PortAudio.jl

|
||||
|
||||
PortAudio.jl is a wrapper for [libportaudio](http://www.portaudio.com/), which gives cross-platform access to audio devices. It is compatible with the types defined in [SampledSignals.jl](https://github.com/JuliaAudio/SampledSignals.jl). It provides a `PortAudioStream` type, which can be read from and written to.
|
||||
|
||||
## Opening a stream
|
||||
|
||||
The easiest way to open a source or sink is with the default `PortAudioStream()` constructor, which will open a 2-in, 2-out stream to your system's default device(s). The constructor can also take the input and output channel counts as positional arguments, or a variety of other keyword arguments.
|
||||
|
||||
```julia
|
||||
PortAudioStream(inchans=2, outchans=2; eltype=Float32, samplerate=48000Hz, latency=0.1, synced=false)
|
||||
```
|
||||
|
||||
You can open a specific device by adding it as the first argument, either as a `PortAudioDevice` instance or by name. You can also give separate names or devices if you want different input and output devices
|
||||
|
||||
```julia
|
||||
PortAudioStream(device::PortAudioDevice, args...; kwargs...)
|
||||
PortAudioStream(devname::AbstractString, args...; kwargs...)
|
||||
```
|
||||
|
||||
You can get a list of your system's devices with the `PortAudio.devices()` function:
|
||||
|
||||
```julia
|
||||
julia> PortAudio.devices()
|
||||
6-element Array{PortAudio.PortAudioDevice,1}:
|
||||
PortAudio.PortAudioDevice("AirPlay","Core Audio",0,2,0)
|
||||
PortAudio.PortAudioDevice("Built-in Microph","Core Audio",2,0,1)
|
||||
PortAudio.PortAudioDevice("Built-in Output","Core Audio",0,2,2)
|
||||
PortAudio.PortAudioDevice("JackRouter","Core Audio",2,2,3)
|
||||
PortAudio.PortAudioDevice("After Effects 13.5","Core Audio",0,0,4)
|
||||
PortAudio.PortAudioDevice("Built-In Aggregate","Core Audio",2,2,5)
|
||||
```
|
||||
|
||||
### Input/Output Synchronization
|
||||
|
||||
The `synced` keyword argument to `PortAudioStream` controls whether the input and output ringbuffers are kept synchronized or not, which only effects duplex streams. It should be set to `true` if you need consistent input-to-output latency. In a synchronized stream, the underlying PortAudio callback will only read and write to the buffers an equal number of frames. In a synchronized stream, the user must also read and write an equal number of frames to the stream. If it is only written to or read from, it will eventually block. This is why it is `false` by default.
|
||||
|
||||
|
||||
## Reading and Writing
|
||||
|
||||
The `PortAudioStream` type has `source` and `sink` fields which are of type `PortAudioSource <: SampleSource` and `PortAudioSink <: SampleSink`, respectively. are subtypes of `SampleSource` and `SampleSink`, respectively (from [SampledSignals.jl](https://github.com/JuliaAudio/SampledSignals.jl)). This means they support all the stream and buffer features defined there. For example, if you load SampledSignals with `using SampledSignals` you can read 5 seconds to a buffer with `buf = read(stream.source, 5s)`, regardless of the sample rate of the device.
|
||||
|
||||
PortAudio.jl also provides convenience wrappers around the `PortAudioStream` type so you can read and write to it directly, e.g. `write(stream, stream)` will set up a loopback that will read from the input and play it back on the output.
|
||||
PortAudio.jl is a wrapper for [libportaudio](http://www.portaudio.com/), which gives cross-platform access to audio devices.
|
||||
It provides a `PortAudioStream` type, which can be read from and written to.

## Examples
|
||||
|
||||
### Set up an audio pass-through from microphone to speaker
|
||||
|
||||
```julia
|
||||
stream = PortAudioStream(2, 2)
|
||||
try
|
||||
# cancel with Ctrl-C
|
||||
write(stream, stream)
|
||||
finally
|
||||
close(stream)
|
||||
end
|
||||
```
|
||||
|
||||
### Use `do` syntax to auto-close the stream
|
||||
```julia
|
||||
PortAudioStream(2, 2) do stream
|
||||
write(stream, stream)
|
||||
end
|
||||
```
|
||||
|
||||
### Open your built-in microphone and speaker by name
|
||||
```julia
|
||||
PortAudioStream("Built-in Microph", "Built-in Output") do stream
|
||||
write(stream, stream)
|
||||
end
|
||||
```
|
||||
|
||||
### Record 10 seconds of audio and save to an ogg file
|
||||
|
||||
```julia
|
||||
julia> using PortAudio, SampledSignals, LibSndFile
|
||||
|
||||
julia> stream = PortAudioStream("Built-in Microph", 2, 0)
|

The clang generators will automatically generate wrappers for a C library based on its headers. So everything you see in libportaudio.jl is automatically generated from the C library. If a newer version of portaudio adds more features, we won't have to add new wrappers: clang will handle it for us. It is easy to use currently unused features: the wrappers have already been written for us. Even though it does an admirable job, clang doesn't handle errors and set locks. Fortunately, it's very easy to add secondary wrappers, or just do it at point of use.
