What are audio file formats and what do they mean?
An audio file is a file format for storing audio data on a computer. This data can be stored uncompressed or compressed to reduce the file size.

Here are the major groups of file formats:

*Uncompressed: such as WAV and AIFF
WAV: Windows Audio Format. File format extension is .wav. The standard audio file format for CDs, it will take up a lot of hard disk space. Will play back on Windows, Macintosh and Linux operating systems.

AIFF: Audio Interchange File Format. File format extension is .aiff or .aif . Created by Apple, it is used by professional-level audio and video applications. Like any non-compressed format, it uses much more disk space than MP3 about 10MB for one minute of stereo audio at a sample rate of 44.1 kHz and a sample size of 16 bits.

*Lossy compression: such as MP3, WMA and AAC.

MP3: MPEG-1 Audio Layer 3. File format extension is .mp3. It is a common audio format for consumer audio storage, as well as a standard of digital audio compression for the transfer and playback of music on digital audio players. When performing lossy audio encoding, such as creating an MP3 file, there is a trade-off between the amount of space used and the sound quality of the result. Typically, the creator is allowed to set a bit rate, which specifies how many kilobits the file may use per second of audio. Using a lower bit rate provides a relatively lower audio quality and produces a smaller file size. Likewise, using a higher bit rate outputs a higher quality audio, but also results in a larger file.

WMA: Windows Media Audio (WMA). File format extension is .wma.  Is an audio data compression technology developed by Microsoft. It is a proprietary technology that forms part of the Windows Media framework.

AAC: Advanced Audio Coding. File format extension is .aac. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC is best known for being the default audio format for Apple’s iPhone, iPod and iTunes, and is also the standard iTunes Store audio format.

M4A: MPEG-4, also know as MP4. This file format is capable of supporting both audio and video data, and the file extension may be listed as .MP4 or .M4A. It is a popular file format for video files used on portable media players The .M4A extension is commonly used on MPEG-4 files that only contain audio data. Evoca uploads do not support any files containing video information.

*Lossless compression: (not currently supported by Evoca) such as FLAC, Monkey’s Audio (filename extension APE), WavPack (filename extension WV), Shorten, Tom’s lossless Audio Kompressor (TAK), TTA, ATRAC Advanced Lossless, Apple Lossless and Windows Media Audio Lossless (WMA Lossless).

What this means for you:

Now that we support various audio formats, you have the freedom to save a wide range of audio file types to your Evoca Express account. If you are an Apple user you will not have to go through the process of converting your audio recordings to save to your account and then use privately or share with the world using our Flash players: standard players for single recordings are available in your My recordings tableview and you can customize single recording and playlist players using our Flash player wizard.
