Main software features
•
Real-time, simultaneous record and playback in PCM (8, 16 and 24 bits)
as well as in MPEG Audio Layer I, Layer II and Layer III
L
, Float IEEE754
conversion supported (with 24-bit fixed-point dynamic range)
•
When using the np SDK, real-time mixing of several PCM and MPEG
audio streams, direct monitoring, level adjustment, panning, cross-fades,
punch-in/punch-out, scrubbing, time-stretching, pitch-shifting, 3-band

MPEG Layer III play-only on DSP;
MPEG Layer III recording on the host computer is available through
Digigram's PC Codec option using the np SDK
Note: the HR Runtime package for Windows Vista does not include a Wave driver. In
