Audio and sounds files


Here are audio files related to pulsars. They were recorded at Jodrell Bank Observatory.

You will find on this page recordings of QSOs worked by radio amateurs, including with ISS, the sound of different transmission modes and interferences, as well as recordings of historical events.

You will find on this page recordings related to astronautic events, transmissions from satellite and other spacecrafts, as well as reports from astronauts and cosmonauts on orbit.

A normal pulsar, PSR 0329+54, rotating with a period near 0.715 s or 1.4 rotation/s. Recorded at Jodrell Bank

325 KB

The pulsar, PSR 0950+08-0, rotating with a period of 0.253 s. Recorded with the NRAO 92-m radiotelescope at 410 MHz

155 KB

The Vela pulsar PSR 0833-45, remnant of a supernova, rotating with a period of 89.3 ms or 11 times a second. Recorded at Jodrell Bank

165 KB

The famous Crab pulsar, PSR B0531+21, rotating with a period of 33.42 ms or 30 times a second. This is the remnant of a supernova that exploded in 1054 A.D. The pulsar is still visible as a faint star of magnitude 16 at center of M1 nebula. Recorded at Jodrell Bank

A millisecond pulsar, PSR J0437-4715 rotating with a period of 5.75 ms or 174 times a second ! This an old pulsar which has been spun up by the accretion of material from a binary companion star as it expands in its red giant phase. Recorded at Jodrell Bank

The fastest millisecond pulsar, PSR 1937+21 rotating with a period of 1.56 ms or 641 times a second. The surface of this star is moving at about 1/7 of the velocity of light ! Its FFT shows the period (~657 Hz). Recorded at Jodrell Bank, FTT by T.Lombry.

16 among the 22 millisecond pulsars discovered in the globular cluster 47 Tucanae. Their period is ranging between 2 and 8 ms. Recorded at Jodrell Bank

843 KB

A sequence of the pulsar sounds discovered in 47 Tuc as they sound due to intensity variation caused by scintillation. Recorded at Jodrell Bank

The pulsar CP0834, rotating with a period of 1.2738 s. Recorded at Arecibo at 111 MHz. An example of weak signal good for DSP.

Pattern of an individual pulse (in theory 1.56ms or 623 Hz) of PSR 1937+21. Signal processed with AVS and Audacity. For more info about this microstructure see Jodrell Bank. To not confuse with a false pattern as below.

False pattern identified in an individual pulse (89.3 ms) of PSR 0833-45 recorded at Jodrell Bank. Signal processed with AVS. Together, the compressed audio file (.AU format) and this cheap DSP program introduced some "artificial" artifacts during processing (similar to patterns that we can see in a compressed JPG image) that are not related to the sampling or the quality of the raw data. This can easily be seen by doing an FFT using Adobe Audition (ex-Cool Edit Pro) or even MatLab.
