New Projects - Fresh from the Labs
I love niche programs, especially in the area of multimedia. If you're like me, you probably have a folder full of MP3s and Oggs collected from the last ten years that's reached the point where you've forgotten half the files in there. This month, I stumbled upon the charming little command-line program, audiopreview. To quote the project's Freshmeat entry:
audiopreview is a command-line tool that plays previews of many audio file types (Ogg, MP3, etc.), video file types (AVI, MPEG, Real, etc.), and Internet streams. It also can be used as a regular command-line media file player (that is, play the files entirely like yauap or mpc123 would).
Packages for audiopreview are available in Debian/Ubuntu format or the usual source. If you're running with the source, according to the man page, you need the following libraries: gstreamer0.10-plugins-base, gstreamer0.10-plugins-good, gstreamer0.10-plugins-bad and gstreamer0.10-plugins-ugly.
I found I also had to install the intltool library to get past the configure script. Once you have the library side of things sorted out, compile the program with the usual:
$ ./configure $ make
If your distro uses sudo:
$ sudo make install
If your distro doesn't:
$ su # make install
Using the actual command can be as simple as entering the folder where the files you want to hear are located and entering:
$ audiopreview *
(The * is used to indicate all the files in a folder.)
Once the program is running, you'll be greeted with a simple track listing, along with other relevant information in purple. As far as controls go, the spacebar pauses and unpauses the stream, N plays the next stream, and P plays the previous stream. R restarts the current stream, and Q stops playing and exits the program.
That's the basic usage out of the way, but let's refine it with some command-line switches to hone your usage. For new Linux users, these are added at the end of the command, like this:
$ audiopreview files-to-play --switch
If you plan on using audiopreview to play a whole song instead of in segments, use the switch --entirely or -e.
If you want audiopreview to start over again after the last song has been played, use --loop or -l.
As mentioned previously, audiopreview also can play some video formats. However, this being a command-line program, there's a good chance you may not have X running. If so, you'll want to disable the video to avoid errors. To do so, enter --no-video.
The default starting position for each file seems to be random, which might become annoying for those looking for more specific sections of a song. Thankfully, you can specify which section of a song you want to hear with a simple numerical switch. Add: --position=POSITION or -p POSITION, and replace POSITION with the numbers 0, 1, 2 or 3. 0 sets the position to the beginning, 1 to the middle, 2 to the end, and 3 makes the start position random.
Last but not least, engage the all-important shuffle function with --shuffle or -S. For example:
$ audiopreview *.mp3 -p 1 --shuffle
The above command plays all the MP3 files in a directory, sets the starting position to the middle of a song and shuffles the order in which they're played.
You can work out the rest from here, but honestly, do yourself a favor and check out the man page with:
$ man audiopreview
Ultimately, audiopreview fills a nice little niche that will appeal to anyone sorting through large collections of music (and some video) files. DJs in particular will find this of real use, but I found it great for rediscovering songs I hadn't listened to in years. Love it.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
