Please help Acid guru's...

I'm having huge quality problems bringing my own recorded wav files into Acid. I'm recording bass lines and stuff into Sound Forge and they sound fine, but as soon as I bring them into Acid it makes them sound all echoed and delayed so they sound pretty bad. I've tried recording the files in mono but it makes no difference. I've also noticed if I convert the file to a 'One Shot' file so it isnt stretched or shortened it sounds fine... the trouble is as soon as you make it a 'Loop' the crappy echo kicks in and ruins it... even if the song tempo is the same as the original recorded wav file.

I am a total rookie at this and using an old version of Acid from a few years ago.

Any suggestions would be hugely appreciated

Sounds like a stretching property problem (even though it shouldn't be a problem if your wave is properly acidized and playing in the same tempo AND key). That echoey, warbling (?) effect is usually a result of playing a loop faster than its original tempo. Some sounds are more forgiving than others, but acoustics (voice, guitar, piano, etc.) can give you real problems.

Make sure your settings/acidization is correct. If you have a loop that's "120bpm" but is REALLY 119.9, that extra 10% of one bpm can throw it out of whack if the stretching properties aren't tweaked. The fact that OneShots of the same file play fine make it almost 100% definite that it's a tempo/key/properties issue.

Jess is definitely on the mark here.

ACIDizing is an art unto itself when you do it in an app like Sound Forge.

Be sure to use the ACID Loop Creation Tools to their fullest in Sound Forge. They will help you immensely if you know how to use them. (Go to View>Toolbars on Sound Forge's menu bar and check the "ACID Loop Creation Tools" toolbar.)

Don't just fly blind when recording in Sound Forge. Be sure to keep an intended tempo and number of beats per measure in mind. (Example: 118 BPM with a Loop thats 8 beats long.)

Use the Edit Tempo dialog to gauge tempo for a selection. (If no selection is made, the whole file is used.) You would use this info to ACIDize with using the Edit ACID Properties dialog.

You may also want to consider recording in ACID and editing externally in Sound Forge. If you do such a task, ACID will pass along measure info to Sound Forge, making it easier to extract what you want out of a recorded take.

You could even ACIDize right in ACID itself by soloing the track once it's recorded, place the Loop Region over the area what you want to bounce down and keep and use CTRL+M with the "render loop region only" option enabled. Overall project key and tempo info will be added (effectively ACIDizing) to the newly rendered track.

You could then tweak in Sound Forge. (Just do not change the length of the file, like deleting or adding data. As I've said, length affects determined ACIDized tempo.)

As Jess noted, you will probably want to go into the properties of the ACIDized track in ACID itself and adjust and/or add stretch markers as appropriate. (You would want markers on accented subdivisions of a beat.) Note that this feature is in ACID Pro only.

HTH,

hi :
after posting my question "How do I acidize loops" ; I read your problem.
I think my problem is similar . If I can learn anything I will try to help.

I have read about the " BEAT MARKERS" BUT I do not know anything about them or how to set them correctly. Can anyone please explain?

I don't have acid pro only acid music 3.0 and sound forge xp studio 5.0
I do have another editor that can add beat markers . Have tried that but my loops did not sound good when i was done.

I need to acidize live recorded bass and guitar samples that were rendered as to small loops as mentioned by other help post. Mine are ok if I don't change tempo ANY at all.
I have loops off of cd's that you can change 20 BPM or more??

thanks to all
charliep

Acid defaults to forced divisions at sixteenth notes. I've found that, for me, eighth note divisions or greater work better. I also only enable markers when something's being played. If a note's being held, I'll disable the markers during the hold, which cuts down on the "warbling" effect you get when you speed a loop up. Literally, just changing that forced division setting will make a huge difference, without even touch the markers. Unfortunately, you can't do it in Acid Music -- only Pro.

As far as how other programs' markers are read by Acid, I don't know.
