![]() For example, 44 100 samples per second can be expressed as either 44 100 Hz, or 44.1 kHz.īandwidth is the difference between the highest and lowest frequencies carried in an audio stream. Sample rate is the number of samples of audio carried per second, measured in Hz or kHz (one kHz being 1 000 Hz). ![]() This in turn allows me to assign these I/O ports independently as needed for recording or playback, and gives me the ability to record more tracks simultaneously as opposed to the limitations of my computer sound card which only provide two-channel (stereo) audio I/O.Īnother advantage is higher audio fidelity since an unmixed ASIO output is "bit identical" or "bit transparent", that is, the bits sent to the sound card are identical to those of the original source. The ASIO driver allows Reaper to "see" all of UX2's inputs and outputs. Latency is the delay between an application sending audio information and it being reproduced by the sound card, or input signals from the sound card being available to the application. What does that mean for me? Lower latency. I found out that by using ASIO, Reaper is able to bypass the normal Windows O/S audio paths and connect directly to the UX2's sound card. The user guide recommends using ASIO for good reason. It allows software to have access to the multi-channel capabilities of a wide range of powerful sound cards. ASIO (Audio Stream Input/Output), developed by Steinberg, is a cross-platform, multi-channel audio transfer protocol that is being adopted by many of the manufacturers of audio/MIDI sequencing applications.
