Questions about effect "Filter" in Maschine 2.5

Hi everyone,

I'm currently working on a project and in my sample I have a trumpet sound that is making clipping and therefore not very enjoyable sound overall.

So I was then thinking that I should EQ my sample and also putting a filter, which is in that case a low pass filter. I've been trying since weeks to tweak that high frequency sound from my sample with no luck. I recently used a audio analyser (Voxengo SPAN) and I was "playing" with EQ / Filter LP.HP to analyse the spectrum and see how it changes the sound.

However, I noticed that actually the filter LP/HP from maschine was actually not accurate at all. Correct me if I'm wrong but putting a LP filter at 800hz on my sample should get rid of every frequencies above 800hz. Same thing about a HP filter, I wanted to get rid of those "30hz to 60hz" frequencies from my kick. I therefore set HP filter at 60hz.

For both example, once I checked my spectrum, those filters were not accurate at all. In fact, I had to set for instance my HP filter way more than 60hz (roughly 100hz) in order to get rid of those very low frequencies.

Does anyone notice this behavior ? Am I missing something or this "Filter" effect coming from Maschine is not accurate at all ?

Cheers!

No. The filter cutoff is the frequency at which output of the filter would be half the input (-3db).
Then, the attenuation is a slope. A one pole filter has a slope of 6 dB per octave, a two-pole has a slope of 12 dB/oct, 4-pole 24 db/oct, etc.



Hope this helps.

 

It does actually .. thank you!

I learned that in secondary school lol..

Cheers

 

Try using a brick wall filter

if you are clipping, surely the preferred fix is to reduce gain.... eliminate the clipping first, then use filters for tonal change.

 

You may also want to reduce the gain and look at using compression to regain that precived loudness level

Here's some settings and lit if you do decide to use compression

The other options are using automation to control the levels, or a recovery anti peaking vst like the one in acon digital's restoration suite

I usually don't have some much issues to EQ my sound but I have a project currently with a sample coming from a song of Mile Davis. I love the sample but I'm struggling so much to EQ the high frequencies. I tried filters, EQ, limiter, everything I can but I'm still getting red clipping once we ear the trumpet. I'm about to give up on that one.

 

You either want to compress/limit the offending sample or simply lower the volume of everything else in your project so that you can hear the sample at the correct level without clipping. I usually start with every track set to -16db by default (or lower) in order to give myself enough headroom. Turning the overall volume up is easy in a digital system so best to start low!

If rogue frequencies cause clipping problems it's usually the lower frequencies that are the issue. I have had rare experiences where some badly-written plug-ins caused massive aliasing creating high energy low frequencies that were below the audible spectrum but caused everything later in the chain to clip like mad and sent compressors mental. I remember Audio Damage's Kombinat being a particular offender. There's a very outside chance this could be your problem in which case the solution is actually a high-pass filter after the offending plug-in.

 

have NI improved the filter quality of the build in maschine filter?

 

Thanks @muleskinner , I didn't think of this problem like the other way as you said, meaning lower the low frequencies instead of focusing on the high ones that I don't really like.

It's like a part of the sample is having very "raw" trumpet sound, (typically mile davis sound) and for some reason this high frequency doesn't sound nice for my ears so I'm trying to make them smoother if you know what i mean.

 

"Brass
This can be applied to all brass in general, but particularly with trumpet and trombone in mind.

100 to 200 Hz - Boom/Mud: This is particularly pointing at the trombone, as it sometimes shares the range of the bass and the rest of the rhythm section, but rarely functions in that purpose. Getting it out of the way is usually best, as this range will serve little except to cloud most mixes
4,000 to 10,000 Hz - Brightness: This top end can brighten up a dark horn section. However, trumpets can nearly take someone's head off in this range with a good blat, so managing this band is key here"

Hope this helps

I'd have to hear the sample to tell you how I'd process it specifically

Thanks for your replies guys.

Here is the sample: https://drive.google.com/open?id=0B6A3GaIJZuQKWkhIRWVMVDMydms

I don't really the sound of the trumpet when it goes high. Sounds like flat, you know ?

 

You may want to use Melodyne to shift some pitches, if it is flatness is from the filter you're hearing, you are loosing overtones, harmonics, and dynamics.
