ID3 Tags: Information about the mp3 file can be stored at the end of the file. Many players display this information during playback. The information you can add is: Title, Year, Artist, Album, Comment and Genre. ID3 has a limit of 30 characters for each field.

File Formats

MP3
MP3 is a compressed version of the WAV format and consumes as little as 10% of the hard drive space of an equivalent WAV file - typically 1 MB for a minute of music. The MP3 format compresses audio files in such a way that the file size is relatively small, but the song sounds nearly perfect.

WAV
The WAV format is an uncompressed copy of a CD audio track that preserves CD-quality. Although this is the purest form of audio, it also takes up a significant amount of hard drive space (a typical three-minute song consumes more than 30MB of hard disk space)

WAV ADPCM
Compressed WAV format. ADPCM (Adaptive Differential Pulse Code Modulation) is an audio compression scheme which compresses from 16-bit to 4-bit for a 4:1 compression ratio.

Microsoft ADPCM is directly supported on most Windows implementations as a native format. Although the quality of IMA ADPCM voice files is not great, the files are portable. There is a real advantage in having compact files that can be played on most Windows PCs.

WMA
Windows Media Audio format. A special type of advanced streaming format file for use with audio content encoded with the Windows Media Audio codec. The .wma extension indicates a file format and how the content is encoded.

OGG Vorbis
Ogg Vorbis format. Ogg Vorbis is an audio compression format. It is roughly comparable to other formats used to store and play digital music, such as MP3, VQF, AAC, and other digital audio formats.

Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel.

VOX
Dialogic ADPCM format. The Dialogic ADPCM format is commonly found in telephony applications, and has been optimized for low sample rate voice. It will only save mono 16-bit audio, and like other ADPCM formats, it compresses to 4-bits/sample (for a 4:1 ratio). This format has no header, so any file format with the extension .VOX will be assumed to be in this format.

GSM
Compressed WAV format. Good for keeping of human speech. It is lossy speech compression that allow to get telephone quality speech with 13 kbit/s. It is a standard used for telephone sound compression in European countries and its gaining popularity because of its quality.

GSM 06.10 stands for Global System for Mobile Communications and is a variant of LPC called RPE-LPC (Regular Pulse Excited - Linear Predictive Coder) and is a European standard originally for use in encoding speech for satellite distribution to mobile phones. It can be found in use in various telephony products such as voice mail applications.

DSP
DSP Group's TrueSpeech is a family of high quality, low bit rate, speech compression algorithms which compress speech down to as little as 1/40th its original size. Several different versions of TrueSpeech at different compression rates are available for licensing, from 8.5 Kbps through 3.9 Kbps. All offer excellent communications over a 14.4 Kbps or better modem.

TrueSpeech 8.5 is the 8.5 Kbps member of DSP Group's TrueSpeech family of software products. It is a low complexity speech coder, which is an integral component of Microsoft windows and has also been endorsed by Dialogic for computer telephony products. TrueSpeech 8.5 should be used when compatibility with Microsoft is a prerequisite.

CCUIT G721
Used for computer telephony. 32 kbit/s adaptive differential pulse code modulation (ADPCM). Good for keeping of human speech.

CCUIT G723
Used for computer telephony. Extensions of Recommendation G.721 adaptive differential pulse code modulation to 24 and 40 kbit/s for digital circuit multiplication equipment application. Good for keeping of human speech.

CCUIT G726
Used for computer telephony. 40, 32, 24, 16 kbit/s adaptive differential pulse code modulation (ADPCM). Good for keeping of human speech.

Setting Format Parameters

MP3, OGG Formats
Sample frequency and bitrateThe higher the value of these parameters the better the quality and the bigger the file.The most popular setting for is 44,100Hz 128Kbit.Fixed Bit Rate (FBR) versus Variable Bit Rate (VBR)VBR means the bit rate changes during encoding to produce higher quality sound and bigger file size.
MP3 Presets
The MP3 presets will automatically set frequency, bit rate and quality to match the preset name. Select the preset and click Apply.
OGG Vorbis
This is becoming an increasingly popular format and is said to produce better quality sound than MP3. Encoding time is a little slower. This format is free and open source.
WMA Format
The Windows Media Format has 33 presets giving a range of frequencies and bit rates, stereo and mono.
WAV Format
The WAV format has a large range of frequency and bit rates. You can match this format to another WAV file. From WAV format click Set?, select a wav file and click Open. The frequency and bit rate will be extracted from the file and used in conversions.
Other Formats
Select a frequency for other formats and the information for each format will change to show the setting details for each format.Some formats are not available with certain frequencies and the information for that format will be blank. 
How to judge sound quality
As we get older we gradually lose the ability to hear frequencies from both the top and bottom frequency ranges, so judging sound quality is really up to the individual. Your playback system is also a big factor, small computer speakers do not require the same audio quality as a hi-fi system.
