Important devices and highly useful audio editing clean up

Soren constantly helps Udemy's instructors fix their audio tracks. He's so knowledgeable in editing, and fixing tracks so they're usable. His course helped me edit many minutes of recorded audio from a client that had constant fan hiss on it. His suggestions cleaned up the file so I didn't have to ask my client to re-record several hours of content.

I highly recommend Soren as a great instructor. Soren's idea to easily block background noise from the sides and back of a mic is something that I really needed. His straightforward instructions made it really easy for me to save $200 to $800 (which is the price at B&H audio) for a similar noise reduction device. I spent under $10 on his solution, and it was fast, easy and fun to put together. I highly recommend this course to any one who wants to know how to do recording and noise reduction better, and to anyone who wants to save considerable expense on audio recording equipment accessories.

I recommend this "how-to" course. It will help improve your voice recordings.

This course deals with a major issue that plagues voice recordists: noise. It shows you how to reduce noise at the source, by reducing what gets into your microphone, then how to clean up what's left with your recording software.

The most fun part of this course for me was the Do-It-Yourself intro to building sound modifiers, like a pop filter and sound-proof surrounds for your mic. I thought the pop filter design was particularly ingenious, and all of these DIY projects could save you a lot of cash while greatly improving your sound.

The section on using audio software like Audacity or Sound Forge, to clean up noise in a recording, was also useful. The instructor used features like normalization, EQ and compression that are widely available and work similarly in most recording apps. This is the only place I felt the course fell a little short. There was a lot of normalizing and tweaking of EQ without much explanation, and that may mystify some people. In the case of a track with one or more transient peaks (from lip smacks or other extraneous noises) normalizing won't appear to do much at all. I wish the instructor had mentioned to go through the audio and manually edit out such noises before normalizing.

There's some good advice in the summary bullet points at the end of the course, and I could see this material growing into a more detailed sequel.

Overall, I enjoyed the course and would recommend it as well worth the $19 tuition.

Build things to remove noise from enter your microphone
3 Lectures 10:38

In this lecture you will learn how easy it is to build a pop filter from basic things you often have in your home.

In this video I used a plastic frame, double sided tape and a fabric that is normally used on the front of speakers. You can use what you have as a frame for the pop filer. The shape do not matter much.

The fabric must be thin and so the sound go trough it. To fasten the fabric to the frame you can use what you have, like glue, tape, needle and tread, stapler.

You also need something that is holding up the pop filter in front of the mic. I used a thing I have when I solder.

After this lecture you will have a very good pop filter to your microphone so you will not get bad recording due your air from the mouth will hit the sensitive microphone.

Build pop filter for your microphone

In this lecture you will learn how easy it is to build a acoustic soundproof shield for your microphone.

The material I use here is a sound reducer mat that is often used in cars. One side has a aluminiumfolie on and the other side is pre-glued that have a safety film over it.

I also use a foam for car stereo speakers. Both of those you should easy find in a store for cars parts.

Its very easy to make this shield and its up to you where you want to use it.

Beside it allow less noise to the microphone, it can also be used to shield of a computer or whatever you want to reduce the noise from.

Build a acoustic sound shield for your microphone

In this lecture you will learn how to build a simple desktop sound booth for your microphone. It will reduce the sound the goes into the mic from the side, back, bottom and the top. This leaves only the front of the microphone open for sound.

You can use this sound booth with the pop filter to reduce even more bad sound. This sound booth I made is for a small microphone, but you can built it so your microphone do fit in the sound booth.

The material you need for this project i what you can get, but you need some sound reducer foam, like what you used on the acoustic sound shield.

When you have made this you can use it where you want to do a recording, as its small and easy to move around.

In this lecture you will learn how to remove the background noise.

You need a audio editor for this steep. I use Adobe Audition, but you can use Audacity or any audio editor you want.

The sample I use is from a Samson GoMic that I made sure it would have background noise in the recording.

You can get a lot better sound from this mic, but for this test I needed to have it sound bad.

My main microphone is an Audio technica At2020 with a Steinberg UR22 USB audio interface. I also use my sound shield and my pop filter.

The goal of this lecture is that you shall know where the noise is in the audio clip and how to remove it.

In this video I will show how the Shure MP58 microphone will be when you recording with it.
This video will not have the audio quality that you can get, as the reason for this video is to show how it works when you have background noise, bad environment and I am holding the microphone in my hand. I also do not use a pop filter. If you do what you learned in the other videos you should be able to get much better quality in the recording. The microphone cost about 50 dollar, but it depending on where you buy it.
