Ariel Red Hunter Clive Harrop's 1938 500cc machine recorded at the Southern Loop, Phillip Island, Jan 24, 2004 (64kB in size). A big bore single cylinder bike that kept winning the pre-war category races, beating home Gary Lawton's 1941 1200cc Harley.
1969 MV Agusta 350cc 6 cylinder, pictured left. Recorded on Jan 26, 2003 at the Southern Loop (75kB in size).
1974 MV Agusta 350cc Ago's 4 cylinder recorded Feb 1999.(83 kB)
MV Agusta 500cc? recorded Feb 1999, (88kB).
These MV Agustas were once raced by Agostini in the late 60's and early 70's were recorded at the Southern Loop during some demo laps at Phillip Island in Feb, 1999 and Jan 2003.
1957 Gilera 500 113kb, MP3 mono, 18 seconds playing time, recorded January 2000 at Phillip Island. You can hear Umberto Massetti feathering the throttle to ease the bike through the windy southern loop.
Shelby GT350 recorded at Winton Historics Group S, May 2007. 320Kb. I need to get this one at Phillip Island, full throttle at the start of the main straight.

The sound files are playable with MP3 players like Windows Media Player, and RealPlayer (with a plug-in). Playing time for each is around 15 seconds, best bass response will be heard with headphones.

How the sound files are made
2007, I have just bought a cheap mp3 player with voice recorder to try and get sound samples from in the pit area. I tested the voice recorder at the 2008 Island Classic. It records files as 4 bit .wav which can be converted to mp3 in the computer. I found that pointing the built in mic at the bikes is too loud and results in overload. Next time I will point it up or put a foam baffle in the way. I have also bought a Mac and have found that garage band is a good way to record and edit your sound sample then export to iTunes and then convert to mp3 before uploading to the web.
Recently I have been recording video on a JVC GR-D53AA, then hooking up the audio to the audio-in socket on the computer. I have used Musicmatch Jukebox v 8.1 to create a .wav file, then converted it to an mp3 file for internet publishing. The advantage of using a video camera is that the image is recorded and provides a means of identifying the vehicle later on. Using just an audio recording device made this difficult without taking lots of notes. A disadvantage is controling wind noise. I am going to build a foam cover for the front of the camera to protect the microphone 'holes.'
Prior to 2005, the sounds are first recorded on a portable Sony WM-GX550 stereo tape recorder with a microphone on a lead. The microphone is wrapped in poly-urethane foam to minimise wind noise (motor racing circuits are notoriously windy places.) I record the early laps for practice then record the later laps where the cars/bikes have spread out more. This allows me to isolate a particular sound better.
To digitise the sound recording I connect the tape or Hi-Fi headphone socket to the computer sound card line-in socket with stereo cable. Originally I used Windows Sound Recorder (WSR) to record the tape sound as pulse code modulation (PCM) 8 bit stereo. Then change the file format/properties to M-PEG layer 3 (MP3). I had to experiment with various sampling rates. Other MP3 software on the www will allow higher sampling rates than WSR, but I've found using WSR is okay.
The problem with Windows sound recorder was that you could only record very short segments 10 or so seconds, which means lots of rewinding tapes, and repeat recordings to get the sound levels right. I have since tried shareware such as Wave Corrector and Groove Mechanic to transfer longer segments (up to 2 minutes is sufficient) to hard disk as PCM 16 bit 44 kHz (CD format). These programs allow you to set the physical volume controls while monitoring recording level meters, before you start sampling. I then edit that down to the small 10 second segment required and use WSR to change it to MP3 compressed format. This way the samples are usually less than 100kB in size.
