Hello! I am very new to audacity, and I wanted to edit this white noise on youtube for my own use during power outages. However, I can’t stand the very low mechanical hum that plays under the fan sounds, which my real machine does not have. I can’t exactly use noise reduction, as there’s no point where that noise would ever be isolated to take a sample. Thanks so much.
Audacity can generate white noise, pink noise, and a couple of others. You can also generate white noise and then use the Graphic EQ effect to shape it as desired:
Generate → Noise
That YouTube video (v=nHJVDAkLS10) is not really white noise: it has resonance ~500Hz
[emulation without hum. Loopable]
Since there’s no isolated part of the track where the hum exists by itself, we can still try other techniques to reduce or remove the low mechanical hum while preserving the fan sound. Here’s how you can approach it:
Use Equalization to Reduce Low Frequencies
The hum you’re hearing is likely in the lower frequency range (typically around 50-150 Hz for mechanical hums). You can use an equalizer to reduce or remove these lower frequencies while leaving the fan sound intact.
Equalizer is too blunt a tool to remove hum. Spectral editing is more precise …
