FLAC vs. WAV: The Battle of the Audio File Formats

Music and audio are now essential elements of entertainment. Whether it's preserving cherished family videos or experiencing a fantastic theater show, the quality of sound plays a significant role in how enjoyable the experience is for listeners. Two well-known sound formats, FLAC and WAV, have been circulating online for years, and experts and enthusiasts continue to debate which is superior in terms of overall performance. Finally, we may have an answer to this long-standing question.

What is FLAC?

FLAC, or Free Lossless Audio Codec, is a popular digital audio format where files are compressed without losing data or quality. FLAC files are generally encoded at a bit depth of 16 or 24 bits and a sampling rate of up to 192 kHz, which makes them ideal for high-quality audio playback. In addition to this, FLAC files are compatible with relevant metadata that can be displayed by audio players, making it easier to manage and organize any audio collection.

Pros of Using FLAC:

  • It compresses audio files without compromising quality.
  • FLAC files are highly compatible and can be played by various devices and audio players.
  • It can support high-resolution video of up to 24-bit/192 kHz.
  • FLAC can store metadata such as the anime of the album, track title, artist's name, and so on.
  • It is an open-source solution.
  • FLAC files are nearly indistinguishable from WAV audio files.

Cons of Using FLAC:

  • Older players do not support this audio file format.
  • They are not very suitable for streaming.
  • They require higher CPU usage for decoding and encoding processes.

What is WAV?

WAV stands for Waveform Audio File Format. It is another widely used uncompressed digital sound format developed by Microsoft in collaboration with IBM. Because a WAV file produces high-quality outputs, it is popularly used in various professional audio applications. Unlike older, compressed audio formats like MP3 and AAC, WAV does not lose any data or quality while encoding the sound. As such, the file sizes are relatively larger. With a typical bit depth of 16 bits (maximum 32 bits) and a sampling rate of up to 192 kHz, WAV files are efficient at producing high-quality outputs.

Pros of Using WAV:

  • It is an uncompressed format with no potential loss in quality.
  • Very suitable for professional applications.
  • Both Windows and MacOS support it.
  • Supports inclusion of metadata.

Cons of Using WAV:

  • File sizes are comparatively larger than compressed audio file formats.
  • There is limited support for high-resolution audio.
  • They pose larger storage requirements.

FLAC vs. WAV: Key Differences

Getting a deeper understanding of both audio formats requires a detailed head-to-head comparison.

Here are the key differentiating factors that can settle the FLAC vs. WAV debate:

Basis of Comparison WAV FLAC
File Size The file size is generally larger. FLAC files are typically smaller in comparison.
Compression It is an uncompressed digital audio format. It provides lossless compression; files are compressed without affecting the audio quality.
Quality It produces high-quality sound. It produces high-quality sound.
Compatibility It is widely supported by all devices and software as it is an older format. It is widely supported by newer platforms. But incompatible with many old audio players.
Sampling Rate Up to 192 kHz Up to 192 kHz
Bit Depth It supports bit depths of 8, 16, 24, and 32 bits. It supports bit depths of 8, 16, and 24 bits.
Bit Rate The bit rate varies depending on the bit depth and sample rate used for a specific file. It supports variable bit rates that typically range between 800 kbps and 1,400 kbps.
Licensing Proprietary; therefore, paid. Free and open source.

File Size

FLAC files are undoubtedly smaller and require less storage because it is a compressed file format. WAV, on the other hand, is uncompressed. This implies that a WAV file contains all the original data without any changes. To give you an idea, a typical three-minute WAV file at 44.1 kHz and 16-bit depth would be around 32 MB in size. In FLAC format, the same file can be compressed to 12 MB.


FLAC files use lossless compression. This means that audio files are compressed but don't lose any quality or data. WAV files, on the other hand, are completely uncompressed.


There is not much to separate between WAV and FLAC in terms of quality, as both file formats can provide high-quality and high-fidelity sounds.


WAV is supported by all major platforms, including the old ones. FLAC also enjoys good compatibility options. However, because it is newer, it might not be supported by traditional players and software.

Sampling Rate and Bit Depth

The higher the sampling rate and bit depth, the better the overall performance, as it gives a better and more representation of the original audio signal. Both WAV and FLAC can support sampling rates of up to 192 kHz. WAV supports bit depths up to 32 bits. FLAC, on the other hand, only supports up to 24 bits.

Bit Rate

Bitrate of FLAC and WAV

The higher the bit rates, the better the sound quality. However, higher bit rates also result in larger file sizes. The bit rates supported by either audio format depend on the sampling rates and bit depths. For a typical WAV file, the bit rate can be between 353 kbps for an 8-bit mono file at a sampling rate of 8 kHz to 9.2 MBPS for a 32-bit stereo file with a sampling rate of 192 kHz. On the other hand, FLAC files typically have bit rates between 800 kbps and 1,400 kbps.


WAV is a proprietary audio format. This implies that licensing fees may be required if it is to be used for certain applications. That is why it is the standard for professional use only. FLAC, on the other hand, is completely free and open-source.

Which is the Best Audio Format for Streaming?

For streaming, both FLAC and WAV have their own benefits and drawbacks. For example, WAV files offer a high-quality listening experience. But they are also bigger in size as the format is uncompressed. Thus, streaming WAV files will require more bandwidth and can be slower. FLAC files, on the other hand, are compressed and smaller in size. While they don't require as much bandwidth, they do demand more processing power to complete the decompressing process.

Overall, FLAC is considered the more suitable format because it enables faster streaming and produces higher-quality sound. However, the ultimate choice also depends on several other factors, such as users' specific requirements, the condition of their devices, and the platforms they use for streaming.
