Devel branch problem with recordings #87

Open GarryCZ opened 7 months ago

GarryCZ commented 7 months ago

Hey, thanks for the great work. I have a problem here, I have one SDR running with frequencies: frequency range start: 152.000 kHz, stop: 154.000 kHz, sample rate: 002.048 kHz, fft: 0 frequency range start: 446.000 kHz, stop: 448.000 kHz, sample rate: 002.048 kHz, fft: 0 Spectrograms are generated , but when there is a broadcast, they are drawn on the spectrogram, but no wav is created with the recording. And after 8 minutes it completely stops generating spectrograms and even after restart it doesn't continue writing spectrograms. it just gets stuck.

Here is my log: https://pastebin.com/mRXbraFH

thank you very much!

One more thing, if I take out the VHF and leave just one : frequency range start: 446.000 kHz, stop: 448.000 kHz, sample rate: 002.048 kHz, fft: 0 That works, it creates a wav. But the wav is unintelligible, it's completely broken.

I already solved the broken sound , I had to reduce the grouping size from 10000Hz to 1000Hz, it was hitting the frequency wrong , this solved the problem with the broken wav. But still the problem persists with multiple freq range on one sdr device.
