Audio File Type
selects the type of audio files to be recorded.

•
BWF
is the EBU standard audio file based upon the WAV file format. It requires finalization at the
end of recording. The Session record engine will automatically convert the file to a RF64 (64-bit
Wave file) if the file size exceeds 4 GB. It supports timestamping and standardized metadata. BWF
is the current de facto standard professional PCM audio file format.
Most current audio software supports RF64 files, but some older products do not; if
you will be working with older software it would be safest to use the Auto-break feature
to keep files under 2GB.
•
AIFF
file type is the standard Apple Audio file. It requires finalization at the end of recording and
has a 2 GB filesize limit. It does not support timestamping.
“32 (float)” audio bit depth is not available for the AIFF file format.
•
FLAC (Free Lossless Audio Codec)
records lossless data-compacted audio files which can save up
to 40-50% of the file size while maintaining perfect bit-accuracy of the original audio stream. Data
reduction rates vary depending on content. With continuous music recordings, actual file size
savings are generally closer to 70% compared to uncompressed BWF or AIFF files.
Since FLAC is not a Linear PCM audio file forrmat, it is not currently supported for playback in
Session. Waveforms will be shown during capture but will be removed at the end of each take,
with the file location shown in the Missing Files UI in the Session widget bar.
“32 (float)” audio bit depth is not available for the FLAC file format.
•
Bit Depth
sets the bit depth resolution of the recorded audio files to 16- or 24-bit (integer) or 32-
bit (float). 24-bit integer is the default setting. If you select 16-bit, you should apply dither using
the MIODither plugin on the channels you will record; the RP does not automatically dither down
to 16-bit.
