# NNS_SndStrmSetChannelPan

## C Specification

      #include <nnsys/snd.h>

      void NNS_SndStrmSetChannelPan(
      NNSSndStrm* stream,
      int chNo,
      int pan );

## Arguments

`stream` | Pointer to a stream structure.
`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 stream's channel pan. The default pan value is 64 (center).

The channel number `chNo` is the channel that is in the current stream. The channel number `chNo` value is not directly related to the channel number that is mounted in the NITRO sound circuit. For example, if you allocate two channels with the `NNS_SndStrmAllocChannel` function, the first channel will be channel number 0, and the second channel will be channel number 1.
