QUESTION
I have created an application that sings along in the app with the web audio API of JavaScript. This worked perfectly on iOS safari and Chrome, but the sound quality was poor on Android Chrome. To solve this, I tried changing the audio deviceId, but it still didn't work. Does someone have information that might help?
Doubt: After recording, I pass the file to the server and play it on another page. I am wondering if this is causing the problem.
This is my code
...ANSWER
Answered 2021-May-25 at 19:58When trying to build high-quality audio with getDisplayMedia, in the past I've passed in MediaStreamConstraints that remove some of the default processing on the input track:
stream = await navigator.mediaDevices.getDisplayMedia({ video: true, audio: { channels: 2, autoGainControl: false, echoCancellation: false, noiseSuppression: false }});
I'm still learning WebRTC myself, so I'm not sure if these same properties can be passed when using getUserMedia and MediaConstraints, but I thought I'd share in case helpful. It sounds like this might also be about available devices. Good luck!

QUESTION
Is there some formula like frames per second X resolution to determine the bitsPerSecond? I can't understand what values I'm supposed to be using. I want to specify the bitsPerSecond for 720p, 1080p and 4k video. I'm not sure if file type matters but this will most likely befor webm or mp4. I'm afraid some of my files are unnecessarily large while others I'm not using enough bits causing video glitches.
I did find values listed here.... https://restream.io/blog/what-is-a-good-upload-speed-for-streaming/ But even that im not sure how to convert over.
I am using RecordRTC https://github.com/muaz-khan/RecordRTC which is a wrapper for the MediaRecorder.

QUESTION
I am using Electron to create a Windows application that creates a fullscreen transparent overlay window. The purpose of this overlay is to:
- take a screenshot of the entire screen (not the overlay itself which is transparent, but the screen 'underneath'),
- process this image by sending the image as a byte stream to my python server, and
- draw some things on the overlay
I am getting stuck on the first step, which is the screenshot capturing process.
I tried option 1, which is to use capturePage():
ANSWER
Answered 2021-Jan-16 at 15:09desktopCapturer only takes videos. So you need to get a single frame from it. You can use html5 canvas for that. Here is an example:
https://ourcodeworld.com/articles/read/280/creating-screenshots-of-your-app-or-the-screen-in-electron-framework
Or, use some third party screenshot library available on npm. The one I found needs to have ImageMagick installed on linux, but maybe there are more, or you don't need to support linux. You'll need to do that in the main electron process in which you can do anything that you can do in node.
QUESTION
I use Firebase Hosting and would like to realize this web app. (I use Windows 10, Windows Subsystems for Linux, Debian 10.3 and Google Chrome browser. )
- push buttons and record audio (index.html + main.js)
- upload the audio file to Cloud Storage (main.js)
- transcribe the audio file using Cloud Speech to text API (index.js: cloud function)
- write the transcription on Cloud Firestore (index.js: cloud function)
- get transcription data from Firestore using
.onSnapshot. put that data in a textarea (main.js)
I passed step 1~4, but have a difficult in step 5. When I access the web app, it shows transcription data before I record audio.
This data was made the last time I accessed the web app.
When I go through step1 to step5, I get another textarea which is what I want. Could you tell me how can I avoid the first textarea? Thank you in advance.
This is browser's console.
This is main.js(client side)
...ANSWER
Answered 2020-May-27 at 13:03This is because, as explained in the doc, when you set a listener, there is always an initial call.
In your case, this initial call returns the last document that was created in your collection (because your query is defined with orderBy("timestamp", "desc").limit(1)).
You could maintain a counter that indicates if it is the initial call or a subsequent one. Something along the following lines:

I make a simple audio recording web app using Firebase Hosting. I would like to record audio on browser and upload it to Cloud Storage. When I deploy and access my app, I can record audio. However the app failed to upload the audio to Cloud Storage.

Answered 2020-May-21 at 11:58I don't know much about the .wav file but you seem to be trying to store an object instead of a blob or a file that Firebase Storage is expecting. Try creating a var blob = recordAudio.getBlob() and replace file in your put() function with blob instead.

Answered 2020-May-21 at 05:59For you to get the permissions correctly, you need to check your Firebase Storage Security Rules. Configuring them correctly, will provide the access and permissions needed for the audios to be upload to the storage. By default, the rules will ask you to be authenticated, so you need to check to confirm. This way, you can either change your application to have authentication (best option) or the rules.
You can change the rules by accessing the Firebase Console and accessing the tab Rules. If you check the rules and they are similar or equal to the one below, it's confirming that you will need to be authenticated to write in the database, which is causing the error you are seeing.

QUESTION
I am using an open source JavaScript library MediaStreamRecorder to record audio and video webRTC calls in Mozilla Firefox and Google Chrome.
The calls are recording successfully but I am facing the following issue.
If I use the time interval of 1 second (1000ms) in multiStreamRecorder.start() then multiStreamRecorder.ondataavailable event doesn't fire. And that's why No error or No log in console.
But, if I use the time interval of 1.5 seconds (1500ms) or greater, it fires the multiStreamRecorder.ondataavailable event and everything works perfectly fine.
(Only in Video Case)
I want to keep the interval to 1 second (1000ms) only.
...ANSWER
Answered 2017-Apr-17 at 16:46I suspect one second is not enough time for the camera stream to warm up. While you can attach a recorder to a stream instantly, it doesn't appear to be ready for play/recording in zero time.
Video elements have .onloadedmetadata to let you wait for data to be ready; recorders do not.
You can make one though (use https fiddle for Chrome):
