pythonでgnuradio その3

#概要

pythonでgnuradioやってみた。
サイン波を録音。

#サンプルコード

from gnuradio import gr
from gnuradio import blocks
from gnuradio import analog

class my_top_block(gr.top_block):
	def __init__(self):
		gr.top_block.__init__(self)
		samples = sample_rate = 48000
		ampl = 0.3
		src = analog.sig_source_f(sample_rate, analog.GR_SIN_WAVE, 440, ampl)
		head = blocks.head(gr.sizeof_float, samples)
		dst = blocks.wavfile_sink("a1.wav", 1, sample_rate, 8)
		self.connect(src, head, (dst, 0))

if __name__ == '__main__':
	try:
		my_top_block().run()
	except KeyboardInterrupt:
		pass

以上。
