处理记录后，我尝试在下面的代码中记录和预览音频。我想使用 PHP 将预览音频上传到文件夹中。谁能帮助我完成发送 MP3 文件的 AJAX 部分？我参考了很多链接，但我无法找到这部分的解决方案。

.center_div {

border: 1px solid #808080;
position:absolute;
top:50%;

margin-left:-250px;/* half width*/
margin-top:-75px;/* half height*/
padding:25px;
}
.recording_label {
display: block;
text-align: center;
padding: 10px;
font-family: sans-serif;
font-size: 1.1em;
margin-bottom: 25px;
}
.loader_bg {
min-width: 100%;
background: #c5c5c5;
min-height: 20px;
display: block;
}
.loader_bg1 {
min-width: 90%;
background: grey;
min-height: 20px;
display: inline-block;
position: relative;
top: -20px;
}
audio {
}
</style>
</body>
</html>
像这样获取源文件：
<audio controls="" id="audio" src="blob:null/b63e868d-1628-4836-85da-90cf1b5b65c3"></audio>
如何将此 blob 转换为
mp3修改app.js中的代码如下，在ajax调用中设置url
$(function(){
var max = 40;
var count = max + 1;
var counter = setInterval(timer, 1000);
function timer() {
count = count - 1;
if (count <= 0) {
clearInterval(counter);
$(".recording_label").html("Recording...");
$('.loader_bg1').css({'min-width':''+(100)+'%'})
Fr.voice.record(false, function(){});
Fr.voice.stopRecordingAfter(40000, function(){
//alert("Recording stopped after 40 seconds");
Fr.voice.export(function(url){
$("#audio").attr("src", url);
$("#audio")[0].play();
}, "URL");
});
recordingSec(40);
return;
}
$(".recording_label").html("Recording will begin in " + count + " sec.");
var percent = (count / max ) * 100 ;
$('.loader_bg1').css({'min-width':''+(100 - percent)+'%'})
}
});
function uploadAudio(){
Fr.voice.exportMP3(function(blob){
var data = new FormData();
data.append('file', blob);
$.ajax({
url: "server.php",
type: 'POST',
data: data,
contentType: false,
processData: false,
success: function(data) {
// Sent to Server
}
});
}, "blob");
}
function recordingSec(sec){
var count = sec + 1;
var counter = setInterval(timer, 1000);
function timer() {
count = count - 1;
if (count <= 0) {
clearInterval(counter);
$(".recording_label").html("Recording stopped...Playing");
$('.loader_bg1').css({'min-width':''+(100)+'%'})
//stopRecording();
return;
}
$(".recording_label").html("Recording started [ " + (sec - count) + " / " + sec + " ] sec.");
var percent = (count / sec ) * 100 ;
$('.loader_bg1').css({'min-width':''+(100 - percent)+'%'})
}
}
Server.php 示例
<?php
$path = 'audio/';
$location = $path . $_FILES['file']['name'] . ".mp3";
move_uploaded_file($_FILES['file']['tmp_name'], $location);
?>
