WAV vs. FLAC: key differences
What is the FLAC format?
In order to understand the differences between WAV vs. FLAC and figure out the best option for you in the WAV versus FLAC debate, you need to know the details of each file format. So let's begin with a breakdown of what FLAC is to help you find out if FLAC or WAV is right for you.
FLAC stands for Free Lossless Audio Codec. In simple terms, the "lossless" part of the name means that you can compress other audio files into FLAC format to save space without losing any of the original sound quality.
This is one of the big advantages of FLAC, which was developed by the Xiph.Org Foundation and released in 2001. It was designed to be able to reduce audio files to around 60% of their original size, creating copies that are way smaller and easier to store or send.
As stated, those smaller and more versatile FLAC files still retain identical levels of quality. Other advantages of FLAC in the .wav vs .flac debate include the fact that it's a free and open-source format, so you can tinker around with it however you like.
In terms of compatibility, FLAC is also compatible with the vast majority of modern media players, so you shouldn't encounter any problems with running FLAC files. However, there are some compatibility issues with certain devices, and bit-depth and sample rates with FLAC are limited, so this format isn't perfect. You can convert WAV to FLAC if you need to.
- Excellent sound quality
- Lossless compression for easy sharing and storage
- Works on most devices
- Free and open source
- Some compatibility issues may occur
- Bit-depth and sample rate limitations
What is the WAV format?
So, should you pick WAV or FLAC for your next audio project or download? And is WAV better than FLAC? Well, in order to understand if FLAC or WAV is better, you need to also have a thorough understanding of what WAV is and how it compares.
WAV is technically known as Waveform Audio File Format and can appear with the extension .wav or .wave, so may be referred to as either WAV or WAVE, and is pronounced like the word "Wave" in either case.
This audio format was developed by IBM and Microsoft and was originally designed for storing audio bitstreams on Windows PCs. It's been the primary audio format for storing uncompressed audio on Windows devices since its release back in 1991 and is also the standard format used on CDs.
So, what's the difference between WAV and FLAC? Well, aside from the fact that WAV is a lot older, it's another big difference between FLAC and WAV is that WAV is an uncompressed format. This means that WAV files tend to be much bigger than FLAC files.
Since it is uncompressed, WAV also performs very well in terms of pure quality and bitrate, with no limitations on things like bit-depth. So, from a technical standpoint, WAV can be seen as a slight winner in the FLAC vs. WAV quality and FLAC vs. WAV bitrate debates.
WAV, however, is not open-source. It's a proprietary format, so it is less open to modification and development. Also, as explained earlier, the files for this format can be quite large and difficult to work with at times. So, in terms of FLAC vs. WAV size, FLAC is the winner.
However, compatibility isn't an issue with WAV, like it can be with FLAC. You can play WAV files on almost any device and they're compatible with pretty much all media players and types of software, too.
- Impeccable quality levels
- No restrictions on bit-depth or quality
- Almost universal compatibility
- Easy to work with
- Big file sizes
- Not open source
- Now that we know what these formats are, let’s take a look at key differences between them.
Lossy and lossless
Lossy audio files lose some quality when they are compressed or converted from one form to another. Lossless, on the other hand, refers to those audio formats that report a negligible loss in quality when compressed or transferred to other formats. Since both FLAC and WAV are lossless, it becomes even more challenging to answer the question: is FLAC or WAV better?
Compressed and uncompressed
Choosing FLAC or WAV also means you are selecting between compressed and uncompressed formats. One significant difference between FLAC and WAV is that while the former is compressed, the latter is an exact copy of the original audio file. Converting an audio file to FLAC means you are compressing it to occupy less space compared to WAV, but without any noticeable loss in quality. So, if storage space is your main concern, choose FLAC over WAV because it achieves up to 60% compression of the source file.
Sample rate and bit depth
You need to understand the concepts of sample rate and bit depth to know how audio formats work. The sample rate and bit depth tell you how accurate a piece of digitally recorded sound can be. Without going into technicalities, it is important at the onset to state that the higher the sample rate and bit depth, the higher the quality of the piece of audio in question.
Sample rates are expressed in Hertz or kilohertz while bit depth exists in bits. The sample rate refers to how many times an audio rendering software samples the audio file within a second. If the sample rate is high, say 194kHz, it means the software samples the music 194,000 times in a second and can read lots of information from this piece.
The rendering software may draw on 16 or 24 bits of information to accurately describe an audio file. Computer geeks describe this phenomenon as the bit depth. A high bit depth, such as 32 bits, translates to higher quality audio than a lower bit depth of 8 bits.
So, how does the FLAC vs. WAV contest shape up in the light of this information? By being uncompressed, WAV loses nothing in quality but occupies more space on your device, while FLAC is compressed and may lose certain details of the file during compression. However, you won't notice any bump in quality since FLAC is lossless.
Free and open-source
FLAC appears to beat WAV hands down on this front. The former is available for free and can be modified because it is open-source, unlike the latter, patented by Microsoft. So, if you are looking for an audio format you may wish to tinker around with, go for FLAC.
However, that is not to say WAV is inferior to FLAC. If you are not satisfied with WAV, you can still convert it to FLAC with a good video converter such as Movavi Video Editor. Though it is a video editor, it has options for converting audio files as well, hence the most convenient choice for those who wish to switch between audio formats.
Whether to choose FLAC or WAV may be no easy task. The two audio file formats are almost similar. The only difference is that one is compressed while the other isn't. It may boil down to personal preferences in using and storing media.
What about storage?
If you compare WAV and FLAC in terms of storage space, you will find that FLAC occupies less space due to compression. WAV will take up more space on your device, take longer to transfer between devices, and download it, which may be quite inconvenient to some users. So, if you want to choose WAV or FLAC, storage may be a significant factor coming into play.
Converting between WAV and FLAC
So, is WAV or FLAC better? Well, both of these formats have their pros and cons, but you don't have to choose between them. You can make use of a converter app or tool, like Movavi Video Converter, to easily convert audio files from one format to the other.
Even though Movavi Video Converter is primarily designed for video conversion, it works just as well with converting audio files, too. Here's how to do it:

So, if you've been wondering about the differences between WAV and FLAC or want to know which one is best, we hope that this guide has provided the information you need. Both FLAC and WAV have their own unique features, and both can be great to use and work with.
Frequently asked questions
Which is better: WAV or FLAC?
The main difference between these two formats is compression. WAV files are uncompressed, which is great for audio editing. However, WAV files also take a lot of space. FLAC files are compressed, so they take less space than WAV and are better suited for storing music.
What is the best format for audio quality?
Lossless audio formats such as FLAC, WAV, or AIFF provide the best sound quality. Their only disadvantage is the size: lossless files tend to be significantly larger than lossy ones.
Does converting FLAC to WAV lose quality?
Both WAV and FLAC are lossless audio formats. It means that converting FLAC to WAV or vice versa won’t lose audio quality. You can easily switch between FLAC, WAV, and more than 180 other formats with Movavi Video Converter.
Does FLAC sound better than WAV?
No, FLAC and WAV files sound almost identical, as WAV files are uncompressed as FLAC files are lossless. So there's no real difference between them in terms of pure audio quality.
MP3 or WAV for YouTube: which is better?
It's best to use WAV for YouTube, as YouTube automatically compresses audio, which can lead to losses in quality. MP3 is a more compressed audio format than WAV and so the quality may be reduced even further when uploading to YouTube.
