Why Compress WAV Files?

Here we list three typical examples in order to better understand why people want to compress WAV files:

I am required by a distance education language course to record some audio and submit it. However, they are being absolutely unreasonable. I am only allowed to attach a file that is 5mb while my recording is 17mb. I have to compress the WAV file but don't want to lose much quality.

I want to use WAV format and then get more than 15 songs to a CD. Anyway to compress WAV files without loss their quality?

Is there any way I can compress these wav files so as not to lose too much audio quality but also regain a fair bit of valuable disk space?

Reason: people want to submit or upload WAV files to special website which has limitation on the size of file being uploaded, or save space such as computer hard disk, CD, and players and so on, or some other special reasons.

Note: Do not lower too much, otherwise the quality will lose.

Method two Compress WAV to other audio format
In this method, you can compress WAV to lossless compressed audio formats like FLAC, Apple Lossless (filename extension m4a), etc or compress WAV to lossy compressed audio formats such as MP2, MP3, OGG Vorbis, AAC, AC3, and DTS and so on.

How: Click "Profile" drop-down button of WAV Compressor to choose the listed formats from "General Audio" or "Lossless Audio" category.

Many formats also support adjust Sample Size and Sample Rate like in Method One. If you convert WAV to lossy format, you can set Bitrate in Advanced Settings to get different compression rate and quality.
