- Let's take a few minutes to talk about the high-pass and low-pass filters in Audacity. High-pass and low-pass filters are an effective way to attenuate unwanted frequencies above or below a set point that you determine. It can be another way of eliminating or reducing unwanted noise in your podcast.
You can find me on the web at audacitybootcamp.com and my Audacity Bootcamp: Beginner to Advanced video teaching series is at www.udemy.com/course/audacity...
I kept seeing low pass and high pass in DAWs everywhere, but I heard it again in a CZcamsr I watch and I got really interested. Thanks for the help!
thank you so much i seen more than video to understand High/Low pass filters basic understanding and you were the one who explained it clearly. This is the power of teachers!
Perfect demo of this - thank you
This is great, I'm trying to fix audio with my regular DSLR recordings, shopping and looking for a new mic and confused about the 2 terms, thanks for explaining it!
I guess I'm kinda randomly asking but do anybody know a good site to watch new series online?
Thanks a ton for this video. You have a great voice and you explained everything so well.
Thank you!
Great lesson - great style - luv it 👍
In the part where you set the low-pass frequency to 600 Hz then reduced everything above that by 36 DB, it sounded as if you had a mask placed over your face! :)) I mean, there have been times where I've heard recordings of people talking with a mask on, like for example a diver talking underwater with a full-face mask, and I always made the comment that it sounded as if they added a low-pass filter onto their voice. Well that's pretty much what happened except that they did that with an actual physical object instead of achieving the effect electronically.
Anyways, this was a great explanation; I was always a little confused about the difference between a low-pass filter and high-pass filter. So this video explained it pretty well. I've also heard of another type of filter called a "band-pass" filter. I guess it's similar to what you explained here, but not by much?
Thank you so much for the GREAT tutorial! Subscribed :)
Thanks!
What all effects do u do in your audio
Hi, I'm beginner in audacity. From where i can download all filters effects that you have ?
Seams like i have jus basics. I can not find high and low pass filter
That was so informative thank you. But I have a question what if i want to amplify mid range frequencies what should do ?
Micheal, the Graphic EQ or Filter Curve will allow you to grab those mid-range frequencies and amplify or attenuate them.
When i apply HPF it messes with phase and step response. Could you explain what effect it has exactly and if its detrimental for music ( if i apply 24 db at 15 hz for example ) ?
It's not detrimental to music in any way. Audacity was built around music and for music. Using it for speech only (podcasts) is a bonus. Are you familiar with the Audacity User's Forum? You might want to see if anyone else is experiencing that same problem and how they solved it. This is the first I've heard of it. That URL is forum.audacityteam.org/
This is great 🔥
However as a beginner I don't understand many things. Pls make a video what is Hz and Db. I think you are good at explaining.
Thank you. That's a good idea and one I'll be working on.
Take this with a grain of salt because I'm not an expert but my basic understanding is: Hz is a measurement of frequency (i.e. how many times something happens in a second, in sound we're talking about how many cycles or little hills in a wave happen per second.) It's not quite the same thing as pitch, but in general you can kinda equate the two. High frequency sounds tend to sound higher pitch (if it's not past our hearing threshhold.) dB is a relative scale used to measure "attenuation" which is basically how much a sound wave is absorbed or reduced. Since it's a logarithmic scale the numbers are kinda confusing, but in general 3dB of change is either half (-3dB) or double (+3dB) the original sound's intensity. Maybe Audacity Bootcamp could correct me on that? Great video!
Thank you. Your explanation is awesome. +1 Subscriber
Thank you!
amazing video, thanks a lot!!!
Thank you.
I've got a question. Assuming I put every frequency below 1kHz down in the equalizer, do I get the same effect as a low pass filter set to 1kHz? Or what is the difference?
It can be. It would depend on the dB rolloff you have set in the high-pass filter window when applying it.
Hello. is it possible to apply the high pass filter effect but in such a way that it is introduced into the audio gradually? kind of like the effect that DJs use ...
No it's not. It applies it equally to your selected audio.
@@LearnAudacity ok thx
Not sure if ur still wondering but you can use filter curve..
Amazing Tutorial. What software have you used for the screen recording and editing the video..
I record my screen audio on my Zoom H6, edit it in Audacity, and sync to the video using Camtasia. Thanks for asking.
@@LearnAudacity Thank you
thanks 👍🏻
I used high pass and low pass filters to remix a version of a certain song that was only available in mono into stereo.
This explanation like all your vids was awesome. I have a piece tha'ts shaky, or vibrating, how can I remove that ?
Thank you. I'm not sure what you mean by shaky.
@@LearnAudacity its like its on repeat distorted
(I don't use audacity, I use after effects but still) this video was extremely useful, so thank you so much!
You're welcome. Thanks for letting me know.
Can you apply a gradual high pass filter?
Yes, if you use the Filter Curve instead. You can roll off your unwanted frequencies any way you need to, using that method.
im looking to have a natural sounding transition between a very high pass to the unfiltered audio, how would this be done
I'm not sure what you mean...
@@LearnAudacity think the way czcams.com/video/TbsBEb1ZxWA/video.html fades from low pass to unfiltered, but the other way around
When u say pass and intinuate what do u mean
High pass passes higher frequencies while attenuating or reducing the loudness level of lower frequencies. Low pass does the opposite. It passes lower frequencies while lowering the loudness of higher frequencies. I hope that helps.
@@LearnAudacity yeah that did lol. So if I wanted to get rid of the high moments or lower them I would do low pass and it wouldn’t affect the low frequencys
walkie talkie sound effect is simply a high pass filter with some distortion
Low pass= radio
High pass= yelling through walls
