*here* (special variable).
Definitions are sorted by export status, category, package, and then by lexicographic order.
This variable holds the default sample rate used throughout.
This is set to 44100 for 44.1 kHz, which is
the standard sample rate for CD audio and should
thus be of sufficient quality for most purposes.
Variable containing the path to the static directory. That directory contains the precompiled library binaries.
Convenience macro to handle a transfer from one buffer to another.
Both FROM and TO may be the same buffer, in which case the transfer
happens from the region available to read to itself.
Otherwise, this is akin to nesting WITH-BUFFER-TX, with the special
exemption that FINISH will complete the transaction on both buffers at
once.
See BIP-BUFFER
See BUFFER
See PACK
See WITH-BUFFER-TRANSFER
Convenience macro to handle a buffer transaction.
DATA is bound to the storage array of the buffer.
START is bound to the starting index of the transaction.
SIZE is bound to the number of elements that may be operated on during
the transaction.
BUFFER should be a BIP-BUFFER instance.
DIRECTION can be either :INPUT or :OUTPUT depending on the type of
transaction desired.
INITIAL-SIZE should be the amount of space to request.
During BODY, two functions are available:
FINISH — Completes the transaction, using the passed number of
elements. Note that this does not cause an unwind.
DATA-PTR — Returns a foreign pointer to the start of the
transaction’s valid memory.
This macro ensures that on unwind for any reason, whether after FINISH
or before, the buffer is left in a sealed state where it is safe to
call REQUEST-READ and REQUEST-WRITE again.

See BUFFER
See PACK
See WITH-BUFFER-TRANSFER
Create a number of buffers for the duration of the body.
BUFFERS should be a list of symbols, to each of which a fresh instance of a BUFFER with a size of SAMPLES will be bound.

Superclass for all objects that track foreign resources.
If no handle is given to the object upon creation, the proper
corresponding foreign data is automatically allocated. The
pointer to this data is then associated with the instance to
allow resolving the pointer to the original Lisp object.
Finalisation of the foreign data upon garbage collection of
the Lisp object is also handled.
The actual foreign allocation and cleanup of the data is
handled by ALLOCATE-HANDLE and FREE-HANDLE respectively. The
subclass in question is responsible for implementing
appropriate methods for them.

A pack represents an interface to an outside sound source or drain.
The object holds all the necessary information to describe
the audio data present in a raw byte buffer. This includes
how many channels there are, how the samples are laid out
and how the samples are formatted in memory. It also includes
the samplerate of the channel’s source so that it can be
converted if necessary.
Note that a pack only supports interleaved channel data. If the data
is sequential in memory, it must be handled by multiple packs.

This segment converts data from individual sample buffers to data for packed-audio.
This is mostly useful at the edges to convert to
something like an audio file library or audio
playback system from the internal buffers as used
by Mixed.
The samplerate argument defines the sample rate
in the input buffers. If it diverges from the
sample rate in the packed-audio, resampling occurs to
account for this.

This segment repeats a recorded bit of its input sequence.
The segment is first in record mode when created.
Once you have the bit you want to repeat back, you
can switch the repeat-mode to :PLAY. It will then
ignore the input and instead continuously output the
recorded input bit.

Superclass for all mixing pipeline segments.
A segment is responsible for producing, consuming,
combining, splitting, or just in general somehow
processing audio data within a pipeline.
A segment is connected to several buffers at its inputs and outputs. Each input, output, and the segment itself may have a number of fields that can be accessed to change the properties of the segment’s behaviour.
Some of these properties may not be changed in real
time and instead might require a ending the mixing
first.

