Hi, has anyone ever worked with the sound module WTV20?
I have the module on the Arduino Nano and it works so far, but I have the problem any manual to load on the SD card sounds fails with me or whenever I play something does not come out what it should actually, but any sounds. According to the data sheet, the thing can play WAV and not just AD4 files. But I have not found a solution with how much KHZ and bit the WAV file should be so that the sound “sounds normal”
The 2GB card is FAT formatted. With a test file from the network works the whole wonderful. Only I somehow do not get it to create a suitable file. I wanted to convert an MP3 file into an AD4 file, but somehow there’s the worm in it.
Does anyone have a tip? Many Thanks!
