The high pass filter reduces frequencies below a certain level. It can be useful to remove rumble and other lower annoying noises in a recording. This uses Audacity
I'm trying to edit a podcast where there were a few microphone bumps or table kicks and they are recorded at the same time as someone is talking. I literally have no prior knowledge on audio editing, and everything I know, i learned this morning. Noise Reduction, Equalizing, and leveling. Anyway, can you direct me to a video, record a video, or respond to this in a way that makes sense to an uneducated editor on how to remove these bumps or table kicks? I was told to use a spectrum analyzer, but I don't know anything about frequencies and everythings confusing, and I can't figure out how to use spectrum analysis in Audacity.
I literally just saw you in the LibriVox forums, Phil. Hey, your voice also sounds familiar. Did you by any chance narrate "six creepy tales by Edgar Allen Poe?"
It's been a quite a few years, but yes I did indeed narrate those creepy tales. Don't know if they were really creepy, I just loved them. Glad to have you as part of LibriVox Kevin. Hope you are having fun.
Question for you. I’m really new to audacity. I’m attempting to make a subliminal recording but all I can find are videos saying to lower the volume of the affirmations to below the masking music. What I’d love to know is how to alter the affirmations so that they play above human hearing levels to create a silent subliminal. Can you help?
I've never made a subliminal recording so am unable to suggest anything to help. I don't even know what the human hearing levels are set to. Good luck.
Your voice is absolutely wonderful. Can you please tell me what microphone you used for this recording? I realize of course that you would sound great on any microphone but us plebs need all the help we can get and my cheep microphone sounds as if I can only afford to live in a cave, so I need to upgrade. Thanks, Sally
Sarah Chopping How absoultely sweet Sarah! thank you for the wonderful compliment. I used a Yeti Blue microphone that cost me about 100 dollars US two years before so it isn't very cheap. But it does give a very nice bass sound and I love it. The LibriVox forum has extensive comparisons of micro[hones and many of them sound great and cost less. Best of luck and keep recording. !!!!
Hi Phil! Thanks again for sharing!! I was wondering if there is a way to go back to "default settings" after trying to make unsuccessful changes to a recording (after having saved it in Audacity and closing it). Example, one of my recorded chapters makes a "wah-wah" sound, similar to when one window is cracked open in a car. Any suggestions? Thanks again!
Hi Bubbly (I bet your voice is just fabulous!). by default I assume you mean to go back to the 'original' recording before messing with it. Nope. Once you have saved an AUP, whatever is there is there and you will need to mess with it some more to remove the wah-wah. Which is why the 'preview' button is just wonderful to check out any changes before saving them. (And stop going 'wha-wha' into the mocrophone or recording in a moving car ..just kidding )
Phil Chenevert But the car is where I do my best recordings! Haha! Thanks for the info Phil. I know I'll still be able to fix it somehow. I guess that's the beauty of Audacity; eventually, the recording WILL sound good!! I narrate through ACX mostly but would love to do more commercials - they're sooo much easier!! Haha!
I use a high pass whenever my ears tell me my track has too much rumbling bass. so at the start or the middle, it doesn't matter. I usually try a portion first to see if it helps, then do the whole track.
This is helpful, thank you!!! But what if I want to make audible noise frequencies outside the range human ears can process as i know spirit voices sometimes are outside the range of frequencies the human ears can hear and process???
Interesting, but Humans sound equipment wont do that in this case ;). First, you need a portable frequency counter, 10 Hz to 2.6 GHz costs around $50, once you have a known frequency band you can target a radio transceiver and capture it to a PC. BEWARE, you might get caught in the process. My 2 cents
No. Noise Reduction only reduces the volume in 'silences', the space between speaking . High pass filter reduces the volume of all freauencies below your set point for the entire track (or whatever part you select). so high pass flter reduces your spoken sections as well as the silences be tween words. That's the best I can explain it. but there is a difference!
@@cajun5454 Thanks Phil. So applying high pass filter will reduce the low rumble below the selected value (say 12 db) throughout the track. I suppose I can use the Amplification effect after I use the high pass to increase the overall volume of the track. Thanks Phil. You are a very very helpful. Do let me know what you mean by 'but there is a difference' if you can.
Just that there is a difference between the two. Not sure why I added that comment. And yes, high pass filter will reduce the low runble just as you said and then you can amplify the whole track. easy peasy.
Would this be good to remove background/ambient noise like pc fans etc? The reason why i ask is because i have a condenser and live in a house with lots of noise and with the noise removal i always end up reducing alot of the vocal quality( like it´s underwater) in order to significantly reduce the background noise. Obviously getting a dynamic mic and treating the room would be much better options but would this be a viable option?
