The SD card that comes with your Audio BAC is prepared at the factory with the correct file system, but if you need to prepare another card, it should be formatted with the FAT16 or FAT32 file system only.
Do not use NTFS or exFAT, and do not store files on your card other than audio files intended for playback via the BAC. Many SD cards ship from the factory with an exFAT file syste
WarningThe act of formatting a storage card erases all data on it permanently. Before formatting your card, back up any files on it that you wish to save.
Exercise special caution when formatting your storage card to ensure you don’t accidentally format the wrong device – if you aren’t careful, you could accidentally format other external storage devices or even your computer’s secondary hard disk or recovery partition. When in doubt, stop and consult your operating system manual for assistance.
Files should be named with short filenames – 8 characters or less with a 3 character extension. We recommend simple numbers (for example, 001.wav).
The Audio BAC supports .WAV, .MP3, .OGG, .AAC and .WMA file formats. We recommend the industry-standard 44100Hz 16-bit stereo .WAV format for shorter sounds and 192Kbps CBR MP3 for longer sounds, but most sample rates and formats should work well.
