The sfz Format: Basics
What is the sfz format?
The sfz format is a file format to define how a collection of samples are arragned
for performance.
The goal behind the sfz format is to provide a free, simple, minimalistic and expandable
format to arrange, distribute and use audio samples with the highest
possible quality and the highest possible performance flexibility.
A sfz format file can be played in our freeware sfz player.
Soundware, software and hardware developers can create, use and distribute the sfz
format files for free, for either free or commercial applications.
Some of the features of the sfz format are:

How is the sfz format structured?
The sfz format is a collection of sample files plus one or multiple .sfz definition
files. This structure, containing multiple files instead of a single
file is defined as non-monolithic.
Two kinds of sample files were selected to be included in the sfz format: a basic
PCM uncompressed format (standard Windows wave files) and a basic, adjustable-quality,
royalty free compressed format (ogg-vorbis encoded files).
The inclusion of a compressed format allows sample developers and soundware creators
to easily create preview or demonstration files in a small package
so they can be transferred with minimum bandwidth, while retaining complete performance
functionality.
Both formats are 100% royalty-free, so players can be created to reproduce them without
fixed or per-copy fees. They can also be freely distributed on the
web (provided that the contents of the files are copyright cleared).
Each .sfz definition file represents one or a collection of instruments. An instrument
is defined as a collection of regions. Regions include the definition
for the input controls, the samples (the wav/ogg files) and the performance parameters
to play those samples.
How is the .sfz definition file created?
A .sfz definition file is just a text file. Consequently, it can be created by using
any text editor (i.e. Notepad).
Why non-monolithic?
While both monolithic and non-monolithic formats have advantages and disadvantages,
there are several reasons which moved us to adopt a non-monolithic sample
format. Technological and conceptual reasons can hardly be separated, so here's a
basic explanation.
The most important reason is the file size limitation of a non-monolitic file on
FAT32 partitions. Samples are getting really big nowadays, with thousands
of individual samples collected in single instruments, and triggered according to
many input control combinations.
Samples with high bit resolution (i.e. 24-bit samples) and high samplerate settings
(96kHz, 192kHz) make the collection size even bigger. In the case of
a non-monolithic format, the limitation still applies, but it applies to each sample
instead of to the sum of all samples, making the limit virtually unreachable.
While this limitation doesn't apply to NTFS, NTFS partitions are less efficient than
FAT32 disks in terms of raw disk performance for streaming applications.
Additionally, editing a single sample in a monolithic file implies loading the whole
file, and after edit, saving the whole file again to disk. When collection
size is big, the loading and saving operation is very time-consuming.
However, we have not discharged the possibility of incorporating a monolithic format
for the sfz format, as soon as the format structure is completely implemented.
Small sound sets (or NTFS users) could chose between the two options appropriately.
Why not XML?
XML was actually the first choice for the .sfz definition file, mainly due the simplicity
from the development point of view as the XML parser and transaction
code is already available.
However, XML was designed to exchange data over the web. Musicians, players, composers,
soundware developers and audio technicians generally do not know
about XML at all.
In addition, as a universal information exchange format designed for general-purpose
applications, XML is inefficient (in terms of information over total
data terms), and editing a XML file requires the use of a XML editor instead of a
text editor.
A .sfz file is extremely self-explanatory. Most of the functionality of an instrument
can be easily discovered by reading the file.
Is there a .sfz dedicated editor?
From rgc:audio, not yet... and not anytime soon.
However, we're working with several developers in the industry, creators of sample-conversion
software to implement the .sfz format in their converters
and editors.
The nature of the format allows creating instruments using other general-purpose
software, like spreadsheets, wordprocessors, simple-scripting languages
and other custom tailored software applications.
Implementation
How is an instrument defined?
The basic component of an instrument is a region. An instrument then, is defined
by one or more regions. Multiple regions can be arranged in a group. Groups
allow entering common parameters for multiple regions.
A region can include three main components: the definition for a sample, a set of
input controls and a set of performance parameters.
Sample
The sample opcode defines which sample file will be played when the region is defined
to play.
If a sample opcode is not present in the region, the region will play the sample
defined in the last <group>. If there's no previous group defined, or
if the previous group doesn't specify a sample opcode, the region will be ignored.
Input Controls
Input controls define when the sample defined in a region will play, based in real-world
