PC Audio Instructions for USB Audio - links for free S/W
USB instructions:

The USB that Empirical Audio installs is based upon the M-Audio Transit
hardware. It uses the Transit drivers. Load the transit drivers from the
CDROM included. Then plug-in the USB cable provided. A small ICON will
appear on your lower toolbar momentarily when the hardware is recognized.
A digital signal will commense as soon as the cable is plugged in, so your
DAC should sync to this. Sometimes this signal is interrupted by certain
user actions, such as stopping a track mid-way and double clicking on
another track. In these cases, you must unplug the USB cable at either
end and reconnect to get sync again. In the lower toolbar is an ICON for
M-Audio Transit. This is the Transit driver control panel. It allows you to
select the sample rate. The following allows you to select between
16-bit/44.1 kHz or 24-bit/96 kHz (192 kHz is not supported):

16/44.1 setting: 2 in, 2 out, 16-bit, 8000 Hz to 4800 Hz

24/96 setting: 0 in, 2 out, 24-bit, 88200 Hz to 9600 Hz

We found the 96 kHz setting to the be best.

*Recommended Player and Ripper software:
PC-driven audio is better than ever. The Foobar2000 player and Exact Audio
Copy (EAC) ripper make it practically foolproof to make exact error-free CD
copies on hard-disk and play them back. The quality of playback is superb
using Peter Pawlowski's Foobar2000 and there are lots of features and
plug-ins available for formatting, data-base use and look-and-feel. Here are
the links to download the basic tools for free:

*Driver Plug-ins
If you are using Windows XP, then the audio is routed through a DSP software
called "Windows Kmixer". This mucks-up the sound, so it is best to bypass this
mixer. To accomplish this, use plug-ins called ASIO or ASIO4ALL. These can
be downloaded for free from:

ASIO4ALL plug-in download site:



ASIO plug-in downloads:

foo_ddecontrol_029.zip Ver. 0.29 for foobar2000 Ver. 0.8.2 (52KB)

foo_output_asio(dll)_041.zip (dll version) Ver. 0.41 for foobar2000 Ver. 0.8.2 (404KB)

foo_output_asio(exe)_044.zip (exe version) Ver. 0.44 for foobar2000 Ver. 0.8.2 (526KB)

ASIO master page (Japanese):


ASIO files must be download and unzipped. Then put the .dll file (and exe if you got
that version) into your Foobar2000 plugin folder and re-start Foobar2000. Then go to
preferences, output and select ASIO. Then go to ASIO panel and select the right
hardware driver. If your hardware prefers the data to be INT32SB, then select 24 bit
in Foobar2000 preferences, playback, padded to 32 bits and turn off the dithering.


ASIO, Foobar2000 and the control panel for the Transport driver all have buffering
size and number options. We have not determined the best configuration for these
in 16 and 24-bit modes yet, but we will update this section when we do. We have
noticed that the wrong buffer settings for 16-bit can delay the start of a track and
you loose that music, or in 24-bit mode, a long playlist will start to have ticks and
pops in the later tracks.
