The WAV vs. FLAC Contest

You can't deny that choosing the right audio to listen to can be quite challenging, especially if you are just venturing into the vastly fluid world of digital music. Many audio file types are available, and each is screaming for your attention. If choosing was a matter of randomly selecting a file format from a list, it would all be too easy, but unfortunately, there is more to it than meets the eye.

Terms used in explaining audio formats

You probably won't notice much difference in audio quality between the various audio types, but the researcher in you is craving for information. This information is readily available but dressed in terminologies that you have to learn before choosing the best audio file type.

You won't be able to pick the winner in the WAV versus FLAC contest without an appreciation of the basic terms employed in the sphere of digital audio. These terms come in handy when comparing different formats and deciding with a level of accuracy, which audio type beats the others.

Here are the terms that feature prominently in the FLAC vs. WAV debate.

FLAC vs. WAV: Pros and Cons

To determine what is better for you: WAV or FLAC, it is crucial to understand each of these popular audio files.

FLAC is short for Free Lossless Audio Codec. Lossless means that you can compress an uncompressed audio file into FLAC without compromising the original sound quality. FLAC files also support tagging, which is a process of changing an audio file’s information about the composer, album, artist, etc.

WAV stands for Waveform Audio File Format and refers to the audio file format standard developed by Microsoft and IBM for storing audio streams on PC. Unlike FLAC, this audio format is uncompressed, being an exact copy of the source audio.

  • Outstanding sound quality
  • Open-source format
  • Compatible with the majority of modern players
  • Compatible with many media players
  • Easy to edit and tweak
  • Bit-depth and sample rates are unlimited
  • Bit-depth and sample rates are limited
  • Incompatible with some devices
  • The WAV files are usually larger than FLAC files
  • Proprietary format

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 the 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 inconveniencing 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

It is not easy to settle the score between FLAC and WAV since they go head to head on the pedestal of quality. However, you can find out for yourself if one is better than the other by converting from one to the other and listening for the difference. The difference between FLAC and WAV may come out strongly by switching between the two formats.

Pick one audio file in two formats, and play them on your device. Do you notice any difference in quality? Well, convert a FLAC audio to WAV and listen to it in comparison with its source file. This experiment will give you a clear picture of the bruising WAV vs. FLAC debate.

Comparing WAV and FLAC is a tricky affair since both formats experience no loss in quality when processed. However, if storage space is a major concern for you, FLAC would carry the day since its compression reduces its file size to up to 60%. But if all else remains constant, it may be impossible to tell the difference between FLAC and WAV.

Whether you choose WAV or FLAC, keep in mind that you are dealing with high-quality audio. But you can always try to convert from one file to another using an efficient and convenient video converter. If you have no idea where to start when choosing a good video converter, try Movavi Video Converter, and you won't be disappointed.

Frequently Asked Questions

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.

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.

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.
