问题 I have a webpage with an audio tag in it. It works fine in Mobile Safari. However, when I open the link from the Facebook app on iOS, it opens in the in-app browser. Here, the audio refuses to play. It will show that it's playing if the controls are showing but there's no audio. Video seems to work fine but the audio tag does not work. Is there a way to make this work or even to force the link to open in Mobile Safari instead? To try it out, share http://www.w3schools.com/html/tryit.asp

问题 Android Chrome V(50.0.2661.89) has webRTC support. So i'm trying to set up Webrtc call between Mobile chrome browser and Desktop. All works good. But on Android mobile (Samsung S4, all event few more brands). audio output is coming on both Ear piece and External speaker . I could not control the output audio to playback only on Ear piece.

问题 I try to execute a function on an audio play event : jQuery('audio').on('play', function () { /* ... */ }); But my element is not present at the time this function is executed, so it's not selected. Instead I have the habit to use a different syntax when I need to trigger event for dynamic added content : jQuery('.constant-container').on('play', 'audio', function () { /* ... */ }); Where the .constant-container does not change. But this solution does not seems to work, the audio element does

问题 I've been playing around with MediaElement.js for a while now and have a new application that uses 20 players on a single page. I'd like to be able to have the songs stop when another one is played - and not to overlap the tracks when they are playing. I can't seem to find an easy way to hack this - perhaps someone knows of a way? Thanks. 回答1: In jQuery, you could do $('video,audio').each(function() { $(this)[0].pause(); }); Let me know if that works. 回答2: A quick and dirty one ;) $(".mejs

问题 I'm having a bit of trouble rewinding audio in Javascript. I basically have a countdown that beeps each second as it gets towards the end of the countdown. I tried using; var bip = new Audio("http://www.soundjay.com/button/beep-7.wav"); bip.play(); but it didn't beep every second which I'm guessing has something to do withit having to load a new sound every second. I then tried loading the sound externally and triggering it with the following code. bip.pause(); bip.currentTime = 0; console

问题 The server saves the audio data as base64 data string. The mobile web client fetches the data and plays the audio. But found an issue in mobile Chrome in iOS and android that the audio with data uri can't play (issue). To make it work, I was wondering if there is a way in the client side to convert the data string to an audio file (like .m4a) and link the audio src to the file? 回答1: Figured out directly using the web audio api has the best compatibility across the mobile browsers in iOS and

问题 I'm making a site that involves a lot of multi-tracked, audio loops.

My question is, What is exactly the audioBuffer and how is the data coming from getChannelData related to frequencies. and how can I extract frequency data from the audioBuffer... Also, if someone can explain just a bit about sample rates etc. also this would be great. Thanks! 回答1: An AudioBuffer simply

问题 I'm making an audio player with JavaScript, everything works fine until I add a sound visualizer. When I pause the song and then play it again, the sound gets more louder every time I do it, until it gets distorsionated. I'm newbie with the HTML5 Audio API, I've tried to set the volume as a fixed value, but not works. The code of the visualizer it's: function visualizer(audio) { let context = new AudioContext(); const gainNode = context.createGain(); gainNode.gain.value = 1; // setting it to
