Audacity Forum

When I use Audacity 1.3.6 to record from my turntable, I can export to MP3 , but although a file with .mp3 extension results, it does not seem to be a real mp3 file. It keeps the Audacity icon in front of it and when I copy it to my MP3 player, it is on the SDHC card, but the player does not find it...
