I would like to purchase this model but need to know if I can adjust the playback speed of an MP3 Podcast file (eg., 0.5x to 2.0x without change in pitch, as is the case with my Sony Walkman I MP3 player.) I would like to place the podcast file in the folder of my choosing.

The online manual for this player states you can select the play speed during playback of an Audiobook, but doesn't specify the range of play speed and whether this is only available for audiobooks (I'm assuming the audiobooks are in MP3 format.)

Is this playback speed control available only in the audiobook folder (restricted to audiobooks only)?