controller values and/or internally calculated values.
Real-world controllers are the elements that players, musicians or composers actually
use to play music. Internal values are calculated by the player, like
sequence counters and random generators.
The sfz format relies in the standard Musical Instruments Digital Interface (MIDI)
specification for all input controls. Most available performance controllers
implement MIDI, and it's still the dominating specification for software audio sequencers
in all platforms.
Keyboard controllers are the most significant example of an Input Controls generator.
Other generators could be MIDI guitars and string instruments, wind
controllers, drum and percussion controllers. With individual differences, they all
generate a common set of messages defined in the MIDI specification.
A set of input controls then, are the combination of a played MIDI note with its
velocity, continuous controllers, pitch bend, channel and polyphonic aftertouch,
etc.
When a particular set of input controls matches the definition for a region, the
sample specified in that region plays, using a particular set of performance
parameters also specified in the region.
Inside the definition file, a region starts with the <region> header. A region is
defined between two <region> headers, or between a <region> header and
a <group> header, or between a <region> header and the end of the file.
Following the <region> header one or more opcodes can be defined. The opcodes are
special keywords which instruct the player on what, when and how to play
a sample.
Opcodes within a region can appear in any order, and they have to be separated by
one or more spaces or tabulation controls. Opcodes can appear in separated
lines within a region.
Opcodes and assigned opcode values are separated by the equal to sign (=), without
spaces between the opcode and the sign. For instance:
sample=trombone_a4_ff.wav
sample=cello_a5_pp first take.wav
are valid examples, while:
sample = cello_a4_pp.wav
Is not (note the spaces at the sides of the = sign).
Input Controls and Performance Parameters opcodes are optional, so they might not
be present in the definition file. An 'expectable' default value for
each parameter is pre-defined, and will be used if there's no definition.
Example region definitions:
<region> sample=440.wav
This region definition instructs the player to play the sample file '440.wav' for
the whole keyboard range.
<region> lokey=64 hikey=67 sample=440.wav
This region features a very basic set of input parameters (lokey and hikey, which
represent the low and high MIDI notes in the keyboard), and the sample
definition.
This instructs the player to play the sample '440.wav', if a key in the 64-67 range
is played.
It is very important to note that all Input Controls defined in a region act using
the AND boolean operator. Consequently, all conditions must be matched
for the region to play. For instance:
<region> lokey=64 hikey=67 lovel=0 hivel=34 locc1=0 hicc1=40 sample=440.wav
This region definition instructs the player to play the sample '440.wav' if there
is an incoming note event in the 64-67 range AND the note has a velocity
in the 0~34 range AND last modulation wheel (cc1) message was in the 0~40 range.
Performance parameters
The Performance Parameters define how the sample specified will play, once the region
is defined to play.
A simple example of a Performance Parameter is volume. It defines how loud the sample
will be played when the region plays.
Groups
As previously stated, groups allow entering common parameters for multiple regions.
A group is defined with the <group> opcode, and the parameters enumerated
on it last till the next group opcode, or till the end of the file.
<group>
ampeg_attack=0.04 ampeg_release=0.45
<region> sample=trumpet_pp_c4.wav key=c4
<region> sample=trumpet_pp_c#4.wav key=c#4
<region> sample=trumpet_pp_d4.wav key=d4
<region> sample=trumpet_pp_d#4.wav key=d#4
<group>
<region> sample=trumpet_pp_e4.wav key=e4 // previous group parameters reset
Comments
Comment lines can be inserted anywhere inside the file. A comment line starts with
the slash character ('/'), and it extends till the end of the line.
<region>
sample=trumpet_pp_c4.wav
// middle C in the keyboard
lokey=60
// pianissimo layer
lovel=0 hivel=20 // another comment
Where do the sample files have to be stored?
Sample files can be stored either in the same folder where the .sfz definition file
resides, or in any alternative route, specified relatively to the location
of the definition file. Consequently:
sample=trumpet_pp_c3.wav
sample=samples\trumpet_pp_c3.wav
sample=..\trumpet_pp_c3.wav
Are all valid sample names.
Alternatively, the player might specify one or several 'user folders', where it will
search for samples if it doesn't find them in the same folder as the
definition file.
What can the sfz format do?
The sfz format is aimed to allow the arrange of a sample collection in a flexible
and expandable way. It's up to the player to decide which functionality
it wants to implement.
Units
All units in the sfz format are in real-world values. Frequencies are expressed in
Hertz, pitches in cents, amplitudes in percentage and volumes in decibels.
Notes are expressed in MIDI Note Numbers, or in note names according to the International
Pitch Notation (IPN) convention. According to this rules, middle
C in the keyboard is C4 and the MIDI note number 60.
Opcode List
The following is a description of all valid opcodes for the sfz format version 1.0:

