For really loud settings , my Preamp will be a big help . Use the Limiter and a set of Pro mics .

Hi everyone, I'm new on this board and I was looking for some help about a Tascam DR07.

Well I wanted to know some details about the Low Cut Filter, in the manual it says that it decrease the sound of wind.

But my question is for example i'm recording an interview in a room where the air cond is pretty loud, what filter should I choose? 40hz 80hz ou 120hz.

Also could someone explain me about the Low Cut Filter.

Thanks

Use the 120 hz , and have the 07 as close to the interviewees as possible , then after importing to your Mac/PC , use Audacity , to remove any remaining noise , with the Noise removal features in Audacity ( freeware ) Start with fairly LOW thresholds in the noise filter ( in other words a LITTLE at a time , instead of one BIG chunk )

Step one , Highlight an area where there is ONLY the noise , then select from effects the Noise Removal -> " Get Noise Profile" it will use the highlighted area to identify the noise and seperate that from the audio .

Step 2 Highlight the entire File ( "Select All ") then-> Effects-> Noise Removal-> settings try a Low setting at first 3 Db , or so ( you will be surprised at what a difference it makes ) or do it in 2 DB increments .

Enjoy your pristine interview . export as Wav burn it to CD

Thanks for the reply, but it was just an example. Using the 120 hz filter is going to reduce unwanted noise more than the 40 hz filter or the opposite?

For instance if I would like to record the sound of the engine of an aircraft, there is a loud sound of air cond on aircrafts, but at the same time I want to keep the sound as high as possible without having the wind cutting the recording.

Surely what you have to do is to use FFT to subtract out the background?

[jag93]

Thanks for the reply, and what about the Low Cut filter (sorry i'm not really a specialist in sounds or music) when applying the 120hz filter, is the sound going to be quieter than when I apply a 40 hz filter? and what are the differences between the different frequencies?

easiest way to find out is to make sample recordings and try the various filters and cutoffs and see what YOU like, everyone hears things differently, and has different expectations from a recording. One mans answer may be another's dilemma, in the time spent looking for answers you could have tried a few things out, we try to help as much as possible, but trying it for yourself is the ultimate test,

Have fun

40 Hz removes sounds with frequency lower than 40 Hz. 120 Hz removes sounds with frequency lower than 120 Hz. 40 Hz is lower than 120 Hz, so the 120 Hz filter will remove more of the sound.

The trick is to remove the sound you don't want and leave the sound you do want. For voice recording, 120 Hz is probably what you want much of the time, but you might find that it changes male voices.

There are two things you really want to filter. First, if you have wind noise and don't have a wind screen, that can peg the signal, and you have to filter that. Second, if there are bumps and clunks picked up from floor, table, handling, etc., you probably need to filter that noise before recording. I don't think you will be able to remove the noise of a whoosh of air from an air conditioner. It's too high to filter (the frequency range overlaps what you are recording). But if the air is hitting a microphone with no windscreen, that will produce a low rumble that you need to filter. Filtering with Audacity after recording may help somewhat.

Thanks for the reply, I've tested with the 120 hz filter and as you said a lot of sound is removed, and the overall sound, sounds distant.
