the after Thanksgiving edition of the Blind Flight

Hello.

I hope everyone who celebrated it had a happy Thanksgiving.

in keeping with a tradition I began back in 2008 when I first started broadcasting, I will be playing 3 hours of acoustic music to bring in the quiet reflective season ahead.

I’ll be playing tracks by such artists as Peter Kater, Paul Avgerinos, Robert Rich, Tom Caufield, Robert Linton, Paul Adams, Kathryn Kaye, Evan Wish, All India Radio, Leigh Ann Phillips and Josh Johnston.

please join me for a late night of quiet contemplative music, starting at 11 PM on November 29th on stillstream.com/

Thanks for listening.

new release with Mystified: A Night on Pluto

Hello.

I have another release on the treetrunk net label, this time, with Mystified.

Here are the liner notes and the download link for the album.

"When Mystified made his pluto120 drone available for people to use in their own compositions, I decided to create a long-form ambient piece using this drone as the basic element of the track. I added some winter night sounds I found on freesound.org and clarinet improvisations which I created on the Ensoniq TS-12 synthesizer. I felt that the clarinet was an instrument that could express the mood I was going for, something very cold and remote, two elements which define what, at one time, was the smallest planet in our Solar System.

I’d like to thank Thomas Park for the use of the drone and for making this available for download and hope you enjoy the music.

Thanks for listening."

exploring space on Friday’s Blind Flight

Hi there.

I couldn’t really decide what to do on this week’s show so I’m going with an old stand by theme, the exploration of space.

I’ll be starting out the program with my newest release, Jupiter is a Cosmic Vacuum Cleaner.

I’ll also guide you in a voyage beyond the 5 planets and we’ll end up exploring the gas Giant, Neptune. Along the way, we’ll hear strains of sound as played by Mystified.

I hope you’ll join me on Friday November 22, starting at 11 PM for another exploration of space by way of ambient sound.

Thanks for listening on www.stillstream.com/

new release: Jupiter Is A Cosmic Vacuum Cleaner

Jupiter is a Cosmic Vacuum Cleaner

This dark ambient work was inspired by an astronomical event that occurred during the week of July 16th through the 22nd, 1994, where fragments of a comet called Shoemaker Levy 9 slammed into Jupiter.

Besides my Ensoniq TS12 synthesizer, I also incorporated the sounds of Jupiter, though mangled a bit as explained a bit later.

You can find the video and audio referenced in the following description at http://www-pw.physics.uiowa.edu/voyager/v2pws_jupiter_arrival.html

Here’s some information on how these signals were recorded as taken from the above citation itself.

Voyager PWS VOYAGER-2 PWS:

ARRIVAL AT JUPITER

The PWS plasma wave instrument on Voyager 2 recorded these signals as the spacecraft was approaching Jupiter on July 2, 1979, between 15:56 and 16:45 spacecraft event time (essentially UTC), near the bow shock in front of the planet’s immense magnetosphere. A variety of plasma wave phenomena heralded our arrival, including Langmuir waves, ion acoustic waves, and others. These are the authentic "sounds of Jupiter" unmodified and presented at their original frequency.

The PWS wideband waveform instruments on the two Voyager spacecraft sample the electric field on the dipole wire antenna at a rate of 28800 4-bit samples per second, using an automatic gain control. Consequently, the audio is just slightly better than telephone quality. Packets of 1600 samples are acquired, separated by the equivalent of 128 missing samples. Running these packets together results in the playback taking less than real-time (by a factor of 1600 / 1728), and also introduces a slight audible flutter. The amplitudes at the edges of these packets have been smoothed to reduce this flutter, but this is the only modification to the signal.

These are by no means the only "sounds" that Jupiter makes, but there is nice variety during this hour interval. All of the available measurements during this interval are present but since there are time gaps, the total run time is approximately 27 minutes.

Some of the audible features unfortunately are the result of onboard interference. The constant tone at 2.4kHz is caused by the spacecraft power supply. The occasional sound like someone pounding a bass drum is the result of spacecraft attitude thruster firings. The sound more like thumping on an oil barrel that tends to occur about 7 seconds into each frame, but sometimes more frequently at a regular cadence, is due to a stepper motor on another instrument. The tones with harmonics that build slowly and end abruptly and appear as multiple horizontal lines in the spectrogram are due to the grid modulation of another instrument. The rest of the signals are the naturally-occurring plasma waves that this Voyager instrument was designed to detect: These are the genuine "sounds of Jupiter".

Now, what do we mean by "sounds of Jupiter"? First, the sounds are not typically produced at the planet itself, but in the magnetosphere, the magnetic bubble surrounding the planet. In this particular case, most of the signals are generated from the interaction of the supersonic solar wind colliding with the bow shock ahead of Jupiter’s magnetosphere. These waves are not the same as the pressure waves in the atmosphere that we normally think of as sound. However, they do have some similarities. Even though space is an excellent vacuum, it is "filled" with particles at a density of typically a few to several hundred particles per cubic centimeter near planets. Most of these are charged and constitute what we call plasma. Being charged, these particles interact with each other without the need to "collide" as they do in the atmosphere. Moving charged particles both produce electromagnetic fields and waves and also are moved by electromagnetic fields and waves generated elsewhere. These are "plasma waves". Many of these interactions occur at frequencies that are audible to humans. This doesn’t mean that a human ear could hear them in space — the pressures are far too small — but it is conceivable that an ultra-sensitive microphone could measure them. In practice, however, it is far easier to measure the oscillations in the accompanying electric and magnetic fields with antennas, and that is just what we do. To produce sound we can hear, we simply do the moral equivalent of hooking our antennas up to an amplifier in order to drive speakers. Plasma waves can be considered "space audio".

The video shows a series of 48-second-wide spectrograms with an animated cursor that shows the time of the audio track. The amplitude of the signals is color coded with dark blue for the weakest and red for the strongest signals. Low frequencies are at the bottom of the plot and high frequencies are at the top. Time ranges from left to right.

note about processing:

Though I used the original signals from the audio of this project, I did introduce some delay and reverb to give the sound a darker feel which I felt blended nicely into what I had already composed for the piece.

I hope you enjoy the music and thanks for listening.
