## Detailed Description

STK audio file output class.

This class provides output support for various audio file formats.

FileWrite writes samples to an audio file. It supports multi-channel data.

FileWrite currently supports uncompressed WAV, AIFF, AIFC, SND (AU), MAT-file (Matlab), and STK RAW file formats. Signed integer (8-, 16-, and 32-bit) and floating- point (32- and 64-bit) data types are supported. STK RAW files use 16-bit integers by definition. MAT-files will always be written as 64-bit floats. If a data type specification does not match the specified file type, the data type will automatically be modified. Compressed data types are not supported.

## Constructor & Destructor Documentation

stk::FileWrite::FileWrite | ( | std::string | fileName,
|  | unsigned int | nChannels = `1`,
|  | FILE_TYPE | type = `FILE_WAV`,
|  | Stk::StkFormat | format = `STK_SINT16` |
| ) |  |  |

Overloaded constructor used to specify a file name, type, and data format with this object.

An StkError is thrown for invalid argument values or if an error occurs when initializing the output file.

## Member Function Documentation

void stk::FileWrite::open | ( | std::string | fileName,
|  | unsigned int | nChannels = `1`,
|  | FileWrite::FILE_TYPE | type = `FILE_WAV`,
|  | Stk::StkFormat | format = `STK_SINT16` |
| ) |  |  |

Create a file of the specified type and name and output samples to it in the given data format.

An StkError is thrown for invalid argument values or if an error occurs when initializing the output file.

void stk::FileWrite::write | ( | StkFrames & | buffer | ) |

Write sample frames from the StkFrames object to the file.

An StkError will be thrown if the number of channels in the StkFrames argument does not agree with the number of channels specified when opening the file.
