The version numbers merely reflect which versions I have been using during development.

Example

import sys
import pyxaudio

# Open the playback sink.
sink = pyxaudio.Sink()

for url in sys.argv[1:]:
    if sys.version_info.major == 2:
        # pyxaudio needs all strings as unicode objects.
        url = url.decode(sys.getfilesystemencoding())

    # Create a new decoding source for the url.
    source = pyxaudio.Source(url)

    # Configure the sink.
    sink.setup(source)

    while True:
        buf = source.read(8192)
        if not buf:
            break
        sink.write(buf)

    # Clean up.
    source.close()
sink.close()
