Noise - cmd aplay #492

Closed baudev closed 11 months ago

baudev commented 1 year ago

I notice that the cmd aplay command (with a .wav audio file present on the camera) makes a strange noise at the beginning and end of the audio file.
This noise is also present when the camera says "WZ initializing" when installing wz_mini.

However, the camera does not make this strange noise if you use only the Wyze firmware. Does anyone know where it comes from?

Thanks

i've noticed this varies by device, some do, and some don't. could it be power supply related?

@baudev Try a file, not in wav format, but raw pcm s16le 16000hz mono, and no noise should happen.

gtxaspec commented 11 months ago

confirmed, playing raw pcm files without the wav header eliminated the click

converted all sounds to raw pcm https://github.com/gtxaspec/wz_mini_hacks/commit/6cda362ee84350e8b3df62e64f22b485be80c16f
