WAV Compression
Hi all
I got a page from my friend(the author), well, it is really useful for music lovers, so if you are interested in it, you can take a view, thanks! WAV is one of the most commonly used formats for music enthusiasts, which stores two-channel LPCM audio sampled 44,100 times per second with 16 bits per sample. So the quality of the WAV file is almost the same as CD 44.1 kHz, 16-bit stereo, hence, WAV is known as the closest lossless music format. But usually WAV audio will occupy large space, how to compress its size? 1.Reduce audio bitrate to a suitable file size. For example, you can change the bitrate from 160 kbps to 128 kbps. 2. The simplest and most effective way to reduce the size of the audio file is to convert to lossy audio format. As we know, MP3 is a frequently-used lossy format with powerful compatibility. You can convert WAV file to MP3 format for file compression. (Source from http://www.videoconverterfactory.com...-wav-file.html) |
Re: WAV Compression
I find the info on this page suspect at best.
To begin with a .wav file at 44.1 KHz is exactly CD quality not almost the same. Now some people have burnt cd's with mp3 files on them but those are NOT true Redbook cd's. In the #1 section those bitrates are mp3 figures and not numbers for .wav files. There are lossless file compression techniques with better quality than mp3. Overall I call this commercial Spam with no redeeming value and misleading information. |
Re: WAV Compression
Yep and even lossy algorithms such as AAC give better results

This works in a similar way to "zipping" a file. If zip compression destroyed any data programs compressed this way just would not be able to function. It just gets rid of the non-essential data. Its kind of like junk DNA mixed with our regular, usable DNA. The reason why there is "junk DNA" in our files to begin with is it goes back to how files systems work and how information is stored in a file. Its kind of important to the system in part, but not useful for the actual audio or video itself. |
