xoscope is a digital oscilloscope using input from a sound card or
EsounD and/or a ProbeScope/osziFOX and will soon support Bitscope
hardware. Includes 8 signal displays, variable time scale, math,
memory, measurements, and file save/load.
Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually.
Quickplot is a fast interactive 2D plotter with infinite zooming, value picking, pipe input, and unlimited plots displayed. Quickplot is meant for looking at your data quickly and of secondary importance is making static pictures of your data.
Python Script to process a wave file and transform to movement (key frames) on Blender 2.5. Input: sound file (.wav) Output: Key frames direct into the selected object Work to meshes and bones (location, scale or rotation in any axis)

Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually. It has been renamed "pdatascope" to avoid a name-clash with Pyscope, a scoping package on PyPi. See https://sourceforge.net/p/pydatascope/ for the latest code.
Online Guitar Tuner java applet which analyse your microphone or any other sound input to find fundamental frequency using a Fast Fourier Transform.
Classical "Vintage" design looking like real guitar tuners.
A set of Qt/C++ classes enabling cross-platform sound recording and pitch recognition. Can be used in software (e.g. instrument tuners, sound dictation, music teaching and tests) as a user input method. Includes a guitar-tuner example.
Beat tracking software that produces a real time beat-pattern hierarchy with real time latency requirements. The system utilizes a blackboard structure over amplitude to construct the beat hierarcy from a standard JMF input stream.
eXtace is a 3D audio visualization tool (or eye candy depending on how you look at it). eXtace requires ESD (Esound) for its sound input source. It performs a FFT (fast fourier transform) on audio and displays it via various graphical modes.
HASAS (HydroAcoustic Signal Analysis System) is a modular system for passive sonar signal analysis. It can be used for biological research or surveillance, for example. The soundcard is used as input device, and it currently includes all the very basic fu
