Hy Pip....most of the poems I have been playing around with have come up at around 350 to 450ish kb, and thats up to three four lined (8 syllabled) stanzas.
That's recording with 11,000kHz mono....it has given the clearest recording, with a smallish file size, and loaded each time without any difficult (using Sound Recorder facilities). What are you using, as Tony is not having much success with attaching his file, yet can post on another board.
Great to see you have posted already though, Zy