A segment to simulate audio effects in 3D space.
Each input represents an individual source in space.
Each such source can have a location and a velocity,
both of which are vectors of three elements. If the
velocity is non-zero, a doppler effect is applied to
the source.
The segment itself also has a :LOCATION and :VELOCITY, representing the listener’s own properties. It has some additional fields to change the properties of the 3D space. In total, the following fields are available:
:LOCATION — The location of the input or
listener. Value should be a list
of three floats.
:VELOCITY — The velocity of the input or
listener. Value should be a list
of three floats.
:DIRECTION — The direction the listener is
facing. Value should be a list of
three floats. Default is (0 0 1)
:UP — The vector pointing "up" in
space. Value should be a list of
three floats. Default is (0 1 0)
:SOUNDSPEED — The speed of sound in the medium.
Default is 34330, meaning "1" is
measured as 1cm.
:DOPPLER-FACTOR — This can be used to over- or
understate the effect of the
doppler. Default is 1.0.
:MIN-DISTANCE — The minimal distance under which
the source has reached max volume.
:MAX-DISTANCE — The maximal distance over which
the source is completely inaudible.
:ROLLOFF — The rolloff factor describing the
curvature of the attenuation
function.
:ATTENUATION — The attenuation function describing
how volume changes over distance.
Should be one of :NONE :LINEAR
:INVERSE :EXPONENTIAL.

This segment converts data from packed-audio to individual sample buffers.
This is mostly useful at the edges to convert from
something like an audio file library to the format
needed by Mixed.
The samplerate argument defines the sample rate
in the output buffers. If it diverges from the
sample rate in the packed-audio, resampling occurs to
account for this.

Superclass for segments implemented in Lisp.
The segment should implement the following
methods according to its need:
INFO
START
MIX
END
INPUT-FIELD
(SETF INPUT-FIELD)
OUTPUT-FIELD
(SETF OUTPUT-FIELD)
FIELD
Default methods for INPUT/OUTPUT-FIELD to
handle the recording of the input/output
buffers already exist. Every other method
by default does nothing. You should in the
very least implement a method for MIX on
your subclass.

A volume control segment that can change the volume and pan.
This is a stereo segment, and as such requires two
input and output buffers each. You may use the
location keywords :LEFT and :RIGHT to address them.
The pan goes from -1.0 for left to 1.0 for right.
The volume goes from 0.0 upwards. Values below zero
result in an error, and values above 1.0 will likely
lead to clipping and thus audio distortions.

A weak value table associating pointer addresses to corresponding objects.
This table keeps track of which foreign data is tracked
by which lisp instance.
See POINTER->OBJECT
See C-OBJECT
Variable containing the path to the low-level.lisp file.
Define a new accessor wrapper for a CFFI struct function.
Defines a new callback that handles errors automatically.
If an error occurs within BODY, the ERROR-RETURN form
is instead evaluated and its value returned.
See CFFI:DEFCALLBACK
Define an accessor that delegates its call to a slot of the instance.
Generates the necessary accessor methods to wrap
the access.
Define an accessor for a segment’s field.
Generates the necessary methods on FIELD as well as convenience wrapper methods.
Define an accessor for a segment’s input vector value field.
Generates the necessary methods on FIELD as well as
convenience wrapper methods. The values should be
lists or vectors of three floats.
Define a standard callback function.
Standard means that the function will return 1 on
success and 0 on abnormal exit.
See DEFINE-CALLBACK
Define an accessor for a segment’s vector value field.
Generates the necessary methods on FIELD as well as convenience wrapper methods. The values should be lists or vectors of three floats.
If the body unwinds abnormally, CLEANUP is run.
Shorthand to handle return values of C functions.
If the last form in the body returns a zero, an
error of type MIXED-ERROR is signalled.
See MIXED-ERROR
Allocate a region of foreign data on the heap.
This is like CFFI:FOREIGN-ALLOC, except that the memory region is zeroed out before the pointer to it is returned.
Coerce the given value to the type and range appropriate for the given C-type.
Coercion is done for:
:FLOAT
:DOUBLE
:INT
:UINT
Decode the field info contained in the pointer to a segment-info struct.

Convert a pointer to a C array of three floats to a vector.
Remove the given key/value pairs from the plist.
Returns a fresh list.
Convert the vector into a C array of three floats
Set the value at the given position in the vector.
If the position is beyond the vector’s length, it is first adjusted to that length.
