HTML5 audio recording

We are looking for a developer who can develop a HTML5 recorder for modern browsers (Firefox, Edge, Chrome, Safari). The application needs to be in pure HTML 5/ Java Script and without any plugins (no Flash or Java).

The application has the following requirements:

1. Record audio with a microphone in the wav-format

2. The recorder has to display an alert, when there is no microphone connected

3. Solution only in Java Script

4. The user interface of the recorder has these elements:

a. A running timeline, when the application is recording and in playback-mode

b. Buttons for record, stop, rewind and play

c. A slider for audio volume

5. The recorder should load request parameters at start time

a. The maximum time for a record

b. The link of a present record, ready for playback

c. The path for the record to save

d. Some user specific data

Requirements of the technology and the structure of the application

1. Use separate files for HTML, Java Script and CSS

2. For CSS use Bootstrap (Version 3.3.6).

3. For the recorder buttons use the video player icons from Font Awesome (Version 4.5.0)

We already have a Java applet version of the recorder. This Java applet could be the template for the HTML5 version. You will get a screenshot of the recorder with a detailed list of the requirements. Furthermore we will give you a link to a working example.
