do wav files use compression?

Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed audio in the linear pulse code modulation (LPCM) format. ... The WAV format supports compressed audio using, on Microsoft Windows, the Audio Compression Manager. Any ACM codec can be used to compress a WAV file.

A lossless file, the FLAC (Free Lossless Audio Codec) is compressed to nearly half the size of an uncompressed WAV or AIFF of equivalent sample rate, but there should be no “loss” in terms of how it sounds. ... Other lossless audio file formats include ALAC (Apple Lossless) and WMA Lossless (Windows Media Audio).

All audio on YouTube is compressed (approximately to around 126 kbps AAC), which in itself isn't such a bad thing; AAC compression can sound ok at relatively low bitrates. It becomes a problem, however, when poorly compressed videos are used as source files – effectively compressing the audio twice.

Digital audio and video has a sample rate, bit depth and bit rate. They are usually compressed to reduce file size and stream more efficiently over networks. Compression can be lossy or lossless.

Windows and Mac are both capable of opening WAV files. For Windows, if you double-click a WAV file, it will open using Windows Media Player. For Mac, if you double-click a WAV, it will open using iTunes or Quicktime. If you're on a system without these programs installed, then consider third-party software.

MP3 in British English abbreviation for. 1. MPEG-1 Audio Layer-3: software that enables files to be compressed quickly to 10% or less of their original size for storage on disk or hard drive or esp for transfer over the internet.

Higher resolution PCM audio formats are mostly used in audio production by audio mixing and mastering engineers. The bit depths for them can go up to 32bits. Such files can be compressed using FLAC format for playback. For example a 192Khz/24 bit stereo PCM audio FLAC encoded file will have a bit rate of 9216kbps.

Reeds don't affect the compression but frayed ones will affect low end and starting.

There are three major groups of audio file formats: Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM; Formats with lossless compression, such as FLAC, Monkey's Audio (filename extension . ape ), WavPack (filename extension .

Simply put, a WAV file (which is PCM audio) is storing much more data than the MP3 file is. MPEG-1 Layer 3 (and many other lossy audio compression codecs) use a different method for encoding audio. Rather than measuring pressure over time, they measure frequency components over a time.

Bitrate has a direct impact on sound quality. When an original recording is compressed into an MP3 file, a lot of information is lost. ... There's no question that CDs sound much better than MP3s. But the real downside of the CD is its lack of portability.

There should be no difference audibly between a lossless format like FLAC and an uncompressed format like AIFF. Plus you get the benefit of a lower storage requirement, somewhere between 30 and 40% less on avaerage. The difference is the size of the files. Lossless files take up half the space of the originals.

CDs offer full 44.1kHz uncompressed digital audio. Here's what that means, according to “What Data Compression Does To Your Music” (Sound On Sound), which offers a very detailed look at the science behind file compression: The audio is stored digitally on a CD via a technique known as PCM, or Pulse Code Modulation.

Compressing files makes them smaller, which has two main advantages: the files take up less storage space, and they transfer more quickly when being sent between computers. In Windows, the in-built way to compress a file is to turn it into a ZIP file, which reduces the file's overall size without losing any data.

Zipping zips is fine. If there is a problem, that would be a bug in the compression software :). You will probably not get any further compression for those files though unless you're using a higher level of compression. Zipping a zip might confuse AV software.

NTFS compression makes files smaller on your hard drive. You can access these files normally – no need for cumbersome zipping and unzipping. Like with all file compression systems, your computer must use additional CPU time for decompression when it opens the file.
