Recently I made a jQuery plugin named jRecorder to record voice in html pages.

This plugin is very easy to integrate with your web page and you DON’T need a flash server or RED5 server to do the recording

What all you need is a Web Server (PHP or any server scripting language).

You can find the documentation and Download the plugin HERE.

eg: $.jRecorder( settings );

Another advantage is your can decide your recorder design, buttons , mic activity level , recording progress etc in HTML+CSS and this plugin gives you many recording callback events to manage. It is like jPlayer plugin for audio playback.

$.jRecorder ({
'rec_width': '300',
'rec_height': '200',
'rec_top': '0px',
'rec_left': '0px',
'recorderlayout_id' : 'flashrecarea',
'recorder_id' : 'audiorecorder',
'recorder_name': 'audiorecorder',
'wmode' : 'transparent',
'bgcolor': '#ff0000',
'swf_path': 'jRecorder.swf',
'host': 'acceptfile.php?filename=hello.wav',
'callback_started_recording' : function(){},
'callback_finished_recording' : function(){},
'callback_stopped_recording': function(){},
'callback_error_recording' : function(){},
'callback_activityTime': function(time){},
'callback_activityLevel' : function(level){}

This plugin sends recorded WAV file to your webserver, where you can save this file where ever you wish. You can use FFMPEG tool to convert this WAV to MP3 or any other format for further use

The technology used here is, the plugin uses hidden swf file to record the voice and save the binary data in browser’s cache and when the recording finishes, it sends the data to webserver. Thats why you don’t need any Flash media server to capture the recording on time.

The plugin is good for recording voice less than 180 seconds (3 min), else the time to upload the final data to server takes longer.

Feel free to add comments here if the plugin causes any problem or error.

Those who wish to continue the development, the GIT version is available at:

    How can I get an upload to the server confirmation back? I need to know when the upload is 100% complete! Thanks!

  2. Daren says:

    How can I adjust the sampling rate? It is recording in 44,100Hz. I would like to change that. Would that have to be done inside the flash file?

  3. Sara says:

    Hi Everybody,

    Will be waiting for your response.
    Thanks again.

  11. Makara says:


    Thanks for your plugin. I’ve been using it in my project. Everything is fine, except for one thing. It’s when the user clicks on “Deny” button. The flash object is hidden, but its div container is not. It blocks all things underneath it. It would be great if the plugin also hides the div container as well.

  12. Sergio says:

    Hey everyone -

    I was wondering if anyone can help me figure out how i can pass more than one variable to the acceptfile.php. I tried adding the following to the “host” option “?filename=test&id=1″ but only the filename was passed. Can we add more variables in there?


  13. Richard says:

    This works great in Firefox but doesn’t do anything in Internet Explorer for me. Could it be a setting for IE that I am missing, a security thing or such?

    Hello Mr Me

    This example is not working

    I’m using Ubuntu 11, firefox 17.0 and flash player 10, I’m just wondering if it has something to do with my applications.


  32. Conflicker says:

    The swf file is included in fact it is showing in the browser, but jStartRecording function is not recognized. I wonder if it has something to do with browser compatibility.

    Can the recorded voice be saved as binary stream to a database?

  35. Eliot Lee says:

    Does not seem to work in WordPress environment. I am using WP 3.4.2 and have included the jRecorder.js file and also copied all the codes from the example file. The buttons do not work. I keep getting the following error:

    TypeError: getFlashMovie(jRecorderSettings.recorder_name).jStartRecording is not a function jRecorder.js Line 166

    I do have the following settings embedded in my script within the body.

    ‘swf_path’: ‘/wp-content/themes/ppre/js/jRecorder.swf’


    Using jQuery to replace the $. Still not working.

    Anyone had success using this plugin within WordPress (admin dashboard area as part of a plugin).

  36. vivekanand sharma says:

    is there any sucess function in ‘host’: —- to check whether the file is saved successfully on the server?

  37. olivier says:

    It is possible to get and store data locally (and then play back content) instead of sending them to a server?

  38. Chris says:

    Is anyone else having a problem passing more than one URL variable?

    Whenever I set the “host” parameter to have more than one URL variable (“”), only the first URL variable is passed. When I look at it in the Chrome browser’s developer tools under the Network section, the “Request URL” shows as “”

    Yes, I’m using Coldfusion, but that really shouldn’t matter… it’s just a different way to save the posted content.

    Any suggestions?!

  39. Saxo says:

    To see the time format mm:ss

  40. Don says:

    I’m using IE, and I created this page with Serif.

  41. Don says:

    I want to install jrecorder on my site, and let the user to email me their audio file. I’m not that sophisticated with this, but I have tried to embed your source code into my website and I’m not able to get your recorder to work. Is this the right code and do I have all of it?

    $.jRecorder ({
    ‘rec_width’: ’300′,
    ‘rec_height’: ’200′,
    ‘rec_top’: ’0px’,
    ‘rec_left’: ’0px’,

    ‘callback_error_recording’ : function(){},
    ‘callback_activityTime’: function(time){},
    ‘callback_activityLevel’ : function(level){}

    I paste the code into the body and I can see it just sitting there on the page after I refresh it not doing anyting. I would appreciate any help. Thanks.

  42. Dinh says:

    great code! thanks!

    For any problem in IE, go to end of line 52 and delete “,” to fix it.
    For the swf work, upload it to a host or localhost, because the address of .swf file must like “http://…/../”

    i hope in next version, it can convert file to mp3 then upload to server, it will save times to upload.

  43. umang says:

    I’m using ColdFusion, not PHP. Do you have a CF snippet to write the file, or how can I set the recorded data value to a form field?

    First of all – THANK you very much.
    Currently this module save the recorded voice to the same file-name (overwrite).
    Is there a way to send to the module the filename ?
    something like that:
    So we will have the ability to dynamically decide what is the filename [maybe per user-request]?

    thanks for good plugin. But how to adding button pause recording and resume recording?

  63. Mark says:

    Found the solution to my issue. For anyone using Prototype and jQuery: The standard jQuery.noConflict() will not work — none of the callbacks work. To make this work with Prototype, simply insert all your code in the jQuery document.ready() function and it works fine. Anything outside of that, even when calling jQuery instead of $, won’t work.

    I can’t get any of the callback functions to work in FireFox or Safari. Module correctly records and stops and playsback. But none of the callbacks are ever called. I copied the example page exactly. Any ideas or suggestions?

    Thanks! This is awesome.

    If you are going to update this someday, maybe look at the callback for ‘finished saving’ and get it documented / working. Other than that, this is wonderful!

  67. Robbie says:

    Hi, got eveything to work fine. Nice job, quick question…
    Is there any way that this can support multiple recording files. i.e. when Someone recors something it is saved as “hello.wav”, if another recording is made can it be saved as “hello2.wav” or something similar? Because if I am not wrong everytime a recording is made the original wav file gets overwritten by the new one.

    Thanks in advance!

    • Sergio Samayoa says:

      Your server code should handle that.
      For example, I handle the POST with a Servlet. That servlet generates a random file name in which audio is stored then such file name is added to user’s session data so application can grab the audio file and do whatever is needed (store in database blob field for example).


  68. Nikunj says:

    Hello Sir,

    I have added your plugin my script. But in IE i am getting Object does not support property of method jStartRecording. I had given a proper path for jRecorder.swf. Then also error is coming. And this error is coming in IE only.

    And also When i click on send data, File is not going to save. I had also check the host path. It is coming properly. So can you please help me for the same.
