The following are some motor noise samples that I performed using digital camcorders
that I either own or had in my posession at one time or another. The camcorders are as follows...
- Sony TRV-120 (Digital 8)
- JVC GR-D72U (MiniDV)
- Canon Elura 100 (MiniDV) -- 1st one
- Canon Elura 100 (MiniDV) -- 2nd one
- Canon Elura 100 (MiniDV) -- 3rd one
Specifics about how the samples were generated are as follows...
- Camcorders were tested early in the morning when there were no outside noises.
- The Sony, JVC, and 1st Elura 100 were tested on the same morning. The 2nd and 3rd Elura
100s were tested on different mornings.
- Each camcorder was tested with their battery attached but using their power supply plugged into
the same wall outlet.
- The camcorders were placed in the approximately the same location on a table in a room during
the tests.
- For each camcorder, I started the tape, left the room, waited approximately the same amount of
time (2 mins.), and came back into the room and turned off the tape.
- The camcorders were set to capture video at SP and audio at 16-bit...all were set to Auto mode.
- The sample footage from each camcorder was captured via IEEE 1394 FireWire using Pinnacle Studio
9 Plus product. There were no dropped frames on any of the captured .AVI files.
- MAGIX Audio Cleaning Lab 2005 was used to import the audio from each of the captured .AVI files,
edit them to shorten, and output them to an uncompressed .WAV file.
- Each of the sound samples provided are the 19-20 seconds captured after the 10 second mark.
This is because the first 10 seconds of each captured .AVI file entailed me leaving the room.
