audioairwindows brings Chris Johnson's Airwindows plug-ins, 528 of them, to audiodsp's audio graph on CPython and MicroPython-compatible firmware.

Install

On CPython 3.11 or later:

pip install omnipython-airwindows

That installs a prebuilt wheel, and omnipython-audiodsp 0.6.10 or later beside it. Install lists the platforms that have a wheel and how to build from source on the rest.

On MicroPython, build this repository into the firmware next to audiodsp 0.6.10 or later: Install has the command.

Try it

from array import array
import audiocore, audioairwindows

RATE = 48000
noise, x = array("h"), 1
for _ in range(RATE // 50):
    x = (x * 1103515245 + 12345) & 0x7fffffff
    noise.append((x >> 16) % 20001 - 10000)

verb = audioairwindows.Galactic(sample_rate=RATE, channel_count=1, replace=0.3)
verb.play(audiocore.RawSample(noise, sample_rate=RATE, channel_count=1))
for row in range(12):
    loudest = 0
    for _ in range(48):
        block = array("h", bytes(audiocore.get_buffer(verb)[1]))
        loudest = max(loudest, max(abs(v) for v in block))
    print("%.2f s  %5d" % (row * 48 * 256 / RATE, loudest))

It prints the loudest sample of each quarter second or so, the same on CPython and MicroPython:

0.00 s    247
0.26 s    343
0.51 s    307
0.77 s    243
1.02 s    325
1.28 s    203
1.54 s    194
1.79 s    194
2.05 s    155
2.30 s    144
2.56 s     86
2.82 s     92