Sample Definition
sample
This opcode defines which sample file the region will play.
The value of this opcode is the filename of the sample file, including the extension.
The filename must be stored in the same folder where the definition
file is, or specified relatively to it.
If the sample file is not found, the player will ignore the whole region contents.
Long names and names with blank spaces and other special characters (excepting the
= character) are allowed in the sample definition.
The sample will play unchanged when a note equal to the pitch_keycenter opcode value
is played. If pitch_keycenter is not defined for the region, sample
will play unchanged on note 60 (middle C).

If a delay value is specified, the region playback will be postponed for the specified
time.
If the region receives a note-off message before delay time, the region won't play.
All envelope generators delay stage will start counting after region delay time.
Examples:
delay=1
delay=0.2

The player will reproduce the whole sample if end is not specified.
If end value is -1, the sample will not play. Marking a region end with -1 can be
used to use a silent region to turn off other regions by using the group
and off_by opcodes.
Examples:
end=133000
end=4432425
integer
0
-1 to 4 Gb (4294967296)
count
The number of times the sample will be played. If this opcode is specified, the sample

Examples:
count=3
count=2
integer
0
0 to 4 Gb (4294967296)
loop_mode
If loop_mode is not specified, each sample will play according to its predefined
loop mode. That is, the player will play the sample looped using the first
defined loop, if available. If no loops are defined, the wave will play unlooped.
The loop_mode opcode allows playing samples with loops defined in the unlooped mode.
The possible values are:
no_loop: no looping will be performed. Sample will play straight from start to end,
or until note off, whatever reaches first.
one_shot: sample will play from start to end, ignoring note off.
This mode is engaged automatically if the count opcode is defined.
loop_continuous: once the player reaches sample loop point, the loop will play until
note expiration.
loop_sustain: the player will play the loop while the note is held, by keeping it
depressed or by using the sustain pedal (CC64). The rest of the sample
will play after note release.
Examples:
loop_mode=no_loop
loop_mode=loop_continuous
text
no_loop for samples without a loop defined,
loop_continuous for samples with defined loop(s).

When sync_beats is specified and after input controls instruct the region to play,
the playback will be postponed until the next multiple of the specified
value is crossed.
Examples:

until beat 4 reaches.
This opcode will only work in hosts featuring song position information (vstTimeInfo
ppqPos).
floating point
0
0 to 32 beats
sync_offset
Region playing synchronization to host position offset.
When sync_beats is specified and after input controls instruct the region to play,

and compensating for the resulting volume change). A value of 100
will make the stereo sample play as original.
Any value in between will mix left and right channels with a part of the other, resulting
in a narrower stereo field image.
