Audio Video Interleave (AVI) is a multimedia container format created by Microsoft as part of its Video for Windows (VFW) technology. AVI files can hold both audio and video data in a file container that allows simultaneous audio-with-video playback. AVI files support several streaming audio and video similar to the DVD video format. AVI is a common format for audio/video on the PC and can be supported by some standalone DVD players. It is not ideal for use as a general purpose container.

To play an AVI file on Windows the type of decoder on the computer must be determined to portray the video. AVI files consist of a property called a FourCC, which has four letters, determined by the kind of encoding used. VFW decoders then register particular FourCCs with Windows, letting it know that they can decode video in those formats

AVI files can be created with no compression, resulting in extremely large file sizes, but with no loss of quality from the input video to the saved file. This also requires no codecs to be installed, either for saving or playback; as such it is recommended to use a Lossless Compression format instead.

AVI files can be easily converted to DVD with the use of convertor programs available on the internet. One example is the Avi2DVD which is a graphic user interface that uses freeware tools and various freeware encoders or CCE to perform conversions. Other types of convertors are Convert Genius, Adobe Premier, Nero, and Pinnacle.

CDA which stands for CD Audio, is not an audio file format like MP3 or WMV. Rather, when an OS detects an Audio CD, it reads the basic information recorded on the CD, including the number of tracks, CD Text if available, total duration etc. To access the audio tracks, it also creates CDA labels, though the labels are not real files and are impossible to copy by selecting and dragging them. So to convert CDA to MP3, you will be required to rip your Audio CD, as CDA labels cannot be converted at all, as they contain no audio information.

Things you will need

AudioConverter Studio

Instructions

Download and install AudioConverter Studio to a known location on your computer. Run setup and follow the on-screen instructions to install the application.

Insert the Audio CD that you would like to convert to MP3. Open AudioConverter Studio. When the Wizard appears choose ‘Rip an Audio CD’ and then select ‘next.’

AudioConverter Studio offers the option to set output folder (1) and filename format (2). Use any folder on your computer; the filename format option will allow you to set a pattern for filename and folder names. That is your converted files can have user friendly names and sorted by folders according to artists, album name, etc. The information for filenames and folder names will be taken from CDDB, of from CD Text if present. Select ‘Next.’

Another wizard page will pop up; here, specify MP3 file as the output format, setting your specified MP3 bit rate as well. Note that they ‘prelisten conversion’ box, if checked, will make the software convert only a few seconds of each track. To convert full tracks, make sure that option is kept unchecked.

When the final page of the wizard pops up check all settings again, and if everything is OK, click ‘finish’ to rip the Audio CD. The converted MP3 will be found in the folder you previously specified.

MPEG-4 Part 14 or MP4 file format, or as it is formally called ISO/IEC 14496-14:2003, is a multimedia container format standard designated as a part of MPEG-4. It is prevalently used to store digital video and digital audio streams, specifically those defined by MPEG, but can also be employed to store other data such as subtitles and still images.

MPEG-1 Audio Layer 3, or MP3 as it is typically called, is a patented digital audio encoding format which uses a kind of lossy data compression. It is a widely used audio format for regular audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music using digital audio players.

There are instances when converting MP4 to MP3 may be wise, especially if you are using a digital audio player that does not support MP4 playback. To convert from MP3 to MP4 you may either choose to buy software that can do this conversion easily, you may also use free software that can be downloaded from the internet or you may use iTunes to carry out this function. When using iTunes you will have more control over the conversion as it will allow you to set the bit rate and overall sound quality. Below are a list of instructions that will help you to convert from MP4 to MP3 using iTunes.

1.Open the iTunes application.

2.At iTunes, select the song you would like to convert.

3.Go to your iTunes menu bar, select Preferences, alternatively you can press ‘Command’ and ‘comma’ keys, i.e. “?,”

4. At the Preferences window, select the ‘Advanced’ option:

5.At the ‘Advanced’ section, click on the button that says ‘Importing’ and then where it says ‘Import Using’, choose ‘MP3 Encoder’

6.Under Settings, choose ‘Custom’, you can choose any of the options there, but ‘Custom’ settings ensures you set the right bit rate.

7.If you’ve selected ‘Custom’, you will see ta window pop up; ensure that your Stereo Bit Rate and Sample Rate are to your desired settings, it is best to use a setting of 44.1 kHz for the best audio quality. If you are uncertain about custom settings then use the default settings.

8.Close the Preferences window; h before doing so ensure you have checked the correct song.

9.At the iTunes menu, select Advanced -> Convert Selection to MP3 and the conversion would start.

10.Once iTunes has completed the conversion, you will see two songs of the same title.

11.To confirm, select that song title and press the ‘?’ and ‘i’ keys to view the file information, and you should see a new window with the file details.

In the 1990s, the AVI and WMV formats were introduced by Microsoft. Since then both formats have been staples for computer internationally. AVI which stands for Audio Video Interleave, was introduced in the year 1992 and is technically known as a container format. being a container format, AVI can include both video and audio while allowing synchronous playback. AVI files can be found online as music videos, TV shows, streaming videos and even full length motion pictures. On the other hand, WMV stands for Windows Media Video and was developed by Microsoft specifically for streaming. However, WMV can also be saved to a hard drive or disk media for playback with Windows Media Player and other typed of players such as Winamp, DivX and VLC player. The file formats are widely used for two reasons, the first being, they are easily played in media players like Windows Media Player, that come bundled with the Windows operating system. Secondly, they are easy to compress and can be uploaded, downloaded or streamed via the internet. The process of converting AVI file formats to WMV file formats is relatively easy and it only requires conversion software.

Things you will need

Conversion Software

Instructions

Install and Open conversion software on your computer to convert either an AVI or WMV file.

Choose the type of conversion that you would like to achieve.

Load the AVI source file that you would like to convert to WMV. Usually the software will prompt you to browse of quickly select the file from a folder on your computer. A lot of applications will also allow you to drag and drop source files into the application window.

Name the destination file and make certain that it is saved into a specific directory.

Once you’ve completed steps 1 through four, you may choose between additional features. Each software will have its own features, so before using the software, look through the bells and whistles that the software offers.

Once you have made all your selections, you may begin the conversion process. The process should last between a minute to over an hour depending on the file size, the conversion specifics and the computer configuration.

When the conversion process is completed the software will notify you. You will receive an error message at the moment the error took place if a problem occurs. Open the media player of your choice and confirm that the file has been converted correctly.

Do’s

Be careful to select the correct | the relevant | the right} audio and video codecs; WMA for audio and WMV8/9 for a video are select} the best choice.

Be careful to select the relevant video size; usually the original size.

Also, make sure you choose the {right | correct | relevant} bit rate; for decent quality, use at least 128 kbit/s for audio and 768 kbit/s for video.

Keep the frames per second the same as the source file.
