Enum FileSizeOption

pub enum FileSizeOption {
    NeverLargerThan4GB,
    AllowLargerThan4GB,
    ForceUse4GBFormat,
}

• These options are used to specify what type of WAV file you want to create.

Variants

NeverLargerThan4GB

• You specify the WAV file will never be larger than 4 GB. If the WAV file is about to exceed 4 GB and you continue to write data into it, errors occur.
• This kind of WAV file is the most common one, most of the WAV parser supports this format.

AllowLargerThan4GB

• You specify the WAV file allowed to be larger than 4 GB. If the WAV file finally exceeds 4 GB, the WaveWriter will turn this file into an RF64 file rather than the common RIFF file.
• When the WAV file does not exceed 4 GB, a JUNK chunk as a placeholder appears after the WAVE flag starting from the RIFF chunk, followed by the fmt chunk.

ForceUse4GBFormat

• The WAV file is created as an RF64 file. Some of the WAV parsers couldn’t recognize the RF64 chunk as they only know the RIFF chunk.
• A ds64 chunk is followed by the WAVE flag, the ds64 chunk uses a 64-bit field to describe the actual file size, thus the WAV file can exceed the 4 GB boundary.
