Subject:Pop and Thumb sound on Pronunciation of P's and F's

Dear Sound Forge UG:

I am a newbie to Sound Forge. I am using Sound Forge to edit a couple of wave files. However, I ran into some difficulty.

Problem: I cannot remove popping/thumbing sound in a few voice over wav files.

Action: (what I have done)

1. Tried lowering EQ below 125 hz to remove noise
(did not work)

2. Tried Sonic Foundry noise reduction plugin to
remove selected area of noise (did not work)

3. Tried noise gate to remove selected area
(did not work)

4. Tried click and crackle removal to removal
pops (did not work)

What am I not doing right? Your suggestion will be highly appreciated.

VT

Unfortunately this noise is very difficult to remove once you recorded it this way. I have some suggestions to avoid this problem in the future. In the future when recording vocals use a "Pop" filter placed infront of the microphone to reduce that unwanted "P" sound. Another good technique is to place the microphone above the persons mouth with the diaphram pointed down towards the persons mouth. Then you must instruct the person to look straight ahead and not look up towards the mic. This will cause the "P" sounds to travel below the diaphram of the microphone and that annoying "pop" sound will not occur.

I've never had to deal with these "P-Pop" sounds using these 2 techniques when recording vocals and voice overs.

You can also use the Multi-Band Dynamics found in the effects menu. There is a preset for reducing loud plosives.

Some preproduction tips.

Post production processing is not the choice for most people, but it can work.

Inexpensive solutions range from placeing the microphone, sometimes to catch reflected sound or at an oddly oblique angle to using a good "wind sock". A pop filter shouldn't cost more than 30 bucks, or you can make one out a nylon and wire hanger or an sowing hoop.

Click or cut and paste the link below to see what a pop filter looks like.

Basicly if breaks up any large "gusts" of air that could over actuate the mic.

the best solution is to not have them recoreded in the first place. I know it may be impossible to re-record the voice, so in that case try this:

find the areas visually, select an eq and roll off everything below 150 hz or so. (it needs to be a low cut or high pass...not just pulling down an eq band). You can even try going to 250 hz. Try doing this *just* on the sound itself.

The problem with using any dynamics with it, is you'll hear the recovery since the amplitude or volume of the piece will drive the compressor so far into gain reduction.

I've used the eq technique on some important broadcast material over the years with pretty good results. Best wishes!

Hi VT,

Like everyone has suggested, it's best to avoid recording plosives in the first place, but you can try using compression to remove some of them. Just select your data, choose Effects>Dynamics>Multiband, and then choose the Reduce Loud Plosives preset. That may help to reduce or remove some of the noises.

Best,
Scott
