.FLAC
Free Lossless Audio Codec is a lossless data compression algorithm specifically designed for au-
dio. It is a convenient way to extend recording time with no effect on audio quality. It is suitable for
recording and archiving. FLAC, in particular, offers data compression rates that range anywhere
between 30% and 60%, depending on the audio program. Sound Devices Wave Agent Classic (www.
waveagent.com ) is a free Windows based software used to extract FLAC to WAV as well as combin-
ing monophonic files and splitting polyphonic files.
What to consider when recording FLAC:
• notes are currently disabled, all other metadata is stored
• limits your sampling rate to 96 kHz
• limits recording to only one storage medium at a time
• The 7-Series can play back the recorded FLAC files.
• Use Sound Devices Wave Agent Classic software (www.waveagent.com) to extract Broadcast
Wave files from 7-Series recorded FLAC files.
• Auto save feature does not apply to FLAC files, if power is lost while recording the file maybe
invalid.
.MP2
MPEG-1 Layer II is a lossy compression algorithm often used for speech recording.
What to consider when recording to MP2:
• time code is enabled (with BEXT or iXML data)
• mono recordings are not allowed with bit rates above 192k
• limits your input routing to inputs 1 and 2 and tracks A and B only
• limits your sampling rate to 48 kHz
• limits your bit depth to 16 bit
• limits recording to only one storage medium at a time
.MP3
MPEG-1 Layer III is a lossy compression algorithm often used for music.
What to consider when recording to MP3:
• time code is enabled (no BEXT or iXML data)
• limits your input routing to inputs 1 and 2 and tracks A and B only
• limits your sampling rate to 48 kHz
• limits your bit depth to 16 bit
• limits recording to only one storage medium at a time
• Auto save feature does not apply to MP3 files, if power is lost during recording the file maybe
invalid.
