Hello tony,
It records in 192KB/s mono Wav format, perfect for speech, with 2GB capacity,
24 hours of continuous recording. The speaker gives out a surprising amount of
bass for such a small unit. There is now the Micro-Speak Plus, with the same
features but with 4GB capacity, giving you 48 hours of recording. The only
downsides are the short time between charges, 4 hours, and the battery is
non-replaceable.
Hope this helps.
Best wishes,
Clive Pallett
