compile(code; name="score", argv=[], target="", opt=-1)

Compiles code to a DSPBlock.

Arguments

• argv::Vector{String}: List of args to the Faust compiler, e.g. "-double": double precision "-vec": vectorize code.
• target::String: target for which to build LLVM IR. Defaults to current machine.
• opt::Integer: -1 is "highest level available".

Examples

julia> d = compile("import("stdfaust.lib"); process = os.osc(freq) : *(0.25) <: _, _;")

compute!(d)

Computes d.block_size samples of signal and returns d.outputs (d.blocksize, noutputs).

d.inputs should be assigned an incoming signals matrix of dims (d.blocksize, ninputs) before calling this function.

Examples

julia> d = init!(compile("import("stdfaust.lib"); process = os.oscs(440);"));
julia> compute!(d)

init!(d; block_size=256, samplerate=44100)

Initializes the DSPBlock d for use.

Must be called before compute!. The old DSP instance will be deleted, so this can be called repeatedly and will reset internal states, etc.

setparams!(d, params)

Sets the parameters on d using keys from params.

One can extract the available params as UIRange structs from d.ui.ranges after iniialization.

Examples

julia> d = init!(compile("process = nentry("v", 0, 0, 1, 0.001);"))
julia> d.ui.ranges
Dict{String, Faust.UIRange} with 1 entry:
  "/score/v" => UIRange(0.0, 0.0, 1.0, 0.001)
julia> setparams!(d, Dict("/score/v" => 0.5f0))
