The Olympus DS 40 digital voice recorder is an excellent recorder. It's sensitivity to the recorded voice gives an impression to a listener as if the speaker is actually speaking right on the recorder's mic. Whether the voice is recorded using Stereo or Mono, the produced sound quality is surprisingly good even though a lesser chosen quality is used to record sounds.
This digital recorder has the capability to slow down playback speed in order to listen to proper pronounciation of words from the speaker. The recorder can also do a fast playback, but I just don't see the point of this function.
This recorder has a digital flash memory of 512 MB, which allows to record sounds in extra high quality for 8 hours and so (see manual). The reason I bought the 512MB version of this recorder was that I wanted to record the speakers voice in extra high quality which would last at most 8 hours. Although it allows me to record for a longer period of time in extra high quality, one must be aware that in this quality the recorder would use more memory. In other words, for a recording period of 2 hours and 40 minutes, this recording occupies around 170 MB (megabytes). Therefore, lots of memory taken already from the recorder.
Also, the recorder has noice cancelling functions but it would distort a little bit of the speakers voice because the recorder is filtering some frequency components of the sound and thus it would take the frequency component belonging to the voice as well. Only a little distortion and you can still listen to the voice/sound well enough to understand a human speech.
In overall, the Olympus DS 40 digital voice recorder is surprisingly small, surprisingly sensitive to sounds, very good sound quality in XHQ (I haven't tried other lower recording modes), surprisingly good sound quality even at the HQ mono recording mode.
The price is expensive, but for this you get what you paid for.
