For this purpose, you can use the fetch method or other libraries (for example, I use axios). How to play the audio fileįirst of all, you need to load it from the server. What should you start with? Let’s start with answering several questions. This is when Web Audio API – set of tools for working with the sound in browser comes to help. Check out how to create a custom audio like this one. However, it would be good to have a bigger control over the sound inside our code. It’s great that browser api gives us such simple elements out of the box. # How to work with sound in the background The simplest way to do this is to use the audio element in the following way. However, we want to use it on our page somehow. If we just make get request in the browser, we will get our file. Now, when you know how to load the files from the server, the next step is to get our file on the client. All you need is to make the request by url api/v1/track. You can load any files by using this approach. In general, there are 3 main steps: reading the file and information about it, turning the audio/mpeg into response, file loading. Server.listen('3001', () => console.log('Server app listening on port 3001!')) attach this stream with response stream Ĭonst filePath = path.resolve(_dirname, './private', './track.wav') Ĭonst stat = fileSystem.statSync(filePath) Ĭonst readStream = fileSystem.createReadStream(filePath) The code of these examples is stored in the repository. You can read the whole code here.Īll examples for this article are stored here. Check out how to load the file from the server with Express.js. For the client, you can use file input element. You can fetch it either from the client or server. How to load the sound from the serverįirst of all, you have to retrieve the file you will work with. I have used Express+React for all the examples, however the main approaches I’ve mentioned are not tied to any particular framework. mp3 is that mp3 is the compressed format. It contains information about the discretization frequency, number of recording channels, author of the album, date of recording, etc. Header is the additional information for our data decoding. Each audio file consists of 2 parts: data and header.ĭata is our sound wave, the data array also known as. For this purpose, the audio file format is used. Now when you know the theory of sound wave, let’s see how it’s stored on a device. For example, if the sample rate is 44400, the length of this array is 44400 elements per 1 second of recording. The length of the array depends on the discretization frequency. In a nutshell, you can imagine a sound as a large array of sound vibrations (both in bites and numerical values -NN after decoding). The higher the discritization frequency is – the higher frequencies may the sound signal contain. The number of samples per second is determined by the frequency of discritization (sample rate), measured in hertzs. As the sound is a point in a certain moment, these moments can be selected and saved in samples (numerical values of the waveform data points at certain moments of time)Įach sample is a set of the bits (with 0 or 1 value). The next thing is: how do our devices reproduce this wave? For this purpose, a digital audio – a method for storing a sound in the form of the digital signal is used. If we represent the sound graphically, it will look like a waveform f (t), where t is the time interval. In physics, a sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as gas, liquid or solid. 8 How to rewind the audio to a certain pointįirst of all, let’s get to the basics and talk about what sound is.7 How to display the process of playback.3 How to load the sound from the server.
