Helo and welcome!

For this tutorial i am using a sound file of a vocal recording. I will be using ‘adobe audition’ to edit this sound file. ‘Adobe audition’ is a popular brand of multi track recording software. This software allows you to record, edit and mix sound files/recordings. It has loads of tools to edit/engineer your sound files exactly as you would like them to be.

This tutorial will show you how to use the noise reduction tool to remove unwanted sounds/background noise from a recording or any sound file. I am using adobe audition for this example but any decent sound editor will have this tool.

The first step is to identify an appropriate section of the sound file that contains the noise. A good area to find is that which represents a pause between the speech/vocal. Just like when you take a pause between your sentences or words when you are speaking normally. It is useful to zoom in using the software to get a nice clear view of the part u would like to work with. This is the section that will be used to clean up the entire sound file. Once you have zoomed in on your chosen section it will be apparent that where it should be a silent pause there is actually a quiet noise. This is the section that we will sample and then remove from the entire sound file.

In most cases when you record any sound there is usually a quiet hiss or humming (noise) that can be heard during playback. This can come from the recording equipment itself or from background sounds that are within the range of the recording equipment. It is generally regarded as noise because these are usually unwanted sounds.

As well as noise you will also find other quiet looking parts of the sound file that represent the sound of someone breathing in. You will usually see these breath sounds just before a vocal part begins. These breath sounds will always be recorded with voice recordings unless you use a microphone that only records outward sound. Another option is to have a very skilled vocalist! Some people choose to remove or reduce the volume of this breath sound but that should only be done after you have removed the underlying noise of the entire track first.

So now we will remove the noise!

Highlight the silent pause/noise. This is done in the exact same manner as you would highlight text in a text document. Be careful not to select any of the vocal part when making your selection. You may want to zoom in to guarantee your accuracy for this part of the process. To sample this noise in ‘adobe audition’ right-click on that highlighted section and click on “capture noise profile” from the menu that appears.

This tells the software (adobe audition) what you consider to be the noise (sound frequencies that you would like to remove or reduce). The next step is to to go ahead and remove this noise from the entire sound file. In ‘adobe audition’ this is done by using the noise reduction tool.

Which ever sound editing software u decide to use within your studio setup the method may vary slightly but the basic steps and terminology will be very similar.

Next, click on the “effects” menu at the top of the screen and then click on noise reduction from the menu that appears. Once you have done this a new window will appear. This window represents the noise reduction tool and displays all the options and relevant information about that tool. The noise that you captured earlier will be the default noise used by this tool. You can either completely remove the noise or you can just reduce the noise to an acceptable level using the “noise reduction level” variable shown in the image. If you click on the preview button you can listen to what the alterations will sound like before permanently applying them. This is useful to fine tune the amount of effect you want to apply.

It is important to take care and listen carefully at this stage of the process because sometimes it is possible to apply too much noise reduction. This can effect the overall sound of the file in a way that you did not intend. Once you are happy with the settings click on the OK button and the noise will be removed. Magic!

You will then see complete silence where the silent pauses between the vocal waveforms are. At this stage you will have successfully removed the unwanted noise from the entire length of sound file. This can be seen most clearly by the completely flat line (zero decibels/volume) where the pauses are. At this point you may choose to adjust the volume of the breath sounds discussed earlier if you feel it is appropriate.

It is useful to get rid of noise within all of your vocal recordings because when you have several vocal tracks playing at once it also means you have several layers of noise. This noise can easily go un noticed but it can sometimes slightly muffle other sounds/frequencies such as your musical parts or beats. When dealing with mastering, mixing and balancing the whole mix this is a useful and important tool for a quality production and allows the beat/music to be heard crystal clear.

This informative lesson is to help you to become a highly skilled sound engineer and to create/edit your sounds to perfection.

Welcome to Audio File Formats 101! If you’ve used a computer to listen to music you probably have had some experience dealing with MP3 and WAV files before. And if you have spent a bit of time on the computer recording or editing audio, you’ve probably dealt with many of the other audio file formats. Such as AIFF, WMA, OGG, etc. What’s the deal with all these different forms of digital audio?

1. WAV - Although WAV files can be compressed, most WAV files are usually consist of uncompressed audio, also know as lossless audio files. They are a variant on the RIFF bitstream format method for storing data in chunks. Since these files are usually uncompressed and of high quality, most professional audio experts use the WAV file, which is the universally accepted source audio file format recognized in all audio editing software.

2. MP3 - MP3s are encoded digital audio files that use a lossy compression format. Lossy compression is a method that when the file is decompressed, the data retrieved may be different from the original but is close enough to be usable. With an MP3 the parts of the audio that are discarded in the compression are considered less important to human hearing, (i.e. any sounds below 20HZ, and any sounds above 20KHz). MP3 files are great for the internet because of their small size. You can think of an MP3 as an audio version of a JPEG file.

