Free MP3, WAV, WMA, OGG, VOB Encoder and Converter Software Downloads

This list of free MP3 encoder and converter software have a important role, and perhaps without any to download, then the MP3 format known to millions of people for enjoyment probably would be non existent. The average CD audio format for a 3 minute song is about 32 MB in file size. However MP3 encoder software can compress the song to about 3mb or about 10 % of the original, usually with marginal loss in quality. Based on our hearing judgment, the MP3 algorithms can largely eliminate - what we can't hear, a sound that is relatively quieter than another sound when played together, and what sound that we can hear better than other sounds. Encoders essentially remove what we don't need to hear, based largely on perceptual coding.

These free software encoders and converter downloads, take advantage of our perception of hearing, and hence can produce acceptable quality MP3's for listening. The quality depends on the bitrate (often 128 Kbps) but higher can be applied for increased quality, but also increased file size. Most encoders convert WAV format to MP3, but include other formats, e.g. WMA to MP3. Popular encoder engines are Lame, but there is also Xing, BladeEnc, and Fraunhofer encoders.

Though the following software encoders and converters are free, but may become shareware, re-branded, pro versions, etc, and hence in future, might not be hosted at their current web sites, download portals, etc. Best to use their title names to find a site to download the free MP3 software. Note that some MP3/Audio Editors, and CD rippers include encoders either direct from the CD, and stand alone MP3/WAV files.

Lame: Well known freeware file (lame.exe or lame_enc.dll) required for certain software to allow encoding.

"Super" Media File Converter (erightsoft): Simplified Universal Player Encoder, renderer: Supports many formats including video: 3gp/3g2 (Nokia, , Sony, Ericsson, etc) avi, asf, avi (DivX, H263, H263 +, H264, MPEG4, Xvid, etc), dat, flc, flv (Flash) , mkv, mpg (mpeg I, mpeg II), mov (H263, H263 +, H264, MPEG4 etc) mp4 (H263, H263 +, H264, MPEG4), qt, rm, ram, ogg rmvb, (Play Station), swf (Flash), ts (HDTV), vob, wmv, etc. Just too much!

The above free encoder and converter software downloads are generally easy to operate, but maximum efficiency can be gained by tweaking any optional settings to generate a quality MP3 sound. Setting the bit rate to 128Kbps will generally produce a good sound output for regular use. Perhaps set to the higher 192Kbps if you are particular about a certain MP3 sound, and don't mind a larger file size.

To help distinguish between the two preceding bit rates, you can also set to variable bit rate (VBR) to automatically maximize encoding during more complex sound sectors (e.g. brass instruments). This will produce a more defined quality MP3 sound for some listeners to enjoy.
