My pc crashed on me last night during a new podcast, and i'll be f***ed if im gonna rebuild 48 minutes of a pc from 6 second chunks of temp files with audacity, as it takes HOURS!!! Anyone know of a program that can do it quicker???

If your temp files are plain raw wav data, you may merge the chunks with a copy command from console. Something like:

Code: Select all

COPY part1 + part2 + part3 + part4 targetfile
where part1, part2, part3 are your temp files and targetfile the big chunk resulting from the merge.
This is stil tedious work but faster then loading every single bit into audacity and when copy-paste-save-or-whatever.


This could also work with already encoded mp3 chunks but as I tried that some time ago, it randomly failed.

use the /b switch to make sure the files are copied in Binary format like this.

Code: Select all

copy /b file1.tmp +file2.tmp +file3.tmp Podcast.mp3
or:

Code: Select all

copy /b *.tmp Podcast.mp3

Oops! Thanks, Analog-X! I forgot about the /b-switch, which is vital for success here. :shock:

I'm not sure about the wildcard in your second example, but it would be great as it would spare him a lot of steps.

Yes the wildcard does work... I should have maybe gone into a bit more detail and mention as well, that when using the wildcard...

It helps if the fragmented files are named sequentially i.e. file1 file2 file3 etc..

also you dont want any unwanted files in the folder when using wild card otherwise it will merge them as well.

I used to write a lot of DOS scripts to make things like this easier... its been a while.

That would also take too long as there are over 1000 temp files, all in wav format!!!

Dunno if that format has headers or compression. You may be out of luck then. Maybe you have to record the show a second time. :shock:

The Montage capability in Wavelab will do this, since it has the ability to import files onto a track and stack them one after the other.

If you send me all the bits I can have a stab at it for you.

Not a problem for Wavelab. Stick it on a DVD and send it over.
