Three Questions: 1. What's the easiest way to create a loop wav from a wav file with 4 beats and a little extra at the end if you know the tempo?

Any way of doing it for the whole bunch of files together? 3. If I have a wav rythm track, is there any way of finding the tempo at which it's been played? Again, it's for some files recorded from midi whose tempo I don't know and which I can't record again. Can I take a minute of the song and find the tempo at which it's been played?

Hello Sonic Founders and everyone else here,

(my first post here.. except for a little one back somewhere; it was
getting
rather awkward asking ACID questions in the cakewalk newsgroups!)

Three Questions:

1.
What's the easiest way to create a loop wav from a wav file with 4
beats and
a little extra at the end if you know the tempo? What's the easiest
way to
do this with a bunch of files?

i.e. if I record a midi drum loop as an audio file at 96 bpm and
instead of
stopping at the perfect end of the 4 beats it stops a little further.
So I
get a wav file a little longer than the loop.

I know I can do it with an audio editing program a file at a time, but
I
have a lot of these files which can't be recorded again, any
easy/quick.eficient way to do it; any way of doing this for all the
files
together?

2.
I have a bunch of files ACID propertied as hard-disk based rather
than
loop-base playing. So I have to convert them to loop based a file at a
time,
when I use them. Any way of doing it for the whole bunch of files
together?

3.
If I have a wav rythm track, is there any way of finding the tempo at
which
it's been played? Again, it's for some files recorded from midi
whose tempo
I don't know and which I can't record again. Can I take a minute of
the song
and find the tempo at which it's been played? I need to find this to
chop up
loops from the wav (it would make it much easier) , and also to use it
with
some other midi/audio softwares.

Thx,
Neole
