Can we truncate the voice file?

[jezze_y]

Hi there,

When I record my own voice for a word, I notice there is a 0.4sec delay at the beginning because I'm not fast enough. As I'm creating a series of very fast flash card for my DD following Shichida method, is there a way I can cut out the 0.4 sec silence at the start of the file?

Thanks,
Jezze

Hi again,

Yes, you can cut off parts of your recording using the sound recording/editing program you're using. Kindly note though, that if you cut off most of the silence at the start of your recording, LR may cut off the sound during playback (this happens slightly randomly, though). This is why for the recordings in the official LR curriculum, we have included a bit of silence for everything just in case.

If you'd like to make your slides flash very fast, you can do this by turning on the Autoforward function in LR and adjusting the speed to how fast you want it to be.

To do this, go to LR's Playback screen and select your Category or Playlist (where you have the flash cards you made), then in the Play Panel at the bottom of the screen, click on the button labeled "Autoforward" so that the light turns green.
To adjust the Autoforward speed, click on the cog button right beside the Autoforward button, and in the small window that pops up, adjust the flash speed by moving the slider to the left (faster) or right (slower).

I hope this helps!

Thanks again Kezia. I've tried the autoforward and it works great. But I'd still like to try cutting the initial 0.4 sec silence at the beginning. Are you able to provide step by step how to do it?

Thanks a lot,
Jezze

Hi, sorry for not replying sooner 

I'm not sure what sound editing program you're using, but I believe doing this can be done in pretty much the same way in most programs -- just in case, the steps below apply to the Easy Voice Recorder (comes free with LR), Adobe Audition, and Audacity:
 - Open your audio file in your editing program
 - Highlight the silent (straight line) part of the sound's waveform
 - Click DELETE to cut that part off

You may notice that after saving your work and opening it again, a bit of silence was appended to the beginning/end of your file. Most editing programs do add an extra silence at the beginning and end of files by default, so in the end you may not be able to do this perfectly.

I hope this helps, though!

Thanks Kezia. Cant wait to get LR, still waiting for credit card verification for my Paypal account. Sigh...
