CPU efficient spectral eq on iphone?
Hello!
Can anyone recommend any auv3s that allow spectral eq ie the graphical editing of frequency bands in an isolated way so that if I pull down one or 2 bands all the way the bands on either side remain un-affected?
Comments
I think the Multi-band Compressors like FabFilter MB-Compressor do that.
@Blue_Mangoo makes one and are cheaper. @4pockets and ToneBoosters too.
All the Fab Filters have EQ in their DNA so you can isolate segments of frequencies and
EQ, Compress, Limit, etc. So one of them will work best but they are the cream of IOS.
The bundle is so powerful but there are many imitators to their approach at lower prices.
Hi @McD
Thank you for this!
Perhaps I am using the incorrect language as I am attempting to find something a bit different than these. Also I dream of fabfilter but unfortunately they are iPad only I believe
I am hoping to find something more like a spectral filter. There is an max4live patch like this but I can’t find the image of the exact interface, I’ll attach a similar interface below
With the spectral filter you can carve out swaths of frequency Very precisely without effecting the nearby frequencies with a bell curve/notch curve etc
Are you aware of anything similar to this on iOS?
You don't need a spectral eq. The better eq's all let you set pretty sharp curves. Be forewarned that no eq actually can eliminate a particular frequency with absolutely no impact on the neighbor. But most good eq's can reduce a narrow band quite a bit.
Having a spectral u.i. doesn't mean it will be better than something that doesn't.
apeFilter can get surgical. It can wild too, so watch out.
Don’t get lost in hype. Just because a spectral eq’s user interface makes it look like it is surgically removing one range of frequencies doesn’t actually mean that it is more effectively removing those frequencies than an Eq with a traditional interface.
Toneboosters is of similar quality to FF and is available on the phone and can be set to cut narrow bands and displays a spectral analysis of the audio.
Performing surgery sure is a good way to learn! At least on audio, not people.
Does @Virsyn BarkFilter come close to using spectral analysis for filtering control?
Might be on sale now so scoop it up if "Yes". Most people that do "minute mastering"
have BarkFilter already for "secret" reasons not to be discussed outside of club membership.
But I've suspected Bark Filter had a lot of potential uses since it's magical and highly intelligent... like Robot Smart as in "2001" where the robot kills the astronauts.
Bark Filter kills bad sound and saves good ones. I assume it can also be used for evil and kill the good sounds leaving "Metal", "Industrial" and "Disco" audio intact. Check it out.
Kill some audio today.
I have yet to find a tool that can remove excess cowbell. I heard of "E-I-E-I-O" but the developer "sold the farm" and the app is now a legend without a trace. Even people that have it can't find it. I think it's Robot mischief.
Barkfilter is a very nice filter. It has fixed eq bands. So, may not be surgical in the way OP was requesting. It is a very nice tool with eq, compression and limiting options.
@annahahn : what are you trying to accomplish? Without knowing more about what the intended application is, it is hard to know what the right tool is.
@espiegel123
Thank you for this!
My goal is to find a tool to reduce frequency masking in a dense track, hoping to carve out space without bringing down nearby frequencies
Usually, you should do that in mixing by adjusting the Eq of individual tracks. It rarely requires elimination of a frequency band...usually only a bit of de-emphasis or emphasis. If you find yourself thinking you need something extreme, it suggests that you may want to re-think the actual content.
And sometimes a multiband compressor is the right tool. Bark Filter might be a tool you want to explore.
And something like ToneBoosters which can be very surgical.
ToneBoosters EQ (or any other EQ that has) notch filters on a high Q setting do the same thing as a "spectral" filter with bars. They're just more honest about how they display the actual frequency curve.
+1 for apeFilter, it's the only one I know that does something similar.
It would be super simple to build a "spectral EQ" as you say (and the term nails its function quite well).
The reason why these are rare might be that such edits don't usually sound very musical.
After reading annahahn's various questions on this forum regarding audio engineering and her continuing issues with 'dense mixes', I'd recommend she use a parametric EQ. They cut away a much larger spectrum, but they're the quickest and easiest way to thin out a dense track.
There's a reason why experienced engineers recommend parametric EQs for audio engineering beginners. They're the easiest to learn. Spend some time with a 3-band paraEQ on various mixes, and soon you'll know what other 'specialized' EQs you need.
Graphic and spectral EQs are specialized tools - experienced engineers spend hours or even days buried in these.
I wouldn't recommend Bark Filter, and I apologize for recommending apeFiiter earlier.
Good luck!
I believe an app mentioned on this forum as an app that can generate enough volume with some settings that can cause hearing loss. Use a Limiter for your own protection. It can drop frequencies AND amplify them to extreme levels. It also does some sweeping across the spectrum with a comb filter and might even have a random option so you don't see the monster before it's too late.
Be forewarned.
I don't understand why you're responding to my post?
In the post above yours, I retracted my vote for apeFilter, and 10 posts above, I said:
Have a great day!
I don't think it's common knowledge about the ApeFilter "wild" behaviors.
Oh... and I have a history of keeping @annahahn posts on the front page with sidebar non-sense. And sure enough, people that know their shit weigh in and we all benefit.
Thanks for playing along.
More cowbell.
Use "Perforator" to make noise relevant.
"Bark Filer" is a secret. Mum's the word.
That's awful.
Well I sent him an email this AM about something else, so I'll certainly pass it along once he replies.
Did the person with hearing loss contact them?
Let me try to remember any other 'wild' apps. There are a few others. Maybe you or one of the other fellows can put it in the Wiki or on the front page, etc. I agree, people should be aware, I just wasn't clear why you responded to me.
Pretty much any digital audio situation has the potential to go wrong. I think a limiter should always be in place during live work. I used to put a hard clip as the final stage in all my AU's. I've taken those out now because users might want to push things between stages and then bring them down later in the chain.
Even if you think you have everything setup well, tweaking an EQ in one AU could drive a resonance in another and it could get loud! Always put a limiter at the end of your chain while working.
That's fair. Singling out one app as the poster boy for hearing loss might not seem fair.
But I did pick a preset in the app and I had to rip my headphones off. Overtime I have set the filter aside and typically grab FilterStep for a "sync'ed" wah-wah sound.
@McD Did the person with hearing loss contact them?
https://apps.apple.com/us/app/multiband-compressor/id1528675416
Yes. They were nice enough to call back personally almost immediately, but the person didn’t hear the phone ring.
I'm using my memory to recall these facts. Act accordingly.
I could see if I can find the thread and insure I have facts and we could
ping the commenter I'm recalling.
Let me see if search coughs up the right thread.
I can't find the original thread but I did find my own comments about
knocking my headphones off with an app. I changed the synth input and
started flipping through the presets on an app and got an earful.
The vendor in question also makes an excellent Limiter app. Get one and use it to protect yourself and your recordings from excess volume and clipping.
I editing my comments here to avoid finger pointing.
