Hallo,
Welche Filter benutzt Ihr, um die unnötigen tiefen und hohen Frequenzen abzuschneiden?
Welche Filter sind gut für Sprache?
What filters do you use to cut the unnecessary low and high frequencies?
Which filters are good for speech?

right now i found that the TAP equalizer can be used to remove low or high frequencies from speech... but i'm also opened to suggestions...

regarding TAP equalizer... my issue is too much low frequencies and bass noises.. and usually i set (only) the upper slider (band 1 gain) at 75% (from 100% that is from default) this remove a lot low frequencies echoes and noises (after that i increase the volume by 5 db)

Hello, which tap equalizer do you mean? The normal one or the /Bandwide one?

It is important to be able to adjust the bandwidth. My current favorite is the: Triple band parametric with shelves - ladspa-1204 from Steve Harris' SWH Plugins.
But most of the EQs have only one shelving function.
That takes away too much even beyond the cutoff frequency. I'm looking for a low-cut = high-pass, or high-cut = low-pass filter to cut the frequencies that my voice doesn't contain.

my current favorites from Steve Harris' SWH Plugins:
GLAME Highpass Filter – ladspa.1890
GLAME Lowpass Filter – ladspa.1891

i can't see (ear) any difference from TAP EQ.. and TAP EQ BW

hello,
for me it makes a difference. BW means Bandwidth (octaves). This filter is a bit complicated to set: First Gain in dB, then several lines further down the Freq frequency in Hz and even further down the bandwidth. BW is important and good if you can choose it yourself.
Triple band parametirc with shelves, which is currently my favorite.

You will see and hear a difference. I used Audacity to create a few minutes of white noise. This fairly consistent sound with all frequencies is good for seeing and hearing changes. If you change the BW, you'll see the change very easily too.
Acitvate: View > Audio Spectrum.

And one more thing: I use EQ to improve the sound of my spoken voice. Although I use a good microphone, I have to cut by -5dB at about 350Hz and boost by +5dB at about 2460Hz. As a result, my voice booms less and doesn't sound as muffled. I suppose every voice benefits when enhanced with EQ.

Calf EQ (has HP and LP build in)

Hello,
am very interested. What system are you working on? Do your suggestions (also) apply to Linux?
Which calf plugin do I need to install? Calf-ladspa, or the Calf Plugin Pack for JACK (calf)?

Ubuntu.
And i hardly ever use Jack. I mostly work over alsa.
I've installed the pack from the softwarecentre.

The Calf equalizers have a build in high and low pass. Even high and low selve (often nicer).
Look at this image http://mein-neues-blog.de/wp-content/uploads/2013/11/Calf-Equalizer-12-Band1.png.

In Kdenlive it's not in 'nice visual shell' but as you can see here it's also there.

Hallo zolder,
dann wäre das ja der beste EQ in Kdenlive. Sehr schön, dass man High Pass und High Self unterscheiden kann.
Doch dann geht mein Grübeln gleich weiter.
Woher bekommst Du dieses Schöne Foto des EQ? Muss man in Kdenlive komplett darauf verzichten? Muss man dort nur mit den abstrakten Zahlen arbeiten?
Jetzt muss ich Dir (möchte gerne) Löcher in den Bauch fragen:
Was macht Input Gain und Output Gain?
Dann HP Active 0-5 was macht das?
HP Mode 0-2

Deine Tipps machen mich total neugierig.
Damit Du nicht alles extra beantworten musst: Vielleicht kennst Du eine Anleitung für den EQ und den Compressor von Calf.

then this would be the best EQ in Kdenlive. Very nice that you can distinguish between High Pass and High Self.
But then my pondering continues.
Where do you get this nice photo of the EQ? Do you have to do without it completely in Kdenlive? Do you have to work only with the abstract numbers there?
Now I have to ask you (would like to) holes in the belly:
What does Input Gain and Output Gain do?
Then HP Active 0-5 what does that do?
HP Mode 0-2

Your tips make me totally curious.
So that you do not have to answer everything extra: Maybe you know a manual for the EQ and the compressor of Calf.

Die website von Calf plugins gibt schön viele information. Link hast du schön.
Weiter über die werten, das muss man lernen. Gain, input gain, output gain, decibels, ... das alle sind standart wörter.

Und auch youtube steht voll damit https://www.youtube.com/results?search_ ... lf+plugins

Hallo zolder,
yes, the words are standard, as you write, but the numbers are already very abstract.
And yes, there is a lot on Calf, but the instructions all refer to the graphic compressor. But in Kdenlive everything is so abstract, just numbers and values that I can't convert to dB or anything like that.
How do you know what a good threshold is? In dB it's often -10 to -20dB.
And even more confusing is the EQ.

Yes, i've seen that with Kdenlive your stuck with the numbers and lack the grafic modus. But it still does what it should do.
That's what i mean. If you understand what's done and happening in grafic modus, you know how to set it in number.
If you think threshhold is good at -10 to -20 db, then set it at those values.
That's what i do. I edit audio in DAW in graphic modus, so i understand how to set/edit the numbers in Kdenlive.

And at the end with audio, not to forget. You have to hear what's happening and what's good. Audio production can not be done from view.
If you want the graphic modus then perhaps choose to work the audio in DAW instead of Kdenlive.

And my best tip. Don't do much. How more you do how higher the risk it brings that it will become worse or never be good. Make sure you have a good clean recording for start! A good recording doesn't need much. Less is more.
Good recording = good gear, good mic, good studio, good (floating?) volume setting, in good quality sound (khz, bit), good preparation, etcetera.
