The general user interface is very easy to control. Open a browser to www.filelab.com. Select audio editor, select your file and then begin editing.

This is the user interface within the browser:

Across the top of the interface are 2 main pages the first page is labeled Audio Effects. The 2nd page is labeled as Generate. We will cover the former in that it will be the most used.

Amplify: Decibels are a exponential scale: 0 dB is the lowest a human ear can hear. 10 dB is 10 times as powerful. 10 times more powerful than that is 20 dB. 1000 times as powerful as near silence is 30 dB. As you see minor variations within a decibel range can be significant. FileLabs Audio Editor allows for steps as low as 1dB up to as high as 6 dB.

Fade In/Fade Out: Audio Editor also allows for linear fade in and fade out. This can be very useful for audio tracks that

Normalize: This will take and find the peak of a waveform and bring all of the other audio to a level somewhere in-between the highest peak and the lowest. This is a good tool to use when you wish to bring the sound floor level up. It will amplify the weaker sounds while attenuating the sounds that are too high.

Mute: Mute is pretty self-explanatory it mutes the selected area of the audio file.
Invert: Invert flip the left and right channels within the audio file. You can select an area to invert or it will invert the whole file at once. It will change the polarity of the file on the horizontal axis.

Limiter: This is an audio compression algorithm that takes the peak and locks it into a set decibel range. It is generally used to remove a distortion to the audio signal. It is not evident in use and also on the site which form of limiting is in use, be it either hard clipping or with a fast release.

Auto Correction: Automatically enhances the sound aural characteristics reducing the dynamic range, normalizing and equalizing the audio.

Echo: Repeats the selected sound with the selected effect.

Reverb: Adds echo and multiple reflections of it. Use it in modeling acoustics in a hall, empty apartment,or some other type of room.

Tempo Change: Increases or decreases the tempo. Music will play faster or slower but the pitch is unaffected.

Equalizer: Boosts or cuts specific frequency bands and provides a visual representation of the resulting EQ curve. Use this to boost bass, midrange or treble of an audio file.

The 2nd page of the software application enables you to either generate silence or a signal. The signal can be a bell, chord or 440 Hz, A signal. This can be useful for testing audio devices.

This software is feature rich, fast and surprisingly elegant for a completely free browser based package.

Mozilla Prism is offered as a Firefox extension and standalone application. It can basically turn a website into an application so that the website is untied from the web browser.

There are a few advantages but also disadvantages of using Prism to run websites in their own application window instead of running them in the web browser.

Advantages include increasing the stability of the system as the single application window is no longer affected and affecting the web browser window. The other is unaffected from crashes or other problems.

The application window is also inheriting all the benefits of programs including the ability to run them at system startup or minimizing them in the system tray.

Prism is available for Windows, Macintosh and Linux computer systems. The extension’s add-on page has not been updated as of now and the last version of Prism that is offered there for download is not compatible with Firefox 3.6 yet. It will take less than 24 hours for the page to be updated with the latest version that is compatible with Firefox 3.6

Prism can be downloaded from the Mozilla website or the Prism project page.

Mozilla Prism (via Download Squad) can be downloaded and installed as a portable standalone application or as a Firefox web browser extension. Running the standalone application will open a configuration menu where the user enters the url of the web service that should be run on the computer desktop. Additional settings can be configured including shortcut creation, selection of a icon and the elements that should be displayed in the Prism interface (with our without navigation bar, status messages or navigation keys).

The service will automatically start after the configuration finishes. It can later be launched from the shortcut location that has been defined during configuration.

The interface looks like a minimized version of the Firefox web browser without all toolbars and elements. This is a distraction free way of providing web services on the computer desktop. The main benefit besides being able to launch web applications by clicking on a shortcut is that users can do less harm in comparison to the normal web browser interface where they can change settings or navigate to different pages.

A bookmarklet is available to create Prism applications on the fly. There are also official and user created application bundles available for various web services.

Several options – including proxy support and font selection – are only available if the “show status messages and progress” option is enabled during setup.
