Wav Vs. Flac: How Different Are They? [Pros & Cons of Each]

It doesn’t matter if you are an audio professional or just an average consumer of audio, sooner or later, as long as you are using audio, you will have to deal with audio formats. There are several audio formats available in the world today for a reason.

Audio formats perform a critical function in the music industry—both on the side of the consumers and suppliers of audio.

Audio formats are pretty important because they can impact the sound quality of sound recordings, the compatibility of different playback devices, and the ease of distribution.

One of the most important things musicians and producers should know is which audio file formats are best suited for different audio applications, such as sound recording, audio mixing, and mastering.

Not just audio engineers, ordinary consumers of audio need to know which audio file format is best for them. This is important because compatibility, sound quality, and ease of transfer will always be an issue for reasons that are quite obvious.

When talking about audio formats, two of the most popular formats that often pop up in lists and debates are wav and Flac. To some, they don’t know the difference between these two formats. On the other hand, some are curious about which of the formats is better.

There has always been a long debate on which is better than the other. In this article, we will look deeper into these two audio formats and clarify their differences and maybe help you decide which is better.

FLAC means “Free Lossless Audio Codec.” Simply, the “lossless” in the name FLAC means that you can compress other audio files into FLAC format to save storage space without losing any of the original audio quality.

FLAC was designed to be able to reduce audio files to about 60% of their original size, by creating audio copies that are way smaller and easier to store or distribute.

On the other hand, wav which stands for Waveform Audio File Format is not so different from FLAC. The major difference is that wav is always uncompressed and thus, always larger in size when compared to FLAC.

LOSSY vs LOSSLESS

If you are confused about lossy and lossless formats. Here is a quick rundown to get you up to speed about these systems.

What Is A Lossy Format?

Lossy audio formats employ compression algorithms that discard some audio data to reduce file sizes significantly.

This data loss is often done in areas of the audio that the human ear is less sensitive to, allowing for a substantial size reduction while maintaining acceptable audio quality for the average listener. Examples of lossy formats include MP3, AAC, and WMA.

What Is A Lossless Format?

Lossless audio formats, such as WAV and FLAC, preserve the original audio quality without any data compression or loss of information.

This means that when you encode an audio file into a lossless format and then decode it back, the resulting audio will be bit-for-bit identical to the original source. This is why lossless formats are preferred in professional audio settings, where the highest level of audio fidelity is essential.

What Are The Differences Between Lossy and Lossless Formats?

There are three main differences between lossy and lossless formats:

Use Cases: Lossless formats are preferred for professional audio tasks, archiving, and situations where audio quality is critical. Lossy formats are more suitable for everyday listening, online streaming, and situations where storage efficiency is a priority.

Audio Quality: The most significant difference between lossless and lossy formats lies in audio quality. Lossless formats, like WAV and FLAC, maintain 100% audio quality, while lossy formats sacrifice some audio data to achieve smaller file sizes. With a lossy format you will not get the same (or sometimes not even close to the same) audio quality as the original.

File Size: Lossless formats have larger file sizes compared to lossy formats. The extent of size reduction depends on the level of compression used in lossy formats. Overall, the difference can be quite significant.

How Are Lossy and Lossless Connected To WAV and FLAC?

Both WAV and FLAC are lossless formats. The difference is that WAV is a completely uncompressed format. This means that WAV will deliver the exact quality as the original file.

FLAC employs a lossless compression technology. So even though the file size is slightly smaller (due to the compression) the audio quality is still just as good as the original.

Compressed vs Uncompressed

When deciding between FLAC and WAV, you are essentially choosing between compressed and uncompressed audio formats.

Depending on what you intend to do, this could make a big difference to your project. Here is what you should keep in mind when choosing between the two.

Uncompressed Audio Format (WAV):

FLAC’s lossless compression offers smaller file sizes without compromising audio quality, making it well-suited for streaming, online distribution, and other tasks.

SAMPLE RATE AND BIT-DEPTH

On the topic of audio formats, you will commonly hear the phrases ‘sample rate’ and ‘bit depth (aka bit rate).’ These are two important things you need to consider when choosing an audio format as they have a direct and profound impact on the quality of the output. Here is what you need to know about these two things.

Sample Rate

The sample rate refers to the number of audio samples taken per second during the recording or playback of digital audio. The sample rate is measured in Hertz (Hz) and commonly represented as kilohertz (kHz), such as 44.1 kHz or 48 kHz.

A higher sample rate allows for a more precise representation of the original audio waveform, especially in capturing high-frequency details and transients. This is because a higher sample rate means you are capturing more information per second of whatever you are recording.

Bit Depth

The bit depth refers to the number of bits used to represent each audio sample. It plays a significant role in the dynamic range and precision of audio data. Common bit depths include 16-bit and 24-bit.

Overall, the bit depth affects the audio’s resolution and how well the audio accurately represents volume levels and subtle audio nuances of the original file. A higher bit depth allows for a wider dynamic range and better signal-to-noise ratio, resulting in higher audio quality.

Free vs Open-Source

In the realm of audio formats, you will also come across the discussion of free vs open-source formats. Here is what you need to know about these two types of formats.

Free Audio Formats:

Free audio formats refer to formats that are available for use without any cost. Users can freely access, distribute, and utilize these formats without the need to pay licensing fees or royalties.

Some examples of free audio formats include WAV (Waveform Audio File Format) and MP3 (MPEG Audio Layer III). WAV is a commonly used format in the audio industry, while MP3 is a popular lossy audio format for online distribution and portable devices.

Open-source Audio Formats:

Open-source audio formats are formats whose source code is made available to the public, allowing users to modify, improve, and customize the format to suit their specific needs.

FLAC (Free Lossless Audio Codec) is an example of an open-source audio format. Its source code is freely available, enabling developers to work on enhancements and customize it according to user-specific implementations.

Which is Better, Wave or Flac? – Verdict

Deciding between WAV and FLAC can be a tough decision. They are both excellent formats (in terms of audio quality) and choosing the right one for you really depends on what your requirements are and what will be most convenient to use in your particular situation.
