Clipping and Renaming wavesink output file
Hi,
I have created a FM receiver using GNU and the output is fed to an audio
sink to listen live and to a wavefile sink to record. There was no option
to edit the recording time in GUI, so I edited the python code to record
and rename the file every 5 mins. But the problem is only the first file
has data and other files are created but with no data.The code i've written
for this as follows:
*def create_new_file(self):*
*current_time = datetime.datetime.now()elapsed_time = current_time
- self.start_timeif elapsed_time.total_seconds() >= REC_TIME_SEC:
self.blocks_wavfile_sink_0.close()filename =
'E:\\Record\\{}.mp3'.format(current_time.strftime("%Y%m%d_%H%M%S"))
self.blocks_wavfile_sink_0 = blocks.wavfile_sink(filename, 1, 48000,
8)self.start_time = current_timedef
check_and_create_file(self):current_time = datetime.datetime.now()
elapsed_time = current_time - self.start_timeif
elapsed_time.total_seconds() >= REC_TIME_SEC:
self.create_new_file()def work(self, input_items,
output_items):current_time = datetime.datetime.now()
elapsed_time = current_time - self.start_time
self.total_items_written+=len(output_items[0])# Call
create_new_file multiple times if enough time has elapsedif
elapsed_time.total_seconds() >= REC_TIME_SEC:
self.create_new_file()current_time = datetime.datetime.now()
elapsed_time = current_time - self.start_time return
len(output_items[0])*
Thank you in advance..
Re: How to run the program without showing the block diagram in windows 10?
I tried executing the python file but it keeps showing errors. I'm new to this and with my limited knowledge I've set the paths. This is the error that keeps popping up everytime. *C:\GNURadio-3.8>python NBFM.pyTraceback (most recent call last): File "C:\GNURadio-3.8\NBFM.py", line 23, in import gnuradioModuleNotFoundError: No module named 'gnuradio' * *Also thank you for your help*.

How to run the program without showing the block diagram in windows 10?
I have done a project for my internship using gnu radio. I want to run my project on another pc(windows 10) and show the output but not the block diagram .My invigilator should only see the output. Can anyone suggest a way to do this?
