PyAudio

The following only summarizes information from the PyAudio Web page.

PyAudio provides Python bindings for the PortAudio audio I/O library. The current version of PyAudio is V0.1.0, which is alpha quality.

Multi-platform
    Package is compilable for MS-Windows, Apple Mac OS X, Linux and cygwin.
Real-time sound acquisition
    Unknown
Support for 16KHz sampling rate and >8-bit sound
    Unknown.
Sound file processing
    Unknown.
Efficiency
    Unknown.
Pitch existence and frequency
    Unknown.
Formants and their bandwidths
    Unknown.
FFT with pre-emphasis and Hamming window
    Unknown.
Power
    Unknown.

PyMedia.py

The documentation is very sketchy.

Multi-platform
    Package is compilable for MS-Windows, Linux and cygwin.
Real-time sound acquisition
    Unknown
Support for 16KHz sampling rate and >8-bit sound
    Probably depends upon sound card.
Sound file processing
    Yes.
Efficiency
    Unknown.
Pitch existence and frequency
    Use another package for this.
Formants and their bandwidths
    Use another package for this.
FFT with pre-emphasis and Hamming window
    Use another package for this.
Power
    Use another package for this.

MCI.py (from Arik Baratz) together with ctypes.py

Multi-platform
    ctypes.py is supported by all 32-bit MS Windows (95/98/NT/2000/XP), All BSD Platforms (FreeBSD/NetBSD/OpenBSD/Apple Mac OS X), All POSIX (Linux/BSD/UNIX-like OSes), WinCE.
    MCI.py was designed to communicate with MS-Windows winmm.dll.
Real-time sound acquisition
    Unknown.
Support for 16KHz sampling rate and >8-bit sound
    Unknown.
Sound file processing
    Seems to be able to record to a file.
Efficiency
    Commands are sent as strings.
Pitch existence and frequency
    Use another package for this.
Formants and their bandwidths
    Use another package for this.
FFT with pre-emphasis and Hamming window
    Use another package for this.
Power
    Use another package for this.

ossaudiodev

Multi-platform
    Not enough. Implemented in Linux and FreeBSD. Available for a wide range of open-source and commercial Unices. But apparently not for MS-Windows.
Real-time sound acquisition
    Blocking reads, by default. Probably can set to non-blocking.
Support for 16KHz sampling rate and >8-bit sound
    Seems to depend upon the sound card.
Sound file processing
    Use another package for this.
Efficiency
    Direct I/O access.
Pitch existence and frequency
    Use another package for this.
Formants and their bandwidths
    Use another package for this.
FFT with pre-emphasis and Hamming window
    Use another package for this.
Power
    Use another package for this.

Snack

Multi-platform
    The same scripts are usable on Windows 95/98/NT/2K/XP, Linux, Macintosh, Sun Solaris, HP-UX, FreeBSD, NetBSD, and SGI IRIX.
Real-time sound acquisition
    Yes.
Support for 16KHz sampling rate and >8-bit sound
    Yes.
Sound file processing
    Yes.
Efficiency
    Inefficient - data is converted into string by the Tcl part of the package and then converted back into data by the Python part.
Pitch existence and frequency
    Yes. Each 10mSec, using the ESPS method (the ADMF method is available, too).
Formants and their bandwidths
    http://www.speech.kth.se/snack/man/snack2.2/tcl-man.html#sound - see the formant subcommand.
FFT with pre-emphasis and Hamming window
    See above link - the powerSpectrum subcommand.
Power
    See above link - the power subcommand.
