I certainly miss the subjective recording sound quality comparison to Resco Audio Recorder (
http://www.resco-net.com/audiorec_indepth.asp) and NoteM (
http://www.zavorine.net/wince/mp3.htm) in the article, mainly because, so far, no MP3 recorder could achieve the recording quality (in 44 kHz, mono, 56/112 kbps mode) of NoteM. Fortunately, the latest VITO release changed this all. Still, a lot of users, unhappy with previous VITO releases, may have skipped the new release because of the past of the product.
I've tested all the three new programs (Resco, Vito and, of course, NoteM) thoroughly; my experience is as follows.
The MP3 encoder in the latest Resco Audio Recorder still lacks in the tremble area - it sounds as it was a telephone conversation -, even with 96-192 kbps recording modes. Furthermore, it is useless with OGG encoding even on quick PDA's like the iPAQ 2210 (400 MHz XScale PXA255 processors running on WM2003) because it simply requires way too much processing power. The other Resco encoders are pretty lousy too: Speex only supports 32 kHz as the maximal sampling frequency. Futhermore, its power consumption is some 45% more than that of NoteM.
VITO's Sound Explorer, up to now, was certainly even worse because of the reduced recording capabilities of the built-in MP3 encoder (11 kHz maximal sampling frequency up to until the latest version). Fortunately, this version allows for using 44 kHz and high bitrates too.
The subjective sound quality of VITO's Sound Explorer is almost as good as that of NoteM. The one and only problem with it is that it requires even more battery power than Resco's latest MP3 recorder. In some cases (e.g., several hours long recording on battery power), this may render the application useless.
