Like many others here, I have used audacity a lot. And I always knew it was a powerful tool. But I never had a use case for it to do anything other than trimming clips or exporting audio recordings. Today was an exception. I make AI Music around lyrics and poetry that I write. And one of my songs had a really obnoxious drone through half the song. I didn't notice it at first, but once I heard it, I couldn't un-hear it. And I realized just how obnoxious it really was. Thanks to your video I was able to find the frequency of the drone and reduce it to almost nothing without compromising the integrity of the song. I think what happened is the AI generated a second octave for the bass line that played simultaneously. I figure this is the case because once I isolated and removed the frequency that was annoying, I found I could actually hear a proper bass guitar. Before the drone overpowered it. I could hear the bass on occasion, but once that drone kicked in, it just got drowned out. I guess what I'm trying to say is thank you for the tutorial. Would have never figured this stuff out without you!

Appreciate this so much - did a live comedy taping and BOTH bars around our venue had bands that night despite being told about the filming (but hey, it brings in patrons, so I get it) and the audience mics picked up a lot of the bass rumble, so hoping this helps minimize it during the non-laughter parts because simply silencing is so obvious in the playback

Thanks Kevin. Great presentation as always. You gave me a possible solution to a problem that I am working on. I must distinguise between to sounds coming from a pellett hitting two types of metal. One sound must be ignored while the other is worth one competition point. I am going to use Audacity to determine the two frequencies and try to filter out the proper one. Thanks again. Have a good day.

I cannot thank you enough for this video, I've been attempting to salvage some near inaudible audio of a court hearing with so many hums and harmonics through it that it looks like Sheldon's doppler effect suit. Plus I'm dealing with very wide volume ranges. Well just the simple ability to be able to zoom in to refine my spectral selections and I've got something that I'm now almost able to hear without effort - even the very faint voices. I didn't read a reference to the zoom feature anywhere else . I actually feel like I am beginning to know what I'm doing now Thank you!

Thanks for showing this off. This feels like a really good tool to understand. It was exactly what I needed. Though, seems like the result would have improved had you focused just on the regions of the bird call with some more precise selections, given it occupies a clear and narrow frequency range-- but it's also good to understand the effect this can have on any overlapping audio.

I just want to thank you for this so much. I'm autistic and I really love a specific song I found, but it has a clip/distortion throughout the left channel that drives me absolutely bonkers and prevents me from enjoying it as much. I've wanted to edit it for some time, but hadn't figured out how while still preserving a majority of the rest of the audio. This allowed me to do so. Sure, there are tiny holes in the spectrograph display between 10k-12k at various points throughout the song, but now I can listen to it in peace.

great tutorial Kevin!! Too bad Audacity doesn't have a type of eraser similar to an image editor or paint program where you could have a type of dot or circle at the cursor and could just erase the fine line of the bird whistle. Might have also been worth doing multiple iterations of the select but make it more narrow to only include the whistle line and do this a few more times as the freq went up instead of the more broad stroke box you were drawing. Thanks for sharing your knowledge. 73 N7KBC Dwight

@Longwing702 ай бұрын
This is really good editing technique if you have a whistle-type noise which runs mainly horizontal where you can pinpoint that horizontal line and then erode it away. But what if the bird is producing chirp-type noise which appears as vertical lines? Very short and repeated chirping crosses multiple frequencies but very briefly each time.

Hi. Nice tuturial to remove 'noise' from background. There are several methods such as using machine learning neural network, such as Nvidia's "RTX/GTX VOice". It is very effective. Off topiv: I like to suggest a simple RF related experiment. 1. Get a portable AM radio. Tune tu lower AM5 band broadcast station, around 500 kHz. 2. Start walking at a straight line, and observe the signal strength level. Observation: We may find the signal strength changes about evebery 1/4 of wavelength. So, somtime, the location/QTH of the antenna/receiver may effect the recetption of certain frequency bands., especially for MF and LF bands. Thank you. 73

In Adobe Audition there are some tool to like paint on that like a brush. then you can remove noises very precisely. Is there something like that ? i wonder if you can "compress" the sound in the selection to a level before the sound of the bird start. then probably your voice and the noise is not reduced but the sound of the bird will be highly reduced.

Great example and approach. Is it possible also to patch in something else in the frequency domain? I'm trying to remove excessive vibrato, and it's easy to see the vibrato wave in the frequency domain, so presumably it's possible to remove that. However that is likely to leave an audible "hole" in the sound just like the change in your voice in your example. If we know exactly what the frequency is of the "ideal" sound, is it not possible to generate that with a precise oscillator, then patch that back into the audacity file using the spectrogram and multi-tools? It would be interesting to see if this works.
@common_man13372 жыл бұрын
Good tutorial, thanks! If I understand the spectrograph correctly, the intense color that shows the bird sound means that those frequencies have a high loudness/amplitude (decibel). Then, maybe it would give an even better result if you could apply a low-pass filter for amplitude in that region of the spectrograph? Then the lower amplitude parts of the audio would not be decreased, so it would probably be less of a noticeable change to the recording. Do you know if such a thing is possible in Audacity?

If your mic gain was too high and the loud parts of your voice are clipping causing the crackle, then no. There's nothing you can do about that. You'll see that in the audio waveform where the top of the waveform will be flattened out at each clip.
