A note about digital audio drop-outs, latency and buffer sizes.
Digital audio recording and playback using a FireWire equipped computer relies on high frequency “streaming” of data
along the bi-directional FireWire connection lead. The data consists of packets or chunks of sampled audio data which is
held in buffer memory and sent to the receiver where it is then buffered again so that the receiving equipment can process
it and decode it into audio data that the receiving system can understand. This streaming process is very dependent on the
ability of the processor to handle it. The specific processor
in ZED-R is optimised for the task, but processors in com-
puters vary widely and for this reason an element of
tweaking may be required.
When the ZED-R device drivers are installed on your com-
puter, a Control Panel is also installed and should appear as
an icon on your computer desktop.
The Control Panel enables customisation of the digital au-
dio settings as well as device name changing.
If your DAW is suffering from audio drop-outs, try increas-
ing the buffer size or try a different Operation Mode.
If latency is a problem and your computer processor is fast
enough to handle it, try reducing the buffer size in Normal
Operation Mode. You may need to close your audio appli-
cation and launch it again once adjustments are made.
Changing sample rate and buffer size may cause
clicks in the audio. Remember to protect your
speakers by turning the amps down or muting the
outputs from ZED-R.
