Hi,
I've almost completed integration of MAD in alsaplayer (http://www.alsaplayer.org). My thanks go to Rob for the very informative message earlier and of course excellent work on the MAD enigne! I will probably release the first MAD powered version early next week. Sample accurate seeking is in the plugin. The nice thing is that 'scratching' mp3's is now very accurate in alsaplayer (i.e. speed control beteen -200+ and 200+ %).
Thanks again, Andy -- andy @ alsaplayer dot org
