Having trouble understanding Int32Array , Int8Array etc;
const channels = [ new Float32Array(441), new Float32Array(441), ]; for (let i = 0, j = 0, n = 1; i < int16.length; i++) { const int = int16[i]; // If the high bit is on, then it is a negative number, and actually counts backwards. const float = int >= 0x8000 ? -(0x10000 - int) / 0x8000 : int / 0x7fff; // Deinterleave channels[(n = ++n % 2)][!n ? j++ : j - 1] = float; } // https://github.com/zhuker/lamejs/commit/e18447fefc4b581e33a89bd6a51a4fbf1b3e1660 const left = channels.shift(); const right = channels.shift(); let leftChannel, rightChannel; if (this.mimeType.includes('mp3')) { const sampleBlockSize = 441; leftChannel = new Int32Array(left.length); rightChannel = new Int32Array(right.length); for (let i = 0; i < left.length; i++) { leftChannel[i] = left[i] < 0 ? left[i] * 32768 : left[i] * 32767; rightChannel[i] = right[i] < 0 ? right[i] * 32768 : right[i] * 32767; } }

Is it possible to load multiple files and export them as one mp3 file (ToneJS)
Hi, yes, and you don't even need to bring the whole Tone.js lib for that but if you are using it anyway then Tone.Offline is the right thing for this, you get the audiobuffer as output which can be converted to .wav blob. As for .mp3 https://github.com/zhuker/lamejs or any other Lame implementation is worth looking at.
What are some alternatives?
When comparing be-readable and lamejs you can also consider the following projects:
vue-audio-visual - VueJS audio visualization components
Vue.js - This is the repo for Vue 2. For Vue 3, go to https://github.com/vuejs/core
banned - Banned from a site or organization? Account suspended? Censored? Why?
