Sorry jo 77, you have obviously misunderstood me. The orginal sound clips on the site were .wav files with MP3 extensions (but still .wav files nonetheless - the process made them more compact, apart from anything else, whilst not degrading the sound too much ) & I have now also put up MP3 files; to do this I resampled the wave files at 44100, & then converted them to .MP3.
What people could or couldn't hear them on originally depended on what facilities they had on their computer, & what their default players were. Ir may be that someone with an older version of Media player will have a problem with the .wav files as they are, if so & they post & let me know, I can always put them on as ordinary 16-bit signed versions.
