Peaks.js uses the HTML canvas element to display the waveform at different zoom levels, and has configuration options to allow you to customize the waveform views. Peaks.js allows users to interact with the waveform views, including zooming and scrolling, and creating point or segment markers that denote content to be clipped or for reference, e.g., distinguishing music from speech or identifying different music tracks.

            Turning audio data into waveform data?
            Webpack package.json not running

            QUESTION

            Turning audio data into waveform data?
            Asked 2021-Jan-03 at 21:54

            I don't understand how this https://github.com/bbc/peaks.js/blob/master/demo/TOL_6min_720p_download.json can be turned into a waveform visualization with peaks.

            I see the data in that file is a flat array of numbers. I am trying to understand how to convert those numbers into something meaningful for visual drawing.

            Check out this fiddle to see a deeper look into the code https://codesandbox.io/s/cool-dijkstra-fyw25?file=/src/App.js

            The goal is to create peaks with a high and low that looks like the image. I assume every 2 indexes represent a peak, but I don't want to assume anything.

            I am pulling the JSON and passing it into the draw function like this

            Expanding on my comment on getting the max and min then us those to get a relative value, I'm doing the 15px bounds as you suggested, so the center will be 0 and the upper bound will be 15px, and the lower bound -15px that will be used in our calculations...

            Here is what we can do:

            The log answer your question: -> When using npm: npm install webpack-cli -D -> When using yarn: yarn add webpack-cli -D

            Install it using npm or yarn.

            Apparently one package has separated in two others.
