- USB Audio Card abilities

As we said earlier, the Hercules DJ console can also be used as an external sound card with high-level specifications:

• Sampling up to 16-bit/48KHz in WDM mode.
• 24-bit/96KHz ADC and DAC.

There are 2 sampling modes:

• WDM sampling: hardware sampling up to 16-bit/48KHz; other formats (24-bit/96KHz) are software interpolation.
• ASIO 2.0 sampling: 2 input/4 output hardware sampling at 24-bit/48KHz; 2 input/6 output at16-bit/48KHz..

According to Hercules, the ASIO 2.0 latency is between 5 and 6ms.

When using ASIO 2.0 drivers, your are restricted to using only 48KHz and no 44KHz. Hercules explains that "...The USB audio clock is close to 48KHz, so files sampled at 48KHz are played directly via USB while files sampled at 44KHz are over-sampled at 48KHz by the CPU to play via USB, which increases the latency for 44KHz files. Considering that the latency via USB for 44.1KHz files is not much better in ASIO 2 than in WDM mode, while ASIO 2 has a latency benefit at 48KHz, we have determined that WDM drivers are sufficient for 44.1KHz files..."
