I thought I'd post the code I came up with in case it helps someone else down the road. This creates a .wav file; I then used audacity to rip it to a MP3 cd. 
use Win32::Sound;
use strict;

my $rate = 14100;
my $WAV = new Win32::Sound::WaveOut($rate, 8, 2);
Win32::Sound::Volume('100%');

my $data    = "";
my $counter = 0;

# an hour of beeping -- what fun
for my $c (1 ..2*60) {

    print "$c beep\n";

    # .25 sec  tone
    for my $i (1 .. .25 * $rate) {
        my $v = 128 + 50 * sin($i);
        $data .= pack("cc", $v);
    }

    # 29.75 sec sec silence
    for my $i (1 .. 29.75 * $rate) {
        my $v = 0;
        $data .= pack("cc", $v);
    }

 }

$WAV->Load($data);        # get it
$WAV->Save("beep.wav");  # write to disk
$WAV->Unload();           # drop it
