spectral-subtraction

This is a single channel speech dereverberation method based on DOI: 10.1109/TSA.2005.858066; implemented in MATLAB

Hubbub Suppression for Voice

Various melodic noise filtering techniques viz. Adaptive Noise Cancellation, Spectral Methods and Deep Learning algorithms have been employed to filter music signals corrupted with additive Gaussian white noise. The noise reduction problem has been formulated as a filtering problem which is efficiently solved by using the LMS, NLMS and RLS metho…

Filtering unwanted background noise from .wav files using different algorithms (Moving Average, Frequency Domain Filter and Spectral Subtraction)

Streaming Berouti-style modified spectral subtraction for real-time audio noise reduction. Pure DSP, no model weights, no GPU.

B.tech Major project

On-device voice cleanup for talking-head video/audio — spectral-gate noise reduction + EQ/de-ess/compression/normalization, pure DSP on Accelerate, zero dependencies. Pluggable NoiseReducer seam for an opt-in ML (DeepFilterNet) mode.

Power Spectral Subtraction implemented in Python for removal of additive background noise.

Noise-robust keyword spotting on Google Speech Commands + MUSAN corpus. CNN vs AST, three preprocessing strategies, five SNRs.

Project used to denoise noisy audio files. This project uses spectral substraction method.

MATLAB FFT applications: spectral-subtraction noise removal, harmonic product spectrum pitch detection, and frequency-domain image filtering

Project for the Signal Processing course @acs, UPB 2021

纯 Python 语音降噪入门工具包：谱减法/维纳滤波/log-MMSE 等经典单通道降噪 + SNR/PESQ 风格评估与可视化

MATLAB implementation of audio noise reduction using Fast Fourier Transform (FFT) and Spectral Subtraction, based on research by Karam et al. (2014).

Do classical signal-processing front-ends help a modern neural speaker diarizer? DT2119 project at KTH, graded A. Spectral Subtraction and NMF+VAD are placed before an unmodified pyannote 3.1 baseline on a synthetic overlap and noise dataset. Both fail: the artefacts they add cost more than the corruption they remove.
