Pasting a loop from Sound Forge... -ACID Product Family

Subject:Pasting a loop from Sound Forge... Posted by: u4ik Date:10/25/2001 12:42:06 AM I'm editing a loop from cd that is in my song. Basically just cutting a bit off it and put an effect on it in Sound Forge. When I save it and open it, put it in ACID...the loop is WAY slow. Completely changes tempo! It sounds fine in SoundForge though. I've done Edit Tempo, changing what I know of in ACID, no luck though...am I doing something wrong?

Let's say you want to create a selection from your file as you want to. Let's also say you want this selection to be exactly 8 beats long. Open the file up in Sound Forge and make your selection. Be sure to get the selection precisely where you want it to be. Use the transport controls to fine tune the selection. Use CTRL+C to copy and then use CTRL+E to paste the selection into a new window. You can close the original at this point. Next, use Edit Tempo and enter the exact number of beats you want the snippet to be in "Selection Length in Beats". The "Tempo in Beats per Minute" setting will tell you exactly what the tempo of the selection has to be if you want to hear it exactly as it sounds with that many beats. You must take this into account for your ACID project's tempo. So, if you enter 8 in the "Selection Length in Beats" setting and it gives you "100" in the "Tempo in Beats per Minute" field, and you next used the "Edit ACID Properties" option and entered "8" in the "Number of Beats" field and then saved, the resulting loop's tempo will be 100. Understand how it works now? If you don't like the tempo but still want the number of beats to be the same, use "Process>Time Stretch" on the menu bar and be sure to use "Tempo" under "Input format" and adjust the tempo to your liking. Click OK and save. It should sound perfectly at that tempo within ACID. HTH, Iacobus

Reply by: milomingus Date:10/29/2001 3:50:25 PM what about loops that sound funny if the tempo isnt the same....i find that many loops are like 80bpm or 100bpm....when i add loops that arent near that bpm, they sound all digitally crunched and funny, and some actually sound ok....can you explain this? thanks.

For instance, really crunchy distorted guitars sound really funky at a slower tempo than anything I've heard. (Mostly artifacts like echoes and delays) That's probably due to the way audio signal is produced (an uneven, rough waveform? Not sure as I'm not an audio engineer). For most loops, they'll sound better faster than their original tempo than slower. You can see the original tempos for all the loops in your project vs. the project's overall tempo when you click and hold/adjust the Project Tempo slider in ACID 3. Each track will have a respective horizontal indicator that appears with a percentage to the right. The center represents original tempo for that track. If the indicator's marker moves more to the left, the track is going slower than the loop's original tempo, while if the indicator's marker moves more to the right, the track is going faster than the loop's original tempo.
