If you have large body of audio (an Assimil or Linguaphone type chunk of 60-120 minues) that you've studied to the
point of knowing every nook and cranny... why not try one extra kink before considering it exhausted. As well as editing the audio to remove any ostensibly "helpful" blank noise on the tape, why not play with the options on your software and speed it up a bit? My software doesn't let you do this without making the audio go all "chipmunk"-y, but this isn't all too bad. It at least makes for a novel challenge. Just to compare, I chipmunked up some audio of my native language that I had lying around, and after a bit of experimentation I found that a doubling of speed (200% speed) was odd at first - but entirely listenable. Pushing this to 250% became difficult, and I doubt I could handle this sort of speed if the material was entirely fresh. So I made a big fat mp3 of my Linguaphone audiobook and put the speed to 150%. As much as I treasure this course, the audio is quite slowly spoken even in the final lesson, so this speed more or less brought it up to the speed of the 1960s Assimi course for German. That is to say, a natural speed. The result for the Linguaphone lesson at 150% was that the later lessons were at a slight speed above natural speech, and the earlier were bumped up to more or less ordinary speed. So I've been listening twice weekly to this edited tape - now reduced from 2hrs to 90minutes - just as I have been, but with the added practice of speed and the convenience of less time spent. I'm now bumping it up to 175% up from the original speed. In conclusion, I recommend this method to those of you who have thoroughly digested the contents of a book with accompanying audio, and know that audio intimately. You should feel secure that there is no realistic rate of speech that is beyond you with the structures and vocabulary that you know. And of course this also does exactly the same job as reviewing the material, which you'd be doing anyway - and all in less time, to boot.

Do you mean "change tempo"? This butchers the audio, whereas in "Chipmunk mode" at least
everything is in the same fidelity as the original, only occupying less space in time. That aside, I've just discovered that Audacity has a tool which renders my many hours of audio editing as as good as wasted: "Truncate Silence" immediately clips out any silence longer than x milliseconds. Gah. 1 person has voted this message useful | |||

yeah, I can speed it up to about 125%, more than that and the audio will sound unnatural

If it works for you, great. Personally, I wouldn't go to the trouble for what would amount to negligible gain, if any, since I already know "every nook and cranny". I'd rather spend the time watching a movie I've not seen or read a book I've not read and test my comprehension level that way. R. == 2 persons have voted this message useful | |||

Is it that bad? I've heard that slowing down more than 30% is bad, but I've not tried speeding up. I guess you can also "chipmunk" with audacity, using the other option, but don't know what the quality is like. ... BTW, if anyone is still using an old version of Audacity, they should check out the download site, as there was a new version this year (2.0.3). 1 person has voted this message useful | |||

I found that if you play with the "truncate silence" option you can keep the same pitch but speed up the syllables. It's a bit choppy but it works. I've used both the speed-up affect and this extreme truncation and turned out a new, shorter file of my audio. 1 person has voted this message useful |