3. WMA - WMA stand for Windows Media Audio, and is a proprietary audio file format developed by Microsoft, and was introduced as a competitor to the MP3 files format. Although it hasn’t overtaken the popularity of the MP3 format, it is in second place in terms of the number of consumer products that support the playback of the WMA file. One thing that the WMA file format offers exclusively is the ability for the files to be DRM (Digital Rights Management) encoded, which is popular with both music and film corporations.

4. OGG Vorbis - The OGG Vorbis file format is an audio codec that is both open source and free, which was developed in 1998 after word of plans to start charging licensing fees on MP3 files were spread. So, essentially the OGG Vorbis file format is very similar to the MP3 file format, which are both lossy file formats. The OGG Vorbis file format is widely used in video games, saving time and money for the developers, since it is not patented.

All of us listen to MP3s, and probably have encountered the 3 other formats discussed at one time or another. This is definitely not an exhaustive list of all audio file formats, and only covers some of the more popular formats. But this should give you a little more insight on some of the file formats that you use on a daily basis.

Adding music or video streams to your website is a definite plus for revenue generation. Audio-video streams serve two purposes. Primarily, audio and video streaming is used for entertainment. A more practical use of audio-video streaming is for revenue generation by using this technology to promote and demonstrate your products.

Normally, professional website designers are leery of adding multi-media streams to a website. However, the spread of high-speed internet connection throughout the world has finally removed the barrier for the use of multi-media streams. In this article, let us deal exclusively with audio streams. Audio files have different formats. The most popular among these audio formats are the MP3 and MIDI sound format. The question is, “what exactly is a MIDI and an MP3 and what are the differences?” Below is a collection of sound file formats together with their descriptions to help you decide which one to use in your website.

MIDI is a music file type that is considerably lightweight when it comes to the size of the file. The reason for this is that MIDI utilizes the built-in devices in the sound card of your computer. Of course, sound cards don’t sound the same so playing one MIDI file on two computers simultaneously may produce slightly different results. Another problem of MIDI files is that they sound mostly like ring tones of older model cellular phones. Having this installed in your website may give it an amateurish feel. You definitely don’t want to be labeled as an amateur especially when you’re selling something. On the plus side, because of their small size in terms of kilobytes, people who use 56kbps modems to connect to the internet will be able to appreciate the speed at which your website loads into their browsers.

MP3 is an audio file that is highly compressed to achieve a smaller file size. For people using DSL internet connections, downloading a 5MB MP3 file will most probably take less than a minute. For the slower 56 kbps modems, it takes approximately 3 to 5 minutes to download a single song with average playing time. Because of its compressed nature, the sounds produced by MP3 files are not as good as those you hear from your CD. Furthermore, you will have to “loop” a music file if you want it to play continuously in the background while people surf your website. MP3 files are very difficult to loop. The biggest disadvantage of using MP3 files is that they require MP3 player programs. Once you enter a website with MP3 background music, your Windows Media player or Real Player might open automatically to play the file.

The best sound file format in terms of quality is the WAV file format. Using WAV format to record your audio will give you recording studio quality audio. The BIG PROBLEM of WAV is its file size. Even with a DSL or cable internet connection, your browser will have a hard time loading a web page using WAV for its audio stream.

Familiarity with flash files is an advantage when trying to incorporate audio streams into your website. To make the music play continuously, you will have to perform the process of looping. Flash files can be used with either MP3 or WAV but, only WAV files go through the looping process without any difficulty.

As you can see there are many different ways to add background music to your web pages and you don’t have to worry about slow loading pages if you choose the right file format.

It’s quite popular to record your computer screen to make a tutorial, demo or gameplay video in order to share your masterpiece to the world. However, here is one big trouble that once you find out the output file occupies all your hard disk, resulting storage room shortage and system slowdown, furthermore, anyone can stand the long eternal upload progress of your 45-min yet 1GB video?

So now get some tips on what you can do to compress SWF file, please read it before you start to record your screen video.

Attention, all tips get to the root of this matter. No matter what screen recording software you use, all you should do is following the methods then gaining the engaging result.

Tip 1: Adjust the FPS (Frame per second) of your SWF output

This value describes the frequency at which an imaging device produces unique consecutive images.

Generally speaking, for regular screen captured tutorial and demo, setting up FPS to 12~20 frames is enough to produce all steps and movements on your screen. If you want video with more great fluency, just simply add some frames/Second. You can make attempts on figuring out a proper value to balance the video quality and SWF file size.

Tip 2: Optimize images you insert into SWF files

During the editing of screen recording videos, several of extra components might be added in as decoration and additional remarks. The most common one is image and that’s also a key element on altering SWF file size.

You can give preference to the image in JPG and GIF format. Since SWF size varies directly with the bitmap size, BMP and PNG are not recommended for they contain so many pixels lined up in rows, indicating the lesser image compression they can reach.

