Using the Audio tab
This tab allows you to set different characteristics the project uses to handle the audio.
Opening existing projects
1. From the File menu, choose Open. The Open dialog appears.
2. Choose a drive and folder from the Look in drop-down list.
3. Select a file in the browse window or type a name in the File name box. Detailed information about the
selected file appears at the bottom of the dialog box.
4. Choose a file type from the Files of type drop-down list to limit the files displayed in the dialog box.
5. Click Open.
Note: If ACID is unable to locate one of the media files
when you open an ACID project, you can choose to leave the
media offline and continue to edit events on the track. The
events point to the location of the source media file. If you
restore the source media file at a later time, the project opens
normally.
Opening ACID projects with embedded media
When you open an .acd-zip project, the project file and all media files are copied to the temporary files
folder.
Note: You can customize the location of the temporary files
folder. For more information, see Using the General tab on
page 179.
Any changes you make to the project are saved to the files in this temporary folder until you save the .acd-zip
file again. For more information, see Saving projects on page 53.
Item Description
Master bus mode Choose either Stereo for a standard audio project or 5.1 Surround for a surround
project.
Number of additional stereo busses Enter the number of stereo busses that you want in your project. You may add up to 26
busses. The busses appear in the Mixer window.
For more information, see Using busses
on page 111
.
Sample rate Choose a sample rate from the drop-down list or enter your own rate. The sample rate
range is 2,000 Hz to 192,000 Hz. Higher sample rates result in better quality sound,
but also mean larger audio files.
Bit depth Choose a bit depth from the drop-down list. A higher bit depth results in better quality
sound, but also means larger audio files.
Enable low-pass filter on LFE Select this check box to limit the audio sent to the LFE channel in a 5.1 surround project.
For more information, see Working with 5.1 Surround on page 157 .
Cutoff frequency for low-pass filter Enter a low-pass cutoff frequency value for 5.1 surround projects. ACID limits audio sent
to the LFE channel to frequencies lower than the value you enter. Applying a low-pass
filter approximates the bass-management system in a 5.1 decoder and ensures that
you’re sending only low-frequency audio to the LFE channel.
Low-pass filter quality Choose a setting from the drop-down list to determine the sharpness of the low-pass
filter’s rolloff curve. Best produces the sharpest curve.
Start all new projects with these
settings
Select this check box if your project requirements do not change or you want consistent
settings for future projects.
