Audio signal analysis and processing

Alexey Lukin, Maxim Tkachenko
Audio signals can be converted to a 2D representation — spectrogram — by a Short-Time Fourier Transform (STFT).
Many image processing methods can be applied to spectrograms for the purposes of noise reduction, instrument extraction, identification. Multiresolution methods can improve precision of spectrogram analysis and reduce artifacts of a typical STFT processing, like ringing or energy smearing.
We have the following projects in audio processing:
