Main question: What is the encoding used for wav files? Unsigned PCM 8-bit, or is it another type? Context: I accidentally formatted my sd card with data I had yet to download. I was able to recover using a recovery wizard (Recuva), but my files are now corrupted. They have the same file size, but most audio players give an error message about a missing codec. I found a suggestion to change to a RAW format and import into Audacity. Using the defaults this works and I can barely hear recorded sounds but only through a significant amount of white noise. This indicates the the data is there. (I had downloaded about half of the data - 9 days of recording - before some technical glitches, so all was not lost, but it would be nice to get the full dataset back.) The default file specification in Audacity is: Encoding: Unsigned 8-bit PCM Byte order: Little-endian Start offset: 0 bytes Sample rate: 44100 Hz Are these the correct file properties for AudioMoth wav files?

I am running out of my budgeted funds and am feeling the SD card costs. Its only a couple more hundred, but... its money I don't really have. There are some 32gb speed class 10 SanDisk sd cards, that are not on the recommended list, but are more than half the price of the recommended (7 USD compared with 15 USD). Any cautionary tales out there? I could obviously test them out, but I feel like I would need to test several of them and for long periods of time which I don't have the luxury to do. I am looking at this one in particular. https://www.amazon.com/SanDisk-Ultra-microSDXC-Memory-Adapter/dp/B073JWXGNT/ And recording at 48kHz.

I need to tell a funder the approximate time of shipment to our door for the next round. The GroupGets description says factory lead time of early April, but do you think that means we'll start receiving in late April/early May, or does that mean GroupGets will need several weeks of turnaround time and we are looking at late May time frame?
