2. Acquiring Audio Data from VN-E4 via HTTP _ 2.2. API Format

Structure

Unlike parameter acquisition/setting, Accept line is not required. Basic authentication is also not necessary.

Example GET /api/audio?assured=1&lowdelay=0 HTTP/1.1<CRLF>

Host: 138.198.34.250<CRLF><CRLF>

Parameter values are indicated using =. Do not insert space before and after =.

Example assured=1

Parameters are segmented using &. Do not insert space before and after &.

Example assured=1&lowdelay=0

There is no need to specify all parameters. Default values will be used for parameters that are not specified.

Parameter Description

assured VN-E4 temporarily saves up to 2.5 seconds of the compressed data. Specify as assured=0 to request for the

latest data that is temporarily saved and assured=1 to request for the oldest data. Specify as assured=0 to

shorten the audio delay time. To enable stable playback in a network where jitter occurs, it is recommended

that this be specified as assured=1. Default value is 1.

lowdelay Specifying as lowdelay=1 disables the Nagle algorithm of TCP, and audio delay time will be shortened. When

lowdelay=0 is specified, the Nagle algorithm is enabled and audio delay time will be prolonged. However,

transmission overhead will be enhanced. Default value is 1.
