Of Martians and MP3s

I'm getting a lot of response from readers now, the content of which is quite good. If you write, be sure to let me know if I can use the content in an article and if you want me to use your name and/or e-mail address.

This month, in addition to Walter Mossberg’s instructions for converting LPs and Cassettes to MP3 files, I decided to cover a different kind of media: science fiction movies and novels. The topics have nothing in common, except that I found both interesting. Hope there is something here for everyone.

The Martians
The opportunity to write about Martians came about because of a rare Sunday afternoon when I was alone with the TV at the very time the Sci Fi Channel broadcast The Martian Chronicles. A Sci Fi fan since fourth grade (when I read Danny Dunn and the Anti-Gravity Paint) who particularly enjoyed The Martian Chronicles in both print and celluloid, I dropped everything and got out a tape.

The movie set me to thinking about January’s PC Alamode when I made my own feeble attempt at speculative fiction. I was amazed that as soon as I dreamed up some technological miracle to put in my story, I read about it in Wall Street Journal.

If you know this business, however, you know what screaming technological needs must be met and you know where most trends are leading. Who doesn’t know that we’re migrating to palm-top computers and wireless communications? Who doesn’t know that workers are moving into “offices with no walls?” Who doesn’t know that “the rage” among private consumers is now home networks? But how do concepts in speculative fiction hold up over the long run?

The Martian Chronicles, written in 1946, was set in the years 1979 through 2007, most of the action taking place in the early third millennium. The movie was faithful to the novel’s quaint scientific concepts, (out of date even in 1981) such as using a Saturn rocket to touch down on the planet surface, using the Martian “canals” to transport colonists to outlying areas and a US manned Martian exploration program even more ambitious than the Apollo project.

Other concepts were more compelling. The Martian communities consisted of pre-fab buildings that looked a lot like packing crates with windows. The residents used lightweight stackable furniture. They ate and drank from the same bland-looking utensils.

A few concepts stood out like a sore thumb. The women did little but keep house for the men. They wore dresses and heels to do housework a la Donna Reed. The men wore leisure suits, even as uniforms. And there was that pesky telephone that rendered one passage laughable instead of gripping.

Visualize this: The third world war has started. The US abandons the colonization effort to divert funds to the war effort and tells all the colonists to evacuate. When everyone leaves Mars in a panic, someone invariably gets left behind. Frantically, one of the stragglers searches for others like him. He enters one neighborhood and hears a phone ringing. Desperate, he tries to locate the house. The phone continues to ring. Finding the house he reaches out to answer. The ringing dies. Although the phone has a view screen, he finds the phone book and dials (manually) every number starting with the A’s.

The phone was something that even the movie makers in 1981 couldn’t anticipate. Back then, we had no star-six-nine callback, no caller ID, no cell phones, pagers or e-mail. In the grand scheme of Big Technology in Science Fiction, the little miracles that get overlooked.

It reminded me of another film, probably a candidate for Worlds Worst Sci Fi movie, but somehow fun to watch: Godzilla vs. Megalon. The protagonists in this flick were tasked with creating an enormous robot capable of defeating Godzilla (who I assume needs no introduction) before he destroys the earth.

One scene took place in the ultra-modern office of Megalon’s creator. The camera panned the sleek desktops and other worldly art until it came to rest on … a typewriter.

A sci-fi novel of more recent vintage offered a small but interesting technological concept that warrants further investigation. Much has been written about the paperless office, so much in fact that we’ve destroyed a lot of trees in the process. The 1993 novel The Turing Option by Harry Harrison (prolific sci fi writer) and Marvin Minsky (the father of modern robotics). The book is a speculation on uses of Artificial Intelligence.

What interested me was an obscure passage regarding a laser printer. After reading a printout, the protagonist puts the stack of papers back into the printer’s paper tray. The printer erases the original printout and produces another printout on the same paper. I hope this concept does for printers what Star Trek’s communicators did for cell phones.

The MP3s
As a preface to Walter Mossberg’s instructions for converting LPs and Cassettes to MP3s, let me say that we did try this with my favorite album. It worked like a charm, and the audio quality was quite good. You’ll probably want to start a new MP3 for each track  rather than putting the entire album on a single MP3. To do this, on your recording software, click the stop button when a song ends, then click the start button when the next song starts.

“Mossberg’s Mailbox”
Wall Street Journal

Q. I've made MP3 files from many of my CDs and I really enjoy listening to them and burning CDs with my favorite mixes. But I also have a lot of music that's on old cassette tapes and even older LP records. How do I get these songs into my PC as MP3 files?
A. Many readers have asked me about this. It takes a little more work, but it's possible, with the right hardware and software. Here's how to do it, with a Windows 98 PC.
First Make sure your PC's sound card has a socket called "line in" or "mic in." Most have one or the other, or both. These jacks allow the computer to take in sound from external sources, including cassette players, audio receivers and microphones.
Next Make sure you have an audio device that plays your cassettes or LPs that also has a stereo output jack, or a pair of them. This could be something as simple as a Walkman-type portable cassette player or as sophisticated as an expensive receiver through which your turntable or cassette deck works.
Third Get a cable that has one end that fits your sound card (usually a 1/8 inch stereo RCA jack) and another end that fits your audio player. This latter end might be a similar small, single stereo jack, a larger single jack or a pair of plugs.
Fourth Obtain a software program that can record music from such line-in or mic-in sources and turn it into MP3 files. This is crucial. Without such software, the process won't work, even if the hardware is correct. One warning: many "ripper" or recorder programs can only create music from CDs that are inserted in your PC's CD-ROM drive. A few others can do so using songs coming in from external devices. I recommend using my favorite MP3 software, MusicMatch Jukebox, which can accept input from either a line-in or "mic-in" socket on the sound card.
Fifth Hook up the cable, turn on the audio player and the PC, and select the cassette or LP that you want to record. In MusicMatch, go to the Recorder menu and set the "Source" from your CD drive to either "Line in" or "Mic in," depending on which sound card port you're using. If you're using another MP3 recording program, you'll have to perform a similar setting.
Sixth Open up the Windows sound mixer. This is the program that should appear when you double-click the little speaker icon at the right end of your task bar. You will use it to control the input volume of your music. It has various sliders or controls for the PC's different audio functions. Using the mixer's options menu if necessary, make sure you see an audio control section called "Line In" or "Mic in," whichever you're using. Make sure it isn't muted, and set it for the volume you'd like.
Finally Go back to MusicMatch, start up the recorder module, and press record. Almost immediately, start playing your cassette or LP. The software should convert the tracks to MP3s. It won't be as foolproof as with a CD, which is already digital, but it should work OK. If it doesn't, your PC's hardware and software may not be optimally configured, or configured at all, for recording sound inputs. Before calling for help, try fiddling with the recording settings in the Windows Multimedia control panel.
