Metadata settings

Compatibility metatags with iTunes

iTunes use especial id3 format. When the option is checked, AuI ConverteR save and export metadata in this format for WAV, AIFF.


Force unknown chunks or tags (for some software possible troubles)

WAV, AIFF formats are capable to store various data blocks (chunks). According to these formats' requirements, if an application can't recognize the format, the program skip the chunk. If a software (player, editor) or hardrare (player) have issues with displaying some metadata, artwork or converted file cause opening inability, turn either ON or OFF the option to achieve successful work with file.


Force 32-bit WAV (ON - long files possible truncated, not recommended)

Conventional WAV file contains 32-bit variable, that describe length of audio data. It is 4 GBytes.

But sometimes, higher length is requered. Especially, high resolution audio files consume larger data size.

To solving the isuue, AuI ConverteR implement RF64 standard and workflow processing of size-expanded WAV files.

However, it can cause compatibility issues with some audio tools. If the issues are there: in Settings > Metadata > check "Force 32-bit WAV (ON - long files possible truncated, not recommended)" switch. However, it can cause overflow of aforementioned audio data length variable, when size of converted music file exceed 4 GBytes.


No markers RF64

AuI ConverteR supports WAV RF64 (WAV with size more 4 GBytes). Its workflow require reserve space for RF64-markers. To avoid it, in Settings > Metadata > check "No markers RF64" switch.


No meta tags id3, flac,... (track name, album, performer, etc., not recommended)

Some audio hardware and software may have an issues with metadata (song name, performer, artwork, etc.). Or you're need audio file without the metadata.
To avoid writing metadata into converted file, in Settings > Metadata > check "No meta tags id3, flac,... (track name, album, performer, etc., not recommended)" switch.


No all chunks (data blocks) except ID3 (WAV, AIFF)
