WAV stores audio as uncompressed PCM (Pulse-Code Modulation) samples. There is no encoding algorithm that discards data — every sample captured during recording or conversion is stored verbatim. This means a WAV file decoded on any platform produces bit-for-bit identical audio to the original source, making it the definitive reference format for professional work.

FAQ
Frequently Asked Questions
WAV is uncompressed and has near-universal software support, making it ideal for real-time processing in DAWs. FLAC is smaller on disk but requires decoding. For editing and effects processing, WAV is generally preferred.
No — converting a lossy MP3 to WAV does not recover lost audio data. The WAV file will be larger but the audio quality remains identical to the MP3 source. WAV is useful here for format compatibility, not quality improvement.
44.1 kHz is the CD standard, used for music distribution. 48 kHz is the standard for video, broadcast, and film. Match your project's existing sample rate to avoid conversion artifacts.
16-bit provides 96 dB of dynamic range and is the CD standard. 24-bit provides 144 dB and is used during recording and mixing to preserve headroom. For final delivery, 16-bit is typically fine.
WAV stores every audio sample without compression. A 3-minute stereo WAV at 44.1 kHz / 16-bit is about 30 MB. FLAC compresses the same data losslessly to roughly 15–20 MB. If storage is a concern, consider our FLAC Converter.
Yes. Upload any video file (MP4, MKV, AVI, MOV, etc.) and the tool will extract the audio track and deliver it as a WAV file with your chosen settings.

Complete Guide
WAV Audio: The Professional Standard Explained
WAV (Waveform Audio File Format) has been the bedrock of professional audio production since Microsoft and IBM introduced it in 1991. Decades later it remains the default interchange format for studios, broadcasters, and post-production houses worldwide. Understanding why — and when to use it — helps you make better decisions in every audio workflow.
What Makes WAV Lossless?
Bit Depth: 16-bit vs 24-bit
Bit depth determines the dynamic range of a WAV file. 16-bit provides a theoretical dynamic range of ~96 dB and is the CD standard — more than enough for final consumer delivery. 24-bit provides ~144 dB of dynamic range and is used during recording and mixing to preserve headroom. Most professional DAW projects record at 24-bit to avoid clipping, then dither down to 16-bit for final release. If you are working with audio that will be processed further, always choose 24-bit.
Sample Rate: 44.1 kHz vs 48 kHz
Sample rate sets how many audio snapshots are taken per second. 44,100 Hz (44.1 kHz) is the CD and music distribution standard. 48,000 Hz (48 kHz) is the standard for video, broadcast, and film. If you are converting audio for a video project, always choose 48 kHz to avoid sample rate mismatch when the WAV is imported into a video editor. For music-only projects destined for streaming or CD, 44.1 kHz is the correct choice.
When to Choose WAV Over FLAC
FLAC and WAV are both lossless, but they serve different purposes. WAV is faster to decode in real time, has near-universal software support including legacy tools, and is the mandatory format for many broadcast and post-production deliverables. FLAC is superior for archiving because it is 40–60% smaller. A practical rule: use FLAC for your long-term archive and convert to WAV only when a specific tool or workflow requires it.
Extracting Audio from Video as WAV
One of the most common WAV conversion tasks is extracting an audio track from a video file. Uploading an MP4 or MKV file and receiving a clean WAV output is faster than using a dedicated video editor for the same purpose. The WAV file can then be imported into Audacity, Adobe Audition, or any DAW for detailed editing — dialogue cleanup, noise removal, music replacement, or re-synchronisation before recombining with the video.
