Re: [Interest] QML Audio loops

I'm guessing, but the audio hardware is shutting down? As a cheap hack, since it is "white noise", (it's not technically white noise) can you overlap two with a time offset so the audio hardware never shuts down?

Hello,

 

I have the following QML that plays an audio file in an infinite loop.

 

import QtQuick 2.11

import QtQuick.Window 2.11



import QtMultimedia 5.8



 



Window {



    visible: true



    width: 640



    height: 480



    title: qsTr("Hello World")



 



    Audio {



        id: noiseId



        loops: Audio.Infinite



        source: "qrc:/448213__florianreichelt__white-noise.wav"



        onStatusChanged: console.log("status = " + status)



        onError: console.log("error = " + error + " " + errorString)



        onPlaybackStateChanged: console.log("playbackstate = " + playbackState)



    }



 



    Component.onCompleted: noiseId.play()



}
 

I used the noise file from here

Unfortunately, after every loop, I hear a clear short hiccup.

Any advice on how to avoid these hiccups?

 

I'm using Qt5.11.2 on Ubuntu 16.04

 

Thanks in advance,

 

Marc
