MP3 to WAV Converter Online Free — Choose Your Sample Rate

While MP3 is the most popular audio format for distribution and playback, there are many situations where you need to convert MP3 back to WAV:

• Audio editing — most professional DAWs (Ableton, Logic Pro, Pro Tools) work best with uncompressed WAV files
• Video production — video editing software like Premiere Pro and Final Cut Pro prefer WAV for audio tracks
• DJ software compatibility — some DJ setups and hardware require WAV format for certain features
• Re-editing and remixing — working with WAV prevents generation loss from re-encoding compressed audio
• Archival purposes — storing audio in an uncompressed format for long-term preservation

Note: Converting MP3 to WAV does not recover the audio data lost during the original MP3 compression. The output WAV will have the same audio quality as the input MP3, but in an uncompressed container that's compatible with professional software.

Sample rate determines how many audio samples are captured per second. Higher sample rates can capture higher frequencies but result in larger files.

• 44.1 kHz (CD Quality) — The standard for music. Captures frequencies up to 22kHz, well above the human hearing limit of 20kHz. Use this for music production, DJ tracks, and general audio.
• 48 kHz (Professional/Video) — The standard for video production and broadcast. Required by most video editing software and streaming platforms. Use this when your audio will be synced to video.
• 96 kHz (High-Resolution) — Used in high-end studio recording and audiophile applications. Provides extra headroom for processing and pitch shifting. Files are twice the size of 48kHz.

For most use cases, 44.1kHz is the correct choice. Choose 48kHz if you're working with video.

Our converter uses ffmpeg.wasm running entirely in your browser:

1. Upload your MP3 — drag and drop or click to browse
2. Choose sample rate — 44.1kHz, 48kHz, or 96kHz
3. Convert — ffmpeg decodes the MP3 and re-encodes as 16-bit PCM WAV
4. Download — your WAV file is ready immediately

The output is a standard 16-bit PCM WAV file — the most compatible WAV format, accepted by all audio software and hardware.

• Ableton Live / Logic Pro — import WAV for better performance and compatibility with audio effects
• Adobe Premiere / Final Cut Pro — use WAV for video audio tracks (48kHz recommended)
• Serato DJ / Rekordbox — some features like hot cues and waveform analysis work better with WAV
• Podcast editing — edit in WAV for maximum quality before final MP3 export
• Sample creation — extract samples from MP3 tracks and save as WAV for use in samplers
