Has anyone else experienced bad audio on all recordings? I'm hearing a loud repetitive sound no matter the gain nor sample rate. It is a constant repetitive thud/static/propeller/synthesizer modulation sound. Audio is being recorded, but the electronic synth sound drowns out quite a bit of it.
I'm assuming either a bad part or a mistake in the soldering? Does anyone have suggestions on how to fix it?
I have included an audio sample below...
Thank you very much for this information, I will change the batteries before using them again this month. Is there anything I can do to avoid the noise due to the temperature?
