Vocal Cleaning: How AI Noise Reduction Works

Having a good microphone isn't always enough. PulsConv's Audio Clear tool uses Fast Fourier Transform (FFT) filters to clean your recordings. **Spectral Subtraction**: The algorithm analyzes constant frequencies (a fan's hum or wind) and subtracts them from the overall audio signal. **Gate & Compression**: After cleaning, we apply a 'noise gate' to totally cut sound between sentences and light compression to make the voice warmer and more present. **Usage**: Ideal for interviews taken with a smartphone or videos filmed outdoors. In one click, you go from amateur sound to a result close to a podcast studio.
