GPU DeClicker
This program removes clicks, pops and bitrots from audio files
There is a one common problem in capturing audio from old vinyl disks. Many of the disks have scratches that impose needles to make little jumps producing short sharp noises named 'click'. My project's aim was to create a free software which able to remove this kind of noise from audio files produced by capturing vinyl disk. Also the application is able to remove some other kinds of short sharp noises like 'bitrots'. The program can detect start positions and lengths of clicks and... -

WaveShop
Fast, bit-perfect audio editor that doesn't modify samples needlessly
WaveShop is an audio editor for Windows XP/Vista/7/8. Unlike many similar apps, WaveShop is bit-perfect, meaning samples aren't altered unless they need to be.

This is especially useful for patching a finished master without corrupting its dither. -

SpecAnaSyn
Spectral Analysis and Synthesis of Sounds
This project provides two binaries, mostly identical in features: a command line application (using libpopt for option parsing), and a graphical application (using libgtkmm (version 2) for the GUI and libao for sound playing). It uses spectral modelling techniques for parameterized sound analysis and synthesis. For the analysis phase an STFT is done (using libfftw for doing FFTs), and then harmonic/sinusoidal analysis. For the synthesis phase additive synthesis is used. Using libsndfile for... -
