# NNS_SndArcStrmSetChannelPan

## C Specification

      #include <nnsys/snd.h>

      void NNS_SndArcStrmSetChannelPan(
      NNSSndStrmHandle* handle,
      int chNo,
      int pan );

## Arguments

`handle` | Pointer to a stream handle
`chNo` | The channel number
`pan` | Pan (position) value Takes values in the range of 0 (left) to 64 (center) to 127 (right)

## Return Values

None.

## Description

This function changes the channel pan of the stream that is connected to the stream handle `handle`. This function does not perform any action if the stream handle is invalid.

The channel number `chNo` is the channel number in the stream data. The channel number `chNo` value is not directly related to the channel number that is mounted in the NITRO sound circuit. For example, for stereo stream data, the left channel is channel 0 and the right channel is channel 1.

By default, monoaural data is played in the center (64) and stereo is played with channel 0 output from the left (0) and channel 1 output from the right (127). When this function is called, these default values can be changed.
