The ASIO driver (sound card) can be selected using Jamulus under the Windows operating system. If the selected ASIO
|
||||||
|
driver is not valid an error message is shown and the previous valid driver is selected. Under the Mac operating
|
||||||
|
system the input and output hardware can be selected.

#### Input/output channel mapping

In case the selected sound card device offers more than one input or output channel, the _Input Channel Mapping
|
||||||
|
and Ouptut Channel Mapping_ settings are visible. For each Jamulus input/output channel (left and right channel)
|
||||||
|
a different actual sound card channel can be selected.

#### Buffer delay

![Buffer delay](src/res/homepage/bufferdelay.png)
|

|
|
||||||
|
The buffer delay setting is a fundamental setting of the Jamulus software. This setting has influence on many
|
||||||
|
connection properties. Three buffer sizes are supported:
|
||||||
|
|
||||||
|
- 128 samples: This is the preferred setting since it gives lowest latency but does not work with all sound cards.
|
||||||
|
- 256 samples: This setting should work on most of the available sound cards.
|
||||||
|
- 512 samples: This setting should only be used if only a very slow computer or a slow internet connection is available.
|
||||||
|
|
||||||
|
Some sound card driver do not allow the buffer delay to be changed from within the Jamulus software.
|
||||||
|
In this case the buffer delay setting is disabled. To change the actual buffer delay,
|
||||||
|
this setting has to be changed in the sound card driver. On Windows, press the ASIO Setup button to open
|
||||||
|
the driver settings panel.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
On Linux, use the Jack configuration tool to change the buffer size.
|
||||||
|
|
||||||
|
The actual buffer delay has influence on the connection status, the current upload rate and the overall delay.
|
||||||
|
The lower the buffer size, the higher the probability of red light in the status indicator (drop outs) and the
|
||||||
|
higher the upload rate and the lower the overall delay.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
The buffer setting is therefore a trade-off between audio quality and overall delay.
