Convert MP3 to WAV — Batch MP3 to WAV Converter

Some software simply will not touch MP3 — older audio editors, certain broadcast systems, and most CD-burning tools expect uncompressed WAV. Total Audio Converter converts MP3 to WAV in batch — point it at a folder and every file comes out as a standard WAV that any editor, sampler, or burning program accepts.

Quick answer: To convert MP3 to WAV, install Total Audio Converter, select your MP3 files, choose WAV as the output format, then click Start. The whole folder converts offline in one batch, with no file-count limit and no quality lost beyond what the original MP3 already discarded.

MP3 vs WAV: What Is the Difference?

MP3 is a compressed, lossy format — it discards audio data to keep files small. Once that data is gone, it cannot be recovered. WAV is an uncompressed container: no further data is lost when you convert to it, but the file also will not shrink or improve beyond the quality already baked into the source MP3.

Converting MP3 to WAV does not restore lost audio detail — it repackages the existing MP3 audio into a format that older or professional software can actually open, edit, or burn to disc. This is the standard first step before importing audio into a DAW, a video editor, or a CD-burning tool that does not read MP3 directly.

How to Convert MP3 to WAV

• Step 1. Launch Total Audio Converter. The left panel shows a folder tree for quick navigation.
• Step 2. Browse to the folder that holds your MP3 files.
• Step 3. Check the files you want, or click Check All to select the whole folder.
• Step 4. Click WAV in the format toolbar at the top of the window.
• Step 5. Choose the sample rate and bit depth if needed, and select a destination folder.
• Step 6. Press Start. Total Audio Converter writes a WAV for every MP3 file.

Each MP3 file becomes a separate WAV. The original files are never modified, and you can convert hundreds of files in a single pass.

Command-Line Conversion

Total Audio Converter includes a command-line interface for converting MP3 without the GUI. Example:

AudioConverter.exe C:\Music\*.mp3 C:\Output\ -c WAV

Wrap this in a .bat file or a scheduled task to convert MP3 files automatically — useful for prepping a batch of files for a CD-burning tool or a DAW import.

Total Audio Converter Customer Reviews 2026

"My sampler only reads WAV and half my reference tracks are MP3. Batch converting a whole folder before a session takes seconds instead of dragging files one at a time into a converter plugin."

Nathan Cole Home Studio Producer

"Our playout system rejects MP3 outright. Converting the week's submissions to WAV in one batch before they go into the schedule has cut a recurring headache down to one click."

Diane Foss Community Radio Volunteer

"Burning a proper audio CD for an older client meant converting a whole playlist to WAV first. Doing the entire folder in one pass instead of track by track saved real time on a tight timeline."
