFrameMaker.kt

Answered 2019-Sep-16 at 17:51If you're using the Android Visualizer class, you don't need some other FFT library, because the Visualizer class provides a getFFT() method that returns to you audio that has already had an FFT applied to it. You just have to convert it to magnitudes on a dB scale to get it to look nice in your graphics.
You need to request microphone permission before you try to instantiate Visualizer or it will fail to initialize. Visualizer is largely implemented in C and is mostly a JNI wrapper, and as such throws lots of RuntimeExceptions if things go wrong, so you need to wrap your initialization and setup calls in try/catch blocks.

while running running production build its getting failed and showing Fatal Error: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory and while running development build its getting passed
I tried to run using set NODE_OPTIONS=--max_old_space_size=8172 && npm run build:production , in this case build is getting passed in local but same command is not working in server and getting failed
webpack.config.js
...ANSWER
Answered 2019-Aug-19 at 15:28I Found the fix for above issue in server , memory issue was there so its causing above error, to make it work i added below task just after "npm install" next step -> "npm install increase memory limit" and after that -> have to run this task "increase-memory-limit".
production build getting successful after this changes.
QUESTION
When I try to open my custom visualizer on an expression tree in a .NET Core project (targeting 2.2), I get the following exception:
An unhandled exception of type 'System.TypeLoadException' was thrown by the custom visualizer component in the process being debugged.
Could not load type 'System.Runtime.CompilerServices.IsReadOnlyAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
The following code (derived from the stack trace, at the end of the question) appears to have the same issue:
...ANSWER
Answered 2019-Jul-03 at 16:02As you can see the following message is refering to a NET Framework 4.0 element:
Could not load type 'System.Runtime.CompilerServices.IsReadOnlyAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
The maximum NetFramework target you could use is defined by this element.
QUESTION
I have react 16.3.2, and today i attempted to upgrade it through yarn upgrade react@latest it has upgraded the yarn.lock's react@^16.8.2 but when I console.log out the react version it still outputs 16.3.2 Did I miss something?
Here's my package.json
ANSWER
Answered 2019-Feb-14 at 22:18yarn upgrade does not update package.json, only the lock file. Actually, none of the yarn upgrade flags do. There's a long discussion about this in here
You can do the following:
- Reinstall React with
yarn add react@latest - Install a npm package to check updates, for example, npm-check-updates. Run it to update
package.jsonand then tryyarn install. - Or you can install that specific React version
yarn upgrade react@16.8.2.
This is the intended behaviour, even though it is very confusing in the docs.
QUESTION
I've written a script in python with selenium. The script is supposed to click on some links in a webpage. When I run my script, It does click on the first link and then throws an error stale element reference: element is not attached to the page document instead of chasing for the next link. I searched a lot for the last few hours to find any solution to get rid of this error but no luck.
I'm not interested in their data so any solution other than the perocess of clicking is not what I'm looking for. How can I click on the links until the last link?
This is my attempt so far:

QUESTION
While debugging and stepping through code, I tried to add a method to the watch window which takes a long time to evaluate (probably 20-30 sec as it involves network connectivity). After about 15 seconds however, I get "evaluation timed out" error.
I found the following solution which involves changing the registry value NormalEvalTimeout under HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\Debugger to extend the timeout length:
How to keep Visual Studio debugger visualizers from timing out?
However I don't seem to have that entry in my registry (or any other timeout related entries for that matter). I also looked in the WOW64 regedit. I tried to create the NormalEvalTimeout entry from scratch but that had no effect.
Any ideas where to find the registry entry or if there is another way to do this with VS 2015? Thanks for the help.
Edit: here is the list of registry entries I have (on Windows Server 2012 R2):
...ANSWER
Answered 2017-Mar-02 at 01:57As our previous discussions, we could make sure that it really has no the registry value NormalEvalTimeout under HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\Debugger, and if you want to set the timeout value for other debugging windows, it also has the requirement for the Windows Environment. At least, we make sure that it doesn't have them in the windows server 2012 R2.
