AUDIOCRIP

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 Audio 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”

2. FLAC 2. APE 3. WV 4. TAK 5. TTA 6. WMA

List of “lossy compression format”

3. 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 and 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 iTunes 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.

Compact Discs or CDs are the most common multimedia used for storing digital data, particularly digital audio and video. The process of creating these CDs as we know it today involves many steps and procedures. One of the most important steps in the production of CDs, particularly an audio CD, is mastering.

Mastering is the final procedure where the last creative touches can be made on the material, whether video or audio, before it is ready to be replicated. Mastering usually makes the difference between a professional sounding audio CD and an amateurish one. All songs that are released today are mastered extensively to create the best playback sound possible.

Mastering is a combination of several techniques and processes. It usually involves putting the songs or tracks in order. Afterwards, the volume of all the tracks is leveled. The time between the tracks is adjusted and the finishing touches on the intros and ends of the tracks, such as crossfades, are finalized. The sound quality of the tracks is also tested.

Mastering can be accomplished in several ways. In record labels, a professional CD mastering engineer works on mastering the record using state-of-the-art mastering facilities. This mastering equipment is designed to produce the best playback and ensure that the mix is free from slight inconsistencies.

Mastering Using Free CD Mastering Software

CD mastering can also be done at home using special mastering software. For budding artists, this is a cheap and easy way to create their own CDS or demos. Free CD mastering programs are available that can be used to do basic mastering jobs. The quality of the CDs mastered through the use of free mastering software will depend on the skill of the one doing the mastering and the capabilities of the program used. Nevertheless, free CD mastering software is the cheapest way to master your own CDs.

When looking for free Catholic Bibles it is important to keep in mind several factors. For example, it must be a Bible which contains the Deutero-Canonical Books (referred to by others as Apocryphal). In addition, one must decide what type of Bible is desired. A print Bible? An audio Bible? In this article, I will discuss the best places to find free Catholic Bibles.

In terms of a print version, the most obvious translations that come to mind are the New American Bible and the New Revised Standard Version. These texts each contain all of the books recognized by the Roman Catholic Church as scripture. The New American Bible is an explicitly Catholic translation, whereas the New Revised Standard Version is an ecumenical translation amenable to both Catholic and non-Catholic readers alike. I am unaware of any possibility of getting a free hard copy, print version of these translations; however, print versions are viewable online. For the best place to view the New American Bible online for free, I would recommend the website of the United States Conference of Catholic Bishops. Not only does this site contain the New American Bible, but also this text is broken down into lectionary readings for each day making this site unique for free Catholic Bibles.

For an online viewable text of the New Revised Standard Version, the best site is Bible.Oremus.org. The text is not nearly as easy to use as other online Bibles that I have viewed; however, it is difficult to find the New Revised Standard Version elsewhere. This translation is often the preferred one for academic discourse and as such is highly respectable. Thus, while the interface may not be very pleasing, it is worth dealing with the site to read this version for free.

Finally, it is also possible to get a free audio version of these texts. Whether unfortunately or not, the free versions are available by means of a trial. Through a trial program the entire New American Bible is available as a free download. In contrast, only the New Testament books are available for the New Revised Standard version, still free with trial. I am unaware of any sites that might stream audio of these texts for free though this a common practice with many of the Protestant translations. Thus, a trial may be the best and only way to listen to free Catholic Bibles in audio format.
