audios | MP3 Player App | Audio Utils library

I've been making a game using Unity and I added a slow motion function. Afterwards, when I added audio, I wanted to change the pitch of all audio whenever the slow motion function ocurred, but I can't seem to do it. I've been using Brackey's audio tutorial (here if you wanna see it) to guide me into using audio in Unity

Here is my audio manager:

I'm trying to get the length of an audio file. Sadly I run into some issues trying to retrieve that file. This is my code (which is in Kotlin):

I am capturing user screen and audio using getDisplayMedia and getUserMedia and able to record the complete screen capture. But this works only on Chrome and not on Firefox. When I run my application on Firefox it throws error 'DOMException: AudioContext.createMediaStreamSource: No audio tracks in MediaStream'. Below is my code snippet. I have latest version of both browsers installed. Any help would be appreciated. Thanks in advance.

Note:- Its throwing error on line context.createMediaStreamSource(desktopStream)

On pageload I get the errors: Failed prop type: The prop url is marked as required in Sound, but its value is undefined Failed prop type: The prop playStatus is marked as required in Sound, but its value is undefined Basically all the properties of the ref named "sound" are not applied to the soundobject.

I have a video file input.mkv It contains 2 audios and only 1 substring.

I want to convert it in mp4 with same quality. It should contain same: 2 audios and 1 substring.

I tried:

ffmpeg -i input.mkv -map 0:v:0 -map 0:a:0 -map 0:a:1 -map 0:s:0 -c copy output.mp4

I got an error message:

I'm very new to IoC idea and I'm trying to jump over the Service Locator pattern. I chose the Kangaru implementation. Suppose I want to use Audio and Logger services in different places of my app. What I have now:

From the highest level, I'm trying to pass a Blob to a function that will transcribe the data and return the transcript. I'm struggling to get the async parts of the process lined up correctly. Any insight would be appreciated.

The two files I'm working with are below. In the record.jsx file, I'm calling the googleTranscribe function ( that is located in the second file ) to do the transcription work and hopefully return the transcript. This is where I'm running into the problem - I can get the transcript but cannot return it as a value. I know I'm doing something wrong with async / await / promises, I just can't quite figure out what I'm doing wrong.

record.jsx

So i have this nodejs that was originaly used as api to crawl data using puppeteer from a website based on a schedule, now to check if there is a schedule i used a function that link to a model query and check if there are any schedule at the moment. It seems to work and i get the data, but when i was crawling the second article and the next there is always this error UnhandledPromiseRejectionWarning: Error: Request is already handled! and followed by UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). and it seems to take a lot of resource from the cpu and memory. So my question is, is there any blocking in my code or anything that could have done better.

this is my server.js

Here is the code:
