output auto-mute
When set, an output signal is muted when recording is stopped, re-
stricting program audio from being sent to listeners “between takes.”
output delay
A digital delay applied at the output. Signal delay is often set at an
output to compensate for the delay introduced by digital imaging
systems so that picture and sound remain in correct “lip sync”. Output
delay is set in either frames or milliseconds.
Files and Recording
exFAT
A storage volume format that can be read and written from current
versions of MacOS and Windows. exFat supports volume sizes up to
128 PB (gigantic), and individual les can have a maximum size of 16
EB (even more gigantic, bigger than the maximum volume size).
le list
Every le recorded by a recorder is visible in the le list. It can be
viewed either on a recorder or from a computer when the recording
volume is mounted. The le list shows all the individual les recorded
by a recorder.
take list
Separate from a le list, a take list consolidates related les such
as a group of monophonic WAV les generated by a single take and
presents them as a single take.
WAV File
A universal, well-supported le type for sound le recordings. WAV les
can contain one or more (up to 65,535) tracks of PCM audio data at
any sampling rate and bit depth. A standard WAV le is limited to a
maximum le size of 4 GB. Sound Devices uses the .WAV extension
for recorded les, including for les with Broadcast WAV metadata and
WAV RF64 les.
broadcast WAV, BWAV
Broadcast WAV les are WAV les with additional, non-audio data,
such as bEXT chunk data. Broadcast WAV les offer timecode sup-
port.
WAV RF64
An extension of the WAV le type that supports le sizes larger than 4
GB. When recording high track count, high sampling rate polyphonic
WAV les, the 4 GB size limitation of WAV can be reached quickly.
RF64 les larger than 4 GB require recording to a volume type than
can support le sizes larger than 4 GB.
monophonic WAV
A WAV le that is comprised of a single track of audio. When recording
multi-track audio with monophonic WAV les each track is recorded
to its own WAV le, with a le name indicating the track number. All
associated monophonic les that are part of a multi-track recording
will be identical lengths.
polyphonic WAV
An individual WAV le that contains multiple audio tracks. When
recording multi-track audio with polyphonic WAV les, all recorded
tracks are contained within a single WAV le.
isolated track
A recorded track of an individual microphone or sound source. “Iso”
recordings allow for post-record mixing of individual sound elements.
mix track
A recorded track that is a sum of multiple tracks. In production sound
the mix track is often a single summed track of all production dialog
elements. Mix tracks can also be sub-mixes of like microphones, such
as a sub mix of just lavalier microphones or just boom microphones.
track arm
Tracks that are active and ready for recording are said to be “armed”.
When recording begins all armed tracks begin recording. Depending
on the production it may be advantageous to arm and disarm tracks,
especially to disarm unused tracks.
bext chunk
Broadcast WAV extension data added to the audio data in a WAV le.
The bext chunk includes timecode and user bit data. For systems
that do not recognize the bext chunk, this additional information is
ignored.
iXML
An extensible data schema for audio and related metadata stored
in broadcast WAV les. Manufacturer-specic data generated during
recording is stored in iXML.
scene
On Sound Devices recorders the scene becomes part of the le
name for a take. Scene names can be pre-loaded to quickly change
between scenes.
take
A recorded take is an individual recorded le (or les when recording
monophonic WAV les) generated by a recorder. Take numbers are au-
to-incrementing. Take numbers are added to the end of the le name.
track name
Individual tracks of a multi-track recording can be named to indicate
microphone type or character name.
notes (metadata)
A metadata eld that is saved along with audio data in a recorded
sound le, useful for sound report generation. Some workstation
software recognizes the notes eld and presents it when viewing the
sound le.
phrase
A pre-set text string which can be used to quickly ll out the notes
eld.
circled take
An identifying character, the @ symbol, which is placed in the le
name to highlight a take. Circled takes can either be used to identify
good takes or to identify tracks or takes that will be ignored.
