Digital Audio

Digital audio is technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form. Following significant advances in technology, digital rapidly replaced analog audio technology in most areas. Digital audio systems may include compression, storage, processing and transmission components. It is important to distinguish between the audio coding format, the codec performing the encoding and decoding of the raw audio data, and the container file. Common file formats include .wav, .aiff, .au, .m4a, .mp3, .wma, .ra and .raw.

Not everyone is tied to the Microsoft Office suite these days, as more free cloud-based solutions are entering the market. You might be used to creating presentations in PowerPoint, but did you know Google offers Slides - a free presentation platform? Today we’re going to review this simple workaround to add audio to your next Google Slides presentation.

By default, Slides does not include support for audio files, but they can accommodate tracks from online audio services like Spotify or Soundcloud, or even from a YouTube video with this workaround. Let’s get started.


Add Audio with a Link


  1. From inside your Slides presentation select Insert > Text Box (or select the Text Box button on the toolbar) and insert a text box anywhere on the slide. (Be sure to have the copied link from the audio site you prefer).

  2. Paste some text into your text box (this will be visible in your presentation).Slides01.PNG
  3. Select the text box, from the toolbar select Add Link and paste in your audio link. The text box is now an active link.

  4. Move your text box to your desired location on your slide. You can also resize it to ‘hide’ it on the slide here.
  5. To play the audio in your presentation, head into presentation mode by selecting View > Present. While in your presentation, you can now click the link to play the audio track, it will open in a new browser tab, playing until you close it.

Are you looking to clear some space on your phone for the latest iOS 8 update? Did you switch to Spotify so you no longer need to keep music native on your phone? Run out of space for taking photos while in the middle of vacation? Sometimes the quickest, easiest thing you can do is remove those old songs on your phone that don’t stand up over the years – it’s ok, we all have them.

Let’s review how to delete a song, an album, or all the music from your iPhone.

Disable iTunes Match
Before we start removing music from the iPhone, we have to make sure iTunes Match is disabled. If it isn’t, our phone won’t let us delete music directly from our iPhone (we would have to do so through iTunes on our computer – thanks Apple).

Settings > Music > “Show All Music” slider should be set to “Off”. This will hide all music that is not downloaded on your device, this will NOT affect music that you loaded onto your iPhone from your computer.

If you want a fresh start to your music collection, you can do it all at once, rather than taking the time to delete one album or song at a time.

Under your Settings > General > Usage (this can take a second, as it’s scanning all of your apps) > Music
Music02.pngFrom here you will see information about all of your apps. Select Music > Edit > All Music (red minus sign) > Delete

Great write up! Since a delete option wasn't readily available in the UI, I wasn't even aware this could be done.

I have been fiddling with (oops, I mean evaluating) media players for over a year now.  I purchased a D-Link DSM-520 about a year ago and was pleased with how many file formats It could play, but I found the user interface to be on the clunky side.  It takes a long time to navigate through the menus and the menus are only available after several minutes of power on.

Well I thought maybe I could find a better media player that would have a more responsive user interface, so after much research, reading reviews, scrutinizing media formats of various offerings, I chose an Argosy HV359T as it had an impressive list of media formats that  it could play.  There is a short bootup time, but the menu is readily available and the network files don't take forever to appear.

The Argosy was quite impressive, I got it with a 1TB drive and began to fill it up with videos.  The specs indicated that it could play MPEG-1, MPEG-2, MPEG-4, (AVI, DivX 3.11, 4.x, 5.x, 6.x HD, Xvid, MP4, MOV), DVD Folder, and DVD ISO.  

Sure enough when I played MPEG-1 MPEG-2 files, things went well, AVI and DVD ISO played good also.  When I went to play DVD Folder files, I first experienced a format that was specified, but would not play the audio.  After some fiddling, I found I was able to convert the audio to PCM, but this required re-rendering the entire video, causing some loss of video quality.  I have yet to find an Xvid, DivX or MP4 format that I can play on it.

I am not picking on Argosy, …

I am by no means an expert at anything pertaining to either the music industry nor the technology behind playing your favorite songs and artists' music, however, I have found something that has greatly increased the scope of artists within the scope of musical genres I listen to.

If you are anything like me, you love learning about new artists/bands in the genres of music that you like most.  The problem is that, until relatively recently, there has been no sure fire way to find new artists/bands other than by going to see your favorite "known" (by you) artists/bands play concert venues and learning about similar artists/bands that are the openings acts.  This can get expensive and time consuming, and I do not know about you, but I do not have the time nor the money to pursue new musical talent this way.  The other old school way to accomplish this is by purchasing cd's of your favorite "known" artists/bands and looking in the liner notes at their thank-yous and shout outs to the bands they've toured with.  The problem this presents is one of clutter... I do not need a bunch of cd's around my house when they'll be entered into my iTunes and then not be touched again until I either change music playing devices or until my iPod/iTunes crashes and I need to re-enter them.  I don't even feel the need to address the supposed 3rd option.... traditional radio.  Besides talk radio, genre & demographic based radio stations rarely play anything they are not paid to play by labels …

First of all what is the DMCA? The DMCA is a set of laws first enacted in 1998. The Act was modified on 2000, and again on 2001, 2004, and 2007. Its goal was to update the Copyright act of 1973 for the digital age.

In a world with MP3 playing capabilities in everything, portable media devices that play all types of movies and Digital Rights Management (DRM) technologies there was a gap in the law. Copyright holders were unable to hold their copyrights to the same standards and thus unable to receive compensation for their work.

Why should you care? Just more fat cats getting fatter right? Well this misconception is part of the problem. The money that is paid for a DVD or a CD doesn't just go to the DVD producer, the actors, or the recording artists. This money goes to the stagehands, the microphone operators, the mixing board handlers, the sound technicians, even the janitors. So in effect, every DVD that is ripped and stolen is killing the livelihood of hundreds of people.

Again why should you care? Experts Exchange is based in California. This means that though a majority of its operations happen in the no-man's-land of the internet, means it is still bound by California, and United States law.
The DMCA is a part of US law, and regardless of your like or dislike of the law, the MPAA, RIAA, or the money hungry artists, actors, etc, by accepting membership on this website you are agreeing to abide by those laws.

If your question is questionable, you will be asked…

My understanding of the DMCA, and correct me if I am wrong, applies specifically to circumventing copy protection measures.  

That being said, copying digital media that is Copyrighted but not copy protected, is STILL a copyright violation but it is not a violation of the DMCA.  Only works that are copy protected can be covered under the DMCA.
