Subject:A question about large sound file editing

Hi:
I'm using Soundforge 4.0d. I record seminars of 45 or 50
minutes direct to disk using Soundforge on a 300 mhz
computer.

The sound files are 16 bit stereo and are usually about 500
meg, saved as a direct sound file. If I wish to delete a
couple seconds at the beginning of the file, it takes about
3 minutes and 40 seconds to recover from that one edit. Is
there a faster way?

Thanks!
Larry

Can you record mono? The file will be half the size, and not take as many resources (disk, memory) to edit. (Each edit, the file is completely rewritten, if I am not mistaken.)

I experienced a similar problem - my files, when longer than 15-17 minutes (44-16 MONO) would take 20-30 seconds per edit. Add up more than 100 edits per file, and the minutes stacked up (more than 15, in 20 second increments)

Doubling the RAM substantially reduced the waiting - to at most 8 seconds. (I now have 256K RAM, on a P II 450).

Also, if you edit from the END of the file...it's a LOT faster!!!

Another thing you might like to try (depends on whether you have a separate backup, and how crucial your previous edits have been) is to turn off undo(Ctrl U).

I wouldnt go there - but... depending on what your getting rid of
and/or your output format -just mute it. It takes no time because it
doesnt have to move that massive file down to take the deleted prtions
place in time.

If u use CD architect you can easily split the file, adjust the file
to no longer include what you want to get rid of (just drag the end
there where you split it) then slide the new shorter piece onto the
next peice and crossfade away!

For multiple edits within a long sound file I gotta say PLAYLIST -
once you get into this habit you'll never go back. (even for most butt
edits in music (trickier)- but for spoken word NO PROBLEM) just find
yourself a nice consonant to hide behind or a good strong inhale and
you're all set.
