Description 

Audio device type

Choose a driver type from the drop-down list: 

•  Microsoft Sound Mapper: The default setting. Allows the Sound Mapper to 

choose an appropriate playback device. 

•  Direct Sound Surround Mapper: Allows the Surround Mapper to choose 

appropriate playback devices for the front, rear, and center/LFE channels in a 
5.1 surround project 

•  Windows Classic Wave Driver: Allows you to choose a specific audio device 

using a classic wave driver. For stereo projects, choose a device from the 
Default Stereo and Front playback device drop-down list. For 5.1-surround 
projects, choose devices from the Default Stereo and Front playback device, 
Default Rear playback device, and Default Center and LFE playback device 
drop-down lists. 

•  ASIO: Allows you to choose a specific audio device using a low-latency ASIO 

driver. For stereo projects, choose a device from the Default Stereo and Front 
playback device from the drop-down list. For 5.1-surround projects, choose 
devices from the Default Stereo and Front playback device, Default Rear 
playback device, and Default Center and LFE playback device drop-down lists. 

•  ReWire Device Driver: Allows you to use ACID software as ReWire device in a 

ReWire mixer application. If a ReWire mixer application starts ACID software, 
that ACID window will start in ReWire mode and cannot be switched from 
ReWire mode. If a ReWire mixer connects to an existing ACID window, that 
window will run in ReWire mode, and you can switch out of ReWire mode if 
necessary. If you exit that instance of the software and start ACID software 
again, the new instance will start ReWire mode, and you can switch out of 
ReWire mode if necessary by choosing a different audio device type. 

Default Stereo and Front playback  Choose the device that you want to use for playing stereo sound data. In a 5.1 
device

surround project, this device plays the right and left channels. 

Selecting a device such as the Microsoft Sound Mapper allows Windows to select 
an appropriate device to use for the current sound data. 

Default Rear playback device 

Choose the device that you want to use for playing the rear channels (right 
surround and left surround) in a 5.1 surround project. 

Default Center and LFE playback 

Choose the device that you want to use for playing the center and LFE channels in 

device 

a 5.1 surround project. 

Playback buffering (seconds) 

The Playback buffering (seconds) slider specifies the total amount of buffering 
that is used during playback. The larger the number, the more buffering that 
occurs during playback. This value should be as low as possible without gapping. 
To set it, start at 25 and play a typical song. Move some of the track faders. If the 
playback gaps at all, try increasing this slider in small increments until the gapping 
stops. As you increase this slider, the RAM meter at the bottom of the ACID 
window will indicate more RAM usage. 

If you simply cannot get playback to be free of gapping, you need to either 
decrease the number of tracks you are trying to play simultaneously, install more 
RAM in your computer so you can increase buffering, buy a faster access hard 
drive, or minimize the number of audio plug-ins you are trying to use 
simultaneously. 

Enable track buffering 

Select this check box and drag the Track buffering slider if you want to adjust the 
amount of audio that is prerendered ahead of the cursor position. 

When the check box is selected, a separate processing thread is used to render 
audio from tracks. On multiprocessor or multicore computers, a thread will be 
created for each logical processor. 

When the check box is cleared, a single processing thread is used to render audio 
from tracks and busses. 

Default audio recording device 

Choose the device that you want to use for recording sound data. 

Selecting the Microsoft Sound Mapper allows the operating system to select an 
appropriate device to use for the current sound data.
