'fraid I'm impelled to offer some un-perl-ish solutions, after viewing your issues with most of the replies below

I'm infering/guessing that you want to have the system more or less resemble the operations of old-tyme cassete dictation (eg, to replace something: Stop (NOT pause), rewind, find start of erroneous section, cue to just before, re-start recording....). Might you consider writing a perl wrapper for controls around two different audio packages (one for *n*x, including tiger10) and one for 'doze?

• Con: two audio packages (both, however, mp3 or similar and selection transparent to user); cost if you use OSS proprietary for the audio
• Pro: Coding minimized (though some would consider that a con).

Aare you doing this mostly for the challenge/bragging rights? (I'm not implying 'fault' if so; but ignore the rest of this.)
Why not go with direct speech to text? Someone -- usually clerical -- is going to have to proofread/re-listen to the saved audio to get it anywhere near the dictator's intent.

Or, let the dictator resume/continue use of dictaphone, cassette, or electro-mechanical device (if s/he can't cope with complexities of "re-winding" digital audio or a text file) and feed output to a speech-to-text package required ONLY on a single OS, shared by clerical folks.

Sometimes, it's a good idea to just find a way to make something work, when the help offered doesn't fit.
