IP-Sound  ^pop - IP-Sound is a Free application for audio exchange client to client over a TCP/IPv4 network (Lan/Internet). The main purpose for the existence of IP-Sound is to provide low quality audio 8-16kHz, with low latency for use together with remote control software for "ham" radio amateur equipment. IP-Sound is developed by SM5VXC.

FreqTweak - FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display for Linux. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.

FFT Explorer - A free (GPL) Linux (Xwindows GUI-based) utility that performs spectral analysis on real-time data from a sound card or other source, and can analyze the spectra of various sound file types. It can also accept data from many kinds of applications in plain-text form by way of the "named pipe" feature of Linux
