Mon, 15 Sep 2008 Last week, Jeff was out of the office on vacation. Since he'd previously pranked Ion, a few of us plotted to even the score. Stretch suggested that we take the MP3-filled 300Gb external hard drive on his desk and replace all the files with some godawful music. We settled on a slight modification of this plan: for each MP3, I took the first 5 seconds of the real song and pasted it onto the front of one of a selection of songs, including
As luck would have it, the first song Jeff chose to play had been stapled to "Never Gonna Give You Up"—a dead giveaway to him that something was very wrong. During testing, our favorite combination was "What A Wonderful World" cutting into "Heut' Ist Mein Tag". I learned a few things from this. First, most MP3 players will barf if you give them an MP3 whose samplerate (not the bitrate, the samplerate of the decoded PCM stream) changes halfway through. This includes some versions of mpg123, iTunes, Windows Media Player, and WinAmp; mpg321 seems to work fine. Second, the quelcom package is very nice, comprising commandline utilities to cut and paste together MP3s without reencoding (and WAV files, too); if qmp3cut doesn't like an MP3 file, cutmp3 probably will. Third, id3cp (from id3lib) is very useful when you want to replace every mp3 on someone's hard drive without raising too many suspicions. Finally, in retrospect putting 10-20 seconds of the original MP3 rather than 5 would probably have been a little more effective on the confusion front.
