In this dir: more WAV samples, recorded with a telephone pickup coil. These are all free of copyright: I release these into the public domain - not that the public would be that interested.

WARNING: some of these sounds are VERY loud - please make sure that your speakers are turned down a bit.

20q_velociraptor.wav: Radica Games Ltd. '20Q' guessing game: I think of something and it tries to guess what it is. I thought of a long-necked dinosaur and at question 20, it guessed 'Velociraptor' - pretty accurate!

audigy2_nx.wav: SoundBlaster Audigy2 NX (USB sound device). The phasing/ chiming sound is the sound of the system clock (48 kHz). I was recording the sound with itself.

b_tube_and_telephones.wav: 'B-Tube' is a Linx B-Tube Bluetooth speaker, capable of A2DP output and regular basic Bluetooth handsfree audio. The sample features me connecting to the B-Tube, calling my landline number and saying something, and then phoning T-Mobile to check my balance. I called the Orange number by mistake, and then called the T-Mobile one. When not outputting sound, the B-Tube made odd little clicks when I pressed buttons on the mobile phone. I have 3 pounds 74 sterling and I am on the T-Mobile 'Everyone' plan.

DAB_Radio.wav: Pure Sonus 1-XT DAB radio, playing several different stations.

dvd_drive.wav: noise emitted by an LG DVD drive as it plays a video DVD ('Walking Dead: The Complete First Series').

eee_pc.wav: Asus Eee-PC 701. Firefox was loaded, and I started the Javascript PC Emulator ( The buzzing sounds were emitted as the Linux kernel scrolled messages up the screen. When the ramdisk decompressed, there was a loud 'sawing' sound. I closed Firefox and started Skype, where I called my mobile phone and recorded the audio from the Eee PC's speaker.

f91w.wav: the obligatory Casio F-91W sample - dig those retro beeping sounds.

futurist_a220.wav: the not-quite-so-retro sounds of a Casio Futurist watch, with the loud sound at the start being the vibration motor/buzzer. I never use this as it drains the battery, and annoys me - the regular beeper wakes me up quite well.

grandstand_astro_wars.wav: Grandstand Astro Wars game. This is an 80s game that I bought on eBay, after missing the one that I had, all that time ago. I was quite annoyed that I was not able to pick up clear audio from the speaker, although you can hear it faintly.

h3760.wav: Compaq iPAQ H3760, running Familiar Linux. The screeching sound was emitted while Linux loaded. When it finished, there was a quiet buzz from the LCD. The pulsing sounds are me entering my password at the login screen. There's more buzzing as I load some utilities (clock and terminal, I think it was).

hx4700_1.wav: Another iPAQ. 12s into the sample, you can hear the Bluetooth adaptor as it receives a file from my phone (LG Viewty KU990). The pulsing/ shuffling sound is heard as a lot of data is moved around the buses on its way to the flash storage. About 1m20s in, there are curious squeaking noises. 1m48s: this is the Viewty, not the Hx4700 - I moved the pickup. The Viewty can be heard until 2m30s.

hx4700_2.wav: more electromagnetic radiation from the iPAQ. At 1m11s, the clicking sound of the touchscreen's audio feedback can be heard.

hx4700_and_KU990.wav: more Viewty and hx4700 noises: transmission of another Bluetooth file and WLAN stuff.

lg_l1915s_monitor.wav: the buzz of a computer monitor.

me.wav: my head doesn't emit much radiation; I moved the pickup around a bit, to see if I had any Borg implants - I was disappointed to find that I don't.

quartz_clock.wav: click.. click.. click.. - one per second.

sl-5500.wav: Sharp SL5500 ('Collie') running OpenZaurus 3.5.4 and GPE. Much LCD and clock noise here.

sl-c860.wav: Sharp SL-C860, running Angstrom 2008.1 from an SD card, with kexecboot. The buzzing sound is the LCD.

talking_clock.wav: my faithful old London Clock Company talking clock, with its strange rooster sound and irritating music. I never use the music because it is guaranteed to wake me up in a bad mood. The rooster works brilliantly though: I wake up one minute before it is due to crow, turn the alarm off and go back to sleep. I have had this clock for a long time (1997?) and the buttons are starting to fail.

tosa.wav: Sharp SL-6000L/Tosa, loading the IBM 'Multimodal' version of the Opera browser. I love this application, and I consider it to be the 'killer app' for this machine. Quite why IBM dropped it, I don't know - I love being able to tell it that I want a pizza with anchovies, mushrooms and whatever, and it ticks the gadgets and says 'thank you for your order'. If only it would bring me the pizza! Note, you cannot hear what I say into the microphone, when I 'order' the pizza. Another sample of me is heard here, where I say 'and I.. er.. went to the bathroom..' .. '.. and I booted the tumble- dryer into operation'. Fascinating. I was talking about a couple of recordings that I made in the bathroom - running a tap, or something.

wrt54g.wav: the noise emitted by a Linksys WRT54G, running OpenWRT Linux.
