Musical instrument strobe tuner: a real-time emulation

Various reference programs to read baseband I/Q sample data from a Funcube Dongle Pro+ (FCDPP) software defined radio (SDR) hardware front end, demodulate the data stream and send it to the host's audio output port. Programs are present to demodulate AM, CW, FM and SSB (USB, LSB) streams. Also included is a program that writes FCDPP sample data to its standard output (stdout) port. The programs require the qthid program to control the FCDPP frequency and gain (also available at...

A cross platform dual channel FFT based Acoustic Analysis Tool to help engineers analyze live professional sound systems using the transfer function. One feature is the ability to capture four sample plots, average them, and invert to aid in final EQ

Zwicker's Loudness Calculation (ISO532B) Tools. The project includes a loudness calculation program based on Zwicker's Method, and a WAV file analyzer generating data files for loudness calculation. Documentation and test files are also provided.

This software generates a distorted version of an audio file that can give a required audio quality. This is for use with subjective tests, such as MUSHRA, where an anchor is required of a particular quality.
