Important Sound Setup Information
When you first start Mixcraft, you should make sure that the audio latency response is set up properly.  All sound devices and sound cards are not created equal and some have better performance than others.  In addition, your computer's speed will make a difference in audio performance.  Adjusting your sound device's performance will be a balancing act between latency versus gapping or breaks in continuous sound.  

If you are recording audio with Mixcraft's built in monitoring or playing virtual instruments, you will definitely need to adjust your latency response properly.

Choosing An Audio Driver Type
1. Click "Preferences" from the "File" menu. 

2. Click on the "Sound Device" tab.

3. For Vista and Windows 7 users, the default choice is "WaveRT".  If you have a slower computer, you may need to adjust the latency to a higher value.  (1000 milliseconds = 1 second.)  WaveRT is recommended if you have Vista.  If "WaveRT" is enabled, click it.  (WaveRT stands for Wave Real Time.)   In standard mode, WaveRT goes down to 20 milliseconds latency.  

4. If you have Windows 7, you may be able to click WaveRT "Exclusive Mode".  This mode will allow you to go down to one millisecond of latency, depending on your computer's speed and power.  Note that in this mode, other programs will lose audio capability while you run Mixcraft.  You may need to restart the other programs to get their audio back.  WaveRT exclusive mode is advantageous for those seeking to use every last ounce of power out of their computer, but at the same time other programs will cease to make audio during WaveRT Exclusive Mode.

5. If you don't have WaveRT, the next best option is "ASIO".  If available, click "ASIO".  If it is grayed out, go to your sound device or sound card manufacturer's website and install the latest drivers. Click on the "ASIO Device" and choose the sound device or sound card you wish to use.   You can adjust the settings of the ASIO device by clicking "Open Mixer".  Each ASIO driver is implemented differently and so you will have to consult the manual or help for your sound device in order to adjust the latency response.  Make sure that the "Default Output (Playback)" is set to the correct device so that you will hear audio properly. 

6. If you don't have Vista or an ASIO option enabled, you have to use the last option "Wave".  Click the "Wave" radio button.  To reduce latency, decrease the "Number Of Buffers" and reduce the "Buffer Size".  As you adjust these fields, the "Latency" field will update.  You will have to make adjustments, click "OK" and play some audio.  100 milliseconds or less is tolerable.  20 milliseconds or less is preferred.  

Computer Speed Consideration
If you have a slower computer, you may need to adjust your latency to be longer in order to avoid gapping or breaks in the audio.  If you are hearing breaks in the audio, you will need increase your latency.  Alternatively, you may need to purchase a higher performance sound device or sound card designed with music recording and playback in mind.  Changing the latency will depend on what type of audio driver you are using.  See the section above on "Choosing An Audio Driver Type" for more information.  Another good speed enhancement is to de-fragment your hard drive.

Shutting Down Unnecessary Software
When using Mixcraft, shut down unnecessary programs such as email, instant messaging, and your web browser.  Each additional program uses your computer's memory and CPU, and, in many cases, it will cause performance to suffer in Mixcraft.  Check the Window's task manager to see what programs are using a lot of memory or CPU usage.  On XP and Vista, you can bring up the task manager by pressing Ctrl+Alt+Delete.  If you can remember to reactivate your anti-virus software, shut down your anti-virus software while using Mixcraft. HOWEVER, DON'T FORGET TO TURN YOUR ANTI-VIRUS SOFTWARE BACK ON WHEN YOU ACCESS YOUR EMAIL OR THE INTERNET!

Get The Latest Drivers
Always make sure to have the latest drivers for your sound device in order to get the best performance and quality in your recordings!  Visit the website for your sound device or sound card to install the latest drivers.  (Even if you just purchased the device, it is very likely that the included drivers are out of date already.)
