How to filter out the sound of the humming zula in real time and keep only the narrator s voice

1. vlc

audio-filter param_eq --param-eq-f1=233 --param-eq-f2=466 --param-eq-f3=699 --param-eq-gain1=-20 --param-eq-gain2=-20 --param-eq-gain3=-20 --param-eq-lowf=100 --param-eq-lowgain=15 --param-eq-q1=10 --param-eq-q2=10 --param-eq-q3=10

The function is to add three point resistance filters with a Q value of 10, and the center frequency is 233Hz, 466Hz, and 699Hz.

Of these: 6000

You can change to one of the following offload servers:

But since VLC can only add three dot rejection filters, it can't cancel the Vuvuzela sound cleanly, but the volume has been reduced a lot.

2. mplayer

Plus the following parameters:

af pan=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=,sinesuppress=

Frequencies at 233Hz, 466Hz, 699Hz, 932Hz, 1165Hz are filtered out. But since the sinesuppress parameter of the mplayer is not really a dot filter, it doesn't seem to be able to cancel the vuvuzela sound cleanly either.

3.Television set.

If you watch ,...... on the TVNo way......Input the sound into the computer and process it before exporting it......

Turn off the sound of the TV, explain it yourself, and practice your mouth, which is good.

I want to filter out the voice of the CCTV commentator, especially Duan Xuan's voice, leaving the sound of the wooing group.

This problem has been reflected by many countries before the World Cup, we can't stand it from TV, do you think the players on the scene can not be annoyed? I feel that the lack of goals has a lot to do with this sound, and it has seriously affected the form of the players. Many countries have already submitted their applications, because they will be cancelled!

yes, it's really noisy. Like bees barking, it was a pleasure to watch the game, listen to the fans shouting and feel the stadium, this is a real TM fuck. To filter, only do not listen to the commentary.

This is a South African tradition, with the consent of the World Football Association, call ** to South Africa ** Zuma and tell him not to blow !!

Real-time filtering is unlikely. You should add to the atmosphere!

Send me three thousand suona hands in Shenzhou to cover the sound of disgusting green-headed flies!

There's no way, huh? It's like the Olympics, and other countries can't understand it, don't you take care of it?

The 233hz, 466hz, 932hz and 1864hz bands can be filtered out, there is such software:

Simple, turn the sound off! Of course, then you can't hear the live sound, and if you want to listen to the live sound, then you're going to need professional equipment.

There is no such method at present, you can only listen to the Chinese explanation, in fact, I can't stand it.

If you remove all the voices and then dub them separately, it's relatively simple, and VideoStudio can do it. If you just want to remove someone's voice (other voices are retained), it is not something that ordinary people and ordinary software can do, it is an extremely complex process, and it requires very professional personnel and software, and the film stunt production company should be able to do it!

Is there a solution, what software can.

A lot of software has this feature.

The easiest way is to record with the audio recorder that comes with Windows.

It is also possible to convert with a format factory.

Use VideoStudio to separate the AV and then edit it.

There's no way to do that. Since the sound and background** are synthesized on the same track, they cannot be separated, so they can only be deleted together.

If the audio file contains two channels, with the sound on the left and on the right, it can be easily removed, but if it is a left-right mix, there is no way.

You can extract the sound from the movie first, and then:

With Cool Edit, vocals can be eliminated inside.

1) Boeing interface, file, open audio file.

2) Select Boeing All and then select Effects. Waveform amplitude. Channel remixing3In the dialog box of the mixer, select Vocal Cut4) Click Preview Audition, you can move the small sliders of the left and right channels, 5) Click OK when you are satisfied.
