PortAudio.Buffer — Type
struct PortAudio.Buffer{Sample}A PortAudio.Buffer contains everything you might need to read or write data from or to PortAudio. The data field contains the raw data in the buffer. Use PortAudio.write_buffer to write data to PortAudio, and PortAudio.read_buffer! to read data from PortAudio.
#
PortAudio.Messenger — Type
Messenger{Sample, Scribe, Input, Output}A struct with entries
-
device_name::String -
buffer::Buffer{Sample} -
scribe::Scribe -
input_channel::Channel{Input} -
output_channel::Channel{Output}
The messenger will send tasks to the scribe; the scribe will read/write from the buffer.
#
PortAudio.SampledSignalsReader — Type
struct PortAudio.SampledSignalsReaderA PortAudio.Scribe that will use the SampledSignals package to manage reading data from PortAudio.
#
PortAudio.SampledSignalsWriter — Type
struct PortAudio.SampledSignalsReaderA PortAudio.Scribe that will use the SampledSignals package to manage writing data to PortAudio.
#
PortAudio.Scribe — Type
abstract type PortAudio.Scribe endA scribe must implement the following:
-
A method for
PortAudio.get_input_type -
A method for
PortAudio.get_output_type -
A method to call itself on two arguments: a
PortAudio.Bufferand an input of the input type. This method must return an output of the output type. This method should make use ofPortAudio.read_buffer!andPortAudio.write_buffer.
#
PortAudio.get_input_type — Method
PortAudio.get_input_type(scribe::PortAudio.Scribe, Sample)Get the input type of a PortAudio.Scribe for samples of type Sample.
#
PortAudio.get_output_type — Method
PortAudio.get_input_type(scribe::PortAudio.Scribe, Sample)Get the output type of a PortAudio.Scribe for samples of type Sample.
#
PortAudio.read_buffer! — Function
PortAudio.read_buffer!(buffer::Buffer, use_frames = buffer.frames_per_buffer; acquire_lock = true)Read a number of frames (use_frames) from PortAudio to a PortAudio.Buffer.
Set acquire_lock = false to skip acquiring the acquire_lock.
#
PortAudio.write_buffer — Function
PortAudio.write_buffer(buffer, use_frames = buffer.frames_per_buffer; acquire_lock = true)Write a number of frames (use_frames) from a PortAudio.Buffer to PortAudio.
Set acquire_lock = false to skip acquiring the lock.
