Hello i want to create a script that allows the user to use the device mic and record audio, then display it using Typescript (.ts) file.
Here is what i have so far.
home.ts
import { Component, ViewChild } from "@angular/core";
import { NavController, App, AlertController, Platform } from "ionic-angular";
import { Common } from "../../providers/common";
import { Media, MediaObject } from '@ionic-native/media';
import { File } from '@ionic-native/file';
@Component({ selector: "page-home", templateUrl: "home.html" })
export class HomePage {
recording: boolean = false;
filePath: string;
fileName: string;
audio: MediaObject;
audioList: any[] = [];
getAudioList() {
if (localStorage.getItem("audiolist")) {
this.audioList = JSON.parse(localStorage.getItem("audiolist"));
console.log(this.audioList);
}
}
ionViewWillEnter() {
this.getAudioList();
}
constructor(
public common: Common,
private alertCtrl: AlertController,
private camera: Camera,
public navCtrl: NavController,
public app: App,
private media: Media,
private file: File,
public platform: Platform
) {
}
startRecord() {
if (this.platform.is('ios')) {
this.fileName = 'record'+new Date().getDate()+new Date().getMonth()+new Date().getFullYear()+new Date().getHours()+new Date().getMinutes()+new Date().getSeconds()+'.3gp';
this.filePath = this.file.documentsDirectory.replace(/file:\/\//g, '') + this.fileName;
this.audio = this.media.create(this.filePath);
} else if (this.platform.is('android')) {
this.fileName = 'record'+new Date().getDate()+new Date().getMonth()+new Date().getFullYear()+new Date().getHours()+new Date().getMinutes()+new Date().getSeconds()+'.3gp';
this.filePath = this.file.externalDataDirectory.replace(/file:\/\//g, '') + this.fileName;
this.audio = this.media.create(this.filePath);
}
this.audio.startRecord();
this.recording = true;
}
stopRecord() {
this.audio.stopRecord();
let data = { filename: this.fileName };
this.audioList.push(data);
localStorage.setItem("audiolist", JSON.stringify(this.audioList));
this.recording = false;
this.getAudioList();
}
playAudio(file,idx) {
if (this.platform.is('ios')) {
this.filePath = this.file.documentsDirectory.replace(/file:\/\//g, '') + file;
this.audio = this.media.create(this.filePath);
} else if (this.platform.is('android')) {
this.filePath = this.file.externalDataDirectory.replace(/file:\/\//g, '') + file;
this.audio = this.media.create(this.filePath);
}
this.audio.play();
this.audio.setVolume(0.8);
}