Tip 3: Use less key-frame animation

The key-frame creates the important frames of a sequence. The more key-frame you use in screen recording, the bigger the SWF file size will be.

To avoid the size increase of SWF files, you can decrease the redundant mouse clicks while recording, or delete those repetitive frame produced by mouse click and keyboard strike in the interface of screen recording software.

So there are two ways to simplify the key-frame. One is combination, it’s widely used in cases when two adjacent key-frames contain similar slide appearance, you can add all actions originally in the second frame after the first frame, then delete the following one frame. In this way, you save one key-frame.

Another way called replacement is rather gimmicky but still impressive and effective. Firstly, make a screen capture for one key-frame slide which differs from the prior one in display and save it as an image. Then import it to the prior frame, set up the right time it appears in the frame tool bar and add the certain effects you want. Check the preview; does it look the same as former state which has two key-frames? And how about the file size?

Tip 4: Choose the ideal audio file for your SWF files

Use MP3 compression, it’s the smallest sound form. In most instances, you can change both the bit rate and sampling frequency to control the audio quality of your screen recording output.

Here for regular narration, we suggest audio file in 22 KHz, 16 bit, single output signal. One more, avoid the stereo sound, it will make your file size double.

Tips 5: Limit the fonts and font styles use

Be careful when you’re about to embed smart font styles into text or button box in screen recording video. The fonts and font styles will make your SWF in corpulence especially when you are trying to embed some unique fonts which need extra room to store in SWF file.

If it’s not essential or on certain purpose, just type all text in one font. You can put the words in different size or various colors, it do little influence to the video size compared with the font mixing.

Tip 6: Pay heed to new screen recording utility

DemoCreator is a really neat screen recording software for web designers, teachers, e-learning workers and basically anyone who is using screen recorders and wants to share their high quality tutorials, demos and video presentations in compressed SWF files.

With the latest version of DemoCreator, it can reduce your SWF file automatically and optimize the whole part of video to export the best quality output demo as far as small in size, according to official announcement to be published in early November.

List of audio File Format
 
What is audio file format or how a music file is stored in audio format. The audio file format provides container to store audio data on device, the device can be computer, music player etc. The audio data can be stored in device in compressed or uncompressed format. The decompressed format is used to reduce the file size on device. One would like to have more and more music files on music players by compressing their file size.
 
Types of formats
 
The current format for music audio files includes wide variety of formats with advantages and disadvantages. The current list of audio file formats are categorized into three major groups
 
List of “Uncompressed audio formats”

1. WAV 2. AIFF 3. AU
 
List of “lossless compression format”

1. FLAC 2. APE 3. WV 4. TAK 5. TTA 6. WMA
 
List of “lossy compression format”

1. MP3 2. Vorbis 3. Musepack 4. WMA 5. AAC
 
1. Uncompressed Audio Formats
 
The well known uncompressed audio format (PCM) is stored as WAV on Windows system and AIFF format on MAC operating system. The PCM stands for “Pulse-code modulation”, which is a digital representation of an analog signal. The PCM has been used in digital phone systems and in computer as digital audio format. Because of its digital sampling WAV format is very flexible and can store recording in original format.
 

2. Lossless audio formats
 
Many Music audio formats compress the audio data so that more and more songs can fit on device. The audio compression comes in two forms, one is “lossless compression” and other is “lossy compression”.
The lossless audio format retains every bit of information of original recording ad nothing is lost. Since no data is lost during conversion that is why “lossless audio format” can not make converted or compressed file as small as file compressed during “lossy compression” method.
 
3. Lossy audio format
 
Under lossy compression method some of the audio information is lost as compared to the original, this makes converted file much smaller. The information which is lost during “lossy compression” is not very important and is least important to the file. One of the format which uses this method of compressions MP3 file format.
 
Audio File Formats
 

MP3: The most popular music format is MPEG Layer-3 format. This is popular for downloading and storing music. Because of Lossy compression the download file is much smaller then the original.
WMA: – The Windows Media audio format is popular with windows system, it was designed by Microsoft.
WAV: To open files with these formats you need ATRAC3 drivers.
RA: This format is “Real Audio format” and is used to stream audio over the internet.
RAM: This is used to store a link to the internet address where actual audio file is stored.
DSS: Digital Speech Standard files.
MSV: – Memory Stick compressed voice files.
DVF: This file is commonly used by Sony dictation recorders.
MP4: Apple uses this format for downloading music from their iTune store with digital right management.
iKlax – Multi-track digital audio format, allows mixing and volumes arrangements.
GSM: This file format was designed for telephone use.
DCT: This audio format is used for dictation, it’s header portion can be encrypted.
VOX: This audio format uses the “Adaptive Differential Pulse Code Modulation”.
AAC: This audio format is based on MPEG2 and MPEG4 standards.
