Speeding up lectures?

Hi all
Does anyone know of a program that helps you speed up lectures while adjusting pitch and also helps you save those lectures in that adjusted speed?


I just want to adjust a particular speed and then save the lectures in that speed.
is that even possible?

Thanks in advance

try Audacity (free on download.com) ...if you adjust the "tempo" the pitch doesn't get altered too much at all

HI Taus
Thanks for the reply

I tried downloading audacity1.2.6
but when i run the file it says its corrupt

which version of audacity did you use?

can i save my video lectures in a particular speed with this?

Thanks again

audacity is for audio files only

to change & save video speeds you need to re-encode the videos which will be very time consuming.

you can extract the audio from the video and change the speed, which would be quicker - but then you have no video.

So how does one speed up and save Audio?
i'll atleast try the audio

For Audio Files: try QuickTime....you can play at 1X, 1.5X, 2x...etc

For Video Files such as divx, wmv,...etc....: try PowerDVD8

Installed today the new vlc player. VLC plays everything except realplayer files. I don't know if I had some plugins preinstalled, but give this a try.
I was able to speed up some lectures until they sounded like 3 year old child.
If you don't mind the tone, you will like this.

Any time you change the speed of playback, the pitch gets changed at the same time (in my experience).

There are programs where you can increase the speed 1st, then decrease the pitch 2nd i.e. WavePad.

Unfortunately, this severely diminishes the audio quality - making the voice harsh, unhuman, and really hard to listen to.

In my experience, you should just increase the speed (and pitch) to 150% and go to work. The high-pitched voice seems annoying at first - but soon you grow accustomed to it and can listen for hours on end.

There are two keys to adjusting to voice.
1. Really pay attention to what you are listening. Your brain will be busy thinking about Klebsiella rather than the voice.
2. Take a break about every 45 minutes to one hour. After that time, your brain will tend to turn off, and your annoyance may seem to grow as you focus on the voice more, and the content less.

I used audio to study all the way throug medical school. Four years of listening to my voice sped up to 150% like a chipmunk. It very seldom bothered me.

You can find a lot of USMLE audio at ApolloAudiobooks.com.

Good luck,

Stark

you need to increase the speed
without affecting the pitch
if you increase the pitch it will sound like chipmunks

there are free winamp plugins that preserve pitch, ex:
Take It Easy
PaceMaker

may be possible to save the playback with the winamp file writter (havent used)

I tried winamp with plugins, Quicktime, and VLC. Either I got too much distortion (I usually listen at 1.5x and up) even when adjusting pitch or the programs would keep crashing. I purchased Enounce 2xAV and can't be happier. No distortion even at 2x+ speed. works with video and audio in Windows Media Player. No crashes.

I speed up my school's lecture videos with windows media player. I think it might only work with .wmv files, but you can experiment. You can either select "fast" or "slow" speed (I don't know about slow, but fast is 1.4x) or you can use the expansions menu and set it to any speed you want. the audio sounds fine; no chipmunk voices.
