Geek Singer asks: "I've had classical singing lessons for a while now and managed to advance to a level where hearing my own lessons is important for developing my skills. Here in Europe many singers use MiniDisc recorders. As a geek I think that MD recorders are DRM-encumbered, clumsy, slow and obsolete. Especially moving the recordings into my computer can get very troublesome due to nasty restrictions cast by Sony. For these reasons I need to have something else than a MD recorder. There are various portable MP3 players that have a voice recording capability, but I've found none that have all the properties I need: low price, good recording quality, line-in recording, excellent battery life, a good interface, support for Linux or Mac OS X and enough space for tens of hours of decent quality voice recordings or a slot for an exchangeable memory card. I've already checked numerous manufacturers including iRiver. Their players are great, except that the HD-models are too expensive and the flash-based models don't have a memory card slot. What portable digital voice recorders do you suggest?"
