speed control for audio playback of speech available now or planned? (please say Yes)

[gregrice]

My first inquiry - thanks Stefan - longtime user of your powerful tool! 8-D

I'm happy IrfanView can play audio at double speed, but I find no plug-in or option to auto-adjust the frequency-range of speech that permits somewhat normal sound, when played back at speeds faster than normal.

I listen to recorded audio-book and spoken word audio playback at double normal speed.
A time-saver - and it helps squeeze in more Ideas Per Minute into my little head.
(I'm surprised that MS Windows Media Player offers this as a standard feature - though it doesn't function on all audio file formats, apparently).

Does anyone have any suggestions for freeware or opensource tools for this? Ideally for IrfanView.

thanks for your help,

Greg

I was unaware that Windows Media Player did that - is it really a standard feature or part of a plug-in?
I have always used the Change Tempo effect in Audacity to do it. You can apply it to the whole track although it is more commonly applied to just a selected part.
