B0531+21 (The Crab)

P = 0.033 s

B0531+21_430MHz_FFT.wav

B0531+21_1170MHz.wav

B0531+21_1170MHz_FFT.wav

The Crab pulsar emits giant pulses, which are easily audible in the .wav files. The FFT.wav files bring out the periodic emission. 
B0540+23

P = 0.246 s

B0540+23_ALFA_FFT.wav A weaker pulsar, you can just hear its "thumping" amid the noise.
B1933+16

P = 0.359 s

B1933+16_ALFA.wav One of the brightest known pulsars--every pulse is audible.
B1937+21 (Original MSP)

P = 0.00156 s

B1937+21_1475MHz.wav

B1937+21_1475MHz_FFT.wav

Because of its extremely short period, this pulsar is audible as a tone. Can you discern the same tone in both sound files?
B2020+28

P = 0.343 s

B2020+28_1475MHz.wav

B2020+28_1475MHz_RFI.wav

B2020+28_1475MHz_FFT.wav

A bright pulsar, most individual pulses are audible. There is also some RFI near the end of the second sound file.
