Thanks for listening everyone! Much appreciated.
It plays fine on my Samsung tablet. Is it possible that there's a problem playing the file on Apple devices? The only thing I did differently from normal, was open the wav file in my workstation and save it as an MP3 from there. Usually, I convert files using dedicated conversion software. I'd be surprised if it made any difference, but just in case, I've uploaded the file again, converted to MP3 using the conversion software. Could someone let me know if it plays OK now. Thanks.
By the way, in a note to mods, the embedded player on the site has not worked at all on my tablet for a long time. I always have to download files to listen to them. Is there any chance this can be rectified?
