kAudioFileInvalidPacketOffsetError = 'pck?'
An unspecified error has occurred.
The file type is not supported.
The data format is not supported by this file type.
The property is not supported.
The size of the property data was not correct.
The operation violated the file permissions. For example, an attempt was made to write to a file opened with the kAudioFileReadPermission constant.
The chunks following the audio data chunk are preventing the extension of the audio data chunk. To write more data, you must optimize the file.
Either the chunk does not exist in the file or it is not supported by the file.
The file offset was too large for the file type. The AIFF and WAVE file format types have 32-bit file size limits.
The file is malformed, or otherwise not a valid instance of an audio file of its type.
The operation cannot be performed. For example, setting the kAudioFilePropertyAudioDataByteCount constant to increase the size of the audio data in a file is not a supported operation. Write the data instead.
The file is closed.
End of file.
Invalid file position.
File not found.
