SDL_sound is a library that handles the decoding of several popular
sound file formats, such as raw, wav, mp3, flac, ogg, voc, shn,
aiff, au, and some others.
It is meant to make the programmer's sound playback tasks simpler.
The programmer gives SDL_sound a filename, or feeds it data directly
from one of many sources, and then reads the decoded waveform data
back at her leisure.
If resource constraints are a concern, SDL_sound can process sound
data in programmer-specified blocks. Alternately, SDL_sound can
decode a whole sound file and hand back a single pointer to the
whole waveform.
SDL_sound can also handle sample rate, audio format, and channel
conversion on-the-fly and behind-the-scenes, if the programmer
desires.
shntool is a multi-purpose WAVE data processing and reporting utility.
File formats are abstracted from its core, so it can process any file
that contains WAVE data, compressed or not -- provided there exists a
format module to handle that particular file type.
Apart from .wav shntool supports many formats through helper programs.
Please see the manual page for more information.
The Snack Sound Toolkit is designed to be used with a scripting language
such as Tcl/Tk or Python. Using Snack you can create powerful multi-platform
audio applications with just a few lines of code. Snack has commands for
basic sound handling, e.g. sound card and disk I/O. Snack also has primitives
for sound visualization, e.g. waveforms and spectrograms. It was developed
mainly to handle digital recordings of speech, but is just as useful for
general audio. Snack has also successfully been applied to other one-
dimensional signals.
The combination of Snack and a scripting language makes it possible to create
sound tools and applications with a minimum of effort. This is due to the
rapid development nature of scripting languages. As a bonus you get an
application that is cross-platform from start. It is also easy to integrate
Snack based applications with existing sound analysis software.
Snd is a sound editor modeled loosely after Emacs and an old, sorely-missed
PDP-10 sound editor named Dpysnd. It can accommodate any number of sounds,
each with any number of channels, and can be customized and extended using
Guile, Ruby or Forth.
Included with it are some command-line utilities:
- snd-info (note: renamed from sndinfo, for this FreeBSD port) prints a
description of a sound file.
- sndplay plays a sound file.
- sndrecord records sound from a microphone.
- audinfo describes the current state of the audio hardware.

Sphinx 3 is a frontend to the sphinxbase, a large-vocabulary,
speaker-independent, continuous speech recognition engine.
Once the system is built, try running the Perl script sphinx3-demo.
The sphinx3-test script should run sphinx3-batch over an example
utterance of "go forward ten meters."
Sphinx Base is part of a large-vocabulary, speaker-independent, continuous
speech recognition engine.
This port is required for PocketSphinx and Sphinx3
Once the system is built, try running the Perl script sphinx-demo.
The sphinx-test script should run sphinx-batch over an example
utterance of "go forward ten meters."
SpiralLoops is an experimental loop-based sampler for Linux and FreeBSD.
The idea of SpiralLoops is to provide a simple, visual tool for looping
and layering of sounds; which can be sourced from either WAV files on disk,
or from sound-generating plugins.
SpiralLoops allows you to create loop-based compositions with the minimum
feedback time between the decisions you make and your ears. The looping
mechanism is very flexible; you can lock the timing of loops together, or
offset them for creating complex sequences, such as polyrhythms.
Loop triggers can be used to cause interaction between the loops, and as
an experimental way of creating music.
adapted from the Web page and the README:
Spiral Synth is a physically modelled, monophonic, analogue
synthesizer. It is capable of creating the kind of sounds made by
hardware analogue synths, the noises used in electronic music.
You can also use it to make stranger sounds. MIDI is supported,
including velocity detection, mapped to the volume of the oscillators
(but you can also use the PC keyboard to play the synth). Output
is to /dev/dsp or in Microsoft RIFF (.WAV) format to a file. You
can save and recall your sounds using the 100 patch save slots.
The PC keyboard can be used to play the synth, "q" & "z" are C,
and the keys progress from them: "2" is C#, "w" is D, etc. These
are just the defaults, and can be changed from the .Spiralrc file.
The function keys change the octave.
Sample output and a detailed list of features can be found on the
home page.
