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)."
audiopreview is a simple and easy command-line program for previewing large numbers of music files.
Although the name may suggest otherwise, audiopreview also plays video files.
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.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
