cyfaust

A minimal, modular, self-contained, cross-platform Cython wrapper of the Faust DSP language and the RtAudio cross-platform audio driver.

Features

• Dual Backends: Interpreter (default, ~8MB) or LLVM JIT (~71MB, faster execution)
• Box API: Fully wrapped with both functional and object-oriented interfaces
• Signal API: Fully wrapped with both functional and object-oriented interfaces
• Platform Support: macOS, Linux, and Windows
• Build Variants: Dynamic (libfaust.so|dylib) and static (libfaust.a|lib)
• Faust Version: 2.83.1

Quick Example

from cyfaust.interp import create_dsp_factory_from_string, RtAudioDriver
import time

# Create a DSP factory from Faust code
factory = create_dsp_factory_from_string("test",
    "import(\"stdfaust.lib\"); process = os.osc(440);")

# Create a DSP instance and initialize it
dsp = factory.create_dsp_instance()
dsp.init(48000)

# Play audio through RtAudio
driver = RtAudioDriver(48000, 256)
driver.init(dsp)
driver.start()
time.sleep(2)
driver.stop()
