Hi I'm looking for some simple video editing software (preferably free) that allows you to slow down a video clip, slowing down both the audio and video Windo. Nov 17, 2010 Using Sonar to slow down audio tracks from CDs I'd like to use Sonar to slow down audio tracks to figure out leads. I've imported the wav file from a CD but when I try to change the BPM it just shrinks the tracks but plays it back at the same speed.
I need a program (with an easy learning curve) that lets me slow down mp3 (at the very least this format) music and audiobook files. The software needs to be able to slow down the audio at the chosen speeds without altering the pitch and accuracy of the words being pronounced. Perhaps like the language software 'Byki Deluxe's' 'SlowSound' feature? I'm learning a foreign language (German) and I find the speeds at which the books are being read too fast. I need to hear the pronunciation of each word much more clearly to learn how to pronounce the words myself.
Is there such a product out there? Now, I know you can slow down stuff in VLC but it sounds really artificial. I need something that slows down audio files without altering the accuracy of the words being pronounced.
It doesn't have to be freeware; ease of use and quality is more important to me.
Win 7 64-bit. IE 8.
Edit: Are there any software-for-pay like Audacity? Only the beta works in Win 7. Also, I'd prefer to be able to slow down a file live and not have to create a new file to use the feature.

As Raystafarian notes, audacity has a feature called Change Tempo which promises to change the tempo of the recording without adjusting the pitch. I assume this is the effect you're looking for.
Please note that (as soandos noted in the comments) this does in no way generate a more detailed recording. The recorded information is constant, this just changes how it is played back (and, thus, can make a recording sound slower).

For further reading, there's also the Wikipedia article on Audio timescale-pitch modification.
If you don't like audacity, this feature isn't exclusive to that application. There are even Winamp plugins that can do this. I'm pretty sure there are several more options.

For a purpose-built program to do exactly that, check Express Scribe Transcription Software from NCH Software. The free version handles MP3 and other formats. The first feature on the feature list is 'Variable speed playback (constant pitch)'. My daughter uses it for her translation and transcription business. Very simple user interface, because it's not intended for all the things that Audacity & GoldWave are designed to do.

GoldWave also has the feature of slowing without pitch change, and allows for much manuel control of the process, more control than needed most times. the item is called 'Time Warp' found in the effects menu.
It also will do batching of layers of filtering and manipulations of the sound, so you could do a bunch of sound files the same way. it works in windows 7 without a single crash ever, but I am using the older 32bit version (5.06).
It has instant realtime previewing of filters, so it could be used to listen slower, without changing anything, like all realtime changes it requires cpu speed.
it is not free, only free to try. It has all the complicated stuff in it , but they didnt try and create psudo simplicity?, so I find it is easier to use than other software.
many of the 'pro' video programs now have the features of slowing the video and slowing the audio without pitch change, if it was a video that your trying to slow down. They are far from free :-)

Sony Digital Voice Editor has the feature you're looking for. It is free and flawless.

Use Corel VideoStudio, any version you have access to. This software is largely for working on video files but also has some features to slow down audio files.
I've already worked with this software for slowing down movies to learn languages.

Try using Winamp and the 'Pacemaker' (http://www.surina.net/pacemaker/download.html) plugin. You can change the 'tempo' and this will help stretch the time without any distortion. Superb!
Note: Since Winamp is not currently downloadable from it's own website (due to change in ownership from AOL to radionomy), you can download it from http://winampplugins.co.uk/Winamp/ for now.

Windows comes with an app that does this already: Windows Media Player. Just start playing your audio, and then right click inside the player. Select Enhancements -->Play speed settings.
You will see a popup, which will let you slow down or speed up your media:
Move the slider to the left to slow down play speed. Move the slider to the right to speed up play speed. This is all done in real-time, so no new files are created.
