So if I am recording Drumlines (think of marching band percussion sections) do I need this setting turned activated on the external mic? Seems like Drumline has such a large range of sounds from the instrumentation in the ensemble that it might not make sense to turn it on? I really have no clue.

The cutoff frequency definition is at point where the gain is minus 3 dB.

@kevinsjournal 3 жыл бұрын

This is great, thanks for this explanation and example! Do you think a high pass filter is necessary on a mic and can it improve treble? I've used microphones with no high pass filter and it's sometimes very bassy, weak in treble, and lots of hiss noises. Wonder if a high pass would solve those 3 issues? I can edit it in post, but prefer to have it naturally that way since it'd be much easier to deal with.

@AudioUniversity 3 жыл бұрын

It won’t help with hiss, but the overwhelming bass and weak treble might be two sides of the same coin. Low frequencies tend to mask higher frequencies. If you remove some lows, you might find you already had enough highs!

Great info! With today's (8/2021) software, namely Audacity, do you see a need for a physical HPF for spoken voice or will the app do the same thing?

@AudioUniversity 2 жыл бұрын

The HPF built into Audacity is sufficient.

Pink or white noise? Pink noises are slightly boosted in the low end.

@bradleyduer 2 жыл бұрын

Using a filter needs to be done carefully though, as it inherently causes phase shift. That can lead to phase problems in your mix, especially on an instrument recorded with multiple microphones.

@Drizzydid Жыл бұрын

I'm not understanding something. Which has a more drastic impact on sound? Frequency or slope? Specifically in a relativity sense I.e. I understand 100hz at -48db/octave will cut lows more drastically out of a signal than 100hz -12db/octave but what if I set 100hz at -12db/octave versus 75 hz at -48db/octave...would the 100hz eq actually retain more low end since the slope is more gradual despite being at the higher freq of 100hz or will the 75hz retain more low end since the slope is not initiating until lower down in the spectrum at 75hz despite being a more steep slope at that frequency? I just can't sort this in my mind. Thanks. Edit* fixed typo

@B3stfrend67 2 жыл бұрын

Are crossover frequencies and cutoff frequencies interchangeable terms? I noticed at 4:01 you said "cutoff frequency" while the screen said "crossover frequencies".

@AudioUniversity 2 жыл бұрын

I usually use "crossover frequency" to describe the point where the high pass and low pass filter sum to 0 dB. I usually use "cutoff frequency" to describe the frequency where the high pass or low pass filter begin (or reach -6 dB).

@temskee6792 2 жыл бұрын

can EQ substitute high pass filter in terms of cutting the low frequencise?

@AudioUniversity 2 жыл бұрын

Some EQs have a high pass filter built-in, others have a low shelf, and others have a low bell curve. It just depends on the EQ.

u should talk about how to use REW.... REW has too many function and feature, but the usermanual is too long to read...

@edwardhp-channel 2 жыл бұрын

Based on my understanding after watching your video.. this high pass or low pass filters only limit the frequencies ; no matter above or below 0 dB, right?

@AudioUniversity 2 жыл бұрын

They “turn the frequencies down” rather than “removing them”. I hope that answers the question.

I have an Alto powered speaker connected to a Mackie Mix12FX Mixer, the sound is great but when is not playing music you can ear a buzzing anoying noise. i have been trying everything i see on youtube to eliminate that buzzing noise (got new XLR cables, tryed connecting the power with a plug w/o the ground, change location of the outlets......, but i have not found a solution. What can i do?

@AudioUniversity 3 жыл бұрын

I would recommend ALWAYS using a three-prong power plug. My next suggestion is to try a ground lift adapter on the input signal. They are quite inexpensive and they are useful to have in your kit. Here is an example of a XLR ground lift adapter: amzn.to/3wyxjxE I hope this helps!

@dannychiquitoofficial5061 3 жыл бұрын

@@AudioUniversity Where do i connect the lift adapter? from the XLR cable coming from the Speaker to the Mixer? by the way i am changing my Mixer for a Yamaha MG10XU 10-Input Stereo Mixer with Effects, what do you think? i am not professional is just for Karaoke Partys in my house.

@AudioUniversity 3 жыл бұрын

When you mute the microphone, does the buzz go away? If so, put the ground lift between the microphone and the mixer.

@mrdbchops 2 жыл бұрын

Some people (and plugins) refer to these as either ‘low cut’ or ‘High cut’ filters. Interchangeable terms then?

@AudioUniversity 2 жыл бұрын

Often, yes. But sometimes “low cut” and “high cut” will be used to describe a “low shelf” and “high shelf” filter, which is a bit different.

@praneethdhanushka207 3 жыл бұрын

Dear Sir, how are you? Let me time. Your tutorials are very clear and good in quality. I have a small request from you. I think it is better to creat a video on micing of full drum set with EQ setting for each drum. It is really valuable for all audio engineers. I have seen that different engineers are doing different methods. Sometimes it is confusing. Thanks!

@prosperousmados8831 Жыл бұрын

what do you simulate a high pass filter when your mixer doesnt have that option

@AudioUniversity Жыл бұрын

If there are any particular problem frequencies in the lows or low mids, you could use a low shelf or bell curve EQ. Check out this video: kzfaq.info/get/bejne/rcmFnqmQzsyZj6M.html
