Which format does the "audio file" hav? MP3, wav, flac, wma? Is 4GB the size of the file or of the expanded data? Is it 4.00GB or the 4,294,967,295 Bytes limit of a FAT32 formated disk?

If you can store a 5GB file on the disk, the disk cannot be formated in FAT32. This means, that the limit is caused by the file format or the function, which imports the file. See https://en.wikipedia.org/wiki/WAV :
The WAV format is limited to files that are less than 4 GiB, because of its use of a 32-bitt unsigned integer to record the file size header.
The W64 format solves this problem, but it cannot be opened from all programs. See https://en.wikipedia.org/wiki/RF64
