GBT Pulsar Observations in Audio Format

A collection of GBT pulsar observations are presented as plots and 4 seconds of audio ("AU")format. The 4 second long audio segments are rendered based on the average folded (via "prepfold") GBT observation. The pulsar period is accurately measured and the audio segment is generated by duplicating the pulsar sound for a total of 4 seconds duration. (Ignore the short sound glitches at the beginning and end of each recording.)

For 0329+54, the audio sound is also generated based on a longer, un-averaged time series. Notice that the pulsar intensity fades and returns fairly quickly.

Unix users "play" the audio segments with: /usr/bin/play

Future Developments

More pulsar sequences will be added as time permits.
