Most MP3 players display information in ID3 tags, a data area in MP3 files that can hold information such as artist and album name, song title, genre, and even a picture or URL. Taking the time to fill out the ID3 tags for your music can pay off. Not only does it add another layer of communication with your listeners, it can increase your music's popularity, because an increasing number of search engines and file-sharing applications recognize tags.
Editing ID3 tags used to be a chore, with most players and encoders forcing you in and out of dialogs as you tagged one song at a time. Fortunately, Kevesoft MP3 Tag Clinic (Windows) makes tagging a snap. Its simple interface combines a Explorer-style folder browser with a spreadsheet-like window that displays the tag contents for multiple files simultaneously. You can quickly arrow-key and copy-paste down the columns to tag all your songs in a single pass. The demo version of Tag Clinic is limited to eight entries per folder in its unregistered state, but you can work around that limitation pretty easily. Better, if you like it enough to use it consistently, pony up the $19.95 registration fee.
Mac users running MacOS 9 or above might want to check out Three-2-One Interactive's ID3X ($9 shareware). For more on the ID3 tag format, visit ID3.org.
In the magazine article, I reviewed four of the leading signal-processing plug-ins for Winamp, and explained how they can be used to restore and enhance MP3s. If you like a particular effect and want to apply it permanently to an audio file , or if you're just getting MP3s ready to burn to CD, you'll need to make an uncompressed file. The Nullsoft Disk Writer plug-in does just that, streaming Winamp's audio output into a WAV file. Disk Writer is a standard feature of the Winamp player, but it's buried two levels down in the Preferences dialog, so many people aren't aware of it. Here's how to set it up:
Remember to de-select Disk Writer and return to Direct Sound output when you're finished, so you don't fill your hard drive with WAVs.
Any MP3 can benefit from some signal-processing touchup before it's burned to CD. Although popular CD-burning programs such as Roxio Easy CD Creator and Ahead Nero offer a few enhancement effects, detailed MP3 polishing requires a more powerful audio editor. Depending on the content of the MP3, here are the steps you might take:
You'll likely get the best results with a program that supports professional (e.g., DirectX, VST, MAS, or TDM) versions of each DSP effect mentioned above. However, lacking such tools you can still apply these processes to MP3 files using one of the Winamp multieffect plug-ins mentioned in the magazine article and outputting the result to a WAV file through Winamp's Disk Writer plug-in.
There's a spate of sound improvers for casual listening and gaming, some of them made by the same firms that make Winamp or DirectX plug-ins. To use these devices, you insert them between your computer and speakers, or between your cable box or game console and home stereo. While not appropriate for recording or critical monitoring situations, any of these devices can add a nice quality boost to recreational sound. (All links open a new window.)
The TDS Passive Audiophile is exceedingly simple -- one solitary toggle switch. Essentially a harmonic exciter, it's built using passive analog electronics, so it requires no power supply or battery. Also notable are its gold-plated in/out jacks; rugged metal housing; and subtle, tasteful processing. TDS appears to be retooling its product line and cooking up a software version.
The Binaura SoundPet widens the stereo image and adds a little volume. The device offers three different settings for this effect, but you'll probably want to leave it on the top setting all the time. Winning points for their permanently attached AC cords and novel industrial design, SoundPets look like little robot hamsters or space pigs.
QSound Labs' UltraQ,
like the SoundPet, is a stereo image increaser. The UltraQ offers a little more
control, with separate settings for music and games, mono-to-stereo conversion,
and automatic mono/stereo sensing. UltraQ loses points for weak-feeling switches,
a large desktop footprint, and an external AC adapter. QSound makes some of
the finest professional 3D and spatial processors; this offering is not quite
in that class, but then neither is its price. The company also offers a Winamp
plug-in, although it hasn't been updated since its 1.0 release in 1999.
SRS Labs' Wow Thing is the pick of the litter. It sounds significantly better than its software counterpart, and has knobs to adjust the effects. The device's Wow effect sounds like a combination of stereo widening and exciter, while its TruBass is a tight, warm bass boost. It also features a volume control, bypass switch, and neat translucent housing. This unit delivers the most obvious results of any of the devices mentioned here. It's quite pleasant sounding and by virtue of combining exciter and super-stereo with bass maximizer solves more sound-quality issues than the other boxes. It loses half a star for its cheapo wall-wart adapter, but it's still the top of its class.
