There are hundreds of soundcards available from dozens of manufacturers. While we cannot test all of them for compatibility with VoxPro, the list below describes some of the most popular audio devices in use today.

Please note that VoxPro requires a WDM/DirectSound-compatible driver. VoxPro does not support the ASIO interface.


Audio Science (ASI) 

www.audioscience.com – Top of the line soundcards with excellent audio quality, widely used in the broadcast industry.   The ASI5211 is recommended for small-footprint and rack-mount computers with PCI Express slots. 

Digigram 

www.digigram.com – High-quality but tempermental audio cards widely used in the broadcast industry. The VX222 and VX222v2 are popular in radio stations. Some users may need to disable their on-board sound device (i.e. the audio chipset on the motherboard) in the system BIOS setup before the VX222 will work properly in digital mode. Be sure you select the WDM driver and not the one labeled "VX222 Out#1".

The VX222 works best with VoxPro if the card's latency is set to its lowest value.  Open the Digigram Control Center to the VXSetup tab to adjust this setting. 

Note on the VX222e (the PCI Express version): Users have reported that the current driver does not work with VoxPro on Windows 7 -- specifically, that VoxPro is unable to initialize the capture (recording) interface to the card.  However, rolling back to HR-Runtime 1.72k (Feb. 2011) fixes the problem.  That version is available on the Digigram website, in the driver archives.

Digigram also sells laptop "pocket" versions of their cards, the PCXPocket-440 and the VXPocket-440. These cards do not have DirectSound drivers and cannot be used with VoxPro.


Echo Mia 

www.echoaudio.com – Earlier compatibility problems with DirectSound have been cleared up with the latest driver version, though there are still reports of spurious injection of noise when recording in monophonic format (stereo recording is quite clean). Several studios are using this card in an all-digital environment, though engineers should be prepared to handle connections through RCA jacks that double as a S/PDIF interface.

Another issue that you might encounter is an apparent inability to play back after recording. This is most likely due to a setting in the Echo Mia Console: the "synchronize wave devices" option should be unchecked. (To access this option, click on the "Settings" button on the front of the Echo Mia Console, and select the "Driver" tab.)

Henry Engineering USB Matchbox 

www.henryeng.com – A great outboard interface from the folks at Henry, this is probably the best-sounding USB interface you'll find on the market.  Versatile design with balanced XLR inputs and outputs.   The only downside is that the device occasionally needs to be reset (for example, after a Windows update, or an extended sleep cycle).  Since there is no power switch, this means unplugging, then replugging.

Lexicon Alpha

www.lexiconpro.com – Lexicon has a full line of USB and Firewire audio interfaces.  We've heard that the inexpensive Alpha works fine with VoxPro5.   

Lynx Studio 

www.lynxstudio.com – The Lynx TWO card works very well with VoxPro on both XP and Windows 7 platforms.  The Lynx ONE card works well on XP, but because there is no WDM driver available for it, it cannot be used on Windows 7 machines. 

Creative SoundBlaster 

www.soundblaster.com – The SoundBlaster Live! and Audigy are probably the most common soundcards on the planet. Both are entirely compatible with VoxPro as long as you have their latest WDM (DirectSound compatible) driver installed, and you don't mind the comsumer-grade sound quality and unbalanced I/O.

The monitor control (used to prevent the jock's microphone input from being heard over the studio cue system) on the Audigy IIZS is well hidden: in the Windows recording mixer, click the Advanced button for the Analog Mix control. In the window that pops up, unselect the "record without monitoring" option. It does not work to mute the line-in (or mic) control in the playback mixer, because on the Audigy II this has the unfortunate effect of muting the input to the record destination as well. 

M-Audio 

www.midiman.com – The M-Audio Delta-44 and Delta-66 are popular consumer-quality soundcards. Balanced analog input/output using 1/4" TRS. There is a critical software switch that must be set correctly for this card to function: open the M-Audio control panel, select the "Hardware Settings" tab, find the box labelled "Multitrack Driver Devices", and select the "Independent" option. If the default "Single and In-Sync" option is selected your computer may freeze after the card is used once.  

For users needing an inexpensive outboard device, the M-Audio MobilePre USB works reliably.

SoundMax 

www.soundmax.com – Not really a soundcard – SoundMax is the audio chipset found on the motherboard of many older computers. While the audio quality is not the highest, the drivers work just fine with VoxPro.

Realtek HD 

www.soundmax.com – The Realtek HD chipset implements Intel's High Definition Audio standard for PCs and has supplanted the SoundMax as the most common on-board audio device in newer computers. It works just fine with VoxPro.

Turtle Beach Santa Cruz 

www.turtlebeach.com – A fine card for those on a budget. Analog input/output is via unbalanced mini-phone jacks.
