## Arguments

- *server*

  Specifies the connection to the audio server.

- *source*

  Specifies the input device to use.

- *gain*

  Specifies the gain for the input device.

- *num\_samples*

  Specifies the number of samples to record.

- *mode*

  Specifies the line mode for the input device. Currently the following line modes are defined: **AuDeviceInputModeNone**, **AuDeviceInputModeLineIn**, **AuDeviceInputModeMicrophone**.

- *sound\_data*

  Specifies the sound information.

- *flow*

  If non-NULL, returns the flow ID.

- *volume\_mult\_elem*

  Accord to the comment in the source, not implemented.

- *status*

  If non-NULL, flush the output buffer and return the status from the server.

## Description

**AuSoundRecord** creates a flow to record audio from *source* to any destination and returns a pointer to the event handler created or NULL if there was an error. The *sound\_data* structure contains the necessary information about the audio format and the data handling function.

## Errors

**AuBadDevice**.
