I'm using Audacity to create sound bytes, but the most recent one I've created isn't uploading. I have it set to 44.1 MHz, 16-bit, mono, less than 10 seconds AND it's a .wav file... But whenever I try to upload it to SL, I keep getting the message "File does not appear to be a supported sample rate (must be 44.1k)." I'm so confused... Any advice?
