kandi X-RAY | Audio-Visualizer Summary

Audio-Visualizer is a C library typically used in Video, Video Utils, Pytorch applications. Audio-Visualizer has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

For the given input audio file (.wav) the program will give the real time audio spectrum by performing Fast Fourier Transform (FFT) on the audio samples and plot the graph using OpenGL. This Project is implemented in C++ using OpenGL. Three frameworks Aquila-dsp, Kiss-Fft, and SFML are used to perform audio sampling, fast fourier transform and audio playback respectively. The development and testing of this project is done on Linux (ubuntu) using 4.2.0-16-generic Kernel. Interface for the program is given with the help of keyboard.

This is an issue that should be raised with the library author(s), as it doesn't support multiple visualizers attached to the same audio session.

But you can hack in that functionality by extending BarVisualizer and using that new class everywhere as a replacement:

Android - Realtime recording visualization through Bluetooth microphone

Asked 2021-Mar-03 at 08:18

I am using an HFP connection to a Bluetooth Device to get the audio. I am using AudioRecord class for recording with PCM 16-bit encoding at 44100 sampling rate. MONO ch. I am also using a simple library to show the visualization

My target is to show some kind of visualization of the current audio which is being recorded. However, I am not able to find a way to get the Amplitude / FFT of the current audio buffer.

My recording /file save thread looks like this

How To Edit After Effects Template with Python or Javascript?

Asked 2020-Oct-10 at 11:56

I planning to build an online music visualizer but I cannot figure out how to generate high graphic visualization using this After Effects template - Visualization After Effects Template and similar others. How can I Edit this Template with my own text and audio. I want to make something like this - Website Example

I Found Some Visualization Example using Web Audio & p5js But They Were Not as Graphically Pleasing and I want to Streamline The Process By Using Existing AE Templates. I Was Not Able to Find Any Helpful Tutorial or Tool for this, So I am Here Looking for a Solution.

The Process -

User Makes API Request with Link of Audio (web address), Title and Subtitle.
The Video is Processed with the Data in the request and stored in a public access dir.
Link to The File is Sent Back to The User.

The Tech I Am Open to Use : ReactJS, Javascript, Python, Django, Nodejs.

Thanks for your time.

QUESTION

HTML5 Canvas draw lines in a circle and move with music?

Asked 2020-May-20 at 01:46

I am able to draw lines around a circle. I have the basic implementation of the AudioContext API setup.

The problem I am facing is when calling lineTo the line will only grow but not shrink. I am inspired by this https://www.kkhaydarov.com/audio-visualizer/. I am translating this code over into https://codesandbox.io/s/hungry-tereshkova-1pf0c?runonclick=1&file=/src/Visualizer.js:713-725 which is a React.js version.

If you run that code you will see the music play, then the bars will grow once, and then they stick. They refuse to shrink then grow to the beat.

I am not sure where I am going wrong or what I am missing in that code. It seems pretty similar to the other code in the example.

Here is the full code for the Visualizer component.

You just missed a clearRect in your code...
Without that we see the lines grow only because any following shorter line does not overwrite the previous one, they are still getting drawn just we do not see it.

here is the working code:

https://codesandbox.io/s/dry-cdn-ghu4m?file=/src/Visualizer.js:1247-1276

I hardcoded a ctx.clearRect(0,0, 1000,1000) just to show you that it works, but you should use the canvas dimensions there, everything else looks good.

Only recommendation will be to somehow move:

QUESTION

How to pass music from a streaming service into HTML5 element?

Asked 2020-Jan-08 at 23:04

first post here! I'm kind of a noob in JS but I'm working to improve. So, I'm building this audio visualizer using vanilla JS. I still need to work on the CSS but I'm satisfied with it right now - It can decently visualize FFT data for a preloaded song (taken from Free Music Archive)

I now want to connect a streaming service like Spotify to the visualizer so that the music from the streaming service is visualized. But I'm not exactly sure how to go about doing that. I'm using the Web Audio API to analyze the sound.

I would really appreciate it if someone could provide some direction in going about this, thank you!

Note: Site DOES NOT work on mobile yet, sorry.

I think you'd need to use something like the Spotify Web API.

A quick start guide can be found here:

If you want an example, here is another open source project that seems to have done what you're trying to do:
