What is a WAV file?
WAV — raw uncompressed audio
Use the format WAV
A concrete example
Provide a working file to editing software or create an MP3 copy for sharing.
Useful checks
Control the sampling rate, channels, and duration. A WAV can be large.
Choose a conversion
Keep the original and open the result in the software or on the device that will need to use it.
Your questions about this format
Which format should you choose to share a recording?
MP3 is a good starting point for sending or casual listening. Select your source, then MP3, start the conversion, and listen to the result. For audio editing, WAV may be more suitable but often produces a larger file.
Does converting an MP3 to a WAV improve the sound?
No: the WAV does not restore the information lost when creating the MP3. It mainly allows you to change the working format. To preserve the maximum quality, start from the original recording when you have it.
How can you compare before downloading?
After a successful audio conversion, use the original and resulting players. Check a quiet area and a loud area, then the beginning and the end. In case of cutoff or absence of sound, keep the original and report the formats used to support.
Why doesn't a MIDI file sound exactly like it does on my system?
A MIDI describes notes and instruments, not a sound recording. Its conversion depends on the sound bank used by the engine. Listen to the rendering before broadcasting; the MIDI synthesis is part of specialized NoLimit processing.
What is it?
WAV compresses nothing: it records the exact value of the signal, tens of thousands of times per second. It's sound as it is, with no filtering whatsoever.
This fidelity comes at a price: one minute of CD-quality stereo takes up about 10 MB. A full album exceeds half a gigabyte.
History & origin
Microsoft and IBM created WAV in 1991 for Windows, building on a generic container structure. Alongside Apple's AIFF, it is one of the two founding formats of digital audio.
It has barely changed since, and remains the reference format for recording studios.
Why it is useful
Flawless quality, with no compression artifacts whatsoever, and instant decoding that requires no processing.
Every audio editing program reads it natively: it's the common language of sound production.
Limits & drawbacks
A considerable file size, poorly suited to emailing or storing on a phone.
Metadata support is poor — a WAV file doesn't properly carry the title, artist, or cover art — and file size is capped at 4 GB, roughly six hours of audio.
Practical tips
Record and edit in WAV, distribute in MP3 or AAC. That's the right order: start from the best and scale down.
To archive losslessly while halving the file size, convert to FLAC instead: the quality is exactly the same, bit for bit.
