Settings guide
Sample rate selection:
- ·44100 Hz (44.1 kHz) — The standard for music, CD-quality audio, and consumer content. Use this unless you have a specific reason not to.
- ·48000 Hz (48 kHz) — The broadcast and video standard. Use this when the WAV will be synced to video or submitted to a platform with 48 kHz requirements (YouTube, broadcast TV, podcast platforms that specify 48 kHz).
Bit depth:
- ·16-bit — CD standard. Sufficient for the final delivered file. 96 dB dynamic range covers virtually all real-world audio needs.
- ·24-bit — Production standard. More headroom during editing and processing. Use 24-bit if the WAV will be further processed in a DAW before final export.
Practical guidance:
- ·If the MP3 was recorded at 44.1 kHz, export WAV at 44.1 kHz — no benefit to upsampling.
- ·If the file goes into a video project, use 48 kHz regardless of the MP3's original sample rate.
- ·WAV files are large: 1 minute of stereo 44.1 kHz 16-bit WAV ≈ 10 MB. Budget storage accordingly for long files.
Format comparison
WAV vs AIFF: Both are lossless uncompressed formats. WAV is the universal standard (reads on Windows, Mac, Linux, every DAW). AIFF is Apple's equivalent — functionally identical but primarily found in Apple ecosystems. Either works for editing; WAV has broader compatibility.
WAV vs FLAC: FLAC compresses audio losslessly to roughly 40–60% the size of WAV while preserving identical quality. For archiving or transfer, FLAC is more efficient. For DAW import and direct playback compatibility, WAV works everywhere. If your tools support FLAC, it is the better archive format; if you need universal compatibility, WAV wins.
Converting MP3 to WAV vs converting MP3 to FLAC: The output quality is identical — you cannot improve MP3's quality by changing its container. The choice is purely about file size and compatibility. WAV is larger but universally readable; FLAC is smaller but requires software that supports it.
How it works
Upload
Drop your MP3 file. The converter reads the format and displays file properties.
Set output options
Choose sample rate (44.1 kHz for music, 48 kHz for video sync) and bit depth (16 or 24-bit).
Convert
The MP3 is decoded and re-wrapped as uncompressed WAV entirely in your browser.
Download
Save the WAV file. Import it directly into your DAW or audio editor.
About this format
MP3 and WAV serve fundamentally different purposes. MP3 is a delivery format — it discards audio data that psychoacoustic models predict you won't notice, achieving file sizes 10–12× smaller than uncompressed audio at acceptable quality. WAV is a production format — uncompressed PCM that preserves every sample, making it the format of choice for editing, processing, and broadcast delivery.
Converting MP3 to WAV does not restore the audio data that MP3 discarded. The perceptual coding that removed high-frequency detail and stereo complexity is irreversible. What you get is the MP3's audio placed in an uncompressed container — identical sound quality to the source MP3, but in a format that every professional audio tool reads natively.
The reasons to do this conversion are practical, not quality-based. Digital Audio Workstations (DAWs) like Logic Pro, Pro Tools, Ableton, and Audacity handle WAV natively and efficiently. More importantly, if you plan to trim, process, apply effects, and re-export an MP3, each encode-decode cycle introduces additional quality degradation. Converting to WAV first lets you work in a lossless editing chain: MP3 → WAV → edit → WAV → final export. One lossy step at import; none during editing.
