Compiling

Compiling Speex under UNIX/Linux or any other platform supported by autoconf (e.g. Win32/cygwin) is as easy as typing:

% ./configure [options]

% make

% make install

The options supported by the Speex configure script are:

-prefix=<path>

Specifies the base path for installing Speex (e.g. /usr)

-enable-shared/-disable-shared

Whether to compile shared libraries

-enable-static/-disable-static

Whether to compile static libraries

-disable-wideband

Disable the wideband part of Speex (typically to save space)

-enable-valgrind

Enable extra hits for valgrind for debugging purposes (do not use by default)

-enable-sse

Enable use of SSE instructions (x86/float only)

-enable-fixed-point

Compile Speex for a processor that does not have a floating point unit (FPU)

-enable-arm4-asm

Enable assembly specific to the ARMv4 architecture (gcc only)

-enable-arm5e-asm

Enable assembly specific to the ARMv5E architecture (gcc only)

-enable-fixed-point-debug

Use only for debugging the fixed-point code (very slow)

-enable-epic-48k

Enable a special (and non-compatible) 4.8 kbps narrowband mode

-enable-ti-c55x

Enable support for the TI C5x family

-enable-blackfin-asm

Enable assembly specific to the Blackfin DSP architecture (gcc only)

-enable-vorbis-psycho

Make the encoder use the Vorbis psycho-acoustic model. This is very experimental and may be removed in the future.

Platforms

Speex is known to compile and work on a large number of architectures, both floating-point and fixed-point. In general, any architecture that can natively compute the multiplication of two signed 16-bit numbers (32-bit result) and runs at a sufficient clock rate (architecture-dependent) is capable of running Speex. Architectures that are known to be supported (it probably works on many others) are:

• x86 & x86-64
• Power
• SPARC
• ARM
• Blackfin
• TI C54xx & C55xx
• TI C6xxx
• TriMedia (experimental)

Operating systems on top of which Speex is known to work include (it probably works on many others):

• Linux
• $\mu$ Clinux
• MacOS X
• BSD
• Other UNIX/POSIX variants
• Symbian

The source code directory include additional information for compiling on certain architectures or operating systems in README.xxx files.
