• Overview

    Dictaphone.js is a digital dictaphone application for the web in general and FirefoxOS in particular. You can create any number of sound clips of any length (limited by the size of your local disk partition). You can play back sound clips, instantly seek to a given position of the clip and play or record several clips at the same time. It is based on the WebAudio and IndexedDB APIs.

  • Installation

    The application comes in two packaging:

    For FirefoxOS users only: a packaged (.zip) version, which requires installation. You can install it from here directly by clicking the button below, or install it from the Mozilla Marketplace


    For all supported platforms: An hosted (internet) version, which requires no installation and runs directly from the web. This version can be installed later from an application menu for web runtimes which support it. Click the button below to start the application.

    Run from the web

  • Compatibility

    Dictaphone.js works best on FirefoxOS (version 1.2 or greater), but can also run on a regular Firefox (desktop or android version 25 or greater). It works also in Chrom(e)(ium) (version 31 or greater) and has not yet been tested in Safari . It does not work on IE11+ as this browser does not support the WebAudio API yet.

    WARNING: FirefoxOS users, version 1.2 or greater is required

    The following table list the FirefoxOS terminals for which the application has been tested.

    Manufacturer Model FirefoxOS version Compatibility
    Geeksphone Revolution 1.3 ok
    Geeksphone Keon 1.3 no (1)
    Alcatel Onetouch Fire 1.4 ok
    Geeksphone Peak 1.2 ok

    The problem on Keon is tracked by bugzilla 994260

  • Access permissions

    The application requires the audio-capture permission to access the microphone. In most browsers, the browser displays a dialog to ask for permission to use the microphone when the user record their first sound clip in the session (the permission is reused for subsequent recordings in the same session). If you use the application just to play existing sound clips, permission to use the microphone is not needed nor asked. The hosted version will ask for the right to use the application cache. Both version use IndexedDB storage and will ask for permission to grow the database beyond a certain size if required when recording a sound clip.

  • Privacy policy

    All recorded data is stored locally on the device (the clip names, sound samples, creation date, replay dates). No data is uploaded to any server.

  • Support

    For user-oriented support and suggestions, you can send mail to dictaphone@fos-apps.org. Code enhancement, bug reports and pull requests can be made on github.
